Nonpeptide glycoprotein IIb/IIIa inhibitors. 8. Antiplatelet activity and oral antithrombotic efficacy of L-734,217.


The antiplatelet activity of L-734,217, a nonpeptide platelet GPIIb/IIIa antagonist, was evaluated in the rat, guinea pig and dog. IC50 for inhibition of in vitro platelet aggregation for these species (agonists: adenosine diphosphate, collagen) were rat, 838,000 and > 1,100,000 nM; guinea pig, 124 and 156 nM; dog, 42 and 50 nM. In an in vivo rat/in vitro… (More)
