RESUMEN
The prodrug strategy serves well in drug formulation and delivery. Two disulfide-based PEGylated prodrugs were developed and the drug reconversion upon different conditions were studied in detail. The reconversion-induced oversaturation phenomenon was firstly reported here. We found the prodrug can co-assemble with parent drug via π-π stacking into well-defined nanoparticles. The PEG layer of the self-assembled nanoparticles improved the stability of the PEGylated prodrug by reducing the contact with biological enzymes. The nanoparticles also show favorable antitumor efficacy, both in vitro and in vivo.
