title: A new platelet aggregation inhibitor which possesses hypolipemic and uricosuric properties, 2-[3-(2-thiazolylthio)phenyl]propionic acid (TPA).
abstract: In vitro, 2-[3-(2-thiazolylthio)phenyl]propionic acid (TPA) at plasma concentrations ranging from 0.02 to 1.0 microgram/ml prevents aggregation of human platelets induced by various aggregating agents. Oral administration of TPA to guinea pigs inhibits platelet aggregation; the estimated dose to reduce aggregation by 50% is 0.3 mg/kg. TPA protects rabbits against arachidonate-induced thromboembolic death (50% protection at 0.79 mg/kg i.p.). TPA is a potent hypotriglyceridemic agent in rats when present in the diet in concentrations as low as 0.003%. In chimpanzees, TPA is uricosuric at oral doses of 0.625 and 2.5 mg/kg. This rare combination of pharmacological properties suggests that TPA is a potentially useful antithrombotic agent.
