Antiulcer Agents. II. Synthesis and Gastric Acid Antisecretory Activity of N-(3-{3-(Piperidinomethyl)phenoxy}propyl)-4-(1-methyl-1H-tetrazol-5-ylthio)butanamide and Related Compounds.
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.

bulkier aromatic ring systems than the corresponding components of the arylethyl groups of the prototypic methyl ester (carfentanil, 2) and methylene methylether (sufentanil, 3 and alfentanil, 4) 4-propionanilido analgesics. Compound 9A (methyl 1-[2-(1H-pyrazol-1-yl)-ethyl]-4-[(1-oxopropyl)phenylamino]-4- piperidinecarboxylate), which exhibited appreciable mu-opioid receptor affinity, was a more potent
