Description

PTA2 is a stable analog of TXA2. It is a TP receptor antagonist and an inhibitor of thromboxane synthase.1,2 PTA2 inhibits U-46619-induced cat coronary artery constriction (ID50 = 0.1 µM), U-46619-induced aggregation of human platelets (IC50 = 2 µM), and rabbit platelet thromboxane synthase (ID50 = 50 µM). PTA2 does not affect PGI synthase up to a concentration of 100 µM.1
