Target: Prothrombin (SINGLE PROTEIN), Homo sapiens
UniProt: P00734
Assay: Platelet Aggregation (PRP) Assay : The ability of the compounds of the current invention to inhibit platelet aggregation induced by gamma-thrombin was tested in a 96-well microplate aggregation assay format. Briefly, PRP or washed platelet suspension (100 μl) was pre-incubated for 5 minutes at room temperature with varying concentrations of compounds. Aggregation was initiated by ¿10-50 nM gamma thrombin (Haematologic Technologies, Essex Junction, Vt.), which was titrated daily to achieve 80% platelet aggregation. Refludan at 1 U/mL (Berlex, Montville, N.J.) was added to the gamma thrombin sample to prevent PAR1 activation induced by residual alpha-thrombin contamination. The plate was then placed into a 37° C. Molecular Devices (Sunnyvale, Calif.) SPECTRAMAX Plus Plate Reader. The plate was mixed for 10 seconds before the first read and 50 seconds between each read for up to 15 minutes at 405 nM. Data was collected with SOFTMAX 4.71 software. The plate also included an untreated control sample which served as ODmax, while buffer containing no platelets was the ODmin. Platelet aggregation was determined by subtracting the ODmax from the ODmin for the 100% aggregation value. In experimental samples, the observed transmission was subtracted from the minimum value and then compared to the 100% aggregation value to determine the percentage aggregation. IC50 values are determined using Excel Fit software. The aggregation assays were also employed to test the selectivity of the compound against other platelet receptors by using SFFLRR for PAR1, collagen (Chrono-Log, Havertown, Pa.) for collagen receptors, ADP for P2Y1 and P2Y12 and U46619 (Cayman Chemical, Ann Arbor, Mich.) for thromboxane receptors.

Assay: FRET Assay: Compound screening was done via the following method. 10 mM stock solution of test compound in DMSO was prepared by dissolving test compound in DMSO at RT for 1 hour, and then sonicating at 100% output for 8 minutes. If compound is not soluble under this condition, it was diluted to 3 mM. Kinase reaction buffer was prepared containing 10 mM MgCl2, 50 mM HEPES, 1 mM EGTA, 0.01% TWEEN-20, 2 mM DTT. Serial dilutions of the test compounds were prepared at 4× final assay concentrations using Freedom EVO200® dispensing system as follows: 12×10−5 M, 4×10−5 M, 1.33×10−5 M, 4.44×10−6 M, 1.48×10−6 M, 4.92×10−7M, 1.65×10−7 M, 5.48×10−7 M, 1.82×10−8 M, 6.09×10−9, 2.03×10−9 M. Test compounds (2.5 μl at 4× the final assay concentration) was added to wells using Freedom EVO200 dispensing system. As a positive control, 2.5 μl of positive compound was added to assay wells, and 2.5 μl of DMSO to assay wells as vehicle control. Kinase solution was prepared in reaction buffer at 2× final assay concentration. Kinase solution (5 μl) was added to each well of the assay plate. The substrate and ATP solution was prepared in kinase reaction buffer at 4× final assay concentration. The kinase reaction was started by adding 2.5 μl of substrate+ATP mix solution to each well of the assay plate. The plate is mixed on a plate shaker; then covered and allowed to react for 2 hours in the dark at 25° C. without shaking. The reaction was stopped by adding 5 μl of stop solution to each test well followed by mixing and incubation at RT for 10 minutes in the dark. 5 μl of detection mix (detection antibody diluted in detection buffer) was added; the contents of the plate were mixed and then incubated in the dark for 1 hour at RT. The signal was recorded at TR-FR ET mode (665 nm/615 nm).

If compound is not soluble under this condition, it was diluted to 3 mM. Kinase reaction buffer was prepared containing 10 mM MgCl2, 50 mM HEPES, 1 mM EGTA, 0.01% TWEEN-20, 2 mM DTT. Serial dilutions of the test compounds were prepared at 4× final assay concentrations using Freedom EVO200® dispensing system as follows: 12×10−5 M, 4×10−5 M, 1.33×10−5 M, 4.44×10−6 M, 1.48×10−6 M, 4.92×10−7M, 1.65×10−7 M, 5.48×10−7 M, 1.82×10−8 M, 6.09×10−9, 2.03×10−9 M. Test compounds (2.5 μl at 4× the final assay concentration) was added to wells using Freedom EVO200 dispensing system. As a positive control, 2.5 μl of positive compound was added to assay wells, and 2.5 μl of DMSO to assay wells as vehicle control. Kinase solution was prepared in reaction buffer at 2× final assay concentration. Kinase solution (5 μl) was added to each well of the assay plate. The substrate and ATP solution was prepared in kinase reaction buffer at 4× final assay concentration. The kinase reaction was started by adding 2.5 μl of substrate+ATP mix solution to each well of the assay plate. The plate is mixed on a plate shaker; then covered and allowed to react for 2 hours in the dark at 25° C. without shaking. The reaction was stopped by adding 5 μl of stop solution to each test well followed by mixing and incubation at RT for 10 minutes in the dark. 5 μl of detection mix (detection antibody diluted in detection buffer) was added; the contents of the plate were mixed and then incubated in the dark for 1 hour at RT. The signal was recorded at TR-FR ET mode (665 nm/615 nm).
