Compounds of formula (I) :
[wherein: A represents a group (IIa), (IIb) or (IIc) :
R¹ is alkyl, alkenyl, cycloalkyl or a group of formula R⁴-Y-R⁵-, where: R⁴ is hydrogen, alkyl, or cycloalkyl, R⁵ is a single bond or alkylene, and Y is oxygen, sulphur or imino group; R² is hydrogen, halogen, Optionally substituted alkyl, optionally substituted alkenyl, optionally substituted cycloalkyl, hydroxy, amino, alkylamino, dialkylamino, formyl, alkylcarbonyl, alkoxy, alkylthio, cyano or nitro; R³ is hydrogen, alkyl, carboxy, protected carboxy, carbamoyl or tetrazol-5-yl; X is of formula -CH=, -N= or -C(COOR⁶)=, where R⁶ is hydrogen or a carboxy-protecting group; Z is a single bond, alkylene or vinylene; and B is carboxy, protected carboxy or tetrazol-5-yl]; and pharmaceutically acceptable salts and esters thereof have the ability to inhibit the action of angiotensin II and thus can be used for the treatment and prophylaxis of hypertension and cardiac iseases.
式(I)化合物:
其中A 代表基团 (IIa)、(IIb) 或 (IIc) :
R¹ 是烷基、烯基、环烷基或式 R⁴-Y-R⁵- 的基团,其中:R⁴ 是氢、烷基或环烷基,R⁵ 是单键或亚烷基,Y 是氧、硫或亚氨基;R² 是氢、卤素、任选取代的烷基、任选取代的烯基、任选取代的环烷基、羟基、氨基、烷基氨基、二烷基氨基、甲酰基、烷基羰基、烷氧基、烷硫基、氰基或硝基;R³ 是氢、烷基、羧基、受保护的羧基、氨基甲酰基或四唑-5-基;X为式-CH=、-N=或-C(COOR⁶)=,其中R⁶为氢或羧基保护基团;Z为单键、亚烷基或亚乙烯基;B为羧基、羧基保护基或四唑-5-基];其药学上可接受的盐类和酯类具有抑制血管紧张素 II 作用的能力,因此可用于治疗和预防高血压和心脏病。
