  [Problem] To provide a novel polymer derivative of a cytidine metabolic antagonist which allows release of a medicament irrespective of enzymes of the living body and is expected to have high therapeutic effects. [Solution] The polymer derivative of a cytidine metabolic antagonist in which a substituent represented by the general formula (I) or the general formula (II) [wherein R 7 and R 8 each independently represent a hydrogen atom or an optionally substituted (C1-C6)alkyl group, R 6 represents a hydrogen atom, an optionally substituted (C1-C40)alkyl group, an optionally substituted (C1-C40)aralkyl group, an optionally substituted aromatic group, an amino acid residue in which the carboxy group is protected, or an optionally substituted sugar residue, CX—CY represents CH—CH or C═C (double bond), and A represents the residue of the cytidine metabolic antagonist except the amino group at the position 4] is bonded to the side-chain carboxy group of a block copolymer of a polyethylene-glycol structural moiety and a polymer having 10 or more carboxy groups.

  [问题] 提供一种新型的胞苷代谢拮抗剂的聚合物衍生物，该衍生物允许药物的释放不受生物体内酶的影响，并有望具有高疗效。 [解决方案] 通过将由一般式（I）或一般式（II）表示的取代基（其中R7和R8各自独立地表示氢原子或可选取代的（C1-C6）烷基，R6表示氢原子，可选取代的（C1-C40）烷基，可选取代的（C1-C40）芳基烷基，可选取代的芳香基，带有保护羧基的氨基酸残基或可选取代的糖残基，CX - CY表示CH-CH或C = C（双键），A表示除位置4的氨基以外的胞苷代谢拮抗剂的残基）连接到具有10个或更多羧基的聚乙二醇结构单元和聚合物的侧链羧基上，得到一种胞苷代谢拮抗剂的聚合物衍生物。
