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。
