The invention relates to isoquinoline carboxylic acid derivatives and related compounds of the formula:
wherein:
R and R4 are hydrogen, loweralkyl, aralkyl;
R1 is alkyl of from 1 to 10 carbon atoms; substituted alkyl of from 1 to six carbon atoms; aralkyl and heteroaralkyl optionally substituted in the aryl and heteroaryl groups;
R2 is hydrogen, alkyl of from 1 to six carbon atoms optionally substituted;
R3 is hydrogen, halo, or alkoxy; and,
the pharmaceutically acceptable salts thereof;
which are useful as angiotensin converting enzyme inhibitors and as antihypertensives; process for preparing and pharmaceutical composition containing the same.
本发明涉及异喹啉羧酸衍生物及相关化合物,其式如下: 其中:R和R4为氢、低级烷基、芳烷基;R1为1至10个碳原子的烷基;1至6个碳原子的取代烷基;芳基和杂芳基中任选取代的芳基和杂芳基;R2为氢、1至6个碳原子任选取代的烷基;R3为氢、卤素或烷氧基;及其药学上可接受的盐;这些化合物可用作血管紧张素转换酶抑制剂和降压药;制备工艺和含有这些化合物的药物组合物。
