  Reversible inhibitors of the gastric (H+/K+)-ATPase. 3. 3-Substituted-4-(phenylamino)quinolines

  摘要：

  Previously, gastric (H+/K+)-ATPase inhibitors such as 2 have been prepared as analogues of 1a on the presumption that the 3-carbethoxy substituent plays a key role in establishing the orientation of the 4-arylamino group. In this paper we explore further the contribution made to activity by the quinoline 3-substituent. We show th bearing such a substituent, only a particular combination of properties provides high activity, both in as inhibitors of gastric acid secretion in vivo. The ability of the substituent to affect activity by restricting rotation about the C(quin)-N bond through a combination of both a pi-electron withdrawal and hydrogen bonding is supported by the current study. However, high activity is only achieved if the effect of this group on the quinoline pK(a) is kept to a minimum. 3-Acyl substituents provide an optimum combination of electronic properties. From this series, compound 17c (SK&F 96067) was shown to be a potent inhibitor of histamine-stimulated gastric acid secretion oral dosing in the Heidenhain pouch dog and was selected for further development and evaluation in man.

  作为一类新型的胃H + / K + -ATPase抑制剂，合成了4-（苯基氨基）喹啉-3-羧酰胺。

  摘要：

  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。

  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
