Fluorescent Imaging Plate Reader (FLIPR) Assay: Orexin antagonist activity was determined by measuring changes in intracellular calcium levels using a Ca2+ sensitive fluorescent dye. The changes in fluorescent signal were monitored by Fluorescent Imaging Plate Reader (FLIPR®) technology available from Molecular Devices, LLC, U.S.A. Orexin mediated increases in intracellular Ca2+ concentration were readily detected upon activation with orexin-A. Twenty-four hours prior to the assay, RBL-2H3 cells stably expressing either human orexin receptor 1 or human orexin receptor 2 were seeded in cell culture medium in black, clear-bottom 384-well plates (commercially available from Corning Inc., U.S.A.) and grown overnight at 37 °C., 5% CO2. On the day of the assay, cell culture media was removed and cells were loaded with Calcium 5 Dye (commercially sold by Molecular Devices, LLC, U.S.A.) for 1 hour at 37 °C., 5% CO2.Fluorescent Imaging Plate Reader (FLIPR) Assay: Orexin antagonist activity was determined by measuring changes in intracellular calcium levels using a Ca2+ sensitive fluorescent dye.

The cells are seeded at 20,000 cells/well into 384-well black clear bottom sterile plates (Greiner). The seeded plates are incubated overnight at 37° C. in 5% CO2. Human orexin-A as an agonist is prepared as 1 mM stock solution in MeOH:water (1:1), diluted in HBSS containing 0.1% bovine serum albumin (BSA), NaHCO3: 0.375 g/L and 20 mM HEPES for use in the assay at a final concentration of 3 nM. Antagonists are prepared as 10 mM stock solution in DMSO, then diluted in 384-well plates using DMSO followed by a transfer of the dilutions into in HBSS containing 0.1% bovine serum albumin (BSA), NaHCO3: 0.375 g/L and 20 mM HEPES. On the day of the assay, 50 μL of staining buffer (HBSS containing 1% FCS, 20 mM HEPES, NaHCO3: 0.375 g/L, 5 mM probenecid (Sigma) and 3 μM of the fluorescent calcium indicator fluo-4 AM (1 mM stock solution in DMSO, containing 10% pluronic) is added to each well. The 384-well cell-plates are incubated for 50 min at 37° C. in 5% CO2 followed by equilibration at rt for 30 min before measurement. Within the Fluorescent Imaging Plate Reader (FLIPR Tetra, Molecular Devices), antagonists are added to the plate in a volume of 10 μL/well, incubated for 120 min and finally 10 μL/well of agonist is added. Fluorescence is measured for each well at 1 second intervals, and the height of each fluorescence peak is compared to the height of the fluorescence peak induced by 3 nM orexin-A with vehicle in place of antagonist.Intracellular Calcium Assay: Chinese hamster ovary (CHO) cells expressing the human orexin-1 receptor and the human orexin-2 receptor, respectively, are grown in culture medium (Ham F-12 with L-Glutamine) containing 300 μg/mL G418, 100 U/mL penicillin, 100 μg/mL streptomycin and 10% heat inactivated fetal calf serum (FCS).

Orexin mediated increases in intracellular Ca2+ concentration were readily detected upon activation with orexin-A. Twenty-four hours prior to the assay, RBL-2H3 cells stably expressing either human orexin receptor 1 or human orexin receptor 2 were seeded in cell culture medium in black, clear-bottom 384-well plates (commercially available from Corning Inc., U.S.A.) and grown overnight at 37 °C., 5% CO2. On the day of the assay, cell culture media was removed and cells were loaded with Calcium 5 Dye (commercially sold by Molecular Devices, LLC, U.S.A.) for 1 hour at 37 °C., 5% CO2.Fluorescent Imaging Plate Reader (FLIPR) Assay: Orexin antagonist activity was determined by measuring changes in intracellular calcium levels using a Ca2+ sensitive fluorescent dye.

Twenty-four hours prior to the assay, RBL-2H3 cells stably expressing either human orexin receptor 1 or human orexin receptor 2 were seeded in cell culture medium in black, clear-bottom 384-well plates (commercially available from Corning Inc., U.S.A.) and grown overnight at 37 °C., 5% CO2. On the day of the assay, cell culture media was removed and cells were loaded with Calcium 5 Dye (commercially sold by Molecular Devices, LLC, U.S.A.) for 1 hour at 37 °C., 5% CO2.

Fluorescent Imaging Plate Reader (FLIPR) Assay: Orexin antagonist activity was determined by measuring changes in intracellular calcium levels using a Ca2+ sensitive fluorescent dye. The changes in fluorescent signal were monitored by Fluorescent Imaging Plate Reader (FLIPR®) technology available from Molecular Devices, LLC, U.S.A. Orexin mediated increases in intracellular Ca2+ concentration were readily detected upon activation with orexin-A. Twenty-four hours prior to the assay, RBL-2H3 cells stably expressing either human orexin receptor 1 or human orexin receptor 2 were seeded in cell culture medium in black, clear-bottom 384-well plates (commercially available from Corning Inc., U.S.A.) and grown overnight at 37 °C., 5% CO2. On the day of the assay, cell culture media was removed and cells were loaded with Calcium 5 Dye (commercially sold by Molecular Devices, LLC, U.S.A.) for 1 hour at 37 °C., 5% CO2.Fluorescent Imaging Plate Reader (FLIPR) Assay: Orexin antagonist activity was determined by measuring changes in intracellular calcium levels using a Ca2+ sensitive fluorescent dye.

Intracellular Calcium Assay: Chinese hamster ovary (CHO) cells expressing the human orexin-1 receptor and the human orexin-2 receptor, respectively, are grown in culture medium (Ham F-12 with L-Glutamine) containing 300 μg/mL G418, 100 U/mL penicillin, 100 μg/mL streptomycin and 10% heat inactivated fetal calf serum (FCS). The cells are seeded at 20,000 cells/well into 384-well black clear bottom sterile plates (Greiner). The seeded plates are incubated overnight at 37° C. in 5% CO2. Human orexin-A as an agonist is prepared as 1 mM stock solution in MeOH:water (1:1), diluted in HBSS containing 0.1% bovine serum albumin (BSA), NaHCO3: 0.375 g/L and 20 mM HEPES for use in the assay at a final concentration of 3 nM. Antagonists are prepared as 10 mM stock solution in DMSO, then diluted in 384-well plates using DMSO followed by a transfer of the dilutions into in HBSS containing 0.1% bovine serum albumin (BSA), NaHCO3: 0.375 g/L and 20 mM HEPES. On the day of the assay, 50 μL of staining buffer (HBSS containing 1% FCS, 20 mM HEPES, NaHCO3: 0.375 g/L, 5 mM probenecid (Sigma) and 3 μM of the fluorescent calcium indicator fluo-4 AM (1 mM stock solution in DMSO, containing 10% pluronic) is added to each well. The 384-well cell-plates are incubated for 50 min at 37° C. in 5% CO2 followed by equilibration at rt for 30 min before measurement. Within the Fluorescent Imaging Plate Reader (FLIPR Tetra, Molecular Devices), antagonists are added to the plate in a volume of 10 μL/well, incubated for 120 min and finally 10 μL/well of agonist is added. Fluorescence is measured for each well at 1 second intervals, and the height of each fluorescence peak is compared to the height of the fluorescence peak induced by 3 nM orexin-A with vehicle in place of antagonist.Intracellular Calcium Assay: Chinese hamster ovary (CHO) cells expressing the human orexin-1 receptor and the human orexin-2 receptor, respectively, are grown in culture medium (Ham F-12 with L-Glutamine) containing 300 μg/mL G418, 100 U/mL penicillin, 100 μg/mL streptomycin and 10% heat inactivated fetal calf serum (FCS).

FLIPR Ca2+ Flux Assay: Chinese hamster ovary (CHO) cells expressing the rat orexin-1 receptor or the human orexin-2 receptor, are grown in Iscove's modified DMEM containing 2 mM L-glutamine, 0.5 g/ml G418, 1% hypoxanthine-thymidine supplement, 100 U/ml penicillin, 100 ug/ml streptomycin and 10% heat-inactivated fetal calf serum (FCS). The cells are seeded at 20,000 cells/well into Becton-Dickinson black 384-well clear bottom sterile plates coated with poly-D-lysine. All reagents were from GIBCO-Invitrogen Corp. The seeded plates are incubated overnight at 37° C. and 5% CO2. Ala-6,12 human orexin-A as the agonist is prepared as a 1 mM stock solution in 1% bovine serum albumin (BSA) and diluted in assay buffer (HBSS containing 20 mM HEPES, 0.1% BSA and 2.5 mM probenecid, pH7.4) for use in the assay at a final concentration of 70 pM. Test compounds are prepared as 10 mM stock solution in DMSO, then diluted in 384-well plates, first in DMSO, then assay buffer. On the day of the assay, cells are washed 3 times with 100 ul assay buffer and then incubated for 60 min (37° C., 5% CO2) in 60 ul assay buffer containing 1 uM Fluo-4AM ester, 0.02% pluronic acid, and 1% BSA.

Orexin mediated increases in intracellular Ca2+ concentration were readily detected upon activation with orexin-A. Twenty-four hours prior to the assay, RBL-2H3 cells stably expressing either human orexin receptor 1 or human orexin receptor 2 were seeded in cell culture medium in black, clear-bottom 384-well plates (commercially available from Corning Inc., U.S.A.) and grown overnight at 37 °C., 5% CO2. On the day of the assay, cell culture media was removed and cells were loaded with Calcium 5 Dye (commercially sold by Molecular Devices, LLC, U.S.A.) for 1 hour at 37 °C., 5% CO2.Fluorescent Imaging Plate Reader (FLIPR) Assay: Orexin antagonist activity was determined by measuring changes in intracellular calcium levels using a Ca2+ sensitive fluorescent dye.

Intracellular Calcium Assay: Chinese hamster ovary (CHO) cells expressing the human orexin-1 receptor and the human orexin-2 receptor, respectively, are grown in culture medium (Ham F-12 with L-Glutamine) containing 300 μg/mL G418, 100 U/mL penicillin, 100 μg/mL streptomycin and 10% heat inactivated fetal calf serum (FCS). The cells are seeded at 20,000 cells/well into 384-well black clear bottom sterile plates (Greiner). The seeded plates are incubated overnight at 37° C. in 5% CO2. Human orexin-A as an agonist is prepared as 1 mM stock solution in MeOH:water (1:1), diluted in HBSS containing 0.1% bovine serum albumin (BSA), NaHCO3: 0.375 g/L and 20 mM HEPES for use in the assay at a final concentration of 3 nM. Antagonists are prepared as 10 mM stock solution in DMSO, then diluted in 384-well plates using DMSO followed by a transfer of the dilutions into in HBSS containing 0.1% bovine serum albumin (BSA), NaHCO3: 0.375 g/L and 20 mM HEPES. On the day of the assay, 50 μL of staining buffer (HBSS containing 1% FCS, 20 mM HEPES, NaHCO3: 0.375 g/L, 5 mM probenecid (Sigma) and 3 μM of the fluorescent calcium indicator fluo-4 AM (1 mM stock solution in DMSO, containing 10% pluronic) is added to each well. The 384-well cell-plates are incubated for 50 min at 37° C. in 5% CO2 followed by equilibration at rt for 30 min before measurement. Within the Fluorescent Imaging Plate Reader (FLIPR Tetra, Molecular Devices), antagonists are added to the plate in a volume of 10 μL/well, incubated for 120 min and finally 10 μL/well of agonist is added. Fluorescence is measured for each well at 1 second intervals, and the height of each fluorescence peak is compared to the height of the fluorescence peak induced by 3 nM orexin-A with vehicle in place of antagonist.Intracellular Calcium Assay: Chinese hamster ovary (CHO) cells expressing the human orexin-1 receptor and the human orexin-2 receptor, respectively, are grown in culture medium (Ham F-12 with L-Glutamine) containing 300 μg/mL G418, 100 U/mL penicillin, 100 μg/mL streptomycin and 10% heat inactivated fetal calf serum (FCS).

Intracellular Calcium Assay: Chinese hamster ovary (CHO) cells expressing the human orexin-1 receptor and the human orexin-2 receptor, respectively, are grown in culture medium (Ham F-12 with L-Glutamine) containing 300 μg/mL G418, 100 U/mL penicillin, 100 μg/mL streptomycin and 10% heat inactivated fetal calf serum (FCS). The cells are seeded at 20,000 cells/well into 384-well black clear bottom sterile plates (Greiner). The seeded plates are incubated overnight at 37° C. in 5% CO2. Human orexin-A as an agonist is prepared as 1 mM stock solution in MeOH:water (1:1), diluted in HBSS containing 0.1% bovine serum albumin (BSA), NaHCO3: 0.375 g/L and 20 mM HEPES for use in the assay at a final concentration of 3 nM. Antagonists are prepared as 10 mM stock solution in DMSO, then diluted in 384-well plates using DMSO followed by a transfer of the dilutions into in HBSS containing 0.1% bovine serum albumin (BSA), NaHCO3: 0.375 g/L and 20 mM HEPES. On the day of the assay, 50 μL of staining buffer (HBSS containing 1% FCS, 20 mM HEPES, NaHCO3: 0.375 g/L, 5 mM probenecid (Sigma) and 3 μM of the fluorescent calcium indicator fluo-4 AM (1 mM stock solution in DMSO, containing 10% pluronic) is added to each well. The 384-well cell-plates are incubated for 50 min at 37° C. in 5% CO2 followed by equilibration at rt for 30 min before measurement. Within the Fluorescent Imaging Plate Reader (FLIPR Tetra, Molecular Devices), antagonists are added to the plate in a volume of 10 μL/well, incubated for 120 min and finally 10 μL/well of agonist is added. Fluorescence is measured for each well at 1 second intervals, and the height of each fluorescence peak is compared to the height of the fluorescence peak induced by 3 nM orexin-A with vehicle in place of antagonist.Intracellular Calcium Assay: Chinese hamster ovary (CHO) cells expressing the human orexin-1 receptor and the human orexin-2 receptor, respectively, are grown in culture medium (Ham F-12 with L-Glutamine) containing 300 μg/mL G418, 100 U/mL penicillin, 100 μg/mL streptomycin and 10% heat inactivated fetal calf serum (FCS).

Intracellular Calcium Assay: Chinese hamster ovary (CHO) cells expressing the human orexin-1 receptor and the human orexin-2 receptor, respectively, are grown in culture medium (Ham F-12 with L-Glutamine) containing 300 μg/mL G418, 100 U/mL penicillin, 100 μg/mL streptomycin and 10% heat inactivated fetal calf serum (FCS). The cells are seeded at 20,000 cells/well into 384-well black clear bottom sterile plates (Greiner). The seeded plates are incubated overnight at 37° C. in 5% CO2. Human orexin-A as an agonist is prepared as 1 mM stock solution in MeOH:water (1:1), diluted in HBSS containing 0.1% bovine serum albumin (BSA), NaHCO3: 0.375 g/L and 20 mM HEPES for use in the assay at a final concentration of 3 nM. Antagonists are prepared as 10 mM stock solution in DMSO, then diluted in 384-well plates using DMSO followed by a transfer of the dilutions into in HBSS containing 0.1% bovine serum albumin (BSA), NaHCO3: 0.375 g/L and 20 mM HEPES. On the day of the assay, 50 μL of staining buffer (HBSS containing 1% FCS, 20 mM HEPES, NaHCO3: 0.375 g/L, 5 mM probenecid (Sigma) and 3 μM of the fluorescent calcium indicator fluo-4 AM (1 mM stock solution in DMSO, containing 10% pluronic) is added to each well. The 384-well cell-plates are incubated for 50 min at 37° C. in 5% CO2 followed by equilibration at rt for 30 min before measurement. Within the Fluorescent Imaging Plate Reader (FLIPR Tetra, Molecular Devices), antagonists are added to the plate in a volume of 10 μL/well, incubated for 120 min and finally 10 μL/well of agonist is added. Fluorescence is measured for each well at 1 second intervals, and the height of each fluorescence peak is compared to the height of the fluorescence peak induced by 3 nM orexin-A with vehicle in place of antagonist.Intracellular Calcium Assay: Chinese hamster ovary (CHO) cells expressing the human orexin-1 receptor and the human orexin-2 receptor, respectively, are grown in culture medium (Ham F-12 with L-Glutamine) containing 300 μg/mL G418, 100 U/mL penicillin, 100 μg/mL streptomycin and 10% heat inactivated fetal calf serum (FCS).

The cells are seeded at 20,000 cells/well into 384-well black clear bottom sterile plates (Greiner). The seeded plates are incubated overnight at 37° C. in 5% CO2. Human orexin-A as an agonist is prepared as 1 mM stock solution in MeOH:water (1:1), diluted in HBSS containing 0.1% bovine serum albumin (BSA), NaHCO3: 0.375 g/L and 20 mM HEPES for use in the assay at a final concentration of 3 nM. Antagonists are prepared as 10 mM stock solution in DMSO, then diluted in 384-well plates using DMSO followed by a transfer of the dilutions into in HBSS containing 0.1% bovine serum albumin (BSA), NaHCO3: 0.375 g/L and 20 mM HEPES. On the day of the assay, 50 μL of staining buffer (HBSS containing 1% FCS, 20 mM HEPES, NaHCO3: 0.375 g/L, 5 mM probenecid (Sigma) and 3 μM of the fluorescent calcium indicator fluo-4 AM (1 mM stock solution in DMSO, containing 10% pluronic) is added to each well. The 384-well cell-plates are incubated for 50 min at 37° C. in 5% CO2 followed by equilibration at rt for 30 min before measurement. Within the Fluorescent Imaging Plate Reader (FLIPR Tetra, Molecular Devices), antagonists are added to the plate in a volume of 10 μL/well, incubated for 120 min and finally 10 μL/well of agonist is added. Fluorescence is measured for each well at 1 second intervals, and the height of each fluorescence peak is compared to the height of the fluorescence peak induced by 3 nM orexin-A with vehicle in place of antagonist.Intracellular Calcium Assay: Chinese hamster ovary (CHO) cells expressing the human orexin-1 receptor and the human orexin-2 receptor, respectively, are grown in culture medium (Ham F-12 with L-Glutamine) containing 300 μg/mL G418, 100 U/mL penicillin, 100 μg/mL streptomycin and 10% heat inactivated fetal calf serum (FCS).

Human orexin-A as an agonist is prepared as 1 mM stock solution in MeOH:water (1:1), diluted in HBSS containing 0.1% bovine serum albumin (BSA), NaHCO3: 0.375 g/L and 20 mM HEPES for use in the assay at a final concentration of 3 nM. Antagonists are prepared as 10 mM stock solution in DMSO, then diluted in 384-well plates using DMSO followed by a transfer of the dilutions into in HBSS containing 0.1% bovine serum albumin (BSA), NaHCO3: 0.375 g/L and 20 mM HEPES. On the day of the assay, 50 μL of staining buffer (HBSS containing 1% FCS, 20 mM HEPES, NaHCO3: 0.375 g/L, 5 mM probenecid (Sigma) and 3 μM of the fluorescent calcium indicator fluo-4 AM (1 mM stock solution in DMSO, containing 10% pluronic) is added to each well. The 384-well cell-plates are incubated for 50 min at 37° C. in 5% CO2 followed by equilibration at rt for 30 min before measurement. Within the Fluorescent Imaging Plate Reader (FLIPR Tetra, Molecular Devices), antagonists are added to the plate in a volume of 10 μL/well, incubated for 120 min and finally 10 μL/well of agonist is added. Fluorescence is measured for each well at 1 second intervals, and the height of each fluorescence peak is compared to the height of the fluorescence peak induced by 3 nM orexin-A with vehicle in place of antagonist.Intracellular Calcium Assay: Chinese hamster ovary (CHO) cells expressing the human orexin-1 receptor and the human orexin-2 receptor, respectively, are grown in culture medium (Ham F-12 with L-Glutamine) containing 300 μg/mL G418, 100 U/mL penicillin, 100 μg/mL streptomycin and 10% heat inactivated fetal calf serum (FCS).

Intracellular Calcium Assay: Chinese hamster ovary (CHO) cells expressing the human orexin-1 receptor and the human orexin-2 receptor, respectively, are grown in culture medium (Ham F-12 with L-Glutamine) containing 300 μg/mL G418, 100 U/mL penicillin, 100 μg/mL streptomycin and 10% heat inactivated fetal calf serum (FCS). The cells are seeded at 20,000 cells/well into 384-well black clear bottom sterile plates (Greiner). The seeded plates are incubated overnight at 37° C. in 5% CO2. Human orexin-A as an agonist is prepared as 1 mM stock solution in MeOH:water (1:1), diluted in HBSS containing 0.1% bovine serum albumin (BSA), NaHCO3: 0.375 g/L and 20 mM HEPES for use in the assay at a final concentration of 3 nM. Antagonists are prepared as 10 mM stock solution in DMSO, then diluted in 384-well plates using DMSO followed by a transfer of the dilutions into in HBSS containing 0.1% bovine serum albumin (BSA), NaHCO3: 0.375 g/L and 20 mM HEPES.

The 384-well cell-plates are incubated for 50 min at 37° C. in 5% CO2 followed by equilibration at rt for 30 min before measurement. Within the Fluorescent Imaging Plate Reader (FLIPR Tetra, Molecular Devices), antagonists are added to the plate in a volume of 10 μL/well, incubated for 120 min and finally 10 μL/well of agonist is added. Fluorescence is measured for each well at 1 second intervals, and the height of each fluorescence peak is compared to the height of the fluorescence peak induced by 3 nM orexin-A with vehicle in place of antagonist.Intracellular Calcium Assay: Chinese hamster ovary (CHO) cells expressing the human orexin-1 receptor and the human orexin-2 receptor, respectively, are grown in culture medium (Ham F-12 with L-Glutamine) containing 300 μg/mL G418, 100 U/mL penicillin, 100 μg/mL streptomycin and 10% heat inactivated fetal calf serum (FCS).

FLIPR Ca2+ Flux Assay: Chinese hamster ovary (CHO) cells expressing the rat orexin-1 receptor or the human orexin-2 receptor, are grown in Iscove's modified DMEM containing 2 mM L-glutamine, 0.5 g/ml G418, 1% hypoxanthine-thymidine supplement, 100 U/ml penicillin, 100 ug/ml streptomycin and 10% heat-inactivated fetal calf serum (FCS). The cells are seeded at 20,000 cells/well into Becton-Dickinson black 384-well clear bottom sterile plates coated with poly-D-lysine. All reagents were from GIBCO-Invitrogen Corp. The seeded plates are incubated overnight at 37° C. and 5% CO2. Ala-6,12 human orexin-A as the agonist is prepared as a 1 mM stock solution in 1% bovine serum albumin (BSA) and diluted in assay buffer (HBSS containing 20 mM HEPES, 0.1% BSA and 2.5 mM probenecid, pH7.4) for use in the assay at a final concentration of 70 pM. Test compounds are prepared as 10 mM stock solution in DMSO, then diluted in 384-well plates, first in DMSO, then assay buffer. On the day of the assay, cells are washed 3 times with 100 ul assay buffer and then incubated for 60 min (37° C., 5% CO2) in 60 ul assay buffer containing 1 uM Fluo-4AM ester, 0.02% pluronic acid, and 1% BSA. The dye loading solution is then aspirated and cells are washed 3 times with 100 ul assay buffer. 30 ul of that same buffer is left in each well. Within the Fluorescent Imaging Plate Reader (FLIPR, Molecular Devices), test compounds are added to the plate in a volume of 25 ul, incubated for 5 min and finally 25 ul of agonist is added. Fluorescence is measured for each well at 1 second intervals for 5 minutes and the height of each fluorescence peak is compared to the height of the fluorescence peak induced by 70 pM Ala-6,12 orexin-A with buffer in place of antagonist.FLIPR Ca2+ Flux Assay: Chinese hamster ovary (CHO) cells expressing the rat orexin-1 receptor or the human orexin-2 receptor, are grown in Iscove's modified DMEM containing 2 mM L-glutamine, 0.5 g/ml G418, 1% hypoxanthine-thymidine supplement, 100 U/ml penicillin, 100 ug/ml streptomycin and 10% heat-inactivated fetal calf serum (FCS).

