Biological Activity

SCH 79797 dihydrochloride is a potent, selective non-peptide PAR1 receptor antagonist (IC50 = 70 nM). Inhibits haTRAP-induced- but not γ-thrombin-, ADP- or collagen-induced human platelet aggregation. Selectively blocks PAR1 agonist- or thrombin-induced increases in cytosolic Ca2+ in vascular smooth muscle cells. Also broad spectrum antibiotic. Kills bacteria by a dual action of inhibiting dihydrofolate reductase and interfering with bacterial cell membrane integrity.
