and the compounds were tested for ability to inhibit platelet aggregation induced by adenosine diphosphate and collagen in rats and guinea pigs ex vivo. Alkyl substituents at the 2-position bearing a basic group were necessary for ex vivo activity. Several of the compounds were potent inhibitors of adenosine diphosphate induced first-phase aggregation, but adverse toxicological findings terminated
合成了一系列取代的1,2-苯并噻唑-3-酮,并测试了这些化合物在离体大鼠和豚鼠中抑制二磷酸腺苷和胶原蛋白诱导的血小板聚集的能力。带有碱性基团的2-位上的烷基取代基对于离体活性是必需的。几种化合物是二磷酸腺苷诱导的第一相聚集的有效抑制剂,但不良的毒理学发现终止了它们的进一步发展。初步研究表明,抑制聚集并不归因于前列腺素合成的抑制或环状3',5'-腺苷单磷酸水平的升高。
