Novel AT(1) receptor antagonists bearing substituted 4-phenylquinoline moieties instead of the classical biphenyl fragment were designed and synthesized as the first step of an investigation devoted to the development of new antihypertensive agents and to the understanding of the molecular basis of their pharmacodynamic and pharmacokinetic properties. The newly synthesized compounds were tested for
设计并合成了带有取代的4-苯基喹啉部分而不是经典联苯片段的新型AT(1)受体拮抗剂,该研究是致力于开发新型降压药以及了解其药效学和分子机制的分子生物学研究的第一步。药代动力学特性。测试了新合成的化合物在大鼠肝膜中置换与AT(1)受体特异性结合的[(125)I] Sar(1),Ile(8)-Ang II的潜在能力。这些AT(1)受体结合研究揭示了几种被研究化合物的纳摩尔亲和力。发现最有效的配体4b,t与氯沙坦等效,并分别具有3-四唑基喹啉或2-氨基-3-喹啉羧酸部分。而且,评估了一些选定的化合物对兔主动脉条中Ang II引起的收缩的拮抗作用,而结合试验4b,t中最有效的化合物在抑制Ang II引起的收缩方面比氯沙坦稍强。最后,通过对分离的配体进行的计算研究以及对与理论AT(1)受体模型复合的配体的计算模拟,使最相关的结构亲和关系数据合理化。
