The present invention provides isoquinolinedione derivatives of the general formula: ##STR1## wherein R.sub.1 is a hydrogen atom or an alkyl, alkenyl or cycloalkyl radical which is optionally interrupted by a heteroatom or by a heteroatom substituted with an alkyl radical, R.sub.2 is a hydrogen atom or an alkyl or alkenyl radical, or together with R.sub.1, represents a cycloalkylene, alkylidene or cycloalkylidene radical which is optionally interrupted by a heteroatom or by a heteroatom substituted by an alkyl radical and R.sub.3 is a radical of the general formula: ##STR2## which can be in the 5- 6-, 7- or 8-position of the isoquinoline-1,3-dione and in which R.sub.4 and R.sub.5, which can be the same or different, are hydrogen atoms or alkyl, trihaloalkyl, cycloalkyl, cycloalkenyl, dealkylaminoalkyl, alkoxycarbonylalkyl, alkylcarbonyl, aryl or heterayl radicals and X is an oxygen or sulphur atom or a radical of the general formula .dbd.N--R.sub.6, in which R.sub.6 is a hydrogen atom, a cyano group of an alkyl radical; and the physiologically acceptable salts thereof. The present invention also provides processes for the preparation of these compounds and pharmaceutical compositions containing them. These new compounds have a blood pressure lowering effect and/or influence thrombocyte aggregation, improve the microcirculation, and exert a positive intropic effect, thus having therapeutic and prophylactic effects.
本发明提供了一般式为:##STR1##的异喹啉二酮衍生物,其中R.sub.1是氢原子或烷基、烯基或环烷基基团,可以由一个杂原子或由一个被烷基基团取代的杂原子中断;R.sub.2是氢原子或烷基或烯基基团,或者与R.sub.1一起代表一个可以由一个杂原子或由一个被烷基基团取代的杂原子中断的环烷烃基、烷基亚甲基或环烷基亚甲基基团;R.sub.3是一般式为:##STR2##的基团,可以在异喹啉-1,3-二酮的5-、6-、7-或8-位上,其中R.sub.4和R.sub.5可以相同也可以不同,是氢原子或烷基、三卤代烷基、环烷基、环烯基、去烷基氨基烷基、烷氧羰基烷基、烷基羰基、芳基或杂芳基基团,X是氧原子或硫原子或一般式.dbd.N--R.sub.6的基团,其中R.sub.6是氢原子、氰基或烷基基团;以及其生理上可接受的盐。本发明还提供了制备这些化合物的方法和含有它们的药物组合物。这些新化合物具有降低血压和/或影响血小板聚集、改善微循环、产生正性肌力作用的效果,因此具有治疗和预防作用。
