A targeting conjugate is provided comprising an active agent, one or more residues of a cyclodextrin (CD)-containing polymer and a biorecognition molecule. The polymer is preferably a peptide or a polypeptide comprising at least one amino acid residue containing a functional side group to which at least one of the CD residues is linked covalently; the biorecognition molecule is covalently bonded directly or via a spacer to the polymer backbone of the CD-containing polymer; and the active agent is noncovalently encapsulated within the cavity of the cyclodextrin residues and/or entrapped within the polymer matrix of the CD-containing polymer.
提供了一种靶向共轭物,包括活性剂、一个或多个含有
环糊精(CD)的聚合物残基和
生物识别分子。该聚合物最好是肽或
多肽,包括至少一个
氨基酸残基,其含有一个功能性侧基,至少一个CD残基与之共价连接;
生物识别分子通过空间连接或直接与CD含聚合物的聚合物骨架共价键合;活性剂非共价地包装在
环糊精残基的空腔内和/或被CD含聚合物的聚合物基质所包裹。
