Hypotensive activity is exhibited by compounds having the formula ##STR1## and pharmaceutically acceptable salts thereof wherein R.sub.1 is hydrogen or alkyl; R.sub.2 and R.sub.3 are each independently phenyl, substituted phenyl, cycloalkyl, or R.sub.2 is hydrogen and R.sub.3 is heteroaryl; R.sub.4 and R.sub.5 are the same or different and each is hydrogen, hydroxy, alkoxy, alkanoyl or alkyl; R.sub.6 is hydrogen or alkyl; and n is 1, 2, 3 or 4; with the proviso that if R.sub.2 and R.sub.3 are each phenyl, at least one of R.sub.1, R.sub.4, R.sub.5 and R.sub.6 is other than hydrogen.
具有以下结构式的化合物表现出降压活性:##STR1##及其药学上可接受的盐,其中R.sub.1为氢或烷基;R.sub.2和R.sub.3各自独立为苯基、取代苯基、环烷基,或者R.sub.2为氢且R.sub.3为杂环芳基;R.sub.4和R.sub.5相同或不同,各自为氢、羟基、烷氧基、烷酰基或烷基;R.sub.6为氢或烷基;n为1、2、3或4;但如果R.sub.2和R.sub.3各自为苯基,则R.sub.1、R.sub.4、R.sub.5和R.sub.6中至少有一个不是氢。
