Studies on gastric antiulcer active agents. III. Synthesis of 1-substituted 4-(5-tetrazolyl)thio-1-butanones and related compounds.
Many 1-substituted 4-(5-tetrazolyl)thio-1-butanones were synthesized and tested for antiulcer activity against acetic acid-induced gastric ulcer in rats. These compounds were prepared by the reaction of 5-mercaptotetrazoles and 4-halogeno-1-butanones. Among them, 1-cyclohexyl-4-(1-phenyl-5-tetrazolyl)thio-1-butanone (VIIIp) was found to have the most potent activity. The structure-activity relationships are discussed.
