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.

solubility, which renders it unsuitable for rapid administration. Previous prodrugs of 2 aimed at improving solubility by incorporating enzymatically labile amino acid and phosphate ester promoieties. These approaches were effective but led to limitations with in vivo administration. Herein, we disclose a pH-responsive water-solubleprodrug strategy to improve exposure to 2 through enzyme-independent activation
