SCH-79797

Description: SCH-79797 is a novel, potent and selective PAR1 (protease activated receptor 1) antagonist with an IC50 of 70 nM and a Ki of 35 nM. SCH-79797 limits myocardial ischemia/reperfusion injury in rat hearts. SCH79797 dihydrochloride inhibits thrombin-induced platelet aggregation with an IC50 of 3 uM. SCH 79797 protects against ischemia/reperfusion-induced arrhythmias in the rat hearts. SCH 79797 and its N-methyl analogue (SCH 203099) inhibited binding of a high-affinity thrombin receptor-activating peptide ((3)HhaTRAP, Ala-Phe(p-F)-Arg-ChA-HArg-(3)HTyr-NH(2)) to PAR-1 with IC(50) values of 70 and 45 nM, respectively.
