Catalog Number: 1592
Chemical Name: N3-Cyclopropyl-7-[[4-(1-methylethyl)phenyl]methyl]-7H-pyrrolo[3,2-f]quinazoline-1,3-diamine dihydrochloride
Biological Activity
Potent, selective non-peptide PAR1 receptor antagonist (IC50 = 70 nM). Inhibits haTRAP-induced- but not γ-thrombin-, ADP- or collagen-induced human platelet aggregation. Also selectively blocks PAR1 agonist- or thrombin-induced increases in cytosolic Ca2+ in vascular smooth muscle cells.
