  • Title: Inhibitory effect of KW-3635, a new thromboxane A2-receptor antagonist, on arterial thrombosis in guinea pigs.
    Author: Higo K, Karasawa A.
    Journal: Jpn J Pharmacol; 1993 Dec; 63(4):521-3. PubMed ID: 8121085.
    Abstract:
    The antithrombotic effects of the thromboxane (TX) A2-receptor antagonist and aspirin were determined using a photochemically-induced arterial thrombosis model in the femoral arteries of guinea pigs. KW-3635 (sodium (E)-11-[2-(5,6-dimethyl-1-benzimidazolyl)ethylidene]-6,11- dihydrodibenz[b,e]-oxepine-2-carboxylate monohydrate) and BM-13505, both of which are TXA2-receptor antagonists, and aspirin inhibited the thrombus formation at the doses that inhibited the ex vivo platelet aggregation induced by sodium arachidonate (100 microM) or collagen (3 micrograms/ml). These results support the notion that TXA2 is an important mediator in the present model of arterial thrombogenesis.
