evaluated in vitro for inhibition of platelet aggregation induced by adenosine 5'-diphosphate (ADP), thrombin and collagen. All the tested compounds (except 8 and 9) inhibited platelet aggregation in a dose-dependent manner. The IC50 of the most active substance, compound 2b, was around 60 microM against ADP and collagen as inducers. The inhibition of platelet aggregation caused by test compounds was dependent
已经合成了几种6-芳基-5-加氧的取代的哒嗪酮,并在体外评估了对5'-二磷酸腺苷(ADP),凝血酶和胶原蛋白诱导的血小板聚集的抑制作用。所有测试的化合物(8和9除外)均以剂量依赖的方式抑制血小板凝集。活性最高的物质(化合物2b)对ADP和胶原诱导剂的IC50约为60 microM。受试化合物对血小板聚集的抑制作用取决于功能在5位的氧化程度,IC50值的顺序为R-OH(2a,b,5)