Ala-6,12 human orexin-A as the agonist is prepared as a 1 mM stock solution in 1% bovine serum albumin (BSA) and diluted in assay buffer (HBSS containing 20 mM HEPES, 0.1% BSA and 2.5 mM probenecid, pH7.4) for use in the assay at a final concentration of 70 pM. Test compounds are prepared as 10 mM stock solution in DMSO, then diluted in 384-well plates, first in DMSO, then assay buffer. On the day of the assay, cells are washed 3 times with 100 ul assay buffer and then incubated for 60 min (37° C., 5% CO2) in 60 ul assay buffer containing 1 uM Fluo-4AM ester, 0.02% pluronic acid, and 1% BSA. The dye loading solution is then aspirated and cells are washed 3 times with 100 ul assay buffer. 30 ul of that same buffer is left in each well. Within the Fluorescent Imaging Plate Reader (FLIPR, Molecular Devices), test compounds are added to the plate in a volume of 25 ul, incubated for 5 min and finally 25 ul of agonist is added. Fluorescence is measured for each well at 1 second intervals for 5 minutes and the height of each fluorescence peak is compared to the height of the fluorescence peak induced by 70 pM Ala-6,12 orexin-A with buffer in place of antagonist.

FLIPR Ca2+ Flux Assay: Chinese hamster ovary (CHO) cells expressing the rat orexin-1 receptor or the human orexin-2 receptor, are grown in Iscove's modified DMEM containing 2 mM L-glutamine, 0.5 g/ml G418, 1% hypoxanthine-thymidine supplement, 100 U/ml penicillin, 100 ug/ml streptomycin and 10% heat-inactivated fetal calf serum (FCS). The cells are seeded at 20,000 cells/well into Becton-Dickinson black 384-well clear bottom sterile plates coated with poly-D-lysine. All reagents were from GIBCO-Invitrogen Corp. The seeded plates are incubated overnight at 37° C. and 5% CO2. Ala-6,12 human orexin-A as the agonist is prepared as a 1 mM stock solution in 1% bovine serum albumin (BSA) and diluted in assay buffer (HBSS containing 20 mM HEPES, 0.1% BSA and 2.5 mM probenecid, pH7.4) for use in the assay at a final concentration of 70 pM. Test compounds are prepared as 10 mM stock solution in DMSO, then diluted in 384-well plates, first in DMSO, then assay buffer. On the day of the assay, cells are washed 3 times with 100 ul assay buffer and then incubated for 60 min (37° C., 5% CO2) in 60 ul assay buffer containing 1 uM Fluo-4AM ester, 0.02% pluronic acid, and 1% BSA. The dye loading solution is then aspirated and cells are washed 3 times with 100 ul assay buffer. 30 ul of that same buffer is left in each well. Within the Fluorescent Imaging Plate Reader (FLIPR, Molecular Devices), test compounds are added to the plate in a volume of 25 ul, incubated for 5 min and finally 25 ul of agonist is added. Fluorescence is measured for each well at 1 second intervals for 5 minutes and the height of each fluorescence peak is compared to the height of the fluorescence peak induced by 70 pM Ala-6,12 orexin-A with buffer in place of antagonist.FLIPR Ca2+ Flux Assay: Chinese hamster ovary (CHO) cells expressing the rat orexin-1 receptor or the human orexin-2 receptor, are grown in Iscove's modified DMEM containing 2 mM L-glutamine, 0.5 g/ml G418, 1% hypoxanthine-thymidine supplement, 100 U/ml penicillin, 100 ug/ml streptomycin and 10% heat-inactivated fetal calf serum (FCS).

Intracellular Calcium Assay: Chinese hamster ovary (CHO) cells expressing the human orexin-1 receptor and the human orexin-2 receptor, respectively, are grown in culture medium (Ham F-12 with L-Glutamine) containing 300 μg/mL G418, 100 U/mL penicillin, 100 μg/mL streptomycin and 10% heat inactivated fetal calf serum (FCS). The cells are seeded at 20,000 cells/well into 384-well black clear bottom sterile plates (Greiner). The seeded plates are incubated overnight at 37° C. in 5% CO2. Human orexin-A as an agonist is prepared as 1 mM stock solution in MeOH:water (1:1), diluted in HBSS containing 0.1% bovine serum albumin (BSA), NaHCO3: 0.375 g/L and 20 mM HEPES for use in the assay at a final concentration of 3 nM. Antagonists are prepared as 10 mM stock solution in DMSO, then diluted in 384-well plates using DMSO followed by a transfer of the dilutions into in HBSS containing 0.1% bovine serum albumin (BSA), NaHCO3: 0.375 g/L and 20 mM HEPES. On the day of the assay, 50 μL of staining buffer (HBSS containing 1% FCS, 20 mM HEPES, NaHCO3: 0.375 g/L, 5 mM probenecid (Sigma) and 3 μM of the fluorescent calcium indicator fluo-4 AM (1 mM stock solution in DMSO, containing 10% pluronic) is added to each well. The 384-well cell-plates are incubated for 50 min at 37° C. in 5% CO2 followed by equilibration at rt for 30 min before measurement. Within the Fluorescent Imaging Plate Reader (FLIPR Tetra, Molecular Devices), antagonists are added to the plate in a volume of 10 μL/well, incubated for 120 min and finally 10 μL/well of agonist is added. Fluorescence is measured for each well at 1 second intervals, and the height of each fluorescence peak is compared to the height of the fluorescence peak induced by 3 nM orexin-A with vehicle in place of antagonist.Intracellular Calcium Assay: Chinese hamster ovary (CHO) cells expressing the human orexin-1 receptor and the human orexin-2 receptor, respectively, are grown in culture medium (Ham F-12 with L-Glutamine) containing 300 μg/mL G418, 100 U/mL penicillin, 100 μg/mL streptomycin and 10% heat inactivated fetal calf serum (FCS).

Fluorescent Imaging Plate Reader (FLIPR) Assay: Orexin antagonist activity was determined by measuring changes in intracellular calcium levels using a Ca2+ sensitive fluorescent dye. The changes in fluorescent signal were monitored by Fluorescent Imaging Plate Reader (FLIPR®) technology available from Molecular Devices, LLC, U.S.A. Orexin mediated increases in intracellular Ca2+ concentration were readily detected upon activation with orexin-A. Twenty-four hours prior to the assay, RBL-2H3 cells stably expressing either human orexin receptor 1 or human orexin receptor 2 were seeded in cell culture medium in black, clear-bottom 384-well plates (commercially available from Corning Inc., U.S.A.) and grown overnight at 37 °C., 5% CO2. On the day of the assay, cell culture media was removed and cells were loaded with Calcium 5 Dye (commercially sold by Molecular Devices, LLC, U.S.A.) for 1 hour at 37 °C., 5% CO2.Fluorescent Imaging Plate Reader (FLIPR) Assay: Orexin antagonist activity was determined by measuring changes in intracellular calcium levels using a Ca2+ sensitive fluorescent dye.

Fluorescent Imaging Plate Reader (FLIPR) Assay: Orexin antagonist activity was determined by measuring changes in intracellular calcium levels using a Ca2+ sensitive fluorescent dye. The changes in fluorescent signal were monitored by Fluorescent Imaging Plate Reader (FLIPR®) technology available from Molecular Devices, LLC, U.S.A. Orexin mediated increases in intracellular Ca2+ concentration were readily detected upon activation with orexin-A. Twenty-four hours prior to the assay, RBL-2H3 cells stably expressing either human orexin receptor 1 or human orexin receptor 2 were seeded in cell culture medium in black, clear-bottom 384-well plates (commercially available from Corning Inc., U.S.A.) and grown overnight at 37 °C., 5% CO2. On the day of the assay, cell culture media was removed and cells were loaded with Calcium 5 Dye (commercially sold by Molecular Devices, LLC, U.S.A.) for 1 hour at 37 °C., 5% CO2.Fluorescent Imaging Plate Reader (FLIPR) Assay: Orexin antagonist activity was determined by measuring changes in intracellular calcium levels using a Ca2+ sensitive fluorescent dye.

Fluorescent Imaging Plate Reader (FLIPR) Assay: Orexin antagonist activity was determined by measuring changes in intracellular calcium levels using a Ca2+ sensitive fluorescent dye. The changes in fluorescent signal were monitored by Fluorescent Imaging Plate Reader (FLIPR®) technology available from Molecular Devices, LLC, U.S.A. Orexin mediated increases in intracellular Ca2+ concentration were readily detected upon activation with orexin-A. Twenty-four hours prior to the assay, RBL-2H3 cells stably expressing either human orexin receptor 1 or human orexin receptor 2 were seeded in cell culture medium in black, clear-bottom 384-well plates (commercially available from Corning Inc., U.S.A.) and grown overnight at 37 °C., 5% CO2. On the day of the assay, cell culture media was removed and cells were loaded with Calcium 5 Dye (commercially sold by Molecular Devices, LLC, U.S.A.) for 1 hour at 37 °C., 5% CO2.Fluorescent Imaging Plate Reader (FLIPR) Assay: Orexin antagonist activity was determined by measuring changes in intracellular calcium levels using a Ca2+ sensitive fluorescent dye.

The changes in fluorescent signal were monitored by Fluorescent Imaging Plate Reader (FLIPR®) technology available from Molecular Devices, LLC, U.S.A. Orexin mediated increases in intracellular Ca2+ concentration were readily detected upon activation with orexin-A. Twenty-four hours prior to the assay, RBL-2H3 cells stably expressing either human orexin receptor 1 or human orexin receptor 2 were seeded in cell culture medium in black, clear-bottom 384-well plates (commercially available from Corning Inc., U.S.A.) and grown overnight at 37 °C., 5% CO2. On the day of the assay, cell culture media was removed and cells were loaded with Calcium 5 Dye (commercially sold by Molecular Devices, LLC, U.S.A.) for 1 hour at 37 °C., 5% CO2.Fluorescent Imaging Plate Reader (FLIPR) Assay: Orexin antagonist activity was determined by measuring changes in intracellular calcium levels using a Ca2+ sensitive fluorescent dye.

The cells are seeded at 20,000 cells/well into Becton-Dickinson black 384-well clear bottom sterile plates coated with poly-D-lysine. All reagents were from GIBCO-Invitrogen Corp. The seeded plates are incubated overnight at 37° C. and 5% CO2. Ala-6,12 human orexin-A as the agonist is prepared as a 1 mM stock solution in 1% bovine serum albumin (BSA) and diluted in assay buffer (HBSS containing 20 mM HEPES, 0.1% BSA and 2.5 mM probenecid, pH7.4) for use in the assay at a final concentration of 70 pM. Test compounds are prepared as 10 mM stock solution in DMSO, then diluted in 384-well plates, first in DMSO, then assay buffer.

Intracellular Calcium Assay: Chinese hamster ovary (CHO) cells expressing the human orexin-1 receptor and the human orexin-2 receptor, respectively, are grown in culture medium (Ham F-12 with L-Glutamine) containing 300 μg/mL G418, 100 U/mL penicillin, 100 μg/mL streptomycin and 10% heat inactivated fetal calf serum (FCS). The cells are seeded at 20,000 cells/well into 384-well black clear bottom sterile plates (Greiner). The seeded plates are incubated overnight at 37° C. in 5% CO2. Human orexin-A as an agonist is prepared as 1 mM stock solution in MeOH:water (1:1), diluted in HBSS containing 0.1% bovine serum albumin (BSA), NaHCO3: 0.375 g/L and 20 mM HEPES for use in the assay at a final concentration of 3 nM. Antagonists are prepared as 10 mM stock solution in DMSO, then diluted in 384-well plates using DMSO followed by a transfer of the dilutions into in HBSS containing 0.1% bovine serum albumin (BSA), NaHCO3: 0.375 g/L and 20 mM HEPES. On the day of the assay, 50 μL of staining buffer (HBSS containing 1% FCS, 20 mM HEPES, NaHCO3: 0.375 g/L, 5 mM probenecid (Sigma) and 3 μM of the fluorescent calcium indicator fluo-4 AM (1 mM stock solution in DMSO, containing 10% pluronic) is added to each well. The 384-well cell-plates are incubated for 50 min at 37° C. in 5% CO2 followed by equilibration at rt for 30 min before measurement. Within the Fluorescent Imaging Plate Reader (FLIPR Tetra, Molecular Devices), antagonists are added to the plate in a volume of 10 μL/well, incubated for 120 min and finally 10 μL/well of agonist is added. Fluorescence is measured for each well at 1 second intervals, and the height of each fluorescence peak is compared to the height of the fluorescence peak induced by 3 nM orexin-A with vehicle in place of antagonist.Intracellular Calcium Assay: Chinese hamster ovary (CHO) cells expressing the human orexin-1 receptor and the human orexin-2 receptor, respectively, are grown in culture medium (Ham F-12 with L-Glutamine) containing 300 μg/mL G418, 100 U/mL penicillin, 100 μg/mL streptomycin and 10% heat inactivated fetal calf serum (FCS).

Intracellular Calcium Assay: Chinese hamster ovary (CHO) cells expressing the human orexin-1 receptor and the human orexin-2 receptor, respectively, are grown in culture medium (Ham F-12 with L-Glutamine) containing 300 μg/mL G418, 100 U/mL penicillin, 100 μg/mL streptomycin and 10% heat inactivated fetal calf serum (FCS). The cells are seeded at 20,000 cells/well into 384-well black clear bottom sterile plates (Greiner). The seeded plates are incubated overnight at 37° C. in 5% CO2. Human orexin-A as an agonist is prepared as 1 mM stock solution in MeOH:water (1:1), diluted in HBSS containing 0.1% bovine serum albumin (BSA), NaHCO3: 0.375 g/L and 20 mM HEPES for use in the assay at a final concentration of 3 nM. Antagonists are prepared as 10 mM stock solution in DMSO, then diluted in 384-well plates using DMSO followed by a transfer of the dilutions into in HBSS containing 0.1% bovine serum albumin (BSA), NaHCO3: 0.375 g/L and 20 mM HEPES. On the day of the assay, 50 μL of staining buffer (HBSS containing 1% FCS, 20 mM HEPES, NaHCO3: 0.375 g/L, 5 mM probenecid (Sigma) and 3 μM of the fluorescent calcium indicator fluo-4 AM (1 mM stock solution in DMSO, containing 10% pluronic) is added to each well. The 384-well cell-plates are incubated for 50 min at 37° C. in 5% CO2 followed by equilibration at rt for 30 min before measurement. Within the Fluorescent Imaging Plate Reader (FLIPR Tetra, Molecular Devices), antagonists are added to the plate in a volume of 10 μL/well, incubated for 120 min and finally 10 μL/well of agonist is added. Fluorescence is measured for each well at 1 second intervals, and the height of each fluorescence peak is compared to the height of the fluorescence peak induced by 3 nM orexin-A with vehicle in place of antagonist.Intracellular Calcium Assay: Chinese hamster ovary (CHO) cells expressing the human orexin-1 receptor and the human orexin-2 receptor, respectively, are grown in culture medium (Ham F-12 with L-Glutamine) containing 300 μg/mL G418, 100 U/mL penicillin, 100 μg/mL streptomycin and 10% heat inactivated fetal calf serum (FCS).

Antagonistic Activity Assay: The antagonistic activities of the test compounds on human orexin-1 receptor (hOX1R) and orexin-2 receptor (hOX2R) were measured by modifying from the method described in literature (Toshikatsu Okumura et al., Biochemical and Biophysical Research Communications 280, 976-981, 2001). Chinese hamster ovary (CHO) cells forcibly expressing the hOX1R and hOX2R were seeded into a 96 well Black clear bottom plate (Nunc) at 20,000 cells per well, which were cultured in Ham's F-12 medium containing 0.1 mM MEM non-essential amino acids, 0.5 mg/ml G418, 10% fetal bovine serum (all by Invitrogen) for 16 hours under the conditions of 37° C., 5% CO2. After removing the medium, 100 uL of 0.5 uM Fluo-4AM ester (Dojin) in an assay buffer (25 mM HEPES (Dojin), Hank's balanced salt solution (Invitrogen), 0.1% bovine serum albumin, 2.5 mM probenecid, 200 ug/ml Amaranth (all by Sigma-Aldrich), pH 7.4) was added and the cells were incubated for 60 minutes at 37° C., 5% CO2.

The final concentration of DMSO in the reactions is equal to or less than 0.1%. Total and nonspecific binding was determined in the absence and presence of 10 uM almorexant. The total volume of each reaction is 200 uL (20 uL of diluted compounds, 80 uL of [3H]-(1-(5-(2-fluoro-phenyl)-2-methyl-thiazol-4-yl)-1-((S)-2-(5-phenyl-(1,3,4)oxadiazol-2-ylmethyl)-pyrrolidin-1-yl)-methanone) diluted in PBS and 100 uL of the cell suspension). Reactions were run for 60 min at room temperature and terminated by filtration through GF/C filter plates (PerkinElmer, Cat. #6005174) presoaked in 0.3% polyethylenimine using the cell harvester (PerkinElmer Filtermate). The plates were washed 3 times by aspirating 30 ml PBS through the plates. Plates were dried in 55° C. oven for 60 min, scintillation fluid was added, and the radioactivity was counted on a Topcount (Packard).

Cells were resuspended in PBS in the presence of 1 tablet of protease inhibitor cocktail (Roche, Cat. #11836145001) per 50 mL. Each cell pellet from a 15 cm plate was resuspended in 10 mL, stored on ice, and homogenized for 45 sec prior to addition to the reactions. Competition binding experiments in 96 well polypropylene plates were performed using [3H]-SB674042 (Moraveck Corporation, specific activity=35.3 Ci/mmol), diluted to a 10 nM concentration in PBS (4 nM final). Compounds were solubilized in 100% DMSO (Acros Organics, Cat. #61042-1000) and tested over a range of 7 concentrations (from 0.1 nM to 10 uM). The final concentration of DMSO in the reactions is equal to or less than 0.1%. Total and nonspecific binding was determined in the absence and presence of 10 uM almorexant. The total volume of each reaction is 200 uL (20 uL of diluted compounds, 80 uL of [3H]-(1-(5-(2-fluoro-phenyl)-2-methyl-thiazol-4-yl)-1-((S)-2-(5-phenyl-(1,3,4)oxadiazol-2-ylmethyl)-pyrrolidin-1-yl)-methanone) diluted in PBS and 100 uL of the cell suspension). Reactions were run for 60 min at room temperature and terminated by filtration through GF/C filter plates (PerkinElmer, Cat. #6005174) presoaked in 0.3% polyethylenimine using the cell harvester (PerkinElmer Filtermate). The plates were washed 3 times by aspirating 30 ml PBS through the plates. Plates were dried in 55° C. oven for 60 min, scintillation fluid was added, and the radioactivity was counted on a Topcount (Packard).Radioligand Binding Assay: Human Embryonic Kidney 293 cells (HEK293) stably expressing rat orexin 1 receptor (Genebank accession number NM_001525) or Chinese ovary cells (CHO) stably expressing human orexin 1 receptor (Genebank accession number NM_001526) were grown to confluency in DMEM (Hyclone, cat #SH30022), 10% FBS, 1x Pen/Strep, 1x sodium pyruvate, 10 mM HEPES, 600 ug/mL G418 and DMEM/F12 (Gibco, Cat #11039), 10% FBS, 1x Pen/Strep, 600 ug/mL G418 media, respectively on 150 cm^2 tissue culture plates, washed with 5 mM EDTA in PBS (HyClone Dulbecco's Phosphate Buffered Saline 1x with Calcium and Magnesium, Cat #SH30264.01, hereafter referred to simply as PBS) and scraped into 50 ml tubes.

Competition binding experiments in 96 well polypropylene plates were performed using [3H]-SB674042 (Moraveck Corporation, specific activity=35.3 Ci/mmol), diluted to a 10 nM concentration in PBS (4 nM final). Compounds were solubilized in 100% DMSO (Acros Organics, Cat. #61042-1000) and tested over a range of 7 concentrations (from 0.1 nM to 10 uM). The final concentration of DMSO in the reactions is equal to or less than 0.1%. Total and nonspecific binding was determined in the absence and presence of 10 uM almorexant. The total volume of each reaction is 200 uL (20 uL of diluted compounds, 80 uL of [3H]-(1-(5-(2-fluoro-phenyl)-2-methyl-thiazol-4-yl)-1-((S)-2-(5-phenyl-(1,3,4)oxadiazol-2-ylmethyl)-pyrrolidin-1-yl)-methanone) diluted in PBS and 100 uL of the cell suspension). Reactions were run for 60 min at room temperature and terminated by filtration through GF/C filter plates (PerkinElmer, Cat. #6005174) presoaked in 0.3% polyethylenimine using the cell harvester (PerkinElmer Filtermate). The plates were washed 3 times by aspirating 30 ml PBS through the plates. Plates were dried in 55° C. oven for 60 min, scintillation fluid was added, and the radioactivity was counted on a Topcount (Packard).

After centrifugation (2KxG, 5 min at 4° C.), the supernatant was aspirated and the pellets frozen and stored at -80\°C. Cells were resuspended in PBS in the presence of 1 tablet of protease inhibitor cocktail (Roche, Cat. #11836145001) per 50 mL. Each cell pellet from a 15 cm plate was resuspended in 10 mL, stored on ice, and homogenized for 45 sec prior to addition to the reactions. Competition binding experiments in 96 well polypropylene plates were performed using [3H]-SB674042 (Moraveck Corporation, specific activity=35.3 Ci/mmol), diluted to a 10 nM concentration in PBS (4 nM final). Compounds were solubilized in 100% DMSO (Acros Organics, Cat. #61042-1000) and tested over a range of 7 concentrations (from 0.1 nM to 10 uM). The final concentration of DMSO in the reactions is equal to or less than 0.1%. Total and nonspecific binding was determined in the absence and presence of 10 uM almorexant. The total volume of each reaction is 200 uL (20 uL of diluted compounds, 80 uL of [3H]-(1-(5-(2-fluoro-phenyl)-2-methyl-thiazol-4-yl)-1-((S)-2-(5-phenyl-(1,3,4)oxadiazol-2-ylmethyl)-pyrrolidin-1-yl)-methanone) diluted in PBS and 100 uL of the cell suspension). Reactions were run for 60 min at room temperature and terminated by filtration through GF/C filter plates (PerkinElmer, Cat. #6005174) presoaked in 0.3% polyethylenimine using the cell harvester (PerkinElmer Filtermate). The plates were washed 3 times by aspirating 30 ml PBS through the plates. Plates were dried in 55° C. oven for 60 min, scintillation fluid was added, and the radioactivity was counted on a Topcount (Packard).

