Abstract

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 compositio…
