Novel fused thiophene derivatives of the formula (I): ##STR1## wherein W is ##STR2## R.sup.1 and R.sup.2 which may be same or different, are each independently hydrogen, halogen, cyano, nitro, acylamino, or a hydrocarbon residue which may be substituted; R.sup.3 is hydrogen, optionally substituted alkyl or alkenyl, or --COD wherein D is hydrogen, alkoxy, hydroxy, halogen, or optionally substituted amino; R.sup.4 is hydrogen, halogen or nitro; R.sup.5 is a residue capable of forming an anion or a residue convertible into an anion; R.sup.6 is hydrogen or optionally substituted alkyl or alkenyl; 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.
新型融合噻吩衍生物的化学式(I):##STR1## 其中W为##STR2## R.sup.1和R.sup.2可以相同也可以不同,分别独立地为氢、卤素、氰基、硝基、酰胺基或可被取代的碳氢残基;R.sup.3为氢、可选择取代的烷基或烯基,或--COD,其中D为氢、烷氧基、羟基、卤素或可选择取代的氨基;R.sup.4为氢、卤素或硝基;R.sup.5为能形成负离子的残基或可转化为负离子的残基;R.sup.6为氢或可选择取代的烷基或烯基;A为苯基和苯基之间具有两个或更少原子长度的直接键或间隔物;n为1或2的整数;及其药学上可接受的盐具有强效的血管紧张素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疾病、心脏病、中风等的治疗剂。
