N-[3-3-(Piperidinomethyl)phenoxy}propyl]butanamides having a 1-methyl-1H-tetrazol-5-ylthio moiety as a pharmacophore and related compounds were prepared and tested for their antisecretory activity against histamine-induced gastric acid secretion in conscious rats with gastric fistulas. Most of the compounds showed antisecretory activity. Among them, N-[3-3-(piperidinomethyl)phenoxy}propyl]-4-(1-methyl-1H-tetrazol-5-ylthio)butanamide (5f) was found to possess the most potent activity, and a possibility of isosteric replacement of the methoxycarbonyl group with 1-methyl-1H-tetrazol-5-yl group was indicated. The structure-activity relationships are also discussed.
本研究制备了以 1-甲基-1H-四唑-5-硫基为药理基础的 N-[3-3-(哌啶甲基)苯氧基}丙基]丁酰胺类化合物及相关化合物,并测试了它们对患有胃瘘的清醒大鼠组胺诱导的胃酸分泌的抗分泌活性。大多数化合物都显示出了抗分泌活性。其中,N-[3-3-(哌啶甲基)苯氧基}丙基]-4-(1-甲基-1H-四唑-5-硫基)丁酰胺(5f)具有最强的活性,并表明了甲氧基羰基被 1-甲基-1H-四唑-5-基团等位取代的可能性。此外,还讨论了结构-活性关系。
