A platinum complex represented by the formula:
wherein R¹ is a (C1 - 18) alkyl group, a (C1 - 18)-alkenyl group or a groupZR⁴ in which Z is -CH=CH- or a (C1 - 5)alkylene group, and R⁴ 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,
R² is hydrogen or a (C1 - 18)alkyl group, R³ is hydrogen or a (C1 - 3) alkyl group, or R² and R³ 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 indicaztes 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.
