摘要
Cantharidin (CTD) as a treatment for primary liver cancer are well known, and although structural alteration and nano-delivery are efficient in diminishing toxicity, its urinary and digestive toxicity has hindered its clinical application. Based on the synergistic effect of CTD and baicalin (BA) on proliferation inhibition of liver tumor cells, the highly expressed folic acid (FA) receptor of liver cancer cell membrane and the high negative membrane potential of tumor cell mitochondria, we synthesized CHEMS-FRFK and prepared a dual-ligand modified co-delivery liposomes (FA/FRFK-CTD/BA-Lips). Liposomes were spherical particles with uniform particle size, high encapsulation rate, good stability and no hemolysis. The results confirmed that FA/FRFK-CTD/BA-Lips had good targeting to mitochondria of tumor cells, and its target effect on mitochondria of HepG2 was better than that of Huh-7 cells. Compared with CTD, the cytotoxicity of liposomes on HepG2 is 7.0 times higher, while the cytotoxic effect on normal liver cells Thle-2 is 2.1 times lower. It may be related to increasing clathrin-mediated endocytosis, inhibiting tumor cell migration, arresting cell cycle in G1/G0 phase, and promoting mitochondria-mediated endogenous Bcl-2/Caspase 3 apoptosis pathway. Meanwhile, FA/FRFK-CTD/BA-Lips could alter the pharmacokinetic behavior of CTD and BA by increasing concentrations in vivo, slowing release and excretion, good anti-tumor with no obvious toxicity, and successfully delivered CTD/BA to liver tissue, tumor cells and mitochondria. Therefore, FA/FRFK-CTD/BA-Lips, as a delivery system targeting the mitochondria of liver cancer cells, has promising development potential, and could provide a new strategy for solving the problem of CTD toxicity and the treatment of hepatocellular carcinoma.
