Quinolin-2-yl benzoic acid compounds which are useful as intermediates of quinoline compounds having angiotensin II antagonist activity prepared by decarboxylating 2-(carboxyphenyl)-4-quinolinecarboxylic acid compounds in which a carboxyl group bonded to a phenyl group may be esterified, while a carboxyl group bonded to a quinoline ring is not esterified, and both rings may have one or more substituents inert to the decarboxylation reaction.

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.
An isoindazole compound of the formula (1) or a salt thereof; a method for the production thereof; and pharmaceutical use of the compound and a salt thereof, particularly as an angiotensin II antagonist and as an agent for the prophylaxis and treatment of circulatory diseases (particularly hypertension and heart failure); ##STR1## wherein Q is a heterocyclic derivative of the formula (2) or (3) ##STR2## wherein other symbols of the above formulas are as defined in the Specification. The compound and its salt show superior angiotensin II antagonism and are low toxic. Accordingly, they are useful as angiotensin II antagonists for the treatment or prophylaxis of angiotensin II-mediated diseases such as circulatory diseases of hypertension (e.g. essential hypertension, renal hypertension) and heart failure.

A synthesis of all possible N-alkylated 2-n-butyl-imidazo[4,5]pyridine isomers is described as well as their structuralassignment by 1H NMR spectroscopy. One of these derivatives, 2,-n-butyl-3-[2′- (1H-tetrazol-5-yl)-4-biphenylylmethyl]-3H-imidazo[4,5-b]pyridine 9 is a potent angiotensin II receptor antagonist.
描述了所有可能的N-烷基化的2-正丁基-咪唑并[4,5]吡啶异构体的合成及其通过1 H NMR谱的结构分配。这些衍生物中的一种,即2-正丁基-3- [2'-(1H-四唑-5-基)-4-联苯基甲基] -3H-咪唑并[4,5-b]吡啶9是有效的血管紧张素II受体拮抗剂。
