ABSTRACT:
Carbostyril compounds or salts thereof of the formula ##STR1## wherein A is a C.sub.1 -C.sub.6 alkylene group; R.sup.1 is a C.sub.3 -C.sub.8 cycloalkyl-C.sub.1 -C.sub.6 alkyl group which may have, as a substituent, a group selected from the group consisting of C.sub.1 -C.sub.6 alkoxycarbonyl groups, a carboxy group, C.sub.2 -C.sub.6 alkanoyloxy-C.sub.1 -C.sub.6 alkyl groups, amino-C.sub.1 -C.sub.6 alkyl groups, C.sub.1 -C.sub.6 alkylamino-C.sub.1 -C.sub.6 alkyl groups and hydroxy-C.sub.1 -C.sub.6 alkyl groups, a C.sub.3 -C.sub.8 cycloalkyl group, a tetrahydropyranyl-C.sub.1 -C.sub.6 alkyl group, a C.sub.1 -C.sub.3 alkylenedioxy group-substituted C.sub.1 -C.sub.6 alkyl group, a phenyl-C.sub.1 -C.sub.6 alkyl group having, as a substituent on the phenyl ring, 1 to 3 groups selected from the group consisting of C.sub.1 -C.sub.6 alkyl groups and a hydroxyl group, or a piperidinyl-C.sub.1 -C.sub.6 alkyl group having a C.sub.1 -C.sub.6 alkyl group as a substituent; R.sup.2 is a 5-membered or 6-membered saturated or unsaturated heterocyclic-C.sub.1 -C.sub.6 alkyl group, said heterocyclic being selected from the group consisting of pyrrolidinyl, morpholino, piperidinyl, thiomorpholino, imidazolyl, 1,2,4-triazolyl, furyl, piperazinyl, pyridyl, tetrahydropyranyl and 1,3-oxathiolranyl groups which may have, as a substituent thereon 1 to 3 groups selected from the group consisting of hydroxy-C.sub. 1 -C.sub.6 alkyl groups, C.sub.2 -C.sub.6 alkanoyloxy-C.sub.1 -C.sub.6 alkyl groups, a hydroxyl group, C.sub.1 -C.sub.6 alkyl groups, amino-C.sub.1 -C.sub.6 alkyl groups, C.sub.1 -C.sub.6 alkylamino-C.sub.1 -C.sub.6 alkyl groups, C.sub.1 -C.sub.6 alkoxy groups, C.sub.1 -C.sub.6 alkoxy-C.sub.1 -C.sub.6 alkoxy groups, C.sub.1 -C.sub.6 alkoxy-C.sub.1 -C.sub.6 alkyl groups, a thio group and C.sub.1 -C.sub.6 alkylamido groups; the carbon-carbon bond between the 3- and 4-positions in the carbostyril skeleton being a single bond or a double bond and pharmaceutical compositions containing the compound as the active ingredient.
