Abstract

The purpose of the present invention is to provide a polymeric compound in which a camptothecin compound and an anti-cancer effect enhancer, particularly a PARP inhibitor, are bound to a single molecule, whereby it becomes possible to reduce the toxicity to normal cells and deliver and release the two components to an affected area with high efficiency to thereby improve the pharmacological efficacy of the two components. Provided is a polymeric compound represented by general formula (1).
