POLYMERIC DERIVATIVE OF CYTIDINE METABOLIC ANTAGONIST
摘要
<p>[PROBLEMS] To provide a derivative of a cytidine metabolic antagonist which can exert a high therapeutic effect at a low dose. [MEANS FOR SOLVING PROBLEMS] A polymeric derivative of a cytidine metabolic antagonist which comprises a polymeric compound having a polyethyleneglycol moiety and a polymer moiety having a carboxyl group in a side chain and a cytidine metabolic antagonist, which has such a structure that the carboxyl group in the side chain of the polymeric compound and an amino group in the cytidine metabolic antagonist are bound together to form an amide bond.</p>