Plates were dried in 55° C. oven for 60 min, scintillation fluid was added, and the radioactivity was counted on a Topcount (Packard).Radioligand Binding Assay: Human Embryonic Kidney 293 cells (HEK293) stably expressing rat orexin 1 receptor (Genebank accession number NM_001525) or Chinese ovary cells (CHO) stably expressing human orexin 1 receptor (Genebank accession number NM_001526) were grown to confluency in DMEM (Hyclone, cat #SH30022), 10% FBS, 1x Pen/Strep, 1x sodium pyruvate, 10 mM HEPES, 600 ug/mL G418 and DMEM/F12 (Gibco, Cat #11039), 10% FBS, 1x Pen/Strep, 600 ug/mL G418 media, respectively on 150 cm^2 tissue culture plates, washed with 5 mM EDTA in PBS (HyClone Dulbecco's Phosphate Buffered Saline 1x with Calcium and Magnesium, Cat #SH30264.01, hereafter referred to simply as PBS) and scraped into 50 ml tubes. After centrifugation (2KxG, 5 min at 4° C.), the supernatant was aspirated and the pellets frozen and stored at -80\°C. Cells were resuspended in PBS in the presence of 1 tablet of protease inhibitor cocktail (Roche, Cat. #11836145001) per 50 mL. Each cell pellet from a 15 cm plate was resuspended in 10 mL, stored on ice, and homogenized for 45 sec prior to addition to the reactions. Competition binding experiments in 96 well polypropylene plates were performed using [3H]-SB674042 (Moraveck Corporation, specific activity=35.3 Ci/mmol), diluted to a 10 nM concentration in PBS (4 nM final). Compounds were solubilized in 100% DMSO (Acros Organics, Cat. #61042-1000) and tested over a range of 7 concentrations (from 0.1 nM to 10 uM). The final concentration of DMSO in the reactions is equal to or less than 0.1%. Total and nonspecific binding was determined in the absence and presence of 10 uM almorexant. The total volume of each reaction is 200 uL (20 uL of diluted compounds, 80 uL of [3H]-(1-(5-(2-fluoro-phenyl)-2-methyl-thiazol-4-yl)-1-((S)-2-(5-phenyl-(1,3,4)oxadiazol-2-ylmethyl)-pyrrolidin-1-yl)-methanone) diluted in PBS and 100 uL of the cell suspension).

After centrifugation (2KxG, 5 min at 4° C.), the supernatant was aspirated and the pellets frozen and stored at -80\°C. Cells were resuspended in PBS in the presence of 1 tablet of protease inhibitor cocktail (Roche, Cat. #11836145001) per 50 mL. Each cell pellet from a 15 cm plate was resuspended in 10 mL, stored on ice, and homogenized for 45 sec prior to addition to the reactions. Competition binding experiments in 96 well polypropylene plates were performed using [3H]-SB674042 (Moraveck Corporation, specific activity=35.3 Ci/mmol), diluted to a 10 nM concentration in PBS (4 nM final). Compounds were solubilized in 100% DMSO (Acros Organics, Cat. #61042-1000) and tested over a range of 7 concentrations (from 0.1 nM to 10 uM). The final concentration of DMSO in the reactions is equal to or less than 0.1%. Total and nonspecific binding was determined in the absence and presence of 10 uM almorexant. The total volume of each reaction is 200 uL (20 uL of diluted compounds, 80 uL of [3H]-(1-(5-(2-fluoro-phenyl)-2-methyl-thiazol-4-yl)-1-((S)-2-(5-phenyl-(1,3,4)oxadiazol-2-ylmethyl)-pyrrolidin-1-yl)-methanone) diluted in PBS and 100 uL of the cell suspension). Reactions were run for 60 min at room temperature and terminated by filtration through GF/C filter plates (PerkinElmer, Cat. #6005174) presoaked in 0.3% polyethylenimine using the cell harvester (PerkinElmer Filtermate). The plates were washed 3 times by aspirating 30 ml PBS through the plates.

Plates were dried in 55° C. oven for 60 min, scintillation fluid was added, and the radioactivity was counted on a Topcount (Packard).Radioligand Binding Assay: Human Embryonic Kidney 293 cells (HEK293) stably expressing rat orexin 1 receptor (Genebank accession number NM_001525) or Chinese ovary cells (CHO) stably expressing human orexin 1 receptor (Genebank accession number NM_001526) were grown to confluency in DMEM (Hyclone, cat #SH30022), 10% FBS, 1x Pen/Strep, 1x sodium pyruvate, 10 mM HEPES, 600 ug/mL G418 and DMEM/F12 (Gibco, Cat #11039), 10% FBS, 1x Pen/Strep, 600 ug/mL G418 media, respectively on 150 cm^2 tissue culture plates, washed with 5 mM EDTA in PBS (HyClone Dulbecco's Phosphate Buffered Saline 1x with Calcium and Magnesium, Cat #SH30264.01, hereafter referred to simply as PBS) and scraped into 50 ml tubes. After centrifugation (2KxG, 5 min at 4° C.), the supernatant was aspirated and the pellets frozen and stored at -80\°C. Cells were resuspended in PBS in the presence of 1 tablet of protease inhibitor cocktail (Roche, Cat. #11836145001) per 50 mL. Each cell pellet from a 15 cm plate was resuspended in 10 mL, stored on ice, and homogenized for 45 sec prior to addition to the reactions. Competition binding experiments in 96 well polypropylene plates were performed using [3H]-SB674042 (Moraveck Corporation, specific activity=35.3 Ci/mmol), diluted to a 10 nM concentration in PBS (4 nM final). Compounds were solubilized in 100% DMSO (Acros Organics, Cat. #61042-1000) and tested over a range of 7 concentrations (from 0.1 nM to 10 uM). The final concentration of DMSO in the reactions is equal to or less than 0.1%. Total and nonspecific binding was determined in the absence and presence of 10 uM almorexant. The total volume of each reaction is 200 uL (20 uL of diluted compounds, 80 uL of [3H]-(1-(5-(2-fluoro-phenyl)-2-methyl-thiazol-4-yl)-1-((S)-2-(5-phenyl-(1,3,4)oxadiazol-2-ylmethyl)-pyrrolidin-1-yl)-methanone) diluted in PBS and 100 uL of the cell suspension).

After centrifugation (2KxG, 5 min at 4° C.), the supernatant was aspirated and the pellets frozen and stored at -80\°C. Cells were resuspended in PBS in the presence of 1 tablet of protease inhibitor cocktail (Roche, Cat. #11836145001) per 50 mL. Each cell pellet from a 15 cm plate was resuspended in 10 mL, stored on ice, and homogenized for 45 sec prior to addition to the reactions. Competition binding experiments in 96 well polypropylene plates were performed using [3H]-SB674042 (Moraveck Corporation, specific activity=35.3 Ci/mmol), diluted to a 10 nM concentration in PBS (4 nM final). Compounds were solubilized in 100% DMSO (Acros Organics, Cat. #61042-1000) and tested over a range of 7 concentrations (from 0.1 nM to 10 uM). The final concentration of DMSO in the reactions is equal to or less than 0.1%. Total and nonspecific binding was determined in the absence and presence of 10 uM almorexant. The total volume of each reaction is 200 uL (20 uL of diluted compounds, 80 uL of [3H]-(1-(5-(2-fluoro-phenyl)-2-methyl-thiazol-4-yl)-1-((S)-2-(5-phenyl-(1,3,4)oxadiazol-2-ylmethyl)-pyrrolidin-1-yl)-methanone) diluted in PBS and 100 uL of the cell suspension). Reactions were run for 60 min at room temperature and terminated by filtration through GF/C filter plates (PerkinElmer, Cat. #6005174) presoaked in 0.3% polyethylenimine using the cell harvester (PerkinElmer Filtermate). The plates were washed 3 times by aspirating 30 ml PBS through the plates.

The total volume of each reaction is 200 uL (20 uL of diluted compounds, 80 uL of [3H]-(1-(5-(2-fluoro-phenyl)-2-methyl-thiazol-4-yl)-1-((S)-2-(5-phenyl-(1,3,4)oxadiazol-2-ylmethyl)-pyrrolidin-1-yl)-methanone) diluted in PBS and 100 uL of the cell suspension). Reactions were run for 60 min at room temperature and terminated by filtration through GF/C filter plates (PerkinElmer, Cat. #6005174) presoaked in 0.3% polyethylenimine using the cell harvester (PerkinElmer Filtermate). The plates were washed 3 times by aspirating 30 ml PBS through the plates. Plates were dried in 55° C. oven for 60 min, scintillation fluid was added, and the radioactivity was counted on a Topcount (Packard).

Compounds were solubilized in 100% DMSO (Acros Organics, Cat. #61042-1000) and tested over a range of 7 concentrations (from 0.1 nM to 10 uM). The final concentration of DMSO in the reactions is equal to or less than 0.1%. Total and nonspecific binding was determined in the absence and presence of 10 uM almorexant. The total volume of each reaction is 200 uL (20 uL of diluted compounds, 80 uL of [3H]-(1-(5-(2-fluoro-phenyl)-2-methyl-thiazol-4-yl)-1-((S)-2-(5-phenyl-(1,3,4)oxadiazol-2-ylmethyl)-pyrrolidin-1-yl)-methanone) diluted in PBS and 100 uL of the cell suspension). Reactions were run for 60 min at room temperature and terminated by filtration through GF/C filter plates (PerkinElmer, Cat. #6005174) presoaked in 0.3% polyethylenimine using the cell harvester (PerkinElmer Filtermate). The plates were washed 3 times by aspirating 30 ml PBS through the plates. Plates were dried in 55° C. oven for 60 min, scintillation fluid was added, and the radioactivity was counted on a Topcount (Packard).

Each cell pellet from a 15 cm plate was resuspended in 10 mL, stored on ice, and homogenized for 45 sec prior to addition to the reactions. Competition binding experiments in 96 well polypropylene plates were performed using [3H]-SB674042 (Moraveck Corporation, specific activity=35.3 Ci/mmol), diluted to a 10 nM concentration in PBS (4 nM final). Compounds were solubilized in 100% DMSO (Acros Organics, Cat. #61042-1000) and tested over a range of 7 concentrations (from 0.1 nM to 10 uM). The final concentration of DMSO in the reactions is equal to or less than 0.1%. Total and nonspecific binding was determined in the absence and presence of 10 uM almorexant. The total volume of each reaction is 200 uL (20 uL of diluted compounds, 80 uL of [3H]-(1-(5-(2-fluoro-phenyl)-2-methyl-thiazol-4-yl)-1-((S)-2-(5-phenyl-(1,3,4)oxadiazol-2-ylmethyl)-pyrrolidin-1-yl)-methanone) diluted in PBS and 100 uL of the cell suspension). Reactions were run for 60 min at room temperature and terminated by filtration through GF/C filter plates (PerkinElmer, Cat. #6005174) presoaked in 0.3% polyethylenimine using the cell harvester (PerkinElmer Filtermate). The plates were washed 3 times by aspirating 30 ml PBS through the plates. Plates were dried in 55° C. oven for 60 min, scintillation fluid was added, and the radioactivity was counted on a Topcount (Packard).

Radioligand Binding Assay: Human Embryonic Kidney 293 cells (HEK293) stably expressing rat orexin 1 receptor (Genebank accession number NM_001525) or Chinese ovary cells (CHO) stably expressing human orexin 1 receptor (Genebank accession number NM_001526) were grown to confluency in DMEM (Hyclone, cat #SH30022), 10% FBS, 1x Pen/Strep, 1x sodium pyruvate, 10 mM HEPES, 600 ug/mL G418 and DMEM/F12 (Gibco, Cat #11039), 10% FBS, 1x Pen/Strep, 600 ug/mL G418 media, respectively on 150 cm^2 tissue culture plates, washed with 5 mM EDTA in PBS (HyClone Dulbecco's Phosphate Buffered Saline 1x with Calcium and Magnesium, Cat #SH30264.01, hereafter referred to simply as PBS) and scraped into 50 ml tubes. After centrifugation (2KxG, 5 min at 4° C.), the supernatant was aspirated and the pellets frozen and stored at -80\°C. Cells were resuspended in PBS in the presence of 1 tablet of protease inhibitor cocktail (Roche, Cat. #11836145001) per 50 mL. Each cell pellet from a 15 cm plate was resuspended in 10 mL, stored on ice, and homogenized for 45 sec prior to addition to the reactions. Competition binding experiments in 96 well polypropylene plates were performed using [3H]-SB674042 (Moraveck Corporation, specific activity=35.3 Ci/mmol), diluted to a 10 nM concentration in PBS (4 nM final). Compounds were solubilized in 100% DMSO (Acros Organics, Cat. #61042-1000) and tested over a range of 7 concentrations (from 0.1 nM to 10 uM). The final concentration of DMSO in the reactions is equal to or less than 0.1%. Total and nonspecific binding was determined in the absence and presence of 10 uM almorexant. The total volume of each reaction is 200 uL (20 uL of diluted compounds, 80 uL of [3H]-(1-(5-(2-fluoro-phenyl)-2-methyl-thiazol-4-yl)-1-((S)-2-(5-phenyl-(1,3,4)oxadiazol-2-ylmethyl)-pyrrolidin-1-yl)-methanone) diluted in PBS and 100 uL of the cell suspension).

The total volume of each reaction is 200 uL (20 uL of diluted compounds, 80 uL of [3H]-(1-(5-(2-fluoro-phenyl)-2-methyl-thiazol-4-yl)-1-((S)-2-(5-phenyl-(1,3,4)oxadiazol-2-ylmethyl)-pyrrolidin-1-yl)-methanone) diluted in PBS and 100 uL of the cell suspension). Reactions were run for 60 min at room temperature and terminated by filtration through GF/C filter plates (PerkinElmer, Cat. #6005174) presoaked in 0.3% polyethylenimine using the cell harvester (PerkinElmer Filtermate). The plates were washed 3 times by aspirating 30 ml PBS through the plates. Plates were dried in 55° C. oven for 60 min, scintillation fluid was added, and the radioactivity was counted on a Topcount (Packard).

Cells were resuspended in PBS in the presence of 1 tablet of protease inhibitor cocktail (Roche, Cat. #11836145001) per 50 mL. Each cell pellet from a 15 cm plate was resuspended in 10 mL, stored on ice, and homogenized for 45 sec prior to addition to the reactions. Competition binding experiments in 96 well polypropylene plates were performed using [3H]-SB674042 (Moraveck Corporation, specific activity=35.3 Ci/mmol), diluted to a 10 nM concentration in PBS (4 nM final). Compounds were solubilized in 100% DMSO (Acros Organics, Cat. #61042-1000) and tested over a range of 7 concentrations (from 0.1 nM to 10 uM). The final concentration of DMSO in the reactions is equal to or less than 0.1%. Total and nonspecific binding was determined in the absence and presence of 10 uM almorexant. The total volume of each reaction is 200 uL (20 uL of diluted compounds, 80 uL of [3H]-(1-(5-(2-fluoro-phenyl)-2-methyl-thiazol-4-yl)-1-((S)-2-(5-phenyl-(1,3,4)oxadiazol-2-ylmethyl)-pyrrolidin-1-yl)-methanone) diluted in PBS and 100 uL of the cell suspension). Reactions were run for 60 min at room temperature and terminated by filtration through GF/C filter plates (PerkinElmer, Cat. #6005174) presoaked in 0.3% polyethylenimine using the cell harvester (PerkinElmer Filtermate). The plates were washed 3 times by aspirating 30 ml PBS through the plates. Plates were dried in 55° C. oven for 60 min, scintillation fluid was added, and the radioactivity was counted on a Topcount (Packard).

After centrifugation (2KxG, 5 min at 4° C.), the supernatant was aspirated and the pellets frozen and stored at -80\°C. Cells were resuspended in PBS in the presence of 1 tablet of protease inhibitor cocktail (Roche, Cat. #11836145001) per 50 mL. Each cell pellet from a 15 cm plate was resuspended in 10 mL, stored on ice, and homogenized for 45 sec prior to addition to the reactions. Competition binding experiments in 96 well polypropylene plates were performed using [3H]-SB674042 (Moraveck Corporation, specific activity=35.3 Ci/mmol), diluted to a 10 nM concentration in PBS (4 nM final). Compounds were solubilized in 100% DMSO (Acros Organics, Cat. #61042-1000) and tested over a range of 7 concentrations (from 0.1 nM to 10 uM). The final concentration of DMSO in the reactions is equal to or less than 0.1%. Total and nonspecific binding was determined in the absence and presence of 10 uM almorexant. The total volume of each reaction is 200 uL (20 uL of diluted compounds, 80 uL of [3H]-(1-(5-(2-fluoro-phenyl)-2-methyl-thiazol-4-yl)-1-((S)-2-(5-phenyl-(1,3,4)oxadiazol-2-ylmethyl)-pyrrolidin-1-yl)-methanone) diluted in PBS and 100 uL of the cell suspension).

Competition binding experiments in 96 well polypropylene plates were performed using [3H]-SB674042 (Moraveck Corporation, specific activity=35.3 Ci/mmol), diluted to a 10 nM concentration in PBS (4 nM final). Compounds were solubilized in 100% DMSO (Acros Organics, Cat. #61042-1000) and tested over a range of 7 concentrations (from 0.1 nM to 10 uM). The final concentration of DMSO in the reactions is equal to or less than 0.1%. Total and nonspecific binding was determined in the absence and presence of 10 uM almorexant. The total volume of each reaction is 200 uL (20 uL of diluted compounds, 80 uL of [3H]-(1-(5-(2-fluoro-phenyl)-2-methyl-thiazol-4-yl)-1-((S)-2-(5-phenyl-(1,3,4)oxadiazol-2-ylmethyl)-pyrrolidin-1-yl)-methanone) diluted in PBS and 100 uL of the cell suspension). Reactions were run for 60 min at room temperature and terminated by filtration through GF/C filter plates (PerkinElmer, Cat. #6005174) presoaked in 0.3% polyethylenimine using the cell harvester (PerkinElmer Filtermate). The plates were washed 3 times by aspirating 30 ml PBS through the plates. Plates were dried in 55° C. oven for 60 min, scintillation fluid was added, and the radioactivity was counted on a Topcount (Packard).

Radioligand Binding Assay: Human Embryonic Kidney 293 cells (HEK293) stably expressing rat orexin 1 receptor (Genebank accession number NM_001525) or Chinese ovary cells (CHO) stably expressing human orexin 1 receptor (Genebank accession number NM_001526) were grown to confluency in DMEM (Hyclone, cat #SH30022), 10% FBS, 1x Pen/Strep, 1x sodium pyruvate, 10 mM HEPES, 600 ug/mL G418 and DMEM/F12 (Gibco, Cat #11039), 10% FBS, 1x Pen/Strep, 600 ug/mL G418 media, respectively on 150 cm^2 tissue culture plates, washed with 5 mM EDTA in PBS (HyClone Dulbecco's Phosphate Buffered Saline 1x with Calcium and Magnesium, Cat #SH30264.01, hereafter referred to simply as PBS) and scraped into 50 ml tubes. After centrifugation (2KxG, 5 min at 4° C.), the supernatant was aspirated and the pellets frozen and stored at -80\°C. Cells were resuspended in PBS in the presence of 1 tablet of protease inhibitor cocktail (Roche, Cat. #11836145001) per 50 mL. Each cell pellet from a 15 cm plate was resuspended in 10 mL, stored on ice, and homogenized for 45 sec prior to addition to the reactions. Competition binding experiments in 96 well polypropylene plates were performed using [3H]-SB674042 (Moraveck Corporation, specific activity=35.3 Ci/mmol), diluted to a 10 nM concentration in PBS (4 nM final). Compounds were solubilized in 100% DMSO (Acros Organics, Cat. #61042-1000) and tested over a range of 7 concentrations (from 0.1 nM to 10 uM). The final concentration of DMSO in the reactions is equal to or less than 0.1%. Total and nonspecific binding was determined in the absence and presence of 10 uM almorexant. The total volume of each reaction is 200 uL (20 uL of diluted compounds, 80 uL of [3H]-(1-(5-(2-fluoro-phenyl)-2-methyl-thiazol-4-yl)-1-((S)-2-(5-phenyl-(1,3,4)oxadiazol-2-ylmethyl)-pyrrolidin-1-yl)-methanone) diluted in PBS and 100 uL of the cell suspension). Reactions were run for 60 min at room temperature and terminated by filtration through GF/C filter plates (PerkinElmer, Cat. #6005174) presoaked in 0.3% polyethylenimine using the cell harvester (PerkinElmer Filtermate). The plates were washed 3 times by aspirating 30 ml PBS through the plates. Plates were dried in 55° C. oven for 60 min, scintillation fluid was added, and the radioactivity was counted on a Topcount (Packard).Radioligand Binding Assay: Human Embryonic Kidney 293 cells (HEK293) stably expressing rat orexin 1 receptor (Genebank accession number NM_001525) or Chinese ovary cells (CHO) stably expressing human orexin 1 receptor (Genebank accession number NM_001526) were grown to confluency in DMEM (Hyclone, cat #SH30022), 10% FBS, 1x Pen/Strep, 1x sodium pyruvate, 10 mM HEPES, 600 ug/mL G418 and DMEM/F12 (Gibco, Cat #11039), 10% FBS, 1x Pen/Strep, 600 ug/mL G418 media, respectively on 150 cm^2 tissue culture plates, washed with 5 mM EDTA in PBS (HyClone Dulbecco's Phosphate Buffered Saline 1x with Calcium and Magnesium, Cat #SH30264.01, hereafter referred to simply as PBS) and scraped into 50 ml tubes.

After centrifugation (2KxG, 5 min at 4° C.), the supernatant was aspirated and the pellets frozen and stored at -80\°C. Cells were resuspended in PBS in the presence of 1 tablet of protease inhibitor cocktail (Roche, Cat. #11836145001) per 50 mL. Each cell pellet from a 15 cm plate was resuspended in 10 mL, stored on ice, and homogenized for 45 sec prior to addition to the reactions. Competition binding experiments in 96 well polypropylene plates were performed using [3H]-SB674042 (Moraveck Corporation, specific activity=35.3 Ci/mmol), diluted to a 10 nM concentration in PBS (4 nM final). Compounds were solubilized in 100% DMSO (Acros Organics, Cat. #61042-1000) and tested over a range of 7 concentrations (from 0.1 nM to 10 uM). The final concentration of DMSO in the reactions is equal to or less than 0.1%. Total and nonspecific binding was determined in the absence and presence of 10 uM almorexant. The total volume of each reaction is 200 uL (20 uL of diluted compounds, 80 uL of [3H]-(1-(5-(2-fluoro-phenyl)-2-methyl-thiazol-4-yl)-1-((S)-2-(5-phenyl-(1,3,4)oxadiazol-2-ylmethyl)-pyrrolidin-1-yl)-methanone) diluted in PBS and 100 uL of the cell suspension).

