A 1,4-dihydropyridine derivative of the formula ##STR1## wherein R.sup.1 and R.sup.2 are identical or different and each represents a hydrogen atom, a halogen atom or a nitro group, provided that R.sup.1 and R.sup.2 are not hydrogen atoms at the same time; R.sup.3 represents an alkyl group; R.sup.4 represents an aralkyl group which may be substituted; R.sup.5 and R.sup.7 are indentical or different and each represents an alkyl group; R.sup.6 represents a hydrogen atom or an alkyl group; R.sup.8 represents an alkyl group; R.sup.9 represents a hydrogen atom or an alkyl group; n and m are identical or different and each represents an integer of 0 to 6; provided that when either one of R.sup.1 and R.sup.2 is a hydrogen atom, R.sup.9 is an alkyl group; or an acid addition salt thereof. The 1,4-dihydropyridine derivative is characterized by a strong antihypertensive activity and the long duration of the activity.
一种1,4-二氢吡啶衍生物,其化学式为##STR1##其中R.sup.1和R.sup.2相同或不同,分别代表氢原子,卤素原子或硝基基团,但要求R.sup.1和R.sup.2同时不为氢原子; R.sup.3代表烷基基团; R.sup.4代表可以被取代的芳基烷基基团; R.sup.5和R.sup.7相同或不同,每个代表烷基基团; R.sup.6代表氢原子或烷基基团; R.sup.8代表烷基基团; R.sup.9代表氢原子或烷基基团; n和m相同或不同,每个代表0到6的整数; 但要求当R.sup.1和R.sup.2中任意一个为氢原子时,R.sup.9为烷基基团; 或其酸加成盐。该1,4-二氢吡啶衍生物具有强烈的降压活性和长效活性的特点。
