sulfinyl]-N-(4-pyridinyl)-3-pyridinecarboxamides. was synthesized and evaluated for gastric antisecretory activities. Several of the compounds synthesized exhibited potent inhibitory activities against [14C]aminopyrine accumulation stimulated by dibutyryl cyclic AMP in isolated rabbit parietal cells and histamine-induced gastric acid secretion in pylorus-ligated rats by intraduodenal administration. In particular
新系列的2-[((2-氨基苄基,4-氨基苄基和α-甲基苄基)亚磺酰基] -N-(4-吡啶基)-3-吡啶甲酰胺。合成并评估胃的抗分泌活性。合成的几种化合物对二丁酰基环AMP刺激的离体兔壁细胞刺激了对[14C]氨基比林累积的抑制作用,十二指肠内给药对幽门结扎的大鼠组胺诱导的胃酸分泌产生了抑制作用。特别是2-[((4-甲氧基-α-甲基苄基)亚磺酰基] -N-(4-吡啶基)-3-吡啶甲酰胺(13b)的极性更大的非对映异构体在体内的抑制活性与奥美拉唑和是比奥美拉唑更具选择性的(H + / K +)-ATPase抑制剂。