Cells were resuspended in PBS in the presence of 1 tablet of protease inhibitor cocktail (Roche, Cat. #11836145001) per 50 mL. Each cell pellet from a 15 cm plate was resuspended in 10 mL, stored on ice, and homogenized for 45 sec prior to addition to the reactions. Competition binding experiments in 96 well polypropylene plates were performed using [3H]-SB674042 (Moraveck Corporation, specific activity=35.3 Ci/mmol), diluted to a 10 nM concentration in PBS (4 nM final). Compounds were solubilized in 100% DMSO (Acros Organics, Cat. #61042-1000) and tested over a range of 7 concentrations (from 0.1 nM to 10 uM). The final concentration of DMSO in the reactions is equal to or less than 0.1%. Total and nonspecific binding was determined in the absence and presence of 10 uM almorexant. The total volume of each reaction is 200 uL (20 uL of diluted compounds, 80 uL of [3H]-(1-(5-(2-fluoro-phenyl)-2-methyl-thiazol-4-yl)-1-((S)-2-(5-phenyl-(1,3,4)oxadiazol-2-ylmethyl)-pyrrolidin-1-yl)-methanone) diluted in PBS and 100 uL of the cell suspension). Reactions were run for 60 min at room temperature and terminated by filtration through GF/C filter plates (PerkinElmer, Cat. #6005174) presoaked in 0.3% polyethylenimine using the cell harvester (PerkinElmer Filtermate). The plates were washed 3 times by aspirating 30 ml PBS through the plates.

Radioligand Binding Assay: Human Embryonic Kidney 293 cells (HEK293) stably expressing rat orexin 1 receptor (Genebank accession number NM_001525) or Chinese ovary cells (CHO) stably expressing human orexin 1 receptor (Genebank accession number NM_001526) were grown to confluency in DMEM (Hyclone, cat #SH30022), 10% FBS, 1x Pen/Strep, 1x sodium pyruvate, 10 mM HEPES, 600 ug/mL G418 and DMEM/F12 (Gibco, Cat #11039), 10% FBS, 1x Pen/Strep, 600 ug/mL G418 media, respectively on 150 cm^2 tissue culture plates, washed with 5 mM EDTA in PBS (HyClone Dulbecco's Phosphate Buffered Saline 1x with Calcium and Magnesium, Cat #SH30264.01, hereafter referred to simply as PBS) and scraped into 50 ml tubes. After centrifugation (2KxG, 5 min at 4° C.), the supernatant was aspirated and the pellets frozen and stored at -80\°C. Cells were resuspended in PBS in the presence of 1 tablet of protease inhibitor cocktail (Roche, Cat. #11836145001) per 50 mL. Each cell pellet from a 15 cm plate was resuspended in 10 mL, stored on ice, and homogenized for 45 sec prior to addition to the reactions. Competition binding experiments in 96 well polypropylene plates were performed using [3H]-SB674042 (Moraveck Corporation, specific activity=35.3 Ci/mmol), diluted to a 10 nM concentration in PBS (4 nM final). Compounds were solubilized in 100% DMSO (Acros Organics, Cat. #61042-1000) and tested over a range of 7 concentrations (from 0.1 nM to 10 uM). The final concentration of DMSO in the reactions is equal to or less than 0.1%. Total and nonspecific binding was determined in the absence and presence of 10 uM almorexant. The total volume of each reaction is 200 uL (20 uL of diluted compounds, 80 uL of [3H]-(1-(5-(2-fluoro-phenyl)-2-methyl-thiazol-4-yl)-1-((S)-2-(5-phenyl-(1,3,4)oxadiazol-2-ylmethyl)-pyrrolidin-1-yl)-methanone) diluted in PBS and 100 uL of the cell suspension). Reactions were run for 60 min at room temperature and terminated by filtration through GF/C filter plates (PerkinElmer, Cat. #6005174) presoaked in 0.3% polyethylenimine using the cell harvester (PerkinElmer Filtermate). The plates were washed 3 times by aspirating 30 ml PBS through the plates. Plates were dried in 55° C. oven for 60 min, scintillation fluid was added, and the radioactivity was counted on a Topcount (Packard).Radioligand Binding Assay: Human Embryonic Kidney 293 cells (HEK293) stably expressing rat orexin 1 receptor (Genebank accession number NM_001525) or Chinese ovary cells (CHO) stably expressing human orexin 1 receptor (Genebank accession number NM_001526) were grown to confluency in DMEM (Hyclone, cat #SH30022), 10% FBS, 1x Pen/Strep, 1x sodium pyruvate, 10 mM HEPES, 600 ug/mL G418 and DMEM/F12 (Gibco, Cat #11039), 10% FBS, 1x Pen/Strep, 600 ug/mL G418 media, respectively on 150 cm^2 tissue culture plates, washed with 5 mM EDTA in PBS (HyClone Dulbecco's Phosphate Buffered Saline 1x with Calcium and Magnesium, Cat #SH30264.01, hereafter referred to simply as PBS) and scraped into 50 ml tubes.

Radioligand Binding Assay: Human Embryonic Kidney 293 cells (HEK293) stably expressing rat orexin 1 receptor (Genebank accession number NM_001525) or Chinese ovary cells (CHO) stably expressing human orexin 1 receptor (Genebank accession number NM_001526) were grown to confluency in DMEM (Hyclone, cat #SH30022), 10% FBS, 1x Pen/Strep, 1x sodium pyruvate, 10 mM HEPES, 600 ug/mL G418 and DMEM/F12 (Gibco, Cat #11039), 10% FBS, 1x Pen/Strep, 600 ug/mL G418 media, respectively on 150 cm^2 tissue culture plates, washed with 5 mM EDTA in PBS (HyClone Dulbecco's Phosphate Buffered Saline 1x with Calcium and Magnesium, Cat #SH30264.01, hereafter referred to simply as PBS) and scraped into 50 ml tubes. After centrifugation (2KxG, 5 min at 4° C.), the supernatant was aspirated and the pellets frozen and stored at -80\°C. Cells were resuspended in PBS in the presence of 1 tablet of protease inhibitor cocktail (Roche, Cat. #11836145001) per 50 mL. Each cell pellet from a 15 cm plate was resuspended in 10 mL, stored on ice, and homogenized for 45 sec prior to addition to the reactions. Competition binding experiments in 96 well polypropylene plates were performed using [3H]-SB674042 (Moraveck Corporation, specific activity=35.3 Ci/mmol), diluted to a 10 nM concentration in PBS (4 nM final). Compounds were solubilized in 100% DMSO (Acros Organics, Cat. #61042-1000) and tested over a range of 7 concentrations (from 0.1 nM to 10 uM). The final concentration of DMSO in the reactions is equal to or less than 0.1%. Total and nonspecific binding was determined in the absence and presence of 10 uM almorexant. The total volume of each reaction is 200 uL (20 uL of diluted compounds, 80 uL of [3H]-(1-(5-(2-fluoro-phenyl)-2-methyl-thiazol-4-yl)-1-((S)-2-(5-phenyl-(1,3,4)oxadiazol-2-ylmethyl)-pyrrolidin-1-yl)-methanone) diluted in PBS and 100 uL of the cell suspension).

Plates were dried in 55° C. oven for 60 min, scintillation fluid was added, and the radioactivity was counted on a Topcount (Packard).Radioligand Binding Assay: Human Embryonic Kidney 293 cells (HEK293) stably expressing rat orexin 1 receptor (Genebank accession number NM_001525) or Chinese ovary cells (CHO) stably expressing human orexin 1 receptor (Genebank accession number NM_001526) were grown to confluency in DMEM (Hyclone, cat #SH30022), 10% FBS, 1x Pen/Strep, 1x sodium pyruvate, 10 mM HEPES, 600 ug/mL G418 and DMEM/F12 (Gibco, Cat #11039), 10% FBS, 1x Pen/Strep, 600 ug/mL G418 media, respectively on 150 cm^2 tissue culture plates, washed with 5 mM EDTA in PBS (HyClone Dulbecco's Phosphate Buffered Saline 1x with Calcium and Magnesium, Cat #SH30264.01, hereafter referred to simply as PBS) and scraped into 50 ml tubes. After centrifugation (2KxG, 5 min at 4° C.), the supernatant was aspirated and the pellets frozen and stored at -80\°C. Cells were resuspended in PBS in the presence of 1 tablet of protease inhibitor cocktail (Roche, Cat. #11836145001) per 50 mL. Each cell pellet from a 15 cm plate was resuspended in 10 mL, stored on ice, and homogenized for 45 sec prior to addition to the reactions. Competition binding experiments in 96 well polypropylene plates were performed using [3H]-SB674042 (Moraveck Corporation, specific activity=35.3 Ci/mmol), diluted to a 10 nM concentration in PBS (4 nM final). Compounds were solubilized in 100% DMSO (Acros Organics, Cat. #61042-1000) and tested over a range of 7 concentrations (from 0.1 nM to 10 uM). The final concentration of DMSO in the reactions is equal to or less than 0.1%. Total and nonspecific binding was determined in the absence and presence of 10 uM almorexant. The total volume of each reaction is 200 uL (20 uL of diluted compounds, 80 uL of [3H]-(1-(5-(2-fluoro-phenyl)-2-methyl-thiazol-4-yl)-1-((S)-2-(5-phenyl-(1,3,4)oxadiazol-2-ylmethyl)-pyrrolidin-1-yl)-methanone) diluted in PBS and 100 uL of the cell suspension).

Radioligand Binding Assay: Human Embryonic Kidney 293 cells (HEK293) stably expressing rat orexin 1 receptor (Genebank accession number NM_001525) or Chinese ovary cells (CHO) stably expressing human orexin 1 receptor (Genebank accession number NM_001526) were grown to confluency in DMEM (Hyclone, cat #SH30022), 10% FBS, 1x Pen/Strep, 1x sodium pyruvate, 10 mM HEPES, 600 ug/mL G418 and DMEM/F12 (Gibco, Cat #11039), 10% FBS, 1x Pen/Strep, 600 ug/mL G418 media, respectively on 150 cm^2 tissue culture plates, washed with 5 mM EDTA in PBS (HyClone Dulbecco's Phosphate Buffered Saline 1x with Calcium and Magnesium, Cat #SH30264.01, hereafter referred to simply as PBS) and scraped into 50 ml tubes. After centrifugation (2KxG, 5 min at 4° C.), the supernatant was aspirated and the pellets frozen and stored at -80\°C. Cells were resuspended in PBS in the presence of 1 tablet of protease inhibitor cocktail (Roche, Cat. #11836145001) per 50 mL. Each cell pellet from a 15 cm plate was resuspended in 10 mL, stored on ice, and homogenized for 45 sec prior to addition to the reactions. Competition binding experiments in 96 well polypropylene plates were performed using [3H]-SB674042 (Moraveck Corporation, specific activity=35.3 Ci/mmol), diluted to a 10 nM concentration in PBS (4 nM final). Compounds were solubilized in 100% DMSO (Acros Organics, Cat. #61042-1000) and tested over a range of 7 concentrations (from 0.1 nM to 10 uM). The final concentration of DMSO in the reactions is equal to or less than 0.1%. Total and nonspecific binding was determined in the absence and presence of 10 uM almorexant. The total volume of each reaction is 200 uL (20 uL of diluted compounds, 80 uL of [3H]-(1-(5-(2-fluoro-phenyl)-2-methyl-thiazol-4-yl)-1-((S)-2-(5-phenyl-(1,3,4)oxadiazol-2-ylmethyl)-pyrrolidin-1-yl)-methanone) diluted in PBS and 100 uL of the cell suspension). Reactions were run for 60 min at room temperature and terminated by filtration through GF/C filter plates (PerkinElmer, Cat. #6005174) presoaked in 0.3% polyethylenimine using the cell harvester (PerkinElmer Filtermate). The plates were washed 3 times by aspirating 30 ml PBS through the plates. Plates were dried in 55° C. oven for 60 min, scintillation fluid was added, and the radioactivity was counted on a Topcount (Packard).Radioligand Binding Assay: Human Embryonic Kidney 293 cells (HEK293) stably expressing rat orexin 1 receptor (Genebank accession number NM_001525) or Chinese ovary cells (CHO) stably expressing human orexin 1 receptor (Genebank accession number NM_001526) were grown to confluency in DMEM (Hyclone, cat #SH30022), 10% FBS, 1x Pen/Strep, 1x sodium pyruvate, 10 mM HEPES, 600 ug/mL G418 and DMEM/F12 (Gibco, Cat #11039), 10% FBS, 1x Pen/Strep, 600 ug/mL G418 media, respectively on 150 cm^2 tissue culture plates, washed with 5 mM EDTA in PBS (HyClone Dulbecco's Phosphate Buffered Saline 1x with Calcium and Magnesium, Cat #SH30264.01, hereafter referred to simply as PBS) and scraped into 50 ml tubes.

The final concentration of DMSO in the reactions is equal to or less than 0.1%. Total and nonspecific binding was determined in the absence and presence of 10 uM almorexant. The total volume of each reaction is 200 uL (20 uL of diluted compounds, 80 uL of [3H]-(1-(5-(2-fluoro-phenyl)-2-methyl-thiazol-4-yl)-1-((S)-2-(5-phenyl-(1,3,4)oxadiazol-2-ylmethyl)-pyrrolidin-1-yl)-methanone) diluted in PBS and 100 uL of the cell suspension). Reactions were run for 60 min at room temperature and terminated by filtration through GF/C filter plates (PerkinElmer, Cat. #6005174) presoaked in 0.3% polyethylenimine using the cell harvester (PerkinElmer Filtermate). The plates were washed 3 times by aspirating 30 ml PBS through the plates.

After centrifugation (2KxG, 5 min at 4° C.), the supernatant was aspirated and the pellets frozen and stored at -80\°C. Cells were resuspended in PBS in the presence of 1 tablet of protease inhibitor cocktail (Roche, Cat. #11836145001) per 50 mL. Each cell pellet from a 15 cm plate was resuspended in 10 mL, stored on ice, and homogenized for 45 sec prior to addition to the reactions. Competition binding experiments in 96 well polypropylene plates were performed using [3H]-SB674042 (Moraveck Corporation, specific activity=35.3 Ci/mmol), diluted to a 10 nM concentration in PBS (4 nM final). Compounds were solubilized in 100% DMSO (Acros Organics, Cat. #61042-1000) and tested over a range of 7 concentrations (from 0.1 nM to 10 uM). The final concentration of DMSO in the reactions is equal to or less than 0.1%. Total and nonspecific binding was determined in the absence and presence of 10 uM almorexant.

After centrifugation (2KxG, 5 min at 4° C.), the supernatant was aspirated and the pellets frozen and stored at -80\°C. Cells were resuspended in PBS in the presence of 1 tablet of protease inhibitor cocktail (Roche, Cat. #11836145001) per 50 mL. Each cell pellet from a 15 cm plate was resuspended in 10 mL, stored on ice, and homogenized for 45 sec prior to addition to the reactions. Competition binding experiments in 96 well polypropylene plates were performed using [3H]-SB674042 (Moraveck Corporation, specific activity=35.3 Ci/mmol), diluted to a 10 nM concentration in PBS (4 nM final). Compounds were solubilized in 100% DMSO (Acros Organics, Cat. #61042-1000) and tested over a range of 7 concentrations (from 0.1 nM to 10 uM). The final concentration of DMSO in the reactions is equal to or less than 0.1%. Total and nonspecific binding was determined in the absence and presence of 10 uM almorexant.

After centrifugation (2KxG, 5 min at 4° C.), the supernatant was aspirated and the pellets frozen and stored at -80\°C. Cells were resuspended in PBS in the presence of 1 tablet of protease inhibitor cocktail (Roche, Cat. #11836145001) per 50 mL. Each cell pellet from a 15 cm plate was resuspended in 10 mL, stored on ice, and homogenized for 45 sec prior to addition to the reactions. Competition binding experiments in 96 well polypropylene plates were performed using [3H]-SB674042 (Moraveck Corporation, specific activity=35.3 Ci/mmol), diluted to a 10 nM concentration in PBS (4 nM final). Compounds were solubilized in 100% DMSO (Acros Organics, Cat. #61042-1000) and tested over a range of 7 concentrations (from 0.1 nM to 10 uM). The final concentration of DMSO in the reactions is equal to or less than 0.1%. Total and nonspecific binding was determined in the absence and presence of 10 uM almorexant. The total volume of each reaction is 200 uL (20 uL of diluted compounds, 80 uL of [3H]-(1-(5-(2-fluoro-phenyl)-2-methyl-thiazol-4-yl)-1-((S)-2-(5-phenyl-(1,3,4)oxadiazol-2-ylmethyl)-pyrrolidin-1-yl)-methanone) diluted in PBS and 100 uL of the cell suspension). Reactions were run for 60 min at room temperature and terminated by filtration through GF/C filter plates (PerkinElmer, Cat. #6005174) presoaked in 0.3% polyethylenimine using the cell harvester (PerkinElmer Filtermate). The plates were washed 3 times by aspirating 30 ml PBS through the plates.

Competition binding experiments in 96 well polypropylene plates were performed using [3H]-SB674042 (Moraveck Corporation, specific activity=35.3 Ci/mmol), diluted to a 10 nM concentration in PBS (4 nM final). Compounds were solubilized in 100% DMSO (Acros Organics, Cat. #61042-1000) and tested over a range of 7 concentrations (from 0.1 nM to 10 uM). The final concentration of DMSO in the reactions is equal to or less than 0.1%. Total and nonspecific binding was determined in the absence and presence of 10 uM almorexant. The total volume of each reaction is 200 uL (20 uL of diluted compounds, 80 uL of [3H]-(1-(5-(2-fluoro-phenyl)-2-methyl-thiazol-4-yl)-1-((S)-2-(5-phenyl-(1,3,4)oxadiazol-2-ylmethyl)-pyrrolidin-1-yl)-methanone) diluted in PBS and 100 uL of the cell suspension). Reactions were run for 60 min at room temperature and terminated by filtration through GF/C filter plates (PerkinElmer, Cat. #6005174) presoaked in 0.3% polyethylenimine using the cell harvester (PerkinElmer Filtermate). The plates were washed 3 times by aspirating 30 ml PBS through the plates. Plates were dried in 55° C. oven for 60 min, scintillation fluid was added, and the radioactivity was counted on a Topcount (Packard).

The final concentration of DMSO in the reactions is equal to or less than 0.1%. Total and nonspecific binding was determined in the absence and presence of 10 uM almorexant. The total volume of each reaction is 200 uL (20 uL of diluted compounds, 80 uL of [3H]-(1-(5-(2-fluoro-phenyl)-2-methyl-thiazol-4-yl)-1-((S)-2-(5-phenyl-(1,3,4)oxadiazol-2-ylmethyl)-pyrrolidin-1-yl)-methanone) diluted in PBS and 100 uL of the cell suspension). Reactions were run for 60 min at room temperature and terminated by filtration through GF/C filter plates (PerkinElmer, Cat. #6005174) presoaked in 0.3% polyethylenimine using the cell harvester (PerkinElmer Filtermate). The plates were washed 3 times by aspirating 30 ml PBS through the plates. Plates were dried in 55° C. oven for 60 min, scintillation fluid was added, and the radioactivity was counted on a Topcount (Packard).

Radioligand Binding Assay: Human Embryonic Kidney 293 cells (HEK293) stably expressing rat orexin 1 receptor (Genebank accession number NM_001525) or Chinese ovary cells (CHO) stably expressing human orexin 1 receptor (Genebank accession number NM_001526) were grown to confluency in DMEM (Hyclone, cat #SH30022), 10% FBS, 1x Pen/Strep, 1x sodium pyruvate, 10 mM HEPES, 600 ug/mL G418 and DMEM/F12 (Gibco, Cat #11039), 10% FBS, 1x Pen/Strep, 600 ug/mL G418 media, respectively on 150 cm^2 tissue culture plates, washed with 5 mM EDTA in PBS (HyClone Dulbecco's Phosphate Buffered Saline 1x with Calcium and Magnesium, Cat #SH30264.01, hereafter referred to simply as PBS) and scraped into 50 ml tubes. After centrifugation (2KxG, 5 min at 4° C.), the supernatant was aspirated and the pellets frozen and stored at -80\°C. Cells were resuspended in PBS in the presence of 1 tablet of protease inhibitor cocktail (Roche, Cat. #11836145001) per 50 mL. Each cell pellet from a 15 cm plate was resuspended in 10 mL, stored on ice, and homogenized for 45 sec prior to addition to the reactions. Competition binding experiments in 96 well polypropylene plates were performed using [3H]-SB674042 (Moraveck Corporation, specific activity=35.3 Ci/mmol), diluted to a 10 nM concentration in PBS (4 nM final). Compounds were solubilized in 100% DMSO (Acros Organics, Cat. #61042-1000) and tested over a range of 7 concentrations (from 0.1 nM to 10 uM). The final concentration of DMSO in the reactions is equal to or less than 0.1%. Total and nonspecific binding was determined in the absence and presence of 10 uM almorexant. The total volume of each reaction is 200 uL (20 uL of diluted compounds, 80 uL of [3H]-(1-(5-(2-fluoro-phenyl)-2-methyl-thiazol-4-yl)-1-((S)-2-(5-phenyl-(1,3,4)oxadiazol-2-ylmethyl)-pyrrolidin-1-yl)-methanone) diluted in PBS and 100 uL of the cell suspension).

Radioligand Binding Assay: Human Embryonic Kidney 293 cells (HEK293) stably expressing rat orexin 1 receptor (Genebank accession number NM_001525) or Chinese ovary cells (CHO) stably expressing human orexin 1 receptor (Genebank accession number NM_001526) were grown to confluency in DMEM (Hyclone, cat #SH30022), 10% FBS, 1x Pen/Strep, 1x sodium pyruvate, 10 mM HEPES, 600 ug/mL G418 and DMEM/F12 (Gibco, Cat #11039), 10% FBS, 1x Pen/Strep, 600 ug/mL G418 media, respectively on 150 cm^2 tissue culture plates, washed with 5 mM EDTA in PBS (HyClone Dulbecco's Phosphate Buffered Saline 1x with Calcium and Magnesium, Cat #SH30264.01, hereafter referred to simply as PBS) and scraped into 50 ml tubes. After centrifugation (2KxG, 5 min at 4° C.), the supernatant was aspirated and the pellets frozen and stored at -80\°C. Cells were resuspended in PBS in the presence of 1 tablet of protease inhibitor cocktail (Roche, Cat. #11836145001) per 50 mL. Each cell pellet from a 15 cm plate was resuspended in 10 mL, stored on ice, and homogenized for 45 sec prior to addition to the reactions. Competition binding experiments in 96 well polypropylene plates were performed using [3H]-SB674042 (Moraveck Corporation, specific activity=35.3 Ci/mmol), diluted to a 10 nM concentration in PBS (4 nM final). Compounds were solubilized in 100% DMSO (Acros Organics, Cat. #61042-1000) and tested over a range of 7 concentrations (from 0.1 nM to 10 uM). The final concentration of DMSO in the reactions is equal to or less than 0.1%. Total and nonspecific binding was determined in the absence and presence of 10 uM almorexant. The total volume of each reaction is 200 uL (20 uL of diluted compounds, 80 uL of [3H]-(1-(5-(2-fluoro-phenyl)-2-methyl-thiazol-4-yl)-1-((S)-2-(5-phenyl-(1,3,4)oxadiazol-2-ylmethyl)-pyrrolidin-1-yl)-methanone) diluted in PBS and 100 uL of the cell suspension). Reactions were run for 60 min at room temperature and terminated by filtration through GF/C filter plates (PerkinElmer, Cat. #6005174) presoaked in 0.3% polyethylenimine using the cell harvester (PerkinElmer Filtermate). The plates were washed 3 times by aspirating 30 ml PBS through the plates. Plates were dried in 55° C. oven for 60 min, scintillation fluid was added, and the radioactivity was counted on a Topcount (Packard).Radioligand Binding Assay: Human Embryonic Kidney 293 cells (HEK293) stably expressing rat orexin 1 receptor (Genebank accession number NM_001525) or Chinese ovary cells (CHO) stably expressing human orexin 1 receptor (Genebank accession number NM_001526) were grown to confluency in DMEM (Hyclone, cat #SH30022), 10% FBS, 1x Pen/Strep, 1x sodium pyruvate, 10 mM HEPES, 600 ug/mL G418 and DMEM/F12 (Gibco, Cat #11039), 10% FBS, 1x Pen/Strep, 600 ug/mL G418 media, respectively on 150 cm^2 tissue culture plates, washed with 5 mM EDTA in PBS (HyClone Dulbecco's Phosphate Buffered Saline 1x with Calcium and Magnesium, Cat #SH30264.01, hereafter referred to simply as PBS) and scraped into 50 ml tubes.

