Abstract
Prodrugs can be formed by chemical modification of the existing active pharmaceutical ingredients (APIs); however, this often sacrifices their functional efficacy. Self-immolative linkers have recently attracted attention, as they can be designed to release pristine APIs. Herein, we report a strategy to generate a self-immolative prodrug (SIP) that can release pristine doxorubicin (DOX). Compared to conventional linkers, the key SIP DOX (KSIP-DOX) developed here can rapidly and quantitatively release the API due to its strong leaving group after reduction by thiol groups, which are present in tumors. KSIP-DOX has enhanced cellular uptake and improved anticancer efficacy, demonstrating its utility for cancer treatment.

Abstract
Intracellular delivery of therapeutic proteins remains a challenge for the success of protein-mediated disease treatment. We herein develop a robust nanoplatform made with a TME-pH responsive Meo-PEG-b-PPMEMA polymer and a cationic lipid-like compound G0-C14 for in vivo delivery of cytotoxic saporin and breast cancer therapy. This nanoplatform could respond to a TME pH to rapidly release saporin/G0-C14 complexes, which could significantly improve the uptake of cytosolic saporin by tumor cells and subsequent endosomal escape, thereby leading to an effective inhibition of tumor growth.
