ABSTRACT:
Dihydropyridine compounds and salts thereof are provided which exhibit both Ca.sup.2+ -antagonistic and adrenergic beta-receptor blocking activities and therefore are useful for the treatment of ischemic heart diseases and hypertension. The compounds have the formula ##STR1## wherein A represents a straight or branched carbon chain alkylene group having 1 to 10 carbon atoms which may be interrupted by an oxygen atom(s); R.sup.1 and R.sup.4, which may be the same or different, each represents a lower alkyl group; R.sup.2 represents an amino group, ##STR2## R.sup.3 represents a straight or branched carbon chain alkyl group having 1 to 10 carbon atoms which may be interrupted by an oxygen atom(s), or ##STR3## R.sup.5 and R.sup.6, which may be the same or different, each represents a hydrogen atom, a nitro group, a halogen atom, a trifluoromethyl group, a cyano group, a lower alkyl group, a lower alkoxy group or a lower alkenyloxy group; R.sup.7 represents a hydrogen atom, a cyano group, a halogen atom, a lower alkoxy group or a lower alkanoyl group; R.sup.8 and R.sup.9, which may be the same or different, each represents a lower alkyl group or an aralkyl group; and n represents an integer of 1 to 2: these symbols, hereafter, have the same significances.
