Indolin-2-one derivatives preparation thereof and intermediates for the

Abstract

The present invention provides indolin-2-one derivatives of the general formula: ##STR1## wherein R.sub.1 is a C.sub.1 -C.sub.6 alkyl radical or a radical of the general formula: ##STR2## in which A is a straight-chained or branched C.sub.2 -C.sub.4 alkylene radical and Z is an oxygen or sulphur atom, R.sub.2 and R.sub.3, which can be the same or different, are hydrogen or halogen atoms, hydroxyl groups, C.sub.2 -C.sub.6 alkanoyl radicals, C.sub.2 -C.sub.4 alkenyl radicals, C.sub.2 -C.sub.4 alkynyl radicals, C.sub.1 -C.sub.6 alkyl radicals, C.sub.1 -C.sub.6 alkoxy radicals, C.sub.2 -C.sub.4 alkenyloxy radicals, C.sub.2 -C.sub.4 alkynyloxy radicals, C.sub.1 -C.sub.6 alkylthio radicals, C.sub.2 -C.sub.6 alkanoylamido radicals or radicals of the general formula: ##STR3## in which R.sub.4 and R.sub.5, which can be the same or different, are hydrogen atoms, C.sub.1 -C.sub.6 alkyl radicals or C.sub.3 -C.sub.10 cycloalkyl radicals or R.sub.4 and R.sub.5 together represent a C.sub.2 -C.sub.8 alkylene radical optionally interrupted by an oxygen or sulphur atom or by an >N-R.sub.6 group, in which R.sub.6 is a hydrogen atom or a C.sub.1 -C.sub.6 alkyl radical, X is a hydrogen atom, Y is a hydrogen atom or a group of the general formula ##STR4## in which Q is a hydrogen atom or, together with X, can also represent a bond and R.sub.7 is a heterocyclic radical which is optionally substituted one or more times by hydroxyl or C.sub.1 -C.sub.6 alkyl or is a phenyl radical which is optionally substituted one or more times by halogen, hydroxyl, mercapto, carboxyl, C.sub.1 -C.sub.6 alkoxycarbonyl, C.sub.1 -C.sub.6 alkyl, C.sub.1 -C.sub.6 alkoxy, C.sub.1 -C.sub.6 alkylthio, C.sub.1 -C.sub.6 alkylsulphinyl, C.sub.1 14 C.sub.6 alkylsulphonyl, C.sub.2 -C.sub.6 alkanoylamido, C.sub.1 -C.sub.6 alkylsulphonylamido, methylenedioxy, nitro, cyano or amino, with the proviso that R.sub.1 cannot be a C.sub.1 -C.sub.6 alkyl radical when X and Y are both hydrogen atoms; as well as the pharmacologically acceptable salts thereof. The present invention also provides intermediates of the general formula: ##STR5## in which R.sub.7 is a heterocyclic radical which is optionally substituted one or more times by hydroxy or C.sub.1 -C.sub.6 alkyl or is a phenyl radical which is optionally substituted one or more times by hydroxyl, halogen, mercapto, carboxyl, C.sub.1 -C.sub.6 alkoxycarbonyl, C.sub.1 -C.sub.6 alkyl, C.sub.1 -C.sub.6 alkoxy, C.sub.1 -C.sub.6 alkylthio, C.sub.1 14 C.sub.6 alkylsulphinyl, cyano C.sub.1 -C.sub.6 alkylsulphonyl, C.sub.2 -C.sub.6 alkanoylamido, C.sub.1 -C.sub.6 alkylsulphonylamido, nitro amino or methylenedioxy. Furthermore, the invention provides processes for the preparation of the above indolin-2-one derivatives and the above intermediates, as well as pharmaceutical compositions containing the above indolin-2-one derivatives.
