PSB-0739 is a high-affinity potent, competitive, nonselective platelet P2Y12 receptor antagonist with a Ki values of 24.9 nM. The P2Y12 receptor plays a crucial role in platelet aggregation. Antithrombotic effect[1].
PSB-0739 is a potent competitive non-nucleotide antagonist at the human P2Y12 receptor with a pA2 value of 9.8[2].
PSB-0739 inhibits ADP-evoked Ca2+ responses with an EC50 of 5.4±1.8 μM and causes a rightward parallel shift in the ADP concentration–response curve in THP-1 cells[3].
PSB-0739 (0.01-0.3 mg/kg, intrathecally) has dose-dependent and significant antihyperalgesic effect in low doses. The minimal effective dose (mED) is 0.1 mg/kg[4].
