Novel fused imidazole derivatives of the formula (I):
wherein the ring A, which may be optionally substituted, is a six-membered heteroaromatic group having one or two hetero nitrogen atoms; R¹ is hydrogen or an alkyl, aralkyl or aryl group which may be optionally substituted; R² is hydrogen, halogen or nitro; R³ is a residue capable of forming an anion or a residue convertible into an anion; X is a direct bond or a spacer-having atomic length of two or less; and n is an integer of 1 or 2; and the pharmaceutically acceptable salts thereof have potent angiotensin II antagonist activity and hypotensive activity, thus being useful as therapeutic agents for treating circulatory system diseases such as hypertensive diseases, heart diseases, strokes, etc.
Substituted Imidazo-fused 6-membered heterocycles of structural formula: ##STR1## wherein A, B, C, and D are independently carbon atoms or nitrogen atoms are angiotensin II antagonists useful in the treatment of hypertension and congestive heart failure.
