SCH79797 是一种高效的选择性非肽蛋白酶激活受体 1 (PAR1) 拮抗剂。SCH79797 抑制高亲和力的凝血酶受体激活肽与 PAR1 的结合，IC₅₀ 值为 70 nM，K_i 为 35 nM。SCH79797 以 IC₅₀ 为 3 μM 抑制凝血酶诱导的血小板凝集。SCH79797 具有抗增殖和促凋亡作用，并限制了大鼠心脏的心肌缺血/再灌注损伤。SCH79797 还可以有效地阻止血管平滑肌细胞，内皮细胞和星形胶质细胞中的 PAR1 活化。

SCH79797 is a highly potent, selective nonpeptide protease activated receptor 1 (PAR1) antagonist. SCH79797 inhibits binding of a high-affinity thrombin receptor-activating peptide to PAR1 with an IC 50 of 70 nM and a K i of 35 nM. SCH79797 inhibits thrombin-induced platelet aggregation with an IC 50 of 3 μM. SCH79797 has antiproliferative and pro-apoptotic effects, and limits myocardial ischemia/reperfusion injury in rat hearts. SCH79797 also potently prevents PAR1 activation in vascular smooth muscle cells, endothelial cells, and astrocytes.

SCH79797 inhibits high-affinity thrombin receptor-activating peptide ([H]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 Ca concentration ([Ca]i) in hCASMC. SCH79797 effectively inhibits this increase in [Ca]i. SCH79797 completely inhibits Thrombin- and TK-stimulated [H]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 inhibit

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. has not independently confirmed the accuracy of these methods. They are for reference only.
