SCH79797 dihydrochloride 是一种高效的选择性非肽蛋白酶激活受体 1 (PAR1) 拮抗剂。SCH79797 dihydrochloride 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，Ki 为 35 nM。SCH79797 dihydrochloride 以 IC50 为 3 μM 抑制凝血酶诱导的血小板凝集。SCH79797 dihydrochloride 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 dihydrochloride 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 dihydrochloride is a highly potent, selective nonpeptide protease activated receptor 1 (PAR1) antagonist. SCH79797 dihydrochloride inhibits binding of a high-affinity thrombin receptor-activating peptide to PAR1 with an IC50 of 70 nM and a Ki of 35 nM. SCH79797 dihydrochloride inhibits thrombin-induced platelet aggregation with an IC50 of 3 μM. SCH79797 dihydrochloride has antiproliferative and pro-apoptotic effects, and limits myocardial ischemia/reperfusion injury in rat hearts. SCH79797 dihydrochloride also potently prevents PAR1 activation in vascular smooth muscle cells, endothelial cells, and astrocytes.
