Nitrogen-containing heterocyclic compounds of the formula (I): ##STR1## wherein Y is N or CH; R.sup.1, which may be optionally bound through a hetero atom, is a hydrocarbon residue which may be substituted; R.sup.2 and R.sup.3 which may be same or different, are each independently hydrogen, cyano, nitro, optionally substituted lower alkyl, or --COD wherein D is alkoxy, hydroxy, halogen, or optionally substituted amino: or R.sup.2 and R.sup.3 are taken together to form a benzene ring which may be substituted; the dotted line is a chemical bond; Z is bound to a hetero nitrogen atom and is a group having the formula: ##STR2## wherein R.sup.4 is hydrogen, halogen or nitro, and R.sup.5 is a residue capable of forming an anion or a residue convertible into an anion; A is a direct bond or a spacer having atomic length of two or less between the phenylene group and the phenyl group; and n is an integer of 1 or 2; and the pharmaceutically acceptable salts thereof, have potent angiotensin II antagonist activity and antihypertensive activity, thus being useful as therapeutic agents for treating circulatory system diseases such as hypertensive diseases, heart diseases, strokes, etc.
式(I)的含氮杂环化合物:##STR1## 其中Y为N或CH;R.sup.1是一个可以选择通过杂原子连接的碳氢残基,可以被取代;R.sup.2和R.sup.3可以相同也可以不同,分别独立地为氢、氰基、硝基、可选取代的低碳基或--COD,其中D为烷氧基、羟基、卤素或可选取代的氨基;或R.sup.2和R.sup.3共同形成一个苯环,可以被取代;虚线是化学键;Z与一个杂原子氮原子连接,并且是一个具有以下式子的基团:##STR2## 其中R.sup.4为氢、卤素或硝基,R.sup.5为能够形成负离子的残基或可转化为负离子的残基;A是一个直接键或者具有原子长度为2或更少的间隔物,位于苯基团和苯基团之间;n为1或2的整数;以及其药学上可接受的盐,具有强大的血管紧张素II拮抗活性和降压活性,因此可用作治疗循环系统疾病,如高血压病、心脏病、中风等的治疗剂。
