Provided herein are dendrimer-targeting agent conjugates comprising a dendrimer, the dendrimer comprising a core unit and lysine or lysine analogue building units, a HER2 targeting agent which is a peptidic moiety having a molecular weight of up to about 80 kDa and comprising an antigen-binding site, which is covalently linked by a spacer group, and a therapeutic agent which is covalently linked to a surface building unit of the dendrimer. Also provided herein are compositions comprising the conjugates, and therapeutic methods using the conjugates, particularly for treating cancer.
本文提供了树状聚合物靶向剂共轭物,包括一个树状聚合物,该树状聚合物包括一个核心单元和赖氨酸或赖氨酸类似物构建单元,一个HER2靶向剂,该HER2靶向剂是一个分子量高达约80kDa的肽基部分,包括一个抗原结合位点,该位点通过一个间隔基团共价连接,以及一个治疗剂,该治疗剂与树状聚合物的表面构建单元共价连接。本文还提供了包括这些共轭物的组合物,以及使用这些共轭物的治疗方法,特别用于治疗癌症。
