Research use only, not for human use.

SCH79797 dihydrochloride is an effective and selective antagonist of protease activated receptor 1 (PAR1) with an IC50 of 70 nM and a Ki of 35 nM.

SCH79797 dihydrochloride is an effective and selective antagonist of protease activated receptor 1 (PAR1) with an IC50 of 70 nM and a Ki of 35 nM. SCH79797 dihydrochloride has antiproliferative and pro-apoptotic effects.(In Vitro):SCH79797 dihydrochloride inhibits thrombin-induced platelet aggregation with an IC50 of 3 μM. In NIH 3T3 cells, SCH79797 dihydrochloride inhibits serum-stimulated activation of p44/p42 mitogen-activated protein kinases (MAPK) at low concentrations and induces apoptosis at higher concentrations. SCH79797 dihydrochloride inhibits high-affinity thrombin receptor-activating peptide ([3H]haTRAP) binding in a competitive manner. SCH79797 dihydrochloride inhibits α-thrombin- and haTRAP-induced aggregation of human platelets. Thrombin produces transient increases in cytosolic free Ca2+ concentration ([Ca2+]i) in hCASMC. SCH79797 dihydrochloride effectively inhibits this increase in [Ca2+]i. SCH79797 dihydrochloride completely inhibits Thrombin- and TK-stimulated [3H]thymidine incorporation . (In Vivo):In male Sprague Dawley rats, SCH79797 dihydrochloride (2.5 μg/kg, 10 μg/kg, 25 μg/kg, 50 μg/kg, 100 μg/kg, and 250 μg/kg; i.v.) reduces myocardial necrosis following I/R in the intact rat heart in two rat models of myocardial ischemia/reperfusion (I/R) injury immediately before or during ischemia.

SCH79797 inhibits high-affinity thrombin receptor-activating peptide ([3H]haTRAP) binding in a competitive manner. SCH79797 inhibits α-thrombin- and haTRAP-induced aggregation of human platelets, but does not inhibit human platelet aggregation induced by the tethered ligand agonist for protease-activated receptor-4 (PAR-4), γ-thrombin, ADP, or collagen. Thrombin produces transient increases in cytosolic free Ca2+ concentration ([Ca2+]i) in hCASMC. SCH79797 effectively inhibits this increase in [Ca2+]i. SCH79797 completely inhibits Thrombin- and TK-stimulated [3H]thymidine incorporation .SCH79797 is able to interfere with the growth of several human and mouse cell lines, in a concentration-dependent manner. The ED50 for growth inhibition iss 75 nM, 81 nM and 116 nM for NIH 3T3, HEK 293 and A375 cells, respectively. In NIH 3T3 cells, SCH79797 inhibits serum-stimulated activation of p44/p42 mitogen-activated protein kinases (MAPK) at low concentrations and induces apoptosis at higher concentrations.

SCH79797 (2.5-250 μg/kg; intravenous injection; male Sprague Dawley rats) treatment immediately before or during ischemia reduces myocardial necrosis following I/R in the intact rat heart in two rat models of myocardial ischemia/reperfusion (I/R) injury. This response is dose-dependent with the optimal dose being 25 μg/kg. Animal Model:Male Sprague Dawley rats (8 weeks of age) with myocardial I/R injury Dosage:2.5 μg/kg, 10 μg/kg, 25 μg/kg, 50 μg/kg, 100 μg/kg, and 250 μg/kg Administration:Intravenous injection Result:Immediately before or during ischemia reduced myocardial necrosis following I/R in the intact rat heart.
