The study presents a hierarchical drug delivery system, HA-GDT-Lip, which exhibits high cell uptake efficiency and mitochondrial targeting ability, inducing cell apoptosis and showing excellent antitumor activity and in vivo safety.
Chemotherapy targeting mitochondrial is a faster and more sensitive anti-tumor therapy strategy. In this study, a hierarchical drug delivery system HA-GDT-Lip was constructed by coupling glycyrrhetinic acid (GA), triphe-nylphosphine (TPP), and doxorubicin (DOX), encapsulating them in cationic liposomes (CLs), then coating the surface of CLs with HA. HA-GDT-Lip nanoparticles can be accumulated in tumor tissue through the EPR effect, then achieve tumor cell-specific endocytosis mediated by the CD44 receptor, DOX can be successfully delivered into mitochondria through the combined action of GA and TPP. Physicochemical properties analysis showed that HA-GDT-Lip nanoparticles were uniform in size and spherical in shape. In vitro cell experiments showed that HA-GDT-Lip had high cell uptake efficiency and mitochondrial targeting ability. In addition, HA-GDT-Lip could induce MPTP opening and accelerate cell apoptosis. Meanwhile, HA-GDT-Lip showed excellent antitumor ac-tivity and in vivo safety in tumor-bearing nude mice. In conclusion, HA-GDT-Lip may serve as a promising mitochondrial delivery system to reduce the side effects of anticancer drugs and improve their antitumor efficacy.
