摘要: 本文设计、合成了一系列咳嗽衍生物(I-II),并检测了它们的血管紧张素受体拮机活性。以ZD-731(pA2 = 84)为先导化合物, 用生物电子等排的N-苯基吡咯羧酸、N-苯基吡咯四氮唑和苯氧基苯乙酸代替ZD-8731的联苯四氮哇获得化合物(I)(II)(III)。结果这些结构变化有损于活性。在离体试验中(兔胸主动脉坏), 所有的化合物均显示了竞争性拮抗活性。这三类化合物的活性最高者分别为(Id)(pA2值为6.8), (IIa)(pA2值为77)(IIIc)(pA2值为77), 活性分别比ZD-873140512倍。本文并对它们的构效关系和构象比较进行了讨论。

Abstract: The design, synthesis and angiotensin II(A II) antagonist activities of a series of quinoline derivatives (I~III) with ZD-8731 as lead compound are described. The biphenyl tetrazole moiety of ZD-8731 was replaced by bioisosteric N-phenylprrole carboxylic acid, N-phenylpyrroletetrazole and phenoxyphenylacetic acid to give compounds (I), (II) and (III), respectively. However,these changes proved to be detrimental to activities. In a test for amagonizing A II in vitro usingisolated rabbit aorta rings, all the compounds exeded competitive antagonism. The most potent active angiotensin II receptor antagoniSts of these series wee (Id) (pA2 = 6.8), (IIa) (pA2 = 7.7) and (IIIc) (pA2 = 7.2), respectively, which had the activity 1/40, 1/5 and 1/12 that of ZD-8731 (pA2 = 8.4), respectively. Their structure-activity relationships and conformational comparis0n are discussed.
