PSB-0739 

PSB-0739 is a high-affinity potent, competitive, nonselective platelet P2Y₁₂ receptor antagonist with a K_i 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].
