This invention relates to a compound represented by the formula ##STR1## wherein the ring A stands for a 5-10 membered aromatic heterocyclic group optionally having, besides R.sup.1 and R.sup.2, further substituents; R.sup.1 stands for an optionally substituted hydrocarbon residue which is optionally bonded through a hetero-atom; R.sup.2 stands for a group capable of liberating proton in a living body or a group convertible thereinto; R.sup.3 stands for an 5-7 membered optionally substituted heterocyclic residue having, as a group capable of constituting the ring, carbonyl group, thiocarbonyl group, an optionally oxidized sulfur atom or a group convertible into them; X shows that the ring Y and the ring W are bonded to each other directly or through a spacer having an atomic length of two or less; the ring W and the ring Y are each an optionally substituted aromatic hydrocarbon or aromatic heterocyclic residue; and n denotes an integer of 1 to 3, or a salt thereof and to an angiotensin II antagonistic agent containing the compound (I) or a salt thereof.
该发明涉及一种由下式表示的化合物:其中环A代表一个5-10元芳香杂环基团,除了R.sup.1和R.sup.2外,可能还有进一步的取代基;R.sup.1代表一个可选择取代的碳氢基团,可选择通过一个杂原子键合;R.sup.2代表在活体中能够释放质子的基团或可转化为该基团的基团;R.sup.3代表一个5-7元可选择取代的杂环基团,作为构成环的基团,包括羰基、硫代羰基、一个可选择氧化的硫原子或可转化为它们的基团;X表示环Y和环W直接相互键合或通过一个原子长度为二或更少的间隔键合;环W和环Y分别是可选择取代的芳香碳氢基团或芳香杂环基团;n表示1到3的整数,或其盐,以及含有该化合物(I)或其盐的抗肾素II拮抗剂。
