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 IC50 of 70 nM and a Ki of 35 nM. SCH79797 inhibits thrombin-induced platelet aggregation with an IC50 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.

| Animal A (mg/kg) = Animal B (mg/kg) multiplied by | Animal B Km |
| Animal A Km |
For example, to modify the dose of Compound A used for a mouse (20 mg/kg) to a dose based on the BSA for a rat, multiply 20 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for Compound A of 10 mg/kg.
