ABSTRACT:
The present invention provides compounds of the general formula: ##STR1## wherein R.sub.1 is a straight-chained or branched C.sub.1 -C.sub.12 -alkyl radical which can be substituted by phenyl, naphthyl or a C.sub.3 -C.sub.7 -cycloalkyl radical; a straight-chained or branched C.sub.2 -C.sub.6 -alkenyl radical which can be substituted by a C.sub.3 -C.sub.7 -cycloalkyl radical or a phenyl or naphthyl radical; a C.sub.3 -C.sub.7 -cycloalkyl radical or a mono- or bicyclic aromatic radical which is unsubstituted or substituted one or more times, the substituents being C.sub.1 -C.sub.4 -alkyl, C.sub.1 -C.sub.4 -alkoxy, carboxyl or carbethoxy, R.sub.2 and R.sub.3, which can be the same or different, are straight-chained or branched, saturated or unsaturated C.sub.1 -C.sub.6 -alkyl radicals which are optionally substituted by hydroxyl, C.sub.1 -C.sub.3 -alkoxy or C.sub.1 -C.sub.3 -alkoxy-C.sub.1 -C.sub.3 -alkoxy or, together with the nitrogen atom to which they are attached, form a saturated or unsaturated ring which can contain further heteroatoms and is optionally substituted by a lower alkyl or lower alkoxy radical or by an oxygen atom, A is a valency bond or a straight-chained or branched alkylene radical containing up to 6 and preferably up to 3 carbon atoms, R.sub.4 is a mono- or bicyclic aromatic or heteroaromatic radical which is unsubstituted or substituted one or more times, whereby the substituents are alkyl, C.sub.2 -C.sub.6 -alkenyl, alkoxy, C.sub.2 -C.sub.6 -alkenyloxy, hydroxyalkyl, C.sub.2 -C.sub.6 -alkylenedioxy, hydroxyalkoxy, alkoxyethoxy, alkylamino, dialkylamino, alkoxycarbonylethyloxy, alkylthio, alkylsulphinyl, alkylsulphonyl, alkylsulphonyloxy, carboxyl, alkoxycarbonyl, aminocarbonyl, mono- or dialkylaminocarbonyl, haloalkyl or cyano, as well as halogen atoms, such as chlorine, bromine or fluorine, X is a valency bond or a straight-chained or branched, saturated or unsaturated hydrocarbon radical containing up to 6 carbon atoms, Y is a valency bond or an oxygen atom and R.sub.5 is a C.sub.3 -C.sub.7 -cycloalkyl radical or a mono- or bicyclic aromatic or heteroaromatic radical which is unsubstituted or substituted one or more times, the substituents being alkyl, alkoxy, C.sub.2 -C.sub.6 -alkenyloxy, aralkoxy, hydroxyl, hydroxyalkoxy, alkoxyalkoxy, alkoxycarbonylalkoxy, C.sub.1 -C.sub.2 -alkenylenedioxy, dialkylamino, alkylthio, alkylsulphinyl, alkyl-sulphonyl, alkylsulphonyloxy, hydroxyalkyl, carboxyl, alkoxycarbonyl, aminocarbonyl, mono- or dialkylaminocarbonyl or cyano, as well as halogen atoms, such as chlorine, bromine or fluorine, with the proviso that Y cannot be an oxygen atom when X is a valency bond and that when R.sub.1 is a saturated hydrocarbon radical, X must be a radical with at least 2 carbon atoms; as well as the pharmacologically acceptable salts thereof and the optical isomers thereof.
The present invention also provides processes for the preparation of these 1,2-diamino compounds and pharmaceutical compositions containing them.
