Ethanone oximes represented by the following general formula:
wherein R¹ represents a cycloalkyl group, aryl group, aralkyl group, aryloxy group, aralkyloxy group, arylthio group or aryl sulfonyl group, those groups being optionally substituted with a substituent selected from an alkyl group having 1 to 3 carbon atoms, an alkoxy group having 1 to 3 carbon atoms and a halogen atom, piperidino group, piperazino group, 4-alkyl substituted piparazino group, imidazolyl group, 4-alkyl substituted imidazolyl group or substituted amino group,
R² represents a hydrogen atom or an alkoxy group having 1 to 3 carbon atoms, and
R³ represents a piperidino group, piperazino group or 4-alkyl substituted piperazino group, or
R¹ and R² together with a phenyl group to which they are attached may form a phenothiazin-2-yl group, N-acetyl-phenothiazin-2-yl group, thianthren-2-yl group, dibenzothiophen-3-yl group, dibenzofuran-3-yl group or a group of the formula:
wherein R⁴ represents a hydrogen atom or an alkyl group having 1 to 3 carbon atoms, or a pharmaceutically acceptable acid addition salts thereof are disclosed. They are a potent antiulcer agent.
