From these cells, after 48 hours, a membrane preparation was produced by standard methods, aliquoted into 10 mM Tris-HCl; 0.3 mM EDTA; 1 mM EGTA; 250 mM sucrose pH 7.5, and stored at -80 C.The substances were preincubated with the membrane at room temperature for 15 minutes, then the radioligand (ALA-(para-F-Phe)-Arg-ChA-homoArg-(3,4-3H-Tyr)-NH2; approx. 40 Ci/mMol) was added. The end concentration of the radioligand in the test buffer (50 mM Tris-HCl; 10 mM MgCl2; 1 mM EGTA; 0.1% BSA; 2% DMSO) was 20 nM, that of the membrane 1 mg/ml. After an incubation time of 60 minutes, 25 uL of the mixture were transferred to a 96-well MultiScreenHTS FB.

Binding Assay: The synthesized substances were examined in a PAR1 binding test. This tested whether the substances can inhibit the binding of a radioactively labeled PAR1 agonist known from the literature at the PAR1 receptor (Ho-Sam Ahn, Mol Pharm, 51:350-356, 1997). The human PAR1 receptor was expressed transiently in High Five insect cells. From these cells, after 48 hours, a membrane preparation was produced by standard methods, aliquoted into 10 mM Tris-HCl; 0.3 mM EDTA; 1 mM EGTA; 250 mM sucrose pH 7.5, and stored at -80 C.The substances were preincubated with the membrane at room temperature for 15 minutes, then the radioligand (ALA-(para-F-Phe)-Arg-ChA-homoArg-(3,4-3H-Tyr)-NH2; approx. 40 Ci/mMol) was added. The end concentration of the radioligand in the test buffer (50 mM Tris-HCl; 10 mM MgCl2; 1 mM EGTA; 0.1% BSA; 2% DMSO) was 20 nM, that of the membrane 1 mg/ml. After an incubation time of 60 minutes, 25 uL of the mixture were transferred to a 96-well MultiScreenHTS FB.Binding Assay: The synthesized substances were examined in a PAR1 binding test.

Binding Assay: The synthesized substances were examined in a PAR1 binding test. This tested whether the substances can inhibit the binding of a radioactively labeled PAR1 agonist known from the literature at the PAR1 receptor (Ho-Sam Ahn, Mol Pharm, 51:350-356, 1997). The human PAR1 receptor was expressed transiently in High Five insect cells. From these cells, after 48 hours, a membrane preparation was produced by standard methods, aliquoted into 10 mM Tris-HCl; 0.3 mM EDTA; 1 mM EGTA; 250 mM sucrose pH 7.5, and stored at -80 C.The substances were preincubated with the membrane at room temperature for 15 minutes, then the radioligand (ALA-(para-F-Phe)-Arg-ChA-homoArg-(3,4-3H-Tyr)-NH2; approx. 40 Ci/mMol) was added. The end concentration of the radioligand in the test buffer (50 mM Tris-HCl; 10 mM MgCl2; 1 mM EGTA; 0.1% BSA; 2% DMSO) was 20 nM, that of the membrane 1 mg/ml.

Binding Assay: The synthesized substances were examined in a PAR1 binding test. This tested whether the substances can inhibit the binding of a radioactively labeled PAR1 agonist known from the literature at the PAR1 receptor (Ho-Sam Ahn, Mol Pharm, 51:350-356, 1997). The human PAR1 receptor was expressed transiently in High Five insect cells. From these cells, after 48 hours, a membrane preparation was produced by standard methods, aliquoted into 10 mM Tris-HCl; 0.3 mM EDTA; 1 mM EGTA; 250 mM sucrose pH 7.5, and stored at -80 C.The substances were preincubated with the membrane at room temperature for 15 minutes, then the radioligand (ALA-(para-F-Phe)-Arg-ChA-homoArg-(3,4-3H-Tyr)-NH2; approx. 40 Ci/mMol) was added. The end concentration of the radioligand in the test buffer (50 mM Tris-HCl; 10 mM MgCl2; 1 mM EGTA; 0.1% BSA; 2% DMSO) was 20 nM, that of the membrane 1 mg/ml. After an incubation time of 60 minutes, 25 uL of the mixture were transferred to a 96-well MultiScreenHTS FB.Binding Assay: The synthesized substances were examined in a PAR1 binding test.

Binding Assay: The synthesized substances were examined in a PAR1 binding test. This tested whether the substances can inhibit the binding of a radioactively labeled PAR1 agonist known from the literature at the PAR1 receptor (Ho-Sam Ahn, Mol Pharm, 51:350-356, 1997). The human PAR1 receptor was expressed transiently in High Five insect cells. From these cells, after 48 hours, a membrane preparation was produced by standard methods, aliquoted into 10 mM Tris-HCl; 0.3 mM EDTA; 1 mM EGTA; 250 mM sucrose pH 7.5, and stored at -80 C.The substances were preincubated with the membrane at room temperature for 15 minutes, then the radioligand (ALA-(para-F-Phe)-Arg-ChA-homoArg-(3,4-3H-Tyr)-NH2; approx. 40 Ci/mMol) was added. The end concentration of the radioligand in the test buffer (50 mM Tris-HCl; 10 mM MgCl2; 1 mM EGTA; 0.1% BSA; 2% DMSO) was 20 nM, that of the membrane 1 mg/ml.

Binding Assay: The synthesized substances were examined in a PAR1 binding test. This tested whether the substances can inhibit the binding of a radioactively labeled PAR1 agonist known from the literature at the PAR1 receptor (Ho-Sam Ahn, Mol Pharm, 51:350-356, 1997). The human PAR1 receptor was expressed transiently in High Five insect cells. From these cells, after 48 hours, a membrane preparation was produced by standard methods, aliquoted into 10 mM Tris-HCl; 0.3 mM EDTA; 1 mM EGTA; 250 mM sucrose pH 7.5, and stored at -80 C.The substances were preincubated with the membrane at room temperature for 15 minutes, then the radioligand (ALA-(para-F-Phe)-Arg-ChA-homoArg-(3,4-3H-Tyr)-NH2; approx. 40 Ci/mMol) was added. The end concentration of the radioligand in the test buffer (50 mM Tris-HCl; 10 mM MgCl2; 1 mM EGTA; 0.1% BSA; 2% DMSO) was 20 nM, that of the membrane 1 mg/ml.

High Throughput Thrombin Receptor Radioligand Binding Assay: Thrombin receptor antagonists were screened using a modification of the thrombin receptor radioligand binding assay of Ahn et al. (Ahn et al., Mol. Pharmacol., 51:350-356 (1997)). The assay was performed in 96 well Nunc plates (Cat. No. 269620) at a final assay volume of 200 μl. Platelet membranes and [3H]haTRAP were diluted to 0.4 mg/ml and 22.2 nM, respectively, in binding buffer (50 mM Tris-HCl, pH 7.5, 10 mM MgCl2, 1 mM EGTA, 0.1% BSA). Stock solutions (10 mM in 100% DMSO) of test compounds were further diluted in 100% DMSO. Unless otherwise indicated, 10 μl of diluted compound solutions and 90 μL of radioligand (a final concentration of 10 nM in 5% DMSO) were added to each well, and the reaction was started by the addition of 100 μl of membranes (40 μg protein/well).High Throughput Thrombin Receptor Radioligand Binding Assay: Thrombin receptor antagonists were screened using a modification of the thrombin receptor radioligand binding assay of Ahn et al.
