The invention concerns an isochromane derivative having the general formula I ##STR1## in which R.sub.1 is one to four substituents independently selected from hydrogen, hydroxy, alkyl (1-4 C), alkoxy (1-4 C), halogen, or CF.sub.3, or as two adjacent substituents together a methylenedioxy group; R.sub.2 is one to four substituents independently selected from hydrogen, hydroxy, alkyl (1-4 C), alkoxy (1-4 C), halogen, or CF.sub.3, or as two adjacent substituents together a methylenedioxy group; R.sub.3 is one to four substituents independently selected from hydrogen, hydroxy, alkyl (1-4 C), alkoxy (1-4 C), halogen, or CF.sub.3, or as two adjacent substituents together a methylenedioxy group; R.sub.4 is selected from hydrogen or alkyl (1-4 C); A is a bond or an alkylene or alkylidene group with 1-6 carbon atoms; B is an alkylene or alkylidene group with 1-6 carbon atoms when Y is a bond, or B is an alkylene group with 2-6 carbon atoms when Y is a group selected from O, S, or NR.sub.5 ; X is CH or N; and R.sub.5 is selected from hydrogen or alkyl (1-4 C); or a pharmaceutically acceptable salt thereof. The compounds can be used in the treatment of angina pectoris, cardiac dysrhytmias, cardiomyopathies, stroke, and myocardial infarction.
该发明涉及一种异色满烷衍生物,其具有一般式I ##STR1## 其中R.sub.1是独立选自氢、羟基、烷基(1-4 C)、烷氧基(1-4 C)、卤素或CF.sub.3的1-4个取代基,或作为两个相邻取代基一起是一个亚甲二氧基基团;R.sub.2是独立选自氢、羟基、烷基(1-4 C)、烷氧基(1-4 C)、卤素或CF.sub.3的1-4个取代基,或作为两个相邻取代基一起是一个亚甲二氧基基团;R.sub.3是独立选自氢、羟基、烷基(1-4 C)、烷氧基(1-4 C)、卤素或CF.sub.3的1-4个取代基,或作为两个相邻取代基一起是一个亚甲二氧基基团;R.sub.4选自氢或烷基(1-4 C);A是键或具有1-6个碳原子的烷基或烷基亚甲基基团;当Y是键时,B是具有1-6个碳原子的烷基或烷基亚甲基基团,或当Y是从O、S或NR.sub.5中选取的基团时,B是具有2-6个碳原子的烷基基团;X是CH或N;R.sub.5选自氢或烷基(1-4 C);或其药学上可接受的盐。这些化合物可用于治疗心绞痛、心律失常、心肌病、中风和心肌梗塞。
