Preparation of DOX-TPP/HA-ss-OA Nanoparticles, Investigation of Drug Release Behavior In Vitro, and Evaluation of Anti-proliferative Activity In Vitro

This study aimed to develop and characterize DOX-TPP/HA-ss-OA nanoparticles, utilizing the mitochondria-targeting prodrug doxorubicin-triphenylphosphine (DOXTPP) and a reduction-sensitive amphiphilic polymer, hyaluronic acid-disulfide-oleic acid (HAss- OA). The research focused on evaluating the drug release behavior of these nanoparticles under varying glutathione (GSH) concentrations and their anti-tumor activity in vitro.
