A series of N-[biphenylyl(tetrazolyl)methyl]-2-butylimidazoles containing variously substituted diazine or pyridine moieties either as their free bases or N-oxide derivatives attached to the 4-position of the imidazole ring was synthesized and tested for interaction with the AT1 receptors of rat adrenal cortex membranes (receptor binding assay). Some compounds were then chosen for further evaluation
合成了一系列N- [联苯基(四唑基甲基)甲基] -2-丁基咪唑,它们含有不同取代的二嗪或吡啶部分作为游离碱或连接到咪唑环4位的N-氧化物衍生物,并测试了与大鼠肾上腺皮质膜的AT1受体(受体结合测定)。然后选择一些化合物以在体内进行进一步评估,以在有意识的血压正常的大鼠中由A II诱导的升压反应。发现在AT1结合测定中最有效的是其中二嗪或吡啶环氮与两个杂芳族环之间的连接点相邻的化合物,例如2-丁基-4-(3,6-二甲基吡嗪-2- yl)-1-[[[2'-(1H-四唑-5-基)-联苯-4-基]甲基] -1H-咪唑(3b)或2-丁基-4- [5-(甲氧羰基)吡啶- 2-基] -1-[[2' -(1H-四唑+++-5-基)联苯-4-基]甲基] -1H-咪唑(6c)。与2-丁基-4-[(3-甲氧基羰基)-6-甲基-N-一样,在吡啶环氮上邻有一个稳定基团的吡啶N-氧化物咪唑的结合亲和力和口服活性得到显着改善。氧吡啶吡啶-2-基]
