Fused heterocyclic compounds of the formula (I): ##STR1## wherein R.sup.1 is an optionally substituted hydrocarbon residue which may be attached through a hetero atom; R.sup.2 is a group capable of forming an anion or a group convertible thereinto; R.sup.3 is an optionally substituted aromatic hydrocarbon or heterocyclic residue which contains at least one hetero atom; X is a direct bond or a spacer having an atomic length of two or less between the R.sup.3 group and the ring W group; W is an optionally substituted aromatic hydrocarbon or heterocyclic residue which contains at least one hereto atom; a,c and d are independently selected from the group consisting of one or two optionally substituted carbon atoms and one or two optionally substituted hetero atoms; b and e are independently selected from the group consisting of one optionally substituted carbon atom and one optionally substituted nitrogen atom wherein one of b or e must be nitrogen; the dotted line is a bond to form one double bond; n is an integer of 1 or 2 and when a, which is an optionally substituted carbon atom, is taken together with R.sup.1, the following group: ##STR2## may form a ring group; provided that when ##STR3## is a benzimidazole, thieno[3,4-d]imidazole, or thieno[2,3-d]imidazole ring, at least one of the group: ##STR4## and R.sup.3 is an optionally substituted heterocyclic residue; and the pharmaceutically acceptable salts thereof, have potent angiotensin II antagonistic activity and antihypertensive activity, thus being useful as therapeutic agents for treating circulatory system diseases such as hypertensive diseases, heart diseases (e.g. hypercardia, heart failure, cardiac infarction, etc.), strokes, cerebral apoplexy, nephritis, etc.
公式(I)的融合杂环化合物:##STR1## 其中R.sup.1是一个可选地取代的烃基团,可以通过一个杂原子连接;R.sup.2是一个能够形成阴离子或可转换成阴离子的团;R.sup.3是一个包含至少一个杂原子的可选地取代的芳香烃或杂环基团;X是R.sup.3基团和环W基团之间的直接键或原子长度为两个或更少的间隔物;W是一个包含至少一个杂原子的可选地取代的芳香烃或杂环基团;a、c和d独立地选自一个或两个可选地取代的碳原子和一个或两个可选地取代的杂原子的组;b和e独立地选自一个可选地取代的碳原子和一个可选地取代的氮原子的组,其中b或e之一必须是氮;虚线是一个形成一双键的键;n是一个1或2的整数,并且当a,即一个可选地取代的碳原子,与R.sup.1一起时,以下组:##STR2## 可以形成一个环状结构;当##STR3## 是一个苯并咪唑、噻吩[3,4-d]咪唑或噻吩[2,3-d]咪唑环时,至少一个是##STR4## 和R.sup.3的可选地取代的杂环基团;以及它们的药用可接受盐,具有强大的血管紧张素II拮抗活性和抗高血压活性,因此作为治疗循环系统疾病如高血压病、心脏病(例如心肌炎、心力衰竭、心肌梗死等)、中风、脑梗塞、肾炎等的治疗剂是有用的。