After centrifugation (2KxG, 5 min at 4° C.), the supernatant was aspirated and the pellets frozen and stored at -80\°C. Cells were resuspended in PBS in the presence of 1 tablet of protease inhibitor cocktail (Roche, Cat. #11836145001) per 50 mL. Each cell pellet from a 15 cm plate was resuspended in 10 mL, stored on ice, and homogenized for 45 sec prior to addition to the reactions. Competition binding experiments in 96 well polypropylene plates were performed using [3H]-SB674042 (Moraveck Corporation, specific activity=35.3 Ci/mmol), diluted to a 10 nM concentration in PBS (4 nM final). Compounds were solubilized in 100% DMSO (Acros Organics, Cat. #61042-1000) and tested over a range of 7 concentrations (from 0.1 nM to 10 uM). The final concentration of DMSO in the reactions is equal to or less than 0.1%. Total and nonspecific binding was determined in the absence and presence of 10 uM almorexant. The total volume of each reaction is 200 uL (20 uL of diluted compounds, 80 uL of [3H]-(1-(5-(2-fluoro-phenyl)-2-methyl-thiazol-4-yl)-1-((S)-2-(5-phenyl-(1,3,4)oxadiazol-2-ylmethyl)-pyrrolidin-1-yl)-methanone) diluted in PBS and 100 uL of the cell suspension). Reactions were run for 60 min at room temperature and terminated by filtration through GF/C filter plates (PerkinElmer, Cat. #6005174) presoaked in 0.3% polyethylenimine using the cell harvester (PerkinElmer Filtermate). The plates were washed 3 times by aspirating 30 ml PBS through the plates. Plates were dried in 55° C. oven for 60 min, scintillation fluid was added, and the radioactivity was counted on a Topcount (Packard).Radioligand Binding Assay: Human Embryonic Kidney 293 cells (HEK293) stably expressing rat orexin 1 receptor (Genebank accession number NM_001525) or Chinese ovary cells (CHO) stably expressing human orexin 1 receptor (Genebank accession number NM_001526) were grown to confluency in DMEM (Hyclone, cat #SH30022), 10% FBS, 1x Pen/Strep, 1x sodium pyruvate, 10 mM HEPES, 600 ug/mL G418 and DMEM/F12 (Gibco, Cat #11039), 10% FBS, 1x Pen/Strep, 600 ug/mL G418 media, respectively on 150 cm^2 tissue culture plates, washed with 5 mM EDTA in PBS (HyClone Dulbecco's Phosphate Buffered Saline 1x with Calcium and Magnesium, Cat #SH30264.01, hereafter referred to simply as PBS) and scraped into 50 ml tubes.

Radioligand Binding Assay: Human Embryonic Kidney 293 cells (HEK293) stably expressing rat orexin 1 receptor (Genebank accession number NM_001525) or Chinese ovary cells (CHO) stably expressing human orexin 1 receptor (Genebank accession number NM_001526) were grown to confluency in DMEM (Hyclone, cat #SH30022), 10% FBS, 1x Pen/Strep, 1x sodium pyruvate, 10 mM HEPES, 600 ug/mL G418 and DMEM/F12 (Gibco, Cat #11039), 10% FBS, 1x Pen/Strep, 600 ug/mL G418 media, respectively on 150 cm^2 tissue culture plates, washed with 5 mM EDTA in PBS (HyClone Dulbecco's Phosphate Buffered Saline 1x with Calcium and Magnesium, Cat #SH30264.01, hereafter referred to simply as PBS) and scraped into 50 ml tubes. After centrifugation (2KxG, 5 min at 4° C.), the supernatant was aspirated and the pellets frozen and stored at -80\°C. Cells were resuspended in PBS in the presence of 1 tablet of protease inhibitor cocktail (Roche, Cat. #11836145001) per 50 mL. Each cell pellet from a 15 cm plate was resuspended in 10 mL, stored on ice, and homogenized for 45 sec prior to addition to the reactions. Competition binding experiments in 96 well polypropylene plates were performed using [3H]-SB674042 (Moraveck Corporation, specific activity=35.3 Ci/mmol), diluted to a 10 nM concentration in PBS (4 nM final). Compounds were solubilized in 100% DMSO (Acros Organics, Cat. #61042-1000) and tested over a range of 7 concentrations (from 0.1 nM to 10 uM). The final concentration of DMSO in the reactions is equal to or less than 0.1%. Total and nonspecific binding was determined in the absence and presence of 10 uM almorexant. The total volume of each reaction is 200 uL (20 uL of diluted compounds, 80 uL of [3H]-(1-(5-(2-fluoro-phenyl)-2-methyl-thiazol-4-yl)-1-((S)-2-(5-phenyl-(1,3,4)oxadiazol-2-ylmethyl)-pyrrolidin-1-yl)-methanone) diluted in PBS and 100 uL of the cell suspension). Reactions were run for 60 min at room temperature and terminated by filtration through GF/C filter plates (PerkinElmer, Cat. #6005174) presoaked in 0.3% polyethylenimine using the cell harvester (PerkinElmer Filtermate). The plates were washed 3 times by aspirating 30 ml PBS through the plates. Plates were dried in 55° C. oven for 60 min, scintillation fluid was added, and the radioactivity was counted on a Topcount (Packard).Radioligand Binding Assay: Human Embryonic Kidney 293 cells (HEK293) stably expressing rat orexin 1 receptor (Genebank accession number NM_001525) or Chinese ovary cells (CHO) stably expressing human orexin 1 receptor (Genebank accession number NM_001526) were grown to confluency in DMEM (Hyclone, cat #SH30022), 10% FBS, 1x Pen/Strep, 1x sodium pyruvate, 10 mM HEPES, 600 ug/mL G418 and DMEM/F12 (Gibco, Cat #11039), 10% FBS, 1x Pen/Strep, 600 ug/mL G418 media, respectively on 150 cm^2 tissue culture plates, washed with 5 mM EDTA in PBS (HyClone Dulbecco's Phosphate Buffered Saline 1x with Calcium and Magnesium, Cat #SH30264.01, hereafter referred to simply as PBS) and scraped into 50 ml tubes.

Radioligand Binding Assay: Human Embryonic Kidney 293 cells (HEK293) stably expressing rat orexin 1 receptor (Genebank accession number NM_001525) or Chinese ovary cells (CHO) stably expressing human orexin 1 receptor (Genebank accession number NM_001526) were grown to confluency in DMEM (Hyclone, cat #SH30022), 10% FBS, 1x Pen/Strep, 1x sodium pyruvate, 10 mM HEPES, 600 ug/mL G418 and DMEM/F12 (Gibco, Cat #11039), 10% FBS, 1x Pen/Strep, 600 ug/mL G418 media, respectively on 150 cm^2 tissue culture plates, washed with 5 mM EDTA in PBS (HyClone Dulbecco's Phosphate Buffered Saline 1x with Calcium and Magnesium, Cat #SH30264.01, hereafter referred to simply as PBS) and scraped into 50 ml tubes. After centrifugation (2KxG, 5 min at 4° C.), the supernatant was aspirated and the pellets frozen and stored at -80\°C. Cells were resuspended in PBS in the presence of 1 tablet of protease inhibitor cocktail (Roche, Cat. #11836145001) per 50 mL. Each cell pellet from a 15 cm plate was resuspended in 10 mL, stored on ice, and homogenized for 45 sec prior to addition to the reactions. Competition binding experiments in 96 well polypropylene plates were performed using [3H]-SB674042 (Moraveck Corporation, specific activity=35.3 Ci/mmol), diluted to a 10 nM concentration in PBS (4 nM final). Compounds were solubilized in 100% DMSO (Acros Organics, Cat. #61042-1000) and tested over a range of 7 concentrations (from 0.1 nM to 10 uM). The final concentration of DMSO in the reactions is equal to or less than 0.1%. Total and nonspecific binding was determined in the absence and presence of 10 uM almorexant. The total volume of each reaction is 200 uL (20 uL of diluted compounds, 80 uL of [3H]-(1-(5-(2-fluoro-phenyl)-2-methyl-thiazol-4-yl)-1-((S)-2-(5-phenyl-(1,3,4)oxadiazol-2-ylmethyl)-pyrrolidin-1-yl)-methanone) diluted in PBS and 100 uL of the cell suspension). Reactions were run for 60 min at room temperature and terminated by filtration through GF/C filter plates (PerkinElmer, Cat. #6005174) presoaked in 0.3% polyethylenimine using the cell harvester (PerkinElmer Filtermate). The plates were washed 3 times by aspirating 30 ml PBS through the plates. Plates were dried in 55° C. oven for 60 min, scintillation fluid was added, and the radioactivity was counted on a Topcount (Packard).Radioligand Binding Assay: Human Embryonic Kidney 293 cells (HEK293) stably expressing rat orexin 1 receptor (Genebank accession number NM_001525) or Chinese ovary cells (CHO) stably expressing human orexin 1 receptor (Genebank accession number NM_001526) were grown to confluency in DMEM (Hyclone, cat #SH30022), 10% FBS, 1x Pen/Strep, 1x sodium pyruvate, 10 mM HEPES, 600 ug/mL G418 and DMEM/F12 (Gibco, Cat #11039), 10% FBS, 1x Pen/Strep, 600 ug/mL G418 media, respectively on 150 cm^2 tissue culture plates, washed with 5 mM EDTA in PBS (HyClone Dulbecco's Phosphate Buffered Saline 1x with Calcium and Magnesium, Cat #SH30264.01, hereafter referred to simply as PBS) and scraped into 50 ml tubes.

The final concentration of DMSO in the reactions is equal to or less than 0.1%. Total and nonspecific binding was determined in the absence and presence of 10 uM almorexant. The total volume of each reaction is 200 uL (20 uL of diluted compounds, 80 uL of [3H]-(1-(5-(2-fluoro-phenyl)-2-methyl-thiazol-4-yl)-1-((S)-2-(5-phenyl-(1,3,4)oxadiazol-2-ylmethyl)-pyrrolidin-1-yl)-methanone) diluted in PBS and 100 uL of the cell suspension). Reactions were run for 60 min at room temperature and terminated by filtration through GF/C filter plates (PerkinElmer, Cat. #6005174) presoaked in 0.3% polyethylenimine using the cell harvester (PerkinElmer Filtermate). The plates were washed 3 times by aspirating 30 ml PBS through the plates. Plates were dried in 55° C. oven for 60 min, scintillation fluid was added, and the radioactivity was counted on a Topcount (Packard).

Radioligand Binding Assay: Human Embryonic Kidney 293 cells (HEK293) stably expressing rat orexin 1 receptor (Genebank accession number NM_001525) or Chinese ovary cells (CHO) stably expressing human orexin 1 receptor (Genebank accession number NM_001526) were grown to confluency in DMEM (Hyclone, cat #SH30022), 10% FBS, 1x Pen/Strep, 1x sodium pyruvate, 10 mM HEPES, 600 ug/mL G418 and DMEM/F12 (Gibco, Cat #11039), 10% FBS, 1x Pen/Strep, 600 ug/mL G418 media, respectively on 150 cm^2 tissue culture plates, washed with 5 mM EDTA in PBS (HyClone Dulbecco's Phosphate Buffered Saline 1x with Calcium and Magnesium, Cat #SH30264.01, hereafter referred to simply as PBS) and scraped into 50 ml tubes. After centrifugation (2KxG, 5 min at 4° C.), the supernatant was aspirated and the pellets frozen and stored at -80\°C. Cells were resuspended in PBS in the presence of 1 tablet of protease inhibitor cocktail (Roche, Cat. #11836145001) per 50 mL. Each cell pellet from a 15 cm plate was resuspended in 10 mL, stored on ice, and homogenized for 45 sec prior to addition to the reactions. Competition binding experiments in 96 well polypropylene plates were performed using [3H]-SB674042 (Moraveck Corporation, specific activity=35.3 Ci/mmol), diluted to a 10 nM concentration in PBS (4 nM final). Compounds were solubilized in 100% DMSO (Acros Organics, Cat. #61042-1000) and tested over a range of 7 concentrations (from 0.1 nM to 10 uM). The final concentration of DMSO in the reactions is equal to or less than 0.1%. Total and nonspecific binding was determined in the absence and presence of 10 uM almorexant. The total volume of each reaction is 200 uL (20 uL of diluted compounds, 80 uL of [3H]-(1-(5-(2-fluoro-phenyl)-2-methyl-thiazol-4-yl)-1-((S)-2-(5-phenyl-(1,3,4)oxadiazol-2-ylmethyl)-pyrrolidin-1-yl)-methanone) diluted in PBS and 100 uL of the cell suspension). Reactions were run for 60 min at room temperature and terminated by filtration through GF/C filter plates (PerkinElmer, Cat. #6005174) presoaked in 0.3% polyethylenimine using the cell harvester (PerkinElmer Filtermate). The plates were washed 3 times by aspirating 30 ml PBS through the plates. Plates were dried in 55° C. oven for 60 min, scintillation fluid was added, and the radioactivity was counted on a Topcount (Packard).Radioligand Binding Assay: Human Embryonic Kidney 293 cells (HEK293) stably expressing rat orexin 1 receptor (Genebank accession number NM_001525) or Chinese ovary cells (CHO) stably expressing human orexin 1 receptor (Genebank accession number NM_001526) were grown to confluency in DMEM (Hyclone, cat #SH30022), 10% FBS, 1x Pen/Strep, 1x sodium pyruvate, 10 mM HEPES, 600 ug/mL G418 and DMEM/F12 (Gibco, Cat #11039), 10% FBS, 1x Pen/Strep, 600 ug/mL G418 media, respectively on 150 cm^2 tissue culture plates, washed with 5 mM EDTA in PBS (HyClone Dulbecco's Phosphate Buffered Saline 1x with Calcium and Magnesium, Cat #SH30264.01, hereafter referred to simply as PBS) and scraped into 50 ml tubes.

The total volume of each reaction is 200 uL (20 uL of diluted compounds, 80 uL of [3H]-(1-(5-(2-fluoro-phenyl)-2-methyl-thiazol-4-yl)-1-((S)-2-(5-phenyl-(1,3,4)oxadiazol-2-ylmethyl)-pyrrolidin-1-yl)-methanone) diluted in PBS and 100 uL of the cell suspension). Reactions were run for 60 min at room temperature and terminated by filtration through GF/C filter plates (PerkinElmer, Cat. #6005174) presoaked in 0.3% polyethylenimine using the cell harvester (PerkinElmer Filtermate). The plates were washed 3 times by aspirating 30 ml PBS through the plates. Plates were dried in 55° C. oven for 60 min, scintillation fluid was added, and the radioactivity was counted on a Topcount (Packard).

Competition binding experiments in 96 well polypropylene plates were performed using [3H]-SB674042 (Moraveck Corporation, specific activity=35.3 Ci/mmol), diluted to a 10 nM concentration in PBS (4 nM final). Compounds were solubilized in 100% DMSO (Acros Organics, Cat. #61042-1000) and tested over a range of 7 concentrations (from 0.1 nM to 10 uM). The final concentration of DMSO in the reactions is equal to or less than 0.1%. Total and nonspecific binding was determined in the absence and presence of 10 uM almorexant. The total volume of each reaction is 200 uL (20 uL of diluted compounds, 80 uL of [3H]-(1-(5-(2-fluoro-phenyl)-2-methyl-thiazol-4-yl)-1-((S)-2-(5-phenyl-(1,3,4)oxadiazol-2-ylmethyl)-pyrrolidin-1-yl)-methanone) diluted in PBS and 100 uL of the cell suspension). Reactions were run for 60 min at room temperature and terminated by filtration through GF/C filter plates (PerkinElmer, Cat. #6005174) presoaked in 0.3% polyethylenimine using the cell harvester (PerkinElmer Filtermate). The plates were washed 3 times by aspirating 30 ml PBS through the plates. Plates were dried in 55° C. oven for 60 min, scintillation fluid was added, and the radioactivity was counted on a Topcount (Packard).

Radioligand Binding Assay: Human Embryonic Kidney 293 cells (HEK293) stably expressing rat orexin 1 receptor (Genebank accession number NM_001525) or Chinese ovary cells (CHO) stably expressing human orexin 1 receptor (Genebank accession number NM_001526) were grown to confluency in DMEM (Hyclone, cat #SH30022), 10% FBS, 1x Pen/Strep, 1x sodium pyruvate, 10 mM HEPES, 600 ug/mL G418 and DMEM/F12 (Gibco, Cat #11039), 10% FBS, 1x Pen/Strep, 600 ug/mL G418 media, respectively on 150 cm^2 tissue culture plates, washed with 5 mM EDTA in PBS (HyClone Dulbecco's Phosphate Buffered Saline 1x with Calcium and Magnesium, Cat #SH30264.01, hereafter referred to simply as PBS) and scraped into 50 ml tubes. After centrifugation (2KxG, 5 min at 4° C.), the supernatant was aspirated and the pellets frozen and stored at -80\°C. Cells were resuspended in PBS in the presence of 1 tablet of protease inhibitor cocktail (Roche, Cat. #11836145001) per 50 mL. Each cell pellet from a 15 cm plate was resuspended in 10 mL, stored on ice, and homogenized for 45 sec prior to addition to the reactions. Competition binding experiments in 96 well polypropylene plates were performed using [3H]-SB674042 (Moraveck Corporation, specific activity=35.3 Ci/mmol), diluted to a 10 nM concentration in PBS (4 nM final). Compounds were solubilized in 100% DMSO (Acros Organics, Cat. #61042-1000) and tested over a range of 7 concentrations (from 0.1 nM to 10 uM). The final concentration of DMSO in the reactions is equal to or less than 0.1%. Total and nonspecific binding was determined in the absence and presence of 10 uM almorexant. The total volume of each reaction is 200 uL (20 uL of diluted compounds, 80 uL of [3H]-(1-(5-(2-fluoro-phenyl)-2-methyl-thiazol-4-yl)-1-((S)-2-(5-phenyl-(1,3,4)oxadiazol-2-ylmethyl)-pyrrolidin-1-yl)-methanone) diluted in PBS and 100 uL of the cell suspension). Reactions were run for 60 min at room temperature and terminated by filtration through GF/C filter plates (PerkinElmer, Cat. #6005174) presoaked in 0.3% polyethylenimine using the cell harvester (PerkinElmer Filtermate). The plates were washed 3 times by aspirating 30 ml PBS through the plates. Plates were dried in 55° C. oven for 60 min, scintillation fluid was added, and the radioactivity was counted on a Topcount (Packard).Radioligand Binding Assay: Human Embryonic Kidney 293 cells (HEK293) stably expressing rat orexin 1 receptor (Genebank accession number NM_001525) or Chinese ovary cells (CHO) stably expressing human orexin 1 receptor (Genebank accession number NM_001526) were grown to confluency in DMEM (Hyclone, cat #SH30022), 10% FBS, 1x Pen/Strep, 1x sodium pyruvate, 10 mM HEPES, 600 ug/mL G418 and DMEM/F12 (Gibco, Cat #11039), 10% FBS, 1x Pen/Strep, 600 ug/mL G418 media, respectively on 150 cm^2 tissue culture plates, washed with 5 mM EDTA in PBS (HyClone Dulbecco's Phosphate Buffered Saline 1x with Calcium and Magnesium, Cat #SH30264.01, hereafter referred to simply as PBS) and scraped into 50 ml tubes.

After centrifugation (2KxG, 5 min at 4° C.), the supernatant was aspirated and the pellets frozen and stored at -80\°C. Cells were resuspended in PBS in the presence of 1 tablet of protease inhibitor cocktail (Roche, Cat. #11836145001) per 50 mL. Each cell pellet from a 15 cm plate was resuspended in 10 mL, stored on ice, and homogenized for 45 sec prior to addition to the reactions. Competition binding experiments in 96 well polypropylene plates were performed using [3H]-SB674042 (Moraveck Corporation, specific activity=35.3 Ci/mmol), diluted to a 10 nM concentration in PBS (4 nM final). Compounds were solubilized in 100% DMSO (Acros Organics, Cat. #61042-1000) and tested over a range of 7 concentrations (from 0.1 nM to 10 uM). The final concentration of DMSO in the reactions is equal to or less than 0.1%. Total and nonspecific binding was determined in the absence and presence of 10 uM almorexant. The total volume of each reaction is 200 uL (20 uL of diluted compounds, 80 uL of [3H]-(1-(5-(2-fluoro-phenyl)-2-methyl-thiazol-4-yl)-1-((S)-2-(5-phenyl-(1,3,4)oxadiazol-2-ylmethyl)-pyrrolidin-1-yl)-methanone) diluted in PBS and 100 uL of the cell suspension). Reactions were run for 60 min at room temperature and terminated by filtration through GF/C filter plates (PerkinElmer, Cat. #6005174) presoaked in 0.3% polyethylenimine using the cell harvester (PerkinElmer Filtermate). The plates were washed 3 times by aspirating 30 ml PBS through the plates. Plates were dried in 55° C. oven for 60 min, scintillation fluid was added, and the radioactivity was counted on a Topcount (Packard).

After centrifugation (2KxG, 5 min at 4° C.), the supernatant was aspirated and the pellets frozen and stored at -80\°C. Cells were resuspended in PBS in the presence of 1 tablet of protease inhibitor cocktail (Roche, Cat. #11836145001) per 50 mL. Each cell pellet from a 15 cm plate was resuspended in 10 mL, stored on ice, and homogenized for 45 sec prior to addition to the reactions. Competition binding experiments in 96 well polypropylene plates were performed using [3H]-SB674042 (Moraveck Corporation, specific activity=35.3 Ci/mmol), diluted to a 10 nM concentration in PBS (4 nM final). Compounds were solubilized in 100% DMSO (Acros Organics, Cat. #61042-1000) and tested over a range of 7 concentrations (from 0.1 nM to 10 uM). The final concentration of DMSO in the reactions is equal to or less than 0.1%. Total and nonspecific binding was determined in the absence and presence of 10 uM almorexant. The total volume of each reaction is 200 uL (20 uL of diluted compounds, 80 uL of [3H]-(1-(5-(2-fluoro-phenyl)-2-methyl-thiazol-4-yl)-1-((S)-2-(5-phenyl-(1,3,4)oxadiazol-2-ylmethyl)-pyrrolidin-1-yl)-methanone) diluted in PBS and 100 uL of the cell suspension).

