A drug conjugate is provided herein. The conjugate comprises a protein based recognition-molecule (PBRM) and a polymeric carrier substituted with one or more -LD-D, the protein based recognition-molecule being connected to the polymeric carrier by LP. Each occurrence of D is independently a therapeutic agent having a molecular weight≤5 kDa. LD and LP are linkers connecting the therapeutic agent and PBRM to the polymeric carrier respectively. Also disclosed are polymeric scaffolds useful for conjugating with a PBRM to form a polymer-drug-PBRM conjugate described herein, compositions comprising the conjugates, methods of their preparation, and methods of treating various disorders with the conjugates or their compositions.
本文提供了一种药物共轭物。该共轭物包括一个基于蛋白质的识别分子(PBRM)和一个或多个-LD-D 取代的聚合物载体,基于蛋白质的识别分子通过 LP 与聚合物载体连接。每一个 D 都是分子量小于 5 kDa 的治疗剂。LD 和 LP 分别是连接治疗剂和 PBRM 与聚合物载体的连接体。还公开了用于与 PBRM 共轭以形成本文所述聚合物-药物-PBRM 共轭物的聚合物支架、包含共轭物的组合物、其制备方法以及用共轭物或其组合物治疗各种疾病的方法。
