  摘要：

  通过三种合成途径制备了一系列在1位带有一个联苯基甲基的取代的2-丁基苯并咪唑，并评估了其在体外和体内的血管紧张素II（AII）受体拮抗活性。使用牛肾上腺皮质膜测定结合亲和力。相对于未取代化合物（13a）的亲和力，在4-，5-或6-位的取代降低了亲和力。但是，大多数在7位带有取代基的化合物的结合亲和力与DuP 753（氯沙坦）相当。在功能研究中，发现羧基对于对抗AII的拮抗活性非常重要。2-丁基-1-[[[2'-（1H-四唑-5-基）联苯-4-基]甲基] -1H-苯并咪唑-4-，-5-，-6-的比较 AII诱导的兔主动脉环收缩试验中的-7和羧酸（15a-d）清楚地证明了羧基取代位置的重要性。在体内试验中，苯并咪唑-7-羧酸的口服给药对大鼠的AII诱导的升压反应产生了长期抑制作用。发现苯并咪唑环的7位上的最佳取代基是羧基或酯基。代表性化合物2-丁基-1-[[[2'-（1H-四唑-5-基）联苯-4-基]甲基]

  A series of 2-alkylbenzimidazoles bearing a N-phenylpyrrole moiety were synthesized and evaluated as a novel class of AT(1) receptor antagonists. Among them, compounds 10a and 10g inhibited [ I-125] AngII-binding affinity to AT(1) receptor at nanomolar level and potently inhibited the AngII-induced pressor response by oral administration. Moreover, evaluation in spontaneously hypertensive rats showed that 10a is an orally active AT(1) receptor antagonist. (c) 2007 Elsevier Ltd. All rights reserved.