Compounds were solubilized in 100% DMSO (Acros Organics, Cat. #61042-1000) and tested over a range of 7 concentrations (from 0.1 nM to 10 uM). The final concentration of DMSO in the reactions is equal to or less than 0.1%. Total and nonspecific binding was determined in the absence and presence of 10 uM almorexant. The total volume of each reaction is 200 uL (20 uL of diluted compounds, 80 uL of [3H]-(1-(5-(2-fluoro-phenyl)-2-methyl-thiazol-4-yl)-1-((S)-2-(5-phenyl-(1,3,4)oxadiazol-2-ylmethyl)-pyrrolidin-1-yl)-methanone) diluted in PBS and 100 uL of the cell suspension). Reactions were run for 60 min at room temperature and terminated by filtration through GF/C filter plates (PerkinElmer, Cat. #6005174) presoaked in 0.3% polyethylenimine using the cell harvester (PerkinElmer Filtermate). The plates were washed 3 times by aspirating 30 ml PBS through the plates. Plates were dried in 55° C. oven for 60 min, scintillation fluid was added, and the radioactivity was counted on a Topcount (Packard).

After centrifugation (2KxG, 5 min at 4° C.), the supernatant was aspirated and the pellets frozen and stored at -80\°C. Cells were resuspended in PBS in the presence of 1 tablet of protease inhibitor cocktail (Roche, Cat. #11836145001) per 50 mL. Each cell pellet from a 15 cm plate was resuspended in 10 mL, stored on ice, and homogenized for 45 sec prior to addition to the reactions. Competition binding experiments in 96 well polypropylene plates were performed using [3H]-SB674042 (Moraveck Corporation, specific activity=35.3 Ci/mmol), diluted to a 10 nM concentration in PBS (4 nM final).

After centrifugation (2KxG, 5 min at 4° C.), the supernatant was aspirated and the pellets frozen and stored at -80\°C. Cells were resuspended in PBS in the presence of 1 tablet of protease inhibitor cocktail (Roche, Cat. #11836145001) per 50 mL. Each cell pellet from a 15 cm plate was resuspended in 10 mL, stored on ice, and homogenized for 45 sec prior to addition to the reactions. Competition binding experiments in 96 well polypropylene plates were performed using [3H]-SB674042 (Moraveck Corporation, specific activity=35.3 Ci/mmol), diluted to a 10 nM concentration in PBS (4 nM final). Compounds were solubilized in 100% DMSO (Acros Organics, Cat. #61042-1000) and tested over a range of 7 concentrations (from 0.1 nM to 10 uM). The final concentration of DMSO in the reactions is equal to or less than 0.1%. Total and nonspecific binding was determined in the absence and presence of 10 uM almorexant. The total volume of each reaction is 200 uL (20 uL of diluted compounds, 80 uL of [3H]-(1-(5-(2-fluoro-phenyl)-2-methyl-thiazol-4-yl)-1-((S)-2-(5-phenyl-(1,3,4)oxadiazol-2-ylmethyl)-pyrrolidin-1-yl)-methanone) diluted in PBS and 100 uL of the cell suspension). Reactions were run for 60 min at room temperature and terminated by filtration through GF/C filter plates (PerkinElmer, Cat. #6005174) presoaked in 0.3% polyethylenimine using the cell harvester (PerkinElmer Filtermate). The plates were washed 3 times by aspirating 30 ml PBS through the plates. Plates were dried in 55° C. oven for 60 min, scintillation fluid was added, and the radioactivity was counted on a Topcount (Packard).Radioligand Binding Assay: Human Embryonic Kidney 293 cells (HEK293) stably expressing rat orexin 1 receptor (Genebank accession number NM_001525) or Chinese ovary cells (CHO) stably expressing human orexin 1 receptor (Genebank accession number NM_001526) were grown to confluency in DMEM (Hyclone, cat #SH30022), 10% FBS, 1x Pen/Strep, 1x sodium pyruvate, 10 mM HEPES, 600 ug/mL G418 and DMEM/F12 (Gibco, Cat #11039), 10% FBS, 1x Pen/Strep, 600 ug/mL G418 media, respectively on 150 cm^2 tissue culture plates, washed with 5 mM EDTA in PBS (HyClone Dulbecco's Phosphate Buffered Saline 1x with Calcium and Magnesium, Cat #SH30264.01, hereafter referred to simply as PBS) and scraped into 50 ml tubes.

Radioligand Binding Assay: Human Embryonic Kidney 293 cells (HEK293) stably expressing rat orexin 1 receptor (Genebank accession number NM_001525) or Chinese ovary cells (CHO) stably expressing human orexin 1 receptor (Genebank accession number NM_001526) were grown to confluency in DMEM (Hyclone, cat #SH30022), 10% FBS, 1x Pen/Strep, 1x sodium pyruvate, 10 mM HEPES, 600 ug/mL G418 and DMEM/F12 (Gibco, Cat #11039), 10% FBS, 1x Pen/Strep, 600 ug/mL G418 media, respectively on 150 cm^2 tissue culture plates, washed with 5 mM EDTA in PBS (HyClone Dulbecco's Phosphate Buffered Saline 1x with Calcium and Magnesium, Cat #SH30264.01, hereafter referred to simply as PBS) and scraped into 50 ml tubes. After centrifugation (2KxG, 5 min at 4° C.), the supernatant was aspirated and the pellets frozen and stored at -80\°C. Cells were resuspended in PBS in the presence of 1 tablet of protease inhibitor cocktail (Roche, Cat. #11836145001) per 50 mL. Each cell pellet from a 15 cm plate was resuspended in 10 mL, stored on ice, and homogenized for 45 sec prior to addition to the reactions. Competition binding experiments in 96 well polypropylene plates were performed using [3H]-SB674042 (Moraveck Corporation, specific activity=35.3 Ci/mmol), diluted to a 10 nM concentration in PBS (4 nM final). Compounds were solubilized in 100% DMSO (Acros Organics, Cat. #61042-1000) and tested over a range of 7 concentrations (from 0.1 nM to 10 uM). The final concentration of DMSO in the reactions is equal to or less than 0.1%. Total and nonspecific binding was determined in the absence and presence of 10 uM almorexant. The total volume of each reaction is 200 uL (20 uL of diluted compounds, 80 uL of [3H]-(1-(5-(2-fluoro-phenyl)-2-methyl-thiazol-4-yl)-1-((S)-2-(5-phenyl-(1,3,4)oxadiazol-2-ylmethyl)-pyrrolidin-1-yl)-methanone) diluted in PBS and 100 uL of the cell suspension). Reactions were run for 60 min at room temperature and terminated by filtration through GF/C filter plates (PerkinElmer, Cat. #6005174) presoaked in 0.3% polyethylenimine using the cell harvester (PerkinElmer Filtermate). The plates were washed 3 times by aspirating 30 ml PBS through the plates. Plates were dried in 55° C. oven for 60 min, scintillation fluid was added, and the radioactivity was counted on a Topcount (Packard).Radioligand Binding Assay: Human Embryonic Kidney 293 cells (HEK293) stably expressing rat orexin 1 receptor (Genebank accession number NM_001525) or Chinese ovary cells (CHO) stably expressing human orexin 1 receptor (Genebank accession number NM_001526) were grown to confluency in DMEM (Hyclone, cat #SH30022), 10% FBS, 1x Pen/Strep, 1x sodium pyruvate, 10 mM HEPES, 600 ug/mL G418 and DMEM/F12 (Gibco, Cat #11039), 10% FBS, 1x Pen/Strep, 600 ug/mL G418 media, respectively on 150 cm^2 tissue culture plates, washed with 5 mM EDTA in PBS (HyClone Dulbecco's Phosphate Buffered Saline 1x with Calcium and Magnesium, Cat #SH30264.01, hereafter referred to simply as PBS) and scraped into 50 ml tubes.

The final concentration of DMSO in the reactions is equal to or less than 0.1%. Total and nonspecific binding was determined in the absence and presence of 10 uM almorexant. The total volume of each reaction is 200 uL (20 uL of diluted compounds, 80 uL of [3H]-(1-(5-(2-fluoro-phenyl)-2-methyl-thiazol-4-yl)-1-((S)-2-(5-phenyl-(1,3,4)oxadiazol-2-ylmethyl)-pyrrolidin-1-yl)-methanone) diluted in PBS and 100 uL of the cell suspension). Reactions were run for 60 min at room temperature and terminated by filtration through GF/C filter plates (PerkinElmer, Cat. #6005174) presoaked in 0.3% polyethylenimine using the cell harvester (PerkinElmer Filtermate). The plates were washed 3 times by aspirating 30 ml PBS through the plates. Plates were dried in 55° C. oven for 60 min, scintillation fluid was added, and the radioactivity was counted on a Topcount (Packard).

Radioligand Binding Assay: Human Embryonic Kidney 293 cells (HEK293) stably expressing rat orexin 1 receptor (Genebank accession number NM_001525) or Chinese ovary cells (CHO) stably expressing human orexin 1 receptor (Genebank accession number NM_001526) were grown to confluency in DMEM (Hyclone, cat #SH30022), 10% FBS, 1x Pen/Strep, 1x sodium pyruvate, 10 mM HEPES, 600 ug/mL G418 and DMEM/F12 (Gibco, Cat #11039), 10% FBS, 1x Pen/Strep, 600 ug/mL G418 media, respectively on 150 cm^2 tissue culture plates, washed with 5 mM EDTA in PBS (HyClone Dulbecco's Phosphate Buffered Saline 1x with Calcium and Magnesium, Cat #SH30264.01, hereafter referred to simply as PBS) and scraped into 50 ml tubes. After centrifugation (2KxG, 5 min at 4° C.), the supernatant was aspirated and the pellets frozen and stored at -80\°C. Cells were resuspended in PBS in the presence of 1 tablet of protease inhibitor cocktail (Roche, Cat. #11836145001) per 50 mL. Each cell pellet from a 15 cm plate was resuspended in 10 mL, stored on ice, and homogenized for 45 sec prior to addition to the reactions. Competition binding experiments in 96 well polypropylene plates were performed using [3H]-SB674042 (Moraveck Corporation, specific activity=35.3 Ci/mmol), diluted to a 10 nM concentration in PBS (4 nM final). Compounds were solubilized in 100% DMSO (Acros Organics, Cat. #61042-1000) and tested over a range of 7 concentrations (from 0.1 nM to 10 uM). The final concentration of DMSO in the reactions is equal to or less than 0.1%. Total and nonspecific binding was determined in the absence and presence of 10 uM almorexant. The total volume of each reaction is 200 uL (20 uL of diluted compounds, 80 uL of [3H]-(1-(5-(2-fluoro-phenyl)-2-methyl-thiazol-4-yl)-1-((S)-2-(5-phenyl-(1,3,4)oxadiazol-2-ylmethyl)-pyrrolidin-1-yl)-methanone) diluted in PBS and 100 uL of the cell suspension).

The total volume of each reaction is 200 uL (20 uL of diluted compounds, 80 uL of [3H]-(1-(5-(2-fluoro-phenyl)-2-methyl-thiazol-4-yl)-1-((S)-2-(5-phenyl-(1,3,4)oxadiazol-2-ylmethyl)-pyrrolidin-1-yl)-methanone) diluted in PBS and 100 uL of the cell suspension). Reactions were run for 60 min at room temperature and terminated by filtration through GF/C filter plates (PerkinElmer, Cat. #6005174) presoaked in 0.3% polyethylenimine using the cell harvester (PerkinElmer Filtermate). The plates were washed 3 times by aspirating 30 ml PBS through the plates. Plates were dried in 55° C. oven for 60 min, scintillation fluid was added, and the radioactivity was counted on a Topcount (Packard).

After centrifugation (2K xG, 5 min at 40 C.), the supernatant was aspirated and the pellets frozen and stored at -80 C. Cells were resuspended in PBS in the presence of 1 tablet of protease inhibitor cocktail (Roche, Cat. #11836145001) per 50 mL. Each cell pellet from a 15 cm plate was resuspended in 10 mL, stored on ice, and homogenized for 45 sec just prior to addition to the reactions. Competition binding experiments in 96 well polypropylene plates were performed using [3H]-EMPA (Moraveck Corporation, specific activity=29.6 Ci/mmol).Radioligand Binding Assay: HEK293 stably expressing human orexin 2 receptor (Genebank accession number NM001526) were grown to confluency in DMEM (Hyclone, cat #SH30022), 10% FBS, 1x Pen/Strep, 1x NaPyruvate, 10 mM HEPES, 600 ug/ml G418 media on 150 cm2 tissue culture plates, washed with 5 mM EDTA in PBS (HyClone Dulbecco's Phosphate Buffered Saline 1x with Calcium and Magnesium, Cat # SH30264.01, hereafter referred to simply as PBS) and scraped into 50 ml tubes.

Radioligand Binding Assay: Human Embryonic Kidney 293 cells (HEK293) stably expressing rat orexin 1 receptor (Genebank accession number NM_001525) or Chinese ovary cells (CHO) stably expressing human orexin 1 receptor (Genebank accession number NM_001526) were grown to confluency in DMEM (Hyclone, cat #SH30022), 10% FBS, 1x Pen/Strep, 1x sodium pyruvate, 10 mM HEPES, 600 ug/mL G418 and DMEM/F12 (Gibco, Cat #11039), 10% FBS, 1x Pen/Strep, 600 ug/mL G418 media, respectively on 150 cm^2 tissue culture plates, washed with 5 mM EDTA in PBS (HyClone Dulbecco's Phosphate Buffered Saline 1x with Calcium and Magnesium, Cat #SH30264.01, hereafter referred to simply as PBS) and scraped into 50 ml tubes. After centrifugation (2KxG, 5 min at 4° C.), the supernatant was aspirated and the pellets frozen and stored at -80\°C. Cells were resuspended in PBS in the presence of 1 tablet of protease inhibitor cocktail (Roche, Cat. #11836145001) per 50 mL. Each cell pellet from a 15 cm plate was resuspended in 10 mL, stored on ice, and homogenized for 45 sec prior to addition to the reactions. Competition binding experiments in 96 well polypropylene plates were performed using [3H]-SB674042 (Moraveck Corporation, specific activity=35.3 Ci/mmol), diluted to a 10 nM concentration in PBS (4 nM final). Compounds were solubilized in 100% DMSO (Acros Organics, Cat. #61042-1000) and tested over a range of 7 concentrations (from 0.1 nM to 10 uM). The final concentration of DMSO in the reactions is equal to or less than 0.1%. Total and nonspecific binding was determined in the absence and presence of 10 uM almorexant. The total volume of each reaction is 200 uL (20 uL of diluted compounds, 80 uL of [3H]-(1-(5-(2-fluoro-phenyl)-2-methyl-thiazol-4-yl)-1-((S)-2-(5-phenyl-(1,3,4)oxadiazol-2-ylmethyl)-pyrrolidin-1-yl)-methanone) diluted in PBS and 100 uL of the cell suspension). Reactions were run for 60 min at room temperature and terminated by filtration through GF/C filter plates (PerkinElmer, Cat. #6005174) presoaked in 0.3% polyethylenimine using the cell harvester (PerkinElmer Filtermate). The plates were washed 3 times by aspirating 30 ml PBS through the plates. Plates were dried in 55° C. oven for 60 min, scintillation fluid was added, and the radioactivity was counted on a Topcount (Packard).Radioligand Binding Assay: Human Embryonic Kidney 293 cells (HEK293) stably expressing rat orexin 1 receptor (Genebank accession number NM_001525) or Chinese ovary cells (CHO) stably expressing human orexin 1 receptor (Genebank accession number NM_001526) were grown to confluency in DMEM (Hyclone, cat #SH30022), 10% FBS, 1x Pen/Strep, 1x sodium pyruvate, 10 mM HEPES, 600 ug/mL G418 and DMEM/F12 (Gibco, Cat #11039), 10% FBS, 1x Pen/Strep, 600 ug/mL G418 media, respectively on 150 cm^2 tissue culture plates, washed with 5 mM EDTA in PBS (HyClone Dulbecco's Phosphate Buffered Saline 1x with Calcium and Magnesium, Cat #SH30264.01, hereafter referred to simply as PBS) and scraped into 50 ml tubes.

After centrifugation (2KxG, 5 min at 4° C.), the supernatant was aspirated and the pellets frozen and stored at -80\°C. Cells were resuspended in PBS in the presence of 1 tablet of protease inhibitor cocktail (Roche, Cat. #11836145001) per 50 mL. Each cell pellet from a 15 cm plate was resuspended in 10 mL, stored on ice, and homogenized for 45 sec prior to addition to the reactions. Competition binding experiments in 96 well polypropylene plates were performed using [3H]-SB674042 (Moraveck Corporation, specific activity=35.3 Ci/mmol), diluted to a 10 nM concentration in PBS (4 nM final). Compounds were solubilized in 100% DMSO (Acros Organics, Cat. #61042-1000) and tested over a range of 7 concentrations (from 0.1 nM to 10 uM). The final concentration of DMSO in the reactions is equal to or less than 0.1%. Total and nonspecific binding was determined in the absence and presence of 10 uM almorexant. The total volume of each reaction is 200 uL (20 uL of diluted compounds, 80 uL of [3H]-(1-(5-(2-fluoro-phenyl)-2-methyl-thiazol-4-yl)-1-((S)-2-(5-phenyl-(1,3,4)oxadiazol-2-ylmethyl)-pyrrolidin-1-yl)-methanone) diluted in PBS and 100 uL of the cell suspension).

After centrifugation (2KxG, 5 min at 4° C.), the supernatant was aspirated and the pellets frozen and stored at -80\°C. Cells were resuspended in PBS in the presence of 1 tablet of protease inhibitor cocktail (Roche, Cat. #11836145001) per 50 mL. Each cell pellet from a 15 cm plate was resuspended in 10 mL, stored on ice, and homogenized for 45 sec prior to addition to the reactions. Competition binding experiments in 96 well polypropylene plates were performed using [3H]-SB674042 (Moraveck Corporation, specific activity=35.3 Ci/mmol), diluted to a 10 nM concentration in PBS (4 nM final). Compounds were solubilized in 100% DMSO (Acros Organics, Cat. #61042-1000) and tested over a range of 7 concentrations (from 0.1 nM to 10 uM). The final concentration of DMSO in the reactions is equal to or less than 0.1%. Total and nonspecific binding was determined in the absence and presence of 10 uM almorexant. The total volume of each reaction is 200 uL (20 uL of diluted compounds, 80 uL of [3H]-(1-(5-(2-fluoro-phenyl)-2-methyl-thiazol-4-yl)-1-((S)-2-(5-phenyl-(1,3,4)oxadiazol-2-ylmethyl)-pyrrolidin-1-yl)-methanone) diluted in PBS and 100 uL of the cell suspension). Reactions were run for 60 min at room temperature and terminated by filtration through GF/C filter plates (PerkinElmer, Cat. #6005174) presoaked in 0.3% polyethylenimine using the cell harvester (PerkinElmer Filtermate). The plates were washed 3 times by aspirating 30 ml PBS through the plates. Plates were dried in 55° C. oven for 60 min, scintillation fluid was added, and the radioactivity was counted on a Topcount (Packard).Radioligand Binding Assay: Human Embryonic Kidney 293 cells (HEK293) stably expressing rat orexin 1 receptor (Genebank accession number NM_001525) or Chinese ovary cells (CHO) stably expressing human orexin 1 receptor (Genebank accession number NM_001526) were grown to confluency in DMEM (Hyclone, cat #SH30022), 10% FBS, 1x Pen/Strep, 1x sodium pyruvate, 10 mM HEPES, 600 ug/mL G418 and DMEM/F12 (Gibco, Cat #11039), 10% FBS, 1x Pen/Strep, 600 ug/mL G418 media, respectively on 150 cm^2 tissue culture plates, washed with 5 mM EDTA in PBS (HyClone Dulbecco's Phosphate Buffered Saline 1x with Calcium and Magnesium, Cat #SH30264.01, hereafter referred to simply as PBS) and scraped into 50 ml tubes.

Cells were resuspended in PBS in the presence of 1 tablet of protease inhibitor cocktail (Roche, Cat. #11836145001) per 50 mL. Each cell pellet from a 15 cm plate was resuspended in 10 mL, stored on ice, and homogenized for 45 sec prior to addition to the reactions. Competition binding experiments in 96 well polypropylene plates were performed using [3H]-SB674042 (Moraveck Corporation, specific activity=35.3 Ci/mmol), diluted to a 10 nM concentration in PBS (4 nM final). Compounds were solubilized in 100% DMSO (Acros Organics, Cat. #61042-1000) and tested over a range of 7 concentrations (from 0.1 nM to 10 uM). The final concentration of DMSO in the reactions is equal to or less than 0.1%. Total and nonspecific binding was determined in the absence and presence of 10 uM almorexant. The total volume of each reaction is 200 uL (20 uL of diluted compounds, 80 uL of [3H]-(1-(5-(2-fluoro-phenyl)-2-methyl-thiazol-4-yl)-1-((S)-2-(5-phenyl-(1,3,4)oxadiazol-2-ylmethyl)-pyrrolidin-1-yl)-methanone) diluted in PBS and 100 uL of the cell suspension). Reactions were run for 60 min at room temperature and terminated by filtration through GF/C filter plates (PerkinElmer, Cat. #6005174) presoaked in 0.3% polyethylenimine using the cell harvester (PerkinElmer Filtermate). The plates were washed 3 times by aspirating 30 ml PBS through the plates. Plates were dried in 55° C. oven for 60 min, scintillation fluid was added, and the radioactivity was counted on a Topcount (Packard).

