Tumor retarding (1-benzyl-ethylenediamine)-platin (ii)-complexes

Abstract

There are described (1-benzylethylenediamine)-platin(II)-complexes of the general formula: ##STR1## wherein the radicals R.sub.1, R.sub.2, R.sub.3, and R.sub.4 are the same or different and are hydrogen, a C.sub.1 -C.sub.6 -alkyl group, a benzyl group, or a phenylethyl group, and B is a thienyl radical, an indolyl radical, an imidazolyl radical, or a phenyl radical substituted by the radicals R.sub.5, R.sub.6, an R.sub.7 which are the same or different and are hydrogen, halogen, trihalomethyl, C.sub.1 -C.sub.6 -alkyl, hydroxy, C.sub.1 -C.sub.6 -alkoxy, phenoxy, benzyloxy, C.sub.1 -C.sub.6 -alkanoyloxy, benzoyloxy, C.sub.1 -C.sub.6 -alkanesulfonyloxy, carboxy, C.sub.1 -C.sub.6 -carbalkoxy, cyano, aminocarboxyl, aminocarbonyl, which contains one or two C.sub.1 -C.sub.6 -alkyl radicals, C.sub.1 -C.sub.6 -alkylcarbonyl, nitro, amino, C.sub.1 -C.sub.6 -alkylamino, di-C.sub.1 -C.sub.6 -alkylamino, (C.sub.1 -C.sub.6 -alkyl).sub.3 N.sup.+, C.sub.1 -C.sub.6 -alkanoylamino, C.sub.1 -C.sub.6 -alkyl-C.sub.1 -C.sub.6 -alkanoylamino, C.sub.1 -C.sub.6 -alkanesulfonylamino, C.sub.1 -C.sub.6 -alkyl-C.sub.1 -C.sub.6 -alkanesulfonylamino, aminosulfonyl, aminosulfonyl which contains one or two C.sub.1 -C.sub.6 -alkyl radicals, C.sub.1 -C.sub.6 -alkoxysulfonyl (--SO.sub.2 --O--C.sub.1 --C.sub.6 -alkyl), sulfo (--SO.sub.3 H) or C.sub.1 -C.sub.6 -alkanesulfonyl and two of these groups can be the methylenedioxy group and X is the equivalent of a physiologically compatible anion, as well as optionally their salts with physiologically compatible cations and anions and process of their production.
