POLYMERIC MICELLE CONTAINING CISPLATIN ENCLOSED THEREIN AND USE THEREOF

摘要

A complex comprising cisplatin and a poly(ethylene glycol)/poly(glutamic acid) block copolymer, wherein the cisplatin is enclosed in the copolymer through ligand displacement in which a carboxyl anion of the copolymer is replaced with a chlorine ion of the cisplatin. This complex can give a medicine reduced in toxicity and usable by a new method of administration.
