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的化学式为##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R.sup.1和R.sup.2不能同时为氢原子;R.sup.3代表烷基基团;R.sup.4代表可能被取代的芳基烷基基团;R.sup.5和R.sup.7相同或不同,分别代表烷基基团;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,分别代表0至6的整数;但当R.sup.1和R.sup.2中的任何一个是氢原子时,R.sup.9为烷基基团;或其酸盐。这种1,4-二氢吡啶衍生物具有强烈的降压活性和持续时间长的特点。
