Targeted carrier transfer carrier polymer and drug containing polymer

摘要

Formula (a) (d) 20 ~ 500; R is h, alkyl, benzyl; R may be the same or different. A polymer substituted by Hydra Dino Glu (b), sugar modified Glu (formula C) and (2) hydrazino Glu (b), sugar modified Glu (c), and drug binding Glu (d). The polymer of the present invention is a carrier and a drug carrier carrier which indicates the transferability of the target organ (cell), and is useful as medicine.
