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.
新型咪唑衍生物的公式(I)如下:##STR1##,其中R.sup.1是一个可选地取代的烷基团,R.sup.2和R.sup.3独立地是能够形成阴离子或可以转变为阴离子的基团,环A是一个苯环,除了R.sup.2所示的基团外,还可以有其他取代基,而X表示苯基团和苯基团直接连接或通过一个原子长度不超过2的间隔物连接,以及它们的盐,对血管紧张素II显示出拮抗作用,因此作为治疗心血管疾病的药物是有用的。
