(57) [Problem] To provide a heterocyclic compound having a strong AII antagonistic activity and useful as a therapeutic agent for diseases such as hypertension. SOLUTION: embedded image [R 1 is a hydrocarbon residue which may be bonded through a hetero atom and may be substituted; R 2 is a group capable of forming an anion or a group capable of forming an anion; R 3 is an aromatic hydrocarbon which may be substituted A residue or a heterocyclic residue which may be substituted and contains a hetero atom; X indicates that R 3 and W are bonded directly or via a spacer having 2 or less atom chains; W is an aromatic group which may be substituted Group a hydrocarbon residue or a heterocyclic residue which may be substituted and contains a hetero atom; a, c and d each represent 1 to 2 C or hetero atoms which may be substituted; b and e each may be substituted C; a dashed line indicates that one double bond is present; n is 1 to 2; when C is a group in which a may be substituted, R 1 and a are bonded to each other; May represent a ring]. |
