Substituted 2-sulfinylimidazoles were synthesized and investigated as potential inhibitors of gastric H+/K(+)-ATPase. The 4,5-unsubstituted imidazole series 6-11 and the 1,4,5,6-tetrahydrocyclopent[d]imidazole series 12 were found to be potent inhibitors of the acid secretory enzyme H+/K(+)-ATPase. Structure-activity relationships indicate that the substitution of 2-pyridyl groups at the 1-position
合成了2-亚磺酰咪唑类化合物,并研究了其作为胃H + / K(+)-ATPase的潜在抑制剂。发现4,5-未取代的咪唑系列6-11和1,4,5,6-四氢环戊[d]咪唑系列12是酸分泌酶H + / K(+)-ATPase的有效抑制剂。结构-活性关系表明,在咪唑部分的1位上取代了2-吡啶基,并在2位上结合了(2-氨基苄基)-亚磺酰基,导致了具有良好化学稳定性的高活性化合物。咪唑部分中的其他取代方式导致生物活性降低。选择了2-[(2-氨基苄基)亚磺酰基] -1- [2-(3-甲基吡啶基)]-1,4,5,6-四氢环戊++ ++ ++ [d]-咪唑(12h,T-776)作为潜在的临床候选者进行进一步开发。
