    摘要： A substituted pyridine derivative represented by the general formula ##STR1## wherein R.sup.1 represents a phenyl or naphthyl group which may optionally be substituted by a substituent selected from the class consisting of a hydroxyl group, lower alkyl groups, lower alkoxy groups, cycloalkyl groups, lower alkoxycarbonyl groups, a phenyl group and halogen atoms; X represents an oxygen atom, a sulfur atom, a carbonyl group, or a group of the formula --CH(OH)-- or --N(R.sup.a)-- in which R.sup.a is a hydrogen atom or a lower alkyl group; Y represents a linear or branched lower alkylene group or a vinylene group which may optionally be substituted by a lower alkyl group, with the proviso that when X is an oxygen or sulfur atom, Y represents the lower alkylene group; R.sup.2 and R.sup.3 are identical or different and each represents a hydrogen atom or a lower alkyl group; R.sup.4 represents a hydrogen atom, a lower alkoxy group, a cycloalkyloxy group, a lower alkylthio group, a cycloalkylthio group, an aryloxy group, an aralkyloxy groups or a group of the formula ##STR2## in which R.sup.b and R.sup.c are identical or different and each represents a hydrogen atom or a lower alkyl group. or R.sup.b and R.sup.c, taken together, may form together with the adjacent nitrogen atom a 5- to 7-membered saturated heterocyclic ring which may optionally contain at least one additional hetero atom selected from the group consisting of oxygen, sulfur and nitrogen atoms and may optionally be substituted by a lower alkyl group; m and n are each 0 or 1, with the proviso that m and n are not 0 at the same time, or an acid addition salt thereof. This compound is useful as an antiulcer agent.