Radioligand Binding Assay: Human Embryonic Kidney 293 cells (HEK293) stably expressing rat orexin 1 receptor (Genebank accession number NM_001525) or Chinese ovary cells (CHO) stably expressing human orexin 1 receptor (Genebank accession number NM_001526) were grown to confluency in DMEM (Hyclone, cat #SH30022), 10% FBS, 1x Pen/Strep, 1x sodium pyruvate, 10 mM HEPES, 600 ug/mL G418 and DMEM/F12 (Gibco, Cat #11039), 10% FBS, 1x Pen/Strep, 600 ug/mL G418 media, respectively on 150 cm^2 tissue culture plates, washed with 5 mM EDTA in PBS (HyClone Dulbecco's Phosphate Buffered Saline 1x with Calcium and Magnesium, Cat #SH30264.01, hereafter referred to simply as PBS) and scraped into 50 ml tubes. After centrifugation (2KxG, 5 min at 4° C.), the supernatant was aspirated and the pellets frozen and stored at -80\°C. Cells were resuspended in PBS in the presence of 1 tablet of protease inhibitor cocktail (Roche, Cat. #11836145001) per 50 mL. Each cell pellet from a 15 cm plate was resuspended in 10 mL, stored on ice, and homogenized for 45 sec prior to addition to the reactions. Competition binding experiments in 96 well polypropylene plates were performed using [3H]-SB674042 (Moraveck Corporation, specific activity=35.3 Ci/mmol), diluted to a 10 nM concentration in PBS (4 nM final). Compounds were solubilized in 100% DMSO (Acros Organics, Cat. #61042-1000) and tested over a range of 7 concentrations (from 0.1 nM to 10 uM). The final concentration of DMSO in the reactions is equal to or less than 0.1%. Total and nonspecific binding was determined in the absence and presence of 10 uM almorexant. The total volume of each reaction is 200 uL (20 uL of diluted compounds, 80 uL of [3H]-(1-(5-(2-fluoro-phenyl)-2-methyl-thiazol-4-yl)-1-((S)-2-(5-phenyl-(1,3,4)oxadiazol-2-ylmethyl)-pyrrolidin-1-yl)-methanone) diluted in PBS and 100 uL of the cell suspension). Reactions were run for 60 min at room temperature and terminated by filtration through GF/C filter plates (PerkinElmer, Cat. #6005174) presoaked in 0.3% polyethylenimine using the cell harvester (PerkinElmer Filtermate). The plates were washed 3 times by aspirating 30 ml PBS through the plates. Plates were dried in 55° C. oven for 60 min, scintillation fluid was added, and the radioactivity was counted on a Topcount (Packard).Radioligand Binding Assay: Human Embryonic Kidney 293 cells (HEK293) stably expressing rat orexin 1 receptor (Genebank accession number NM_001525) or Chinese ovary cells (CHO) stably expressing human orexin 1 receptor (Genebank accession number NM_001526) were grown to confluency in DMEM (Hyclone, cat #SH30022), 10% FBS, 1x Pen/Strep, 1x sodium pyruvate, 10 mM HEPES, 600 ug/mL G418 and DMEM/F12 (Gibco, Cat #11039), 10% FBS, 1x Pen/Strep, 600 ug/mL G418 media, respectively on 150 cm^2 tissue culture plates, washed with 5 mM EDTA in PBS (HyClone Dulbecco's Phosphate Buffered Saline 1x with Calcium and Magnesium, Cat #SH30264.01, hereafter referred to simply as PBS) and scraped into 50 ml tubes.

Compounds were solubilized in 100% DMSO (Acros Organics, Cat. #61042-1000) and tested over a range of 7 concentrations (from 0.1 nM to 10 uM). The final concentration of DMSO in the reactions is equal to or less than 0.1%. Total and nonspecific binding was determined in the absence and presence of 10 uM almorexant. The total volume of each reaction is 200 uL (20 uL of diluted compounds, 80 uL of [3H]-(1-(5-(2-fluoro-phenyl)-2-methyl-thiazol-4-yl)-1-((S)-2-(5-phenyl-(1,3,4)oxadiazol-2-ylmethyl)-pyrrolidin-1-yl)-methanone) diluted in PBS and 100 uL of the cell suspension). Reactions were run for 60 min at room temperature and terminated by filtration through GF/C filter plates (PerkinElmer, Cat. #6005174) presoaked in 0.3% polyethylenimine using the cell harvester (PerkinElmer Filtermate). The plates were washed 3 times by aspirating 30 ml PBS through the plates. Plates were dried in 55° C. oven for 60 min, scintillation fluid was added, and the radioactivity was counted on a Topcount (Packard).

After centrifugation (2KxG, 5 min at 4° C.), the supernatant was aspirated and the pellets frozen and stored at -80\°C. Cells were resuspended in PBS in the presence of 1 tablet of protease inhibitor cocktail (Roche, Cat. #11836145001) per 50 mL. Each cell pellet from a 15 cm plate was resuspended in 10 mL, stored on ice, and homogenized for 45 sec prior to addition to the reactions. Competition binding experiments in 96 well polypropylene plates were performed using [3H]-SB674042 (Moraveck Corporation, specific activity=35.3 Ci/mmol), diluted to a 10 nM concentration in PBS (4 nM final). Compounds were solubilized in 100% DMSO (Acros Organics, Cat. #61042-1000) and tested over a range of 7 concentrations (from 0.1 nM to 10 uM). The final concentration of DMSO in the reactions is equal to or less than 0.1%. Total and nonspecific binding was determined in the absence and presence of 10 uM almorexant.

Radioligand Binding Assay: Human Embryonic Kidney 293 cells (HEK293) stably expressing rat orexin 1 receptor (Genebank accession number NM_001525) or Chinese ovary cells (CHO) stably expressing human orexin 1 receptor (Genebank accession number NM_001526) were grown to confluency in DMEM (Hyclone, cat #SH30022), 10% FBS, 1x Pen/Strep, 1x sodium pyruvate, 10 mM HEPES, 600 ug/mL G418 and DMEM/F12 (Gibco, Cat #11039), 10% FBS, 1x Pen/Strep, 600 ug/mL G418 media, respectively on 150 cm^2 tissue culture plates, washed with 5 mM EDTA in PBS (HyClone Dulbecco's Phosphate Buffered Saline 1x with Calcium and Magnesium, Cat #SH30264.01, hereafter referred to simply as PBS) and scraped into 50 ml tubes. After centrifugation (2KxG, 5 min at 4° C.), the supernatant was aspirated and the pellets frozen and stored at -80\°C. Cells were resuspended in PBS in the presence of 1 tablet of protease inhibitor cocktail (Roche, Cat. #11836145001) per 50 mL. Each cell pellet from a 15 cm plate was resuspended in 10 mL, stored on ice, and homogenized for 45 sec prior to addition to the reactions. Competition binding experiments in 96 well polypropylene plates were performed using [3H]-SB674042 (Moraveck Corporation, specific activity=35.3 Ci/mmol), diluted to a 10 nM concentration in PBS (4 nM final). Compounds were solubilized in 100% DMSO (Acros Organics, Cat. #61042-1000) and tested over a range of 7 concentrations (from 0.1 nM to 10 uM). The final concentration of DMSO in the reactions is equal to or less than 0.1%. Total and nonspecific binding was determined in the absence and presence of 10 uM almorexant. The total volume of each reaction is 200 uL (20 uL of diluted compounds, 80 uL of [3H]-(1-(5-(2-fluoro-phenyl)-2-methyl-thiazol-4-yl)-1-((S)-2-(5-phenyl-(1,3,4)oxadiazol-2-ylmethyl)-pyrrolidin-1-yl)-methanone) diluted in PBS and 100 uL of the cell suspension). Reactions were run for 60 min at room temperature and terminated by filtration through GF/C filter plates (PerkinElmer, Cat. #6005174) presoaked in 0.3% polyethylenimine using the cell harvester (PerkinElmer Filtermate).

Radioligand Binding Assay: Human Embryonic Kidney 293 cells (HEK293) stably expressing rat orexin 1 receptor (Genebank accession number NM_001525) or Chinese ovary cells (CHO) stably expressing human orexin 1 receptor (Genebank accession number NM_001526) were grown to confluency in DMEM (Hyclone, cat #SH30022), 10% FBS, 1x Pen/Strep, 1x sodium pyruvate, 10 mM HEPES, 600 ug/mL G418 and DMEM/F12 (Gibco, Cat #11039), 10% FBS, 1x Pen/Strep, 600 ug/mL G418 media, respectively on 150 cm^2 tissue culture plates, washed with 5 mM EDTA in PBS (HyClone Dulbecco's Phosphate Buffered Saline 1x with Calcium and Magnesium, Cat #SH30264.01, hereafter referred to simply as PBS) and scraped into 50 ml tubes. After centrifugation (2KxG, 5 min at 4° C.), the supernatant was aspirated and the pellets frozen and stored at -80\°C. Cells were resuspended in PBS in the presence of 1 tablet of protease inhibitor cocktail (Roche, Cat. #11836145001) per 50 mL. Each cell pellet from a 15 cm plate was resuspended in 10 mL, stored on ice, and homogenized for 45 sec prior to addition to the reactions. Competition binding experiments in 96 well polypropylene plates were performed using [3H]-SB674042 (Moraveck Corporation, specific activity=35.3 Ci/mmol), diluted to a 10 nM concentration in PBS (4 nM final). Compounds were solubilized in 100% DMSO (Acros Organics, Cat. #61042-1000) and tested over a range of 7 concentrations (from 0.1 nM to 10 uM). The final concentration of DMSO in the reactions is equal to or less than 0.1%. Total and nonspecific binding was determined in the absence and presence of 10 uM almorexant. The total volume of each reaction is 200 uL (20 uL of diluted compounds, 80 uL of [3H]-(1-(5-(2-fluoro-phenyl)-2-methyl-thiazol-4-yl)-1-((S)-2-(5-phenyl-(1,3,4)oxadiazol-2-ylmethyl)-pyrrolidin-1-yl)-methanone) diluted in PBS and 100 uL of the cell suspension). Reactions were run for 60 min at room temperature and terminated by filtration through GF/C filter plates (PerkinElmer, Cat. #6005174) presoaked in 0.3% polyethylenimine using the cell harvester (PerkinElmer Filtermate). The plates were washed 3 times by aspirating 30 ml PBS through the plates. Plates were dried in 55° C. oven for 60 min, scintillation fluid was added, and the radioactivity was counted on a Topcount (Packard).Radioligand Binding Assay: Human Embryonic Kidney 293 cells (HEK293) stably expressing rat orexin 1 receptor (Genebank accession number NM_001525) or Chinese ovary cells (CHO) stably expressing human orexin 1 receptor (Genebank accession number NM_001526) were grown to confluency in DMEM (Hyclone, cat #SH30022), 10% FBS, 1x Pen/Strep, 1x sodium pyruvate, 10 mM HEPES, 600 ug/mL G418 and DMEM/F12 (Gibco, Cat #11039), 10% FBS, 1x Pen/Strep, 600 ug/mL G418 media, respectively on 150 cm^2 tissue culture plates, washed with 5 mM EDTA in PBS (HyClone Dulbecco's Phosphate Buffered Saline 1x with Calcium and Magnesium, Cat #SH30264.01, hereafter referred to simply as PBS) and scraped into 50 ml tubes.

After centrifugation (2KxG, 5 min at 4° C.), the supernatant was aspirated and the pellets frozen and stored at -80\°C. Cells were resuspended in PBS in the presence of 1 tablet of protease inhibitor cocktail (Roche, Cat. #11836145001) per 50 mL. Each cell pellet from a 15 cm plate was resuspended in 10 mL, stored on ice, and homogenized for 45 sec prior to addition to the reactions. Competition binding experiments in 96 well polypropylene plates were performed using [3H]-SB674042 (Moraveck Corporation, specific activity=35.3 Ci/mmol), diluted to a 10 nM concentration in PBS (4 nM final). Compounds were solubilized in 100% DMSO (Acros Organics, Cat. #61042-1000) and tested over a range of 7 concentrations (from 0.1 nM to 10 uM). The final concentration of DMSO in the reactions is equal to or less than 0.1%. Total and nonspecific binding was determined in the absence and presence of 10 uM almorexant. The total volume of each reaction is 200 uL (20 uL of diluted compounds, 80 uL of [3H]-(1-(5-(2-fluoro-phenyl)-2-methyl-thiazol-4-yl)-1-((S)-2-(5-phenyl-(1,3,4)oxadiazol-2-ylmethyl)-pyrrolidin-1-yl)-methanone) diluted in PBS and 100 uL of the cell suspension). Reactions were run for 60 min at room temperature and terminated by filtration through GF/C filter plates (PerkinElmer, Cat. #6005174) presoaked in 0.3% polyethylenimine using the cell harvester (PerkinElmer Filtermate). The plates were washed 3 times by aspirating 30 ml PBS through the plates. Plates were dried in 55° C. oven for 60 min, scintillation fluid was added, and the radioactivity was counted on a Topcount (Packard).Radioligand Binding Assay: Human Embryonic Kidney 293 cells (HEK293) stably expressing rat orexin 1 receptor (Genebank accession number NM_001525) or Chinese ovary cells (CHO) stably expressing human orexin 1 receptor (Genebank accession number NM_001526) were grown to confluency in DMEM (Hyclone, cat #SH30022), 10% FBS, 1x Pen/Strep, 1x sodium pyruvate, 10 mM HEPES, 600 ug/mL G418 and DMEM/F12 (Gibco, Cat #11039), 10% FBS, 1x Pen/Strep, 600 ug/mL G418 media, respectively on 150 cm^2 tissue culture plates, washed with 5 mM EDTA in PBS (HyClone Dulbecco's Phosphate Buffered Saline 1x with Calcium and Magnesium, Cat #SH30264.01, hereafter referred to simply as PBS) and scraped into 50 ml tubes.

After centrifugation (2KxG, 5 min at 4° C.), the supernatant was aspirated and the pellets frozen and stored at -80\°C. Cells were resuspended in PBS in the presence of 1 tablet of protease inhibitor cocktail (Roche, Cat. #11836145001) per 50 mL. Each cell pellet from a 15 cm plate was resuspended in 10 mL, stored on ice, and homogenized for 45 sec prior to addition to the reactions. Competition binding experiments in 96 well polypropylene plates were performed using [3H]-SB674042 (Moraveck Corporation, specific activity=35.3 Ci/mmol), diluted to a 10 nM concentration in PBS (4 nM final). Compounds were solubilized in 100% DMSO (Acros Organics, Cat. #61042-1000) and tested over a range of 7 concentrations (from 0.1 nM to 10 uM). The final concentration of DMSO in the reactions is equal to or less than 0.1%. Total and nonspecific binding was determined in the absence and presence of 10 uM almorexant. The total volume of each reaction is 200 uL (20 uL of diluted compounds, 80 uL of [3H]-(1-(5-(2-fluoro-phenyl)-2-methyl-thiazol-4-yl)-1-((S)-2-(5-phenyl-(1,3,4)oxadiazol-2-ylmethyl)-pyrrolidin-1-yl)-methanone) diluted in PBS and 100 uL of the cell suspension). Reactions were run for 60 min at room temperature and terminated by filtration through GF/C filter plates (PerkinElmer, Cat. #6005174) presoaked in 0.3% polyethylenimine using the cell harvester (PerkinElmer Filtermate). The plates were washed 3 times by aspirating 30 ml PBS through the plates. Plates were dried in 55° C. oven for 60 min, scintillation fluid was added, and the radioactivity was counted on a Topcount (Packard).Radioligand Binding Assay: Human Embryonic Kidney 293 cells (HEK293) stably expressing rat orexin 1 receptor (Genebank accession number NM_001525) or Chinese ovary cells (CHO) stably expressing human orexin 1 receptor (Genebank accession number NM_001526) were grown to confluency in DMEM (Hyclone, cat #SH30022), 10% FBS, 1x Pen/Strep, 1x sodium pyruvate, 10 mM HEPES, 600 ug/mL G418 and DMEM/F12 (Gibco, Cat #11039), 10% FBS, 1x Pen/Strep, 600 ug/mL G418 media, respectively on 150 cm^2 tissue culture plates, washed with 5 mM EDTA in PBS (HyClone Dulbecco's Phosphate Buffered Saline 1x with Calcium and Magnesium, Cat #SH30264.01, hereafter referred to simply as PBS) and scraped into 50 ml tubes.

After centrifugation (2KxG, 5 min at 4° C.), the supernatant was aspirated and the pellets frozen and stored at -80\°C. Cells were resuspended in PBS in the presence of 1 tablet of protease inhibitor cocktail (Roche, Cat. #11836145001) per 50 mL. Each cell pellet from a 15 cm plate was resuspended in 10 mL, stored on ice, and homogenized for 45 sec prior to addition to the reactions. Competition binding experiments in 96 well polypropylene plates were performed using [3H]-SB674042 (Moraveck Corporation, specific activity=35.3 Ci/mmol), diluted to a 10 nM concentration in PBS (4 nM final). Compounds were solubilized in 100% DMSO (Acros Organics, Cat. #61042-1000) and tested over a range of 7 concentrations (from 0.1 nM to 10 uM). The final concentration of DMSO in the reactions is equal to or less than 0.1%. Total and nonspecific binding was determined in the absence and presence of 10 uM almorexant. The total volume of each reaction is 200 uL (20 uL of diluted compounds, 80 uL of [3H]-(1-(5-(2-fluoro-phenyl)-2-methyl-thiazol-4-yl)-1-((S)-2-(5-phenyl-(1,3,4)oxadiazol-2-ylmethyl)-pyrrolidin-1-yl)-methanone) diluted in PBS and 100 uL of the cell suspension).

Radioligand Binding Assay: Human Embryonic Kidney 293 cells (HEK293) stably expressing rat orexin 1 receptor (Genebank accession number NM_001525) or Chinese ovary cells (CHO) stably expressing human orexin 1 receptor (Genebank accession number NM_001526) were grown to confluency in DMEM (Hyclone, cat #SH30022), 10% FBS, 1x Pen/Strep, 1x sodium pyruvate, 10 mM HEPES, 600 ug/mL G418 and DMEM/F12 (Gibco, Cat #11039), 10% FBS, 1x Pen/Strep, 600 ug/mL G418 media, respectively on 150 cm^2 tissue culture plates, washed with 5 mM EDTA in PBS (HyClone Dulbecco's Phosphate Buffered Saline 1x with Calcium and Magnesium, Cat #SH30264.01, hereafter referred to simply as PBS) and scraped into 50 ml tubes. After centrifugation (2KxG, 5 min at 4° C.), the supernatant was aspirated and the pellets frozen and stored at -80\°C. Cells were resuspended in PBS in the presence of 1 tablet of protease inhibitor cocktail (Roche, Cat. #11836145001) per 50 mL. Each cell pellet from a 15 cm plate was resuspended in 10 mL, stored on ice, and homogenized for 45 sec prior to addition to the reactions. Competition binding experiments in 96 well polypropylene plates were performed using [3H]-SB674042 (Moraveck Corporation, specific activity=35.3 Ci/mmol), diluted to a 10 nM concentration in PBS (4 nM final). Compounds were solubilized in 100% DMSO (Acros Organics, Cat. #61042-1000) and tested over a range of 7 concentrations (from 0.1 nM to 10 uM). The final concentration of DMSO in the reactions is equal to or less than 0.1%. Total and nonspecific binding was determined in the absence and presence of 10 uM almorexant. The total volume of each reaction is 200 uL (20 uL of diluted compounds, 80 uL of [3H]-(1-(5-(2-fluoro-phenyl)-2-methyl-thiazol-4-yl)-1-((S)-2-(5-phenyl-(1,3,4)oxadiazol-2-ylmethyl)-pyrrolidin-1-yl)-methanone) diluted in PBS and 100 uL of the cell suspension). Reactions were run for 60 min at room temperature and terminated by filtration through GF/C filter plates (PerkinElmer, Cat. #6005174) presoaked in 0.3% polyethylenimine using the cell harvester (PerkinElmer Filtermate). The plates were washed 3 times by aspirating 30 ml PBS through the plates. Plates were dried in 55° C. oven for 60 min, scintillation fluid was added, and the radioactivity was counted on a Topcount (Packard).Radioligand Binding Assay: Human Embryonic Kidney 293 cells (HEK293) stably expressing rat orexin 1 receptor (Genebank accession number NM_001525) or Chinese ovary cells (CHO) stably expressing human orexin 1 receptor (Genebank accession number NM_001526) were grown to confluency in DMEM (Hyclone, cat #SH30022), 10% FBS, 1x Pen/Strep, 1x sodium pyruvate, 10 mM HEPES, 600 ug/mL G418 and DMEM/F12 (Gibco, Cat #11039), 10% FBS, 1x Pen/Strep, 600 ug/mL G418 media, respectively on 150 cm^2 tissue culture plates, washed with 5 mM EDTA in PBS (HyClone Dulbecco's Phosphate Buffered Saline 1x with Calcium and Magnesium, Cat #SH30264.01, hereafter referred to simply as PBS) and scraped into 50 ml tubes.

Radioligand Binding Assay: Human Embryonic Kidney 293 cells (HEK293) stably expressing rat orexin 1 receptor (Genebank accession number NM_001525) or Chinese ovary cells (CHO) stably expressing human orexin 1 receptor (Genebank accession number NM_001526) were grown to confluency in DMEM (Hyclone, cat #SH30022), 10% FBS, 1x Pen/Strep, 1x sodium pyruvate, 10 mM HEPES, 600 ug/mL G418 and DMEM/F12 (Gibco, Cat #11039), 10% FBS, 1x Pen/Strep, 600 ug/mL G418 media, respectively on 150 cm^2 tissue culture plates, washed with 5 mM EDTA in PBS (HyClone Dulbecco's Phosphate Buffered Saline 1x with Calcium and Magnesium, Cat #SH30264.01, hereafter referred to simply as PBS) and scraped into 50 ml tubes. After centrifugation (2KxG, 5 min at 4° C.), the supernatant was aspirated and the pellets frozen and stored at -80\°C. Cells were resuspended in PBS in the presence of 1 tablet of protease inhibitor cocktail (Roche, Cat. #11836145001) per 50 mL. Each cell pellet from a 15 cm plate was resuspended in 10 mL, stored on ice, and homogenized for 45 sec prior to addition to the reactions. Competition binding experiments in 96 well polypropylene plates were performed using [3H]-SB674042 (Moraveck Corporation, specific activity=35.3 Ci/mmol), diluted to a 10 nM concentration in PBS (4 nM final). Compounds were solubilized in 100% DMSO (Acros Organics, Cat. #61042-1000) and tested over a range of 7 concentrations (from 0.1 nM to 10 uM). The final concentration of DMSO in the reactions is equal to or less than 0.1%. Total and nonspecific binding was determined in the absence and presence of 10 uM almorexant. The total volume of each reaction is 200 uL (20 uL of diluted compounds, 80 uL of [3H]-(1-(5-(2-fluoro-phenyl)-2-methyl-thiazol-4-yl)-1-((S)-2-(5-phenyl-(1,3,4)oxadiazol-2-ylmethyl)-pyrrolidin-1-yl)-methanone) diluted in PBS and 100 uL of the cell suspension). Reactions were run for 60 min at room temperature and terminated by filtration through GF/C filter plates (PerkinElmer, Cat. #6005174) presoaked in 0.3% polyethylenimine using the cell harvester (PerkinElmer Filtermate). The plates were washed 3 times by aspirating 30 ml PBS through the plates. Plates were dried in 55° C. oven for 60 min, scintillation fluid was added, and the radioactivity was counted on a Topcount (Packard).Radioligand Binding Assay: Human Embryonic Kidney 293 cells (HEK293) stably expressing rat orexin 1 receptor (Genebank accession number NM_001525) or Chinese ovary cells (CHO) stably expressing human orexin 1 receptor (Genebank accession number NM_001526) were grown to confluency in DMEM (Hyclone, cat #SH30022), 10% FBS, 1x Pen/Strep, 1x sodium pyruvate, 10 mM HEPES, 600 ug/mL G418 and DMEM/F12 (Gibco, Cat #11039), 10% FBS, 1x Pen/Strep, 600 ug/mL G418 media, respectively on 150 cm^2 tissue culture plates, washed with 5 mM EDTA in PBS (HyClone Dulbecco's Phosphate Buffered Saline 1x with Calcium and Magnesium, Cat #SH30264.01, hereafter referred to simply as PBS) and scraped into 50 ml tubes.

