A series of hydantoin prostaglandin analogues, in which the hexamethylene moiety of the acid side chain was replaced by other spacing groups possessing either ether, sulphide and/or olefin functionality, were prepared and evaluated for platelet aggregation inhibiting activity. The 4‐thia analogue 13 proved to be the most potent inhibitor (ca. 22x PGE1) and the 3‐thia‐ and 3‐oxa‐analogues, 6 and 10 respectively
制备了一系列乙内酰脲前列腺素类似物,其中酸侧链的六亚甲基部分被具有醚、硫化物和/或烯烃官能团的其他间隔基团取代,并评估了血小板聚集抑制活性。4-硫杂类似物 13 被证明是最有效的抑制剂(约 22 倍 PGE1),而 3-硫杂和 3-氧杂-类似物,分别为 6 和 10,与 BW245C(约 14 倍 PGE1)大致相当。Z-烯烃类似物(例如11)通常比它们的E-异构体(例如12)更有效。详细讨论了结构-活性关系。
