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.
本发明提供了二氢吡啶化合物及其盐,其具有钙离子拮抗和肾上腺素β受体阻滞活性,因此可用于治疗缺血性心脏病和高血压。该化合物的化学式为##STR1##其中A代表直链或支链碳链亚烷基,其具有1-10个碳原子,可以被一个或多个氧原子所中断;R1和R4,可以相同也可以不同,每个代表低碳基;R2代表氨基,##STR2##R3代表直链或支链碳链烷基,其具有1-10个碳原子,可以被一个或多个氧原子所中断,或者##STR3##R5和R6,可以相同也可以不同,每个代表氢原子、硝基、卤素原子、三氟甲基基团、氰基、低碳基、低碳氧基或低碳烯氧基;R7代表氢原子、氰基、卤素原子、低碳氧基或低碳酰基;R8和R9,可以相同也可以不同,每个代表低碳基或芳基烷基;n代表1-2的整数:这些符号在此以后具有相同的意义。
