Abstract
1,4-Dihydropyridine derivatives of formula: ##STR1## wherein Ar.sup.1 represents an aromatic hydrocarbon group or an aromatic heteromonocyclic or heterobicyclic group containing therein 1 to 3 atoms selected from the group consisting of oxygen, sulfur and nitrogen; R.sup.1 represents a hydrocarbon group which may have one or more substituents; A represents (i) a straight chain or branched chain unsaturated hydrocarbon group, (ii) a cyclic unsaturated hydrocarbon group, or (iii) a group selected from the group consisting of --R--O--N.dbd.CH--, --R--N.dbd.N--, --R--CH.dbd.N-- and --R--N.dbd.CH--, in which R is an alkylene group having 1 to 6 carbon atoms; B represents an alkylene or alkenylene group having 1 to 3 carbon atoms, which may have a substituent; Ar.sup.2 represents an aromatic hydrocarbon group or a heterocyclic group; Ar.sup.3 represents a heterocyclic group which may have one or more substituents; and n is 0 or 1, and the corresponding optical active 1,4-dihydropyridine derivatives, having an optically active cite as indicated by *, have both superior vasodilative and platelet aggregation inhibiting activities.
