ABSTRACT
The prodrug-based nanoassemblies offer an alternative to settle the deficiencies of traditional chemotherapy drugs. In this nanosystem, prodrugs typically comprise drug modules, modification modules, and response modules. The response modules are crucial for facilitating the accurate conversion of prodrugs at specific sites. In this work, we opted for differentiated disulfide bonds as response modules to construct docetaxel (DTX) prodrug nanoassemblies. Interestingly, a subtle change in response modules leads to a "U-shaped" conversion rate of DTX-prodrug nanoassemblies. Prodrug nanoassemblies with the least carbon numbers between the disulfide bond and ester bond (PDONα) offered the fastest conversion rate, resulting in powerful treatment outcomes with some unavoidable toxic effects. PDONß, with more carbon numbers, possessed a slow conversion rate and poor antitumor efficacy but good tolerance. With most carbon numbers in PDONγ, it demonstrated a moderate conversion rate and antitumor effect but induced a risk of lethality. Our study explored the function of response modules and highlighted their importance in prodrug development.