Cells were resuspended in PBS in the presence of 1 tablet of protease inhibitor cocktail (Roche, Cat. #11836145001) per 50 mL. Each cell pellet from a 15 cm plate was resuspended in 10 mL, stored on ice, and homogenized for 45 sec prior to addition to the reactions. Competition binding experiments in 96 well polypropylene plates were performed using [3H]-SB674042 (Moraveck Corporation, specific activity=35.3 Ci/mmol), diluted to a 10 nM concentration in PBS (4 nM final). Compounds were solubilized in 100% DMSO (Acros Organics, Cat. #61042-1000) and tested over a range of 7 concentrations (from 0.1 nM to 10 uM). The final concentration of DMSO in the reactions is equal to or less than 0.1%. Total and nonspecific binding was determined in the absence and presence of 10 uM almorexant. The total volume of each reaction is 200 uL (20 uL of diluted compounds, 80 uL of [3H]-(1-(5-(2-fluoro-phenyl)-2-methyl-thiazol-4-yl)-1-((S)-2-(5-phenyl-(1,3,4)oxadiazol-2-ylmethyl)-pyrrolidin-1-yl)-methanone) diluted in PBS and 100 uL of the cell suspension). Reactions were run for 60 min at room temperature and terminated by filtration through GF/C filter plates (PerkinElmer, Cat. #6005174) presoaked in 0.3% polyethylenimine using the cell harvester (PerkinElmer Filtermate). The plates were washed 3 times by aspirating 30 ml PBS through the plates.

After centrifugation (2KxG, 5 min at 4° C.), the supernatant was aspirated and the pellets frozen and stored at -80\°C. Cells were resuspended in PBS in the presence of 1 tablet of protease inhibitor cocktail (Roche, Cat. #11836145001) per 50 mL. Each cell pellet from a 15 cm plate was resuspended in 10 mL, stored on ice, and homogenized for 45 sec prior to addition to the reactions. Competition binding experiments in 96 well polypropylene plates were performed using [3H]-SB674042 (Moraveck Corporation, specific activity=35.3 Ci/mmol), diluted to a 10 nM concentration in PBS (4 nM final). Compounds were solubilized in 100% DMSO (Acros Organics, Cat. #61042-1000) and tested over a range of 7 concentrations (from 0.1 nM to 10 uM). The final concentration of DMSO in the reactions is equal to or less than 0.1%. Total and nonspecific binding was determined in the absence and presence of 10 uM almorexant. The total volume of each reaction is 200 uL (20 uL of diluted compounds, 80 uL of [3H]-(1-(5-(2-fluoro-phenyl)-2-methyl-thiazol-4-yl)-1-((S)-2-(5-phenyl-(1,3,4)oxadiazol-2-ylmethyl)-pyrrolidin-1-yl)-methanone) diluted in PBS and 100 uL of the cell suspension).

The final concentration of DMSO in the reactions is equal to or less than 0.1%. Total and nonspecific binding was determined in the absence and presence of 10 uM almorexant. The total volume of each reaction is 200 uL (20 uL of diluted compounds, 80 uL of [3H]-(1-(5-(2-fluoro-phenyl)-2-methyl-thiazol-4-yl)-1-((S)-2-(5-phenyl-(1,3,4)oxadiazol-2-ylmethyl)-pyrrolidin-1-yl)-methanone) diluted in PBS and 100 uL of the cell suspension). Reactions were run for 60 min at room temperature and terminated by filtration through GF/C filter plates (PerkinElmer, Cat. #6005174) presoaked in 0.3% polyethylenimine using the cell harvester (PerkinElmer Filtermate). The plates were washed 3 times by aspirating 30 ml PBS through the plates. Plates were dried in 55° C. oven for 60 min, scintillation fluid was added, and the radioactivity was counted on a Topcount (Packard).

Each cell pellet from a 15 cm plate was resuspended in 10 mL, stored on ice, and homogenized for 45 sec prior to addition to the reactions. Competition binding experiments in 96 well polypropylene plates were performed using [3H]-SB674042 (Moraveck Corporation, specific activity=35.3 Ci/mmol), diluted to a 10 nM concentration in PBS (4 nM final). Compounds were solubilized in 100% DMSO (Acros Organics, Cat. #61042-1000) and tested over a range of 7 concentrations (from 0.1 nM to 10 uM). The final concentration of DMSO in the reactions is equal to or less than 0.1%. Total and nonspecific binding was determined in the absence and presence of 10 uM almorexant. The total volume of each reaction is 200 uL (20 uL of diluted compounds, 80 uL of [3H]-(1-(5-(2-fluoro-phenyl)-2-methyl-thiazol-4-yl)-1-((S)-2-(5-phenyl-(1,3,4)oxadiazol-2-ylmethyl)-pyrrolidin-1-yl)-methanone) diluted in PBS and 100 uL of the cell suspension). Reactions were run for 60 min at room temperature and terminated by filtration through GF/C filter plates (PerkinElmer, Cat. #6005174) presoaked in 0.3% polyethylenimine using the cell harvester (PerkinElmer Filtermate). The plates were washed 3 times by aspirating 30 ml PBS through the plates. Plates were dried in 55° C. oven for 60 min, scintillation fluid was added, and the radioactivity was counted on a Topcount (Packard).

Radioligand Binding Assay: Human Embryonic Kidney 293 cells (HEK293) stably expressing rat orexin 1 receptor (Genebank accession number NM_001525) or Chinese ovary cells (CHO) stably expressing human orexin 1 receptor (Genebank accession number NM_001526) were grown to confluency in DMEM (Hyclone, cat #SH30022), 10% FBS, 1x Pen/Strep, 1x sodium pyruvate, 10 mM HEPES, 600 ug/mL G418 and DMEM/F12 (Gibco, Cat #11039), 10% FBS, 1x Pen/Strep, 600 ug/mL G418 media, respectively on 150 cm^2 tissue culture plates, washed with 5 mM EDTA in PBS (HyClone Dulbecco's Phosphate Buffered Saline 1x with Calcium and Magnesium, Cat #SH30264.01, hereafter referred to simply as PBS) and scraped into 50 ml tubes. After centrifugation (2KxG, 5 min at 4° C.), the supernatant was aspirated and the pellets frozen and stored at -80\°C. Cells were resuspended in PBS in the presence of 1 tablet of protease inhibitor cocktail (Roche, Cat. #11836145001) per 50 mL. Each cell pellet from a 15 cm plate was resuspended in 10 mL, stored on ice, and homogenized for 45 sec prior to addition to the reactions. Competition binding experiments in 96 well polypropylene plates were performed using [3H]-SB674042 (Moraveck Corporation, specific activity=35.3 Ci/mmol), diluted to a 10 nM concentration in PBS (4 nM final). Compounds were solubilized in 100% DMSO (Acros Organics, Cat. #61042-1000) and tested over a range of 7 concentrations (from 0.1 nM to 10 uM). The final concentration of DMSO in the reactions is equal to or less than 0.1%. Total and nonspecific binding was determined in the absence and presence of 10 uM almorexant. The total volume of each reaction is 200 uL (20 uL of diluted compounds, 80 uL of [3H]-(1-(5-(2-fluoro-phenyl)-2-methyl-thiazol-4-yl)-1-((S)-2-(5-phenyl-(1,3,4)oxadiazol-2-ylmethyl)-pyrrolidin-1-yl)-methanone) diluted in PBS and 100 uL of the cell suspension). Reactions were run for 60 min at room temperature and terminated by filtration through GF/C filter plates (PerkinElmer, Cat. #6005174) presoaked in 0.3% polyethylenimine using the cell harvester (PerkinElmer Filtermate). The plates were washed 3 times by aspirating 30 ml PBS through the plates. Plates were dried in 55° C. oven for 60 min, scintillation fluid was added, and the radioactivity was counted on a Topcount (Packard).Radioligand Binding Assay: Human Embryonic Kidney 293 cells (HEK293) stably expressing rat orexin 1 receptor (Genebank accession number NM_001525) or Chinese ovary cells (CHO) stably expressing human orexin 1 receptor (Genebank accession number NM_001526) were grown to confluency in DMEM (Hyclone, cat #SH30022), 10% FBS, 1x Pen/Strep, 1x sodium pyruvate, 10 mM HEPES, 600 ug/mL G418 and DMEM/F12 (Gibco, Cat #11039), 10% FBS, 1x Pen/Strep, 600 ug/mL G418 media, respectively on 150 cm^2 tissue culture plates, washed with 5 mM EDTA in PBS (HyClone Dulbecco's Phosphate Buffered Saline 1x with Calcium and Magnesium, Cat #SH30264.01, hereafter referred to simply as PBS) and scraped into 50 ml tubes.

Radioligand Binding Assay: Human Embryonic Kidney 293 cells (HEK293) stably expressing rat orexin 1 receptor (Genebank accession number NM_001525) or Chinese ovary cells (CHO) stably expressing human orexin 1 receptor (Genebank accession number NM_001526) were grown to confluency in DMEM (Hyclone, cat #SH30022), 10% FBS, 1x Pen/Strep, 1x sodium pyruvate, 10 mM HEPES, 600 ug/mL G418 and DMEM/F12 (Gibco, Cat #11039), 10% FBS, 1x Pen/Strep, 600 ug/mL G418 media, respectively on 150 cm^2 tissue culture plates, washed with 5 mM EDTA in PBS (HyClone Dulbecco's Phosphate Buffered Saline 1x with Calcium and Magnesium, Cat #SH30264.01, hereafter referred to simply as PBS) and scraped into 50 ml tubes. After centrifugation (2KxG, 5 min at 4° C.), the supernatant was aspirated and the pellets frozen and stored at -80\°C. Cells were resuspended in PBS in the presence of 1 tablet of protease inhibitor cocktail (Roche, Cat. #11836145001) per 50 mL. Each cell pellet from a 15 cm plate was resuspended in 10 mL, stored on ice, and homogenized for 45 sec prior to addition to the reactions. Competition binding experiments in 96 well polypropylene plates were performed using [3H]-SB674042 (Moraveck Corporation, specific activity=35.3 Ci/mmol), diluted to a 10 nM concentration in PBS (4 nM final). Compounds were solubilized in 100% DMSO (Acros Organics, Cat. #61042-1000) and tested over a range of 7 concentrations (from 0.1 nM to 10 uM). The final concentration of DMSO in the reactions is equal to or less than 0.1%. Total and nonspecific binding was determined in the absence and presence of 10 uM almorexant. The total volume of each reaction is 200 uL (20 uL of diluted compounds, 80 uL of [3H]-(1-(5-(2-fluoro-phenyl)-2-methyl-thiazol-4-yl)-1-((S)-2-(5-phenyl-(1,3,4)oxadiazol-2-ylmethyl)-pyrrolidin-1-yl)-methanone) diluted in PBS and 100 uL of the cell suspension).

Cells were resuspended in PBS in the presence of 1 tablet of protease inhibitor cocktail (Roche, Cat. #11836145001) per 50 mL. Each cell pellet from a 15 cm plate was resuspended in 10 mL, stored on ice, and homogenized for 45 sec prior to addition to the reactions. Competition binding experiments in 96 well polypropylene plates were performed using [3H]-SB674042 (Moraveck Corporation, specific activity=35.3 Ci/mmol), diluted to a 10 nM concentration in PBS (4 nM final). Compounds were solubilized in 100% DMSO (Acros Organics, Cat. #61042-1000) and tested over a range of 7 concentrations (from 0.1 nM to 10 uM). The final concentration of DMSO in the reactions is equal to or less than 0.1%. Total and nonspecific binding was determined in the absence and presence of 10 uM almorexant. The total volume of each reaction is 200 uL (20 uL of diluted compounds, 80 uL of [3H]-(1-(5-(2-fluoro-phenyl)-2-methyl-thiazol-4-yl)-1-((S)-2-(5-phenyl-(1,3,4)oxadiazol-2-ylmethyl)-pyrrolidin-1-yl)-methanone) diluted in PBS and 100 uL of the cell suspension). Reactions were run for 60 min at room temperature and terminated by filtration through GF/C filter plates (PerkinElmer, Cat. #6005174) presoaked in 0.3% polyethylenimine using the cell harvester (PerkinElmer Filtermate). The plates were washed 3 times by aspirating 30 ml PBS through the plates. Plates were dried in 55° C. oven for 60 min, scintillation fluid was added, and the radioactivity was counted on a Topcount (Packard).Radioligand Binding Assay: Human Embryonic Kidney 293 cells (HEK293) stably expressing rat orexin 1 receptor (Genebank accession number NM_001525) or Chinese ovary cells (CHO) stably expressing human orexin 1 receptor (Genebank accession number NM_001526) were grown to confluency in DMEM (Hyclone, cat #SH30022), 10% FBS, 1x Pen/Strep, 1x sodium pyruvate, 10 mM HEPES, 600 ug/mL G418 and DMEM/F12 (Gibco, Cat #11039), 10% FBS, 1x Pen/Strep, 600 ug/mL G418 media, respectively on 150 cm^2 tissue culture plates, washed with 5 mM EDTA in PBS (HyClone Dulbecco's Phosphate Buffered Saline 1x with Calcium and Magnesium, Cat #SH30264.01, hereafter referred to simply as PBS) and scraped into 50 ml tubes.

After centrifugation (2KxG, 5 min at 4° C.), the supernatant was aspirated and the pellets frozen and stored at -80\°C. Cells were resuspended in PBS in the presence of 1 tablet of protease inhibitor cocktail (Roche, Cat. #11836145001) per 50 mL. Each cell pellet from a 15 cm plate was resuspended in 10 mL, stored on ice, and homogenized for 45 sec prior to addition to the reactions. Competition binding experiments in 96 well polypropylene plates were performed using [3H]-SB674042 (Moraveck Corporation, specific activity=35.3 Ci/mmol), diluted to a 10 nM concentration in PBS (4 nM final). Compounds were solubilized in 100% DMSO (Acros Organics, Cat. #61042-1000) and tested over a range of 7 concentrations (from 0.1 nM to 10 uM). The final concentration of DMSO in the reactions is equal to or less than 0.1%. Total and nonspecific binding was determined in the absence and presence of 10 uM almorexant. The total volume of each reaction is 200 uL (20 uL of diluted compounds, 80 uL of [3H]-(1-(5-(2-fluoro-phenyl)-2-methyl-thiazol-4-yl)-1-((S)-2-(5-phenyl-(1,3,4)oxadiazol-2-ylmethyl)-pyrrolidin-1-yl)-methanone) diluted in PBS and 100 uL of the cell suspension). Reactions were run for 60 min at room temperature and terminated by filtration through GF/C filter plates (PerkinElmer, Cat. #6005174) presoaked in 0.3% polyethylenimine using the cell harvester (PerkinElmer Filtermate). The plates were washed 3 times by aspirating 30 ml PBS through the plates. Plates were dried in 55° C. oven for 60 min, scintillation fluid was added, and the radioactivity was counted on a Topcount (Packard).Radioligand Binding Assay: Human Embryonic Kidney 293 cells (HEK293) stably expressing rat orexin 1 receptor (Genebank accession number NM_001525) or Chinese ovary cells (CHO) stably expressing human orexin 1 receptor (Genebank accession number NM_001526) were grown to confluency in DMEM (Hyclone, cat #SH30022), 10% FBS, 1x Pen/Strep, 1x sodium pyruvate, 10 mM HEPES, 600 ug/mL G418 and DMEM/F12 (Gibco, Cat #11039), 10% FBS, 1x Pen/Strep, 600 ug/mL G418 media, respectively on 150 cm^2 tissue culture plates, washed with 5 mM EDTA in PBS (HyClone Dulbecco's Phosphate Buffered Saline 1x with Calcium and Magnesium, Cat #SH30264.01, hereafter referred to simply as PBS) and scraped into 50 ml tubes.

The total volume of each reaction is 200 uL (20 uL of diluted compounds, 80 uL of [3H]-(1-(5-(2-fluoro-phenyl)-2-methyl-thiazol-4-yl)-1-((S)-2-(5-phenyl-(1,3,4)oxadiazol-2-ylmethyl)-pyrrolidin-1-yl)-methanone) diluted in PBS and 100 uL of the cell suspension). Reactions were run for 60 min at room temperature and terminated by filtration through GF/C filter plates (PerkinElmer, Cat. #6005174) presoaked in 0.3% polyethylenimine using the cell harvester (PerkinElmer Filtermate). The plates were washed 3 times by aspirating 30 ml PBS through the plates. Plates were dried in 55° C. oven for 60 min, scintillation fluid was added, and the radioactivity was counted on a Topcount (Packard).

Cells were resuspended in PBS in the presence of 1 tablet of protease inhibitor cocktail (Roche, Cat. #11836145001) per 50 mL. Each cell pellet from a 15 cm plate was resuspended in 10 mL, stored on ice, and homogenized for 45 sec prior to addition to the reactions. Competition binding experiments in 96 well polypropylene plates were performed using [3H]-SB674042 (Moraveck Corporation, specific activity=35.3 Ci/mmol), diluted to a 10 nM concentration in PBS (4 nM final). Compounds were solubilized in 100% DMSO (Acros Organics, Cat. #61042-1000) and tested over a range of 7 concentrations (from 0.1 nM to 10 uM). The final concentration of DMSO in the reactions is equal to or less than 0.1%. Total and nonspecific binding was determined in the absence and presence of 10 uM almorexant. The total volume of each reaction is 200 uL (20 uL of diluted compounds, 80 uL of [3H]-(1-(5-(2-fluoro-phenyl)-2-methyl-thiazol-4-yl)-1-((S)-2-(5-phenyl-(1,3,4)oxadiazol-2-ylmethyl)-pyrrolidin-1-yl)-methanone) diluted in PBS and 100 uL of the cell suspension). Reactions were run for 60 min at room temperature and terminated by filtration through GF/C filter plates (PerkinElmer, Cat. #6005174) presoaked in 0.3% polyethylenimine using the cell harvester (PerkinElmer Filtermate). The plates were washed 3 times by aspirating 30 ml PBS through the plates. Plates were dried in 55° C. oven for 60 min, scintillation fluid was added, and the radioactivity was counted on a Topcount (Packard).

Compounds were solubilized in 100% DMSO (Acros Organics, Cat. #61042-1000) and tested over a range of 7 concentrations (from 0.1 nM to 10 uM). The final concentration of DMSO in the reactions is equal to or less than 0.1%. Total and nonspecific binding was determined in the absence and presence of 10 uM almorexant. The total volume of each reaction is 200 uL (20 uL of diluted compounds, 80 uL of [3H]-(1-(5-(2-fluoro-phenyl)-2-methyl-thiazol-4-yl)-1-((S)-2-(5-phenyl-(1,3,4)oxadiazol-2-ylmethyl)-pyrrolidin-1-yl)-methanone) diluted in PBS and 100 uL of the cell suspension). Reactions were run for 60 min at room temperature and terminated by filtration through GF/C filter plates (PerkinElmer, Cat. #6005174) presoaked in 0.3% polyethylenimine using the cell harvester (PerkinElmer Filtermate). The plates were washed 3 times by aspirating 30 ml PBS through the plates. Plates were dried in 55° C. oven for 60 min, scintillation fluid was added, and the radioactivity was counted on a Topcount (Packard).

Reactions were run for 60 min at room temperature and terminated by filtration through GF/C filter plates (PerkinElmer, Cat. #6005174) presoaked in 0.3% polyethylenimine using the cell harvester (PerkinElmer Filtermate). The plates were washed 3 times by aspirating 30 ml PBS through the plates. Plates were dried in 55° C. oven for 60 min, scintillation fluid was added, and the radioactivity was counted on a Topcount (Packard).Radioligand Binding Assay: Human Embryonic Kidney 293 cells (HEK293) stably expressing rat orexin 1 receptor (Genebank accession number NM_001525) or Chinese ovary cells (CHO) stably expressing human orexin 1 receptor (Genebank accession number NM_001526) were grown to confluency in DMEM (Hyclone, cat #SH30022), 10% FBS, 1x Pen/Strep, 1x sodium pyruvate, 10 mM HEPES, 600 ug/mL G418 and DMEM/F12 (Gibco, Cat #11039), 10% FBS, 1x Pen/Strep, 600 ug/mL G418 media, respectively on 150 cm^2 tissue culture plates, washed with 5 mM EDTA in PBS (HyClone Dulbecco's Phosphate Buffered Saline 1x with Calcium and Magnesium, Cat #SH30264.01, hereafter referred to simply as PBS) and scraped into 50 ml tubes. After centrifugation (2KxG, 5 min at 4° C.), the supernatant was aspirated and the pellets frozen and stored at -80\°C. Cells were resuspended in PBS in the presence of 1 tablet of protease inhibitor cocktail (Roche, Cat. #11836145001) per 50 mL. Each cell pellet from a 15 cm plate was resuspended in 10 mL, stored on ice, and homogenized for 45 sec prior to addition to the reactions. Competition binding experiments in 96 well polypropylene plates were performed using [3H]-SB674042 (Moraveck Corporation, specific activity=35.3 Ci/mmol), diluted to a 10 nM concentration in PBS (4 nM final). Compounds were solubilized in 100% DMSO (Acros Organics, Cat. #61042-1000) and tested over a range of 7 concentrations (from 0.1 nM to 10 uM). The final concentration of DMSO in the reactions is equal to or less than 0.1%. Total and nonspecific binding was determined in the absence and presence of 10 uM almorexant. The total volume of each reaction is 200 uL (20 uL of diluted compounds, 80 uL of [3H]-(1-(5-(2-fluoro-phenyl)-2-methyl-thiazol-4-yl)-1-((S)-2-(5-phenyl-(1,3,4)oxadiazol-2-ylmethyl)-pyrrolidin-1-yl)-methanone) diluted in PBS and 100 uL of the cell suspension).

After centrifugation (2KxG, 5 min at 4° C.), the supernatant was aspirated and the pellets frozen and stored at -80\°C. Cells were resuspended in PBS in the presence of 1 tablet of protease inhibitor cocktail (Roche, Cat. #11836145001) per 50 mL. Each cell pellet from a 15 cm plate was resuspended in 10 mL, stored on ice, and homogenized for 45 sec prior to addition to the reactions. Competition binding experiments in 96 well polypropylene plates were performed using [3H]-SB674042 (Moraveck Corporation, specific activity=35.3 Ci/mmol), diluted to a 10 nM concentration in PBS (4 nM final). Compounds were solubilized in 100% DMSO (Acros Organics, Cat. #61042-1000) and tested over a range of 7 concentrations (from 0.1 nM to 10 uM). The final concentration of DMSO in the reactions is equal to or less than 0.1%. Total and nonspecific binding was determined in the absence and presence of 10 uM almorexant. The total volume of each reaction is 200 uL (20 uL of diluted compounds, 80 uL of [3H]-(1-(5-(2-fluoro-phenyl)-2-methyl-thiazol-4-yl)-1-((S)-2-(5-phenyl-(1,3,4)oxadiazol-2-ylmethyl)-pyrrolidin-1-yl)-methanone) diluted in PBS and 100 uL of the cell suspension). Reactions were run for 60 min at room temperature and terminated by filtration through GF/C filter plates (PerkinElmer, Cat. #6005174) presoaked in 0.3% polyethylenimine using the cell harvester (PerkinElmer Filtermate). The plates were washed 3 times by aspirating 30 ml PBS through the plates. Plates were dried in 55° C. oven for 60 min, scintillation fluid was added, and the radioactivity was counted on a Topcount (Packard).
