In search for inhibitors of gastric H+/K+-ATPase, 4-(phenylamino)quinoline-3-carboxamides were synthesized and evaluated for antisecretory activity against histamine-induced gastric acid secretion in rats. These compounds were synthesized by condensation of aniline derivatives with N-substituted 4-chloroquinoline-3-carboxamides, which were obtained from treatment of 4(1H)-quinolinone-3-carboxylic acid
为了寻找胃H + / K + -ATP酶的抑制剂,合成了4-(苯氨基)喹啉-3-羧酰胺并评估了其对组胺诱导的大鼠胃酸分泌的抗分泌活性。这些化合物是通过将苯胺衍生物与N-取代的4-氯喹啉-3-羧酰胺缩合而合成的,后者是由亚硫酰氯处理4(1H)-喹啉酮-3-羧酸而获得的。大多数化合物抑制大鼠中组胺诱导的胃酸分泌。其中,N-烯丙基-4-(2-乙基苯基氨基)喹啉-3-羧酰胺(4h)是最有效的抑制剂,并且作为候选抗溃疡药的分布最佳。该化合物显示出可逆的K +竞争性胃H + / K + -ATPase抑制活性。
