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.
本文提供了一种药物结合物。该结合物包括基于蛋白质的识别分子(PBRM)和多聚载体,该多聚载体被取代了一个或多个-LD-D,蛋白质基于识别分子通过LP连接到多聚载体上。D的每个出现都是分子量≦5 kDa的治疗剂。LD和LP是连接治疗剂和PBRM到多聚载体的连接剂。还披露了用于与PBRM结合形成聚合物-药物-PBRM结合物的聚合物支架,包括结合物的组合物,其制备方法以及使用结合物或其组合物治疗各种疾病的方法。
