: Liver cancer, especially hepatocellular carcinoma, a prevalent malignant tumor of the digestive system, poses significant therapeutic challenges. While traditional chemotherapy can inhibit tumor progression, its clinical application is limited by insufficient efficacy. Hydrophobic therapeutic agents further encounter challenges including low tumor specificity, poor bioavailability, and severe systemic toxicity. This study aimed to develop a liver-targeted, glutathione (GSH)-responsive micellar system to synergistically enhance drug delivery and antitumor efficacy. : A GSH-responsive disulfide bond was chemically synthesized to conjugate glycyrrhetinic acid (GA) with curcumin (Cur) at a molar ratio of 1:1, forming a prodrug Cur-GA (CGA). This prodrug was co-assembled with glycyrrhizic acid (GL) at a 300% / loading ratio into micelles. The system was characterized for physicochemical properties, in vitro drug release in PBS (7.4) without GSH and in PBS (5.0) with 0, 5, or 10 mM GSH, cellular uptake in HepG2 cells, and in vivo efficacy in H22 hepatoma-bearing BALB/c mice. : The optimized micelles exhibited a hydrodynamic diameter of 157.67 ± 2.14 nm (PDI: 0.20 ± 0.02) and spherical morphology under TEM. The concentration of CUR in micelles can reach 1.04 mg/mL. In vitro release profiles confirmed GSH-dependent drug release, with 67.5% vs. <40% cumulative Cur release observed at 24 h with/without 10 mM GSH. Flow cytometry and high-content imaging revealed 1.8-fold higher cellular uptake of CGA-GL micelles compared to free drug ( < 0.001). In vivo, CGA-GL micelles achieving 3.6-fold higher tumor accumulation than non-targeted controls ( < 0.001), leading to 58.7% tumor volume reduction ( < 0.001). : The GA/GL-based micellar system synergistically enhanced efficacy through active targeting and stimuli-responsive release, providing a promising approach to overcome current limitations in hydrophobic drug delivery for hepatocellular carcinoma therapy.
