PHOSPHINE TRANSITION METAL COMPLEX, METHOD FOR PRODUCING SAME AND ANTITUMOR AGENT CONTAINING SAME

摘要

Disclosed is a novel phosphine transition metal complex exhibiting excellent antitumor activity while having few side effects. Specifically disclosed is a novel phosphine transition metal complex represented by the following general formula (1). (1) (In the formula, A represents an alkylene group, a phenylene group or a cis-vinylene group; M represents a gold, silver, copper or platinum atom; B<SUP>1</SUP> and B<SUP>2</SUP> respectively represent a heterocyclic group which may have a substituent containing a trivalent phosphorus atom which can be covalently bonded to A and coordinately bonded to M; and C represents an anion atom.)
