A drug conjugate is provided herein. The conjugate comprises a protein based recognition-molecule (PBRM) and a polymeric scaffold having one or more -L
D
-D, the PBRM being connected to the polymeric scaffold by L
p
, wherein the polymeric scaffold comprises a linear, branched or cyclic polymer having four or more —OH groups. 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 scaffold 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。该结合物包括一种基于蛋白质的识别分子(PBRM)和一个具有一个或多个-LD-D的聚合物支架,其中PBRM通过Lp连接到聚合物支架上,聚合物支架包括具有四个或更多—OH基团的线性、分支或环状聚合物。每个D的出现都是独立的,具有分子量<5 kDa的治疗剂。LD和Lp是连接治疗剂和PBRM到聚合物支架的连接剂。还公开了用于与PBRM结合形成聚合物-药物-PBRM结合物的聚合物支架,包括结合物的组成,其制备方法以及使用结合物或其组成物治疗各种疾病的方法。
