Abstract
A platinum complex represented by the formula: ##STR1## where X is ##STR2## wherein R.sup.1 is a (C1-18) alkyl group, a (C1-18)alkenyl group or a group --Z--R.sup.4 in which Z is --CH.dbd.CH-- or a (C1-5)alkylene group, and R.sup.4 is a phenyl group, a hydroxyphenyl group, a (C7-12)alkoxyphenyl group, a halogenophenyl group, a nitrophenyl group, or (C8-13)alkoxycarbonylphenyl group, a cyclohexyl group having a (C1-5)alkyl substituent, ##STR3## R.sup.2 is hydrogen or a (C1-18)alkyl group, R.sup.3 is hydrogen or a (C1-3) alkyl group, R.sup.2 and R.sup.3 are linked together to form a (C2-7)alkylene group; the dotted line indicates that the bond may be either a single bond or a double bond; the chain line indicates a conjugated system; the 1,2-diaminocyclohexane moiety has a cis-, trans-l- or trans-d-configuration; and Y is an anion. This platinum complex is useful in the treatment of tumors.
