Novel imidazole derivatives of the formula (I): ##STR1## wherein R.sup.1 is an optionally substituted alkyl group, R.sup.2 and R.sup.3 are independently a group capable of forming an anion or a group which can be changed thereinto, ring A is a benzene ring optionally having, besides the group shown by R.sup.2, further substituents, and X shows linkage of phenylene group and phenyl group directly or through a spacer whose atomic length is not more than 2 and a salt thereof, show antagonistic actions to angiotensin II, thus being useful as therapeutics for cardiovascular diseases.
式(I)中的新型咪唑衍生物:##STR1## 其中,R.sup.1是可选取的取代烷基,R.sup.2和R.sup.3分别是能形成阴离子的基团或可转化为该基团的基团,环A是苯环,可选取除R.sup.2所示基团外的其他取代基,X表示苯基和苯基之间的直接连接或通过原子长度不超过2的间隔基团连接,以及其盐,表现出对肾素-血管紧张素系统的拮抗作用,因此可用作心血管疾病的治疗药物。
