This invention relates to a compound represented by the formula
wherein the ring A stands for a 5-10 membered aromatic heterocyclic group optionally having, besides R1 and R2, further substituents; R1 stands for an optionally substituted hydrocarbon residue which is optionally bonded through a hetero-atom; R2 stands for a group capable of liberating proton in a living body or a group convertible thereinto; R3 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.
本发明涉及一种由式表示的化合物
其中,环 A 代表 5-10 位芳香杂环基团,除 R1 和 R2 外,还可选择具有其他取代基;R1 代表可选择取代的烃残基,该烃残基可选择通过杂原子键合;R2 代表可在活体内释放质子的基团或可与之转化的基团;R3 代表 5-7 位可选择取代的杂环残基,该杂环残基具有可构成环的基团、羰基、硫代羰基、可选择氧化的硫原子或可与之转化的基团;X表示环Y和环W直接或通过原子长度为2或更小的间隔物相互键合;环W和环Y各自为任选取代的芳香烃或芳香杂环残基;n表示1至3的整数,或其盐,以及表示含有化合物(I)或其盐的血管紧张素II拮抗剂。
