A drug conjugate is provided herein. The conjugate comprises a protein based recognition-molecule (PBRM) and a polymeric carrier substituted with one or more -L
D
-D, the protein based recognition-molecule being connected to the polymeric carrier by L
P
. Each occurrence of D is independently a therapeutic agent having a molecular weight ≦5 kDa. L
D
and L
P
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.
本文提供一种药物偶联物。该偶联物包括一种基于蛋白质的识别分子(PBRM)和一种聚合物载体,其取代了一个或多个-LD-D,其中,基于蛋白质的识别分子通过LP连接到聚合物载体上。每个D的出现都是独立的,其分子量≦5 kDa,是一种治疗剂。LD和LP是连接治疗剂和PBRM到聚合物载体的连接体。还公开了用于与PBRM偶联形成聚合物-药物-PBRM偶联物的聚合物支架,包括所述偶联物的组合物,其制备方法以及使用偶联物或其组合物治疗各种疾病的方法。
