series of 2-[(cycloalka[b]pyridinyl)sulfinyl]-1H-benzimidazoles (11) was synthesized and tested for antisecretory activity against pentagastrin-induced gastric acid secretion in rats. A novel benzimidazole derivative containing a cyclohepta[b]pyridine moiety was found to be the most potent among the congeners, which included five- to eight-membered cycloalka[b]pyridine ring systems. Some 2-[(6,7,8,9
合成了一系列的2-[((环烷基[b]吡啶基)亚磺酰基] -1H-苯并咪唑)(11),并测试了其对五肽胃泌素诱导的胃酸分泌的抗分泌活性。发现一种新的含有环庚[b]吡啶部分的苯并咪唑衍生物在同类物中最有效,其包括五至八元环烷基[b]吡啶环系统。某些在芳香环上带有各种取代基的2-[(6,7,8,9-四氢-5H-环庚[b]吡啶-9-基)亚磺酰基] -1H-苯并咪唑类似物(14)比奥美拉唑( 1)在体内进行生物检查。选择非对映异构体TY-11345(28Ba)作为有前途的试剂进行进一步评估。
