A series of 4-[2-(alicyclic-[1,2,4]oxadiazol-3-yl)phenoxy]-butyric acids were synthesized from N-hydroxy-2-isopropoxy benzamidine in 4 steps with good yields. These [1,2,4]oxadiazoles are novel platelet aggregation inhibitors preventing human platelet aggregation induced by thromboxane derivative U44,619 and adenosine diphosphate. A structure-activity-relationship study revealed that the potency for
以N-羟基-2-异丙氧基苯甲脒为原料,分4步合成了一系列4-[2-(脂环族-[1,2,4]恶二唑-3-基)苯氧基]-丁酸,收率良好。这些 [1,2,4] 恶二唑是新型血小板聚集抑制剂,可防止血栓烷衍生物 U44,619 和二磷酸腺苷诱导的人血小板聚集。一项结构-活性-关系研究表明,这些 5-恶二唑的效力随着脂环的环大小的增加而增加。衍生物 8f 可用作设计更有效的抗血小板药物的模板。
