The objective of the present study was to develop PTF-loaded solid lipid nanoparticles (PTF-SLNs) and investigate their efficacy in treating lung cancer. The PTF-SLNs were prepared by the thin film hydration method and verified by FTIR and TEM. Their physicochemical properties were characterized by particle size, polydispersity index (PDI), zeta potential, entrapment efficiency (EE), drug loading (DL), etc. Then, the pharmacodynamic studies of PTF-SLNs were performed on Lewis lung cancer cells and tumor-bearing mice. Finally, the safety studies were assessed by organ index, serum biochemical indicators, and histopathological changes. The PTF-SLNs were characterized by around 50 nm sphere nanoparticles, sustained ideal stability, and controlled drug release effects. The pharmacodynamic evaluation results showed that PTF-SLNs had stronger anti-tumor efficacy than PTF. An in vitro study revealed a more obvious cytotoxicity and apoptosis effect. The IC 50 values of PTF and PTF-SLNs were 67.43 μg/mL and 20.74 μg/mL, respectively. An in vivo study showed that the tumor inhibition rates of 2 g/kg PTF and 0.4 g/kg PTF-SLNs were 59.97% and 64.55%, respectively. The safety preliminary study indicated that PTF-SLNs improve the damage of PTF to normal organs to a certain extent. This study provides a nanoparticle delivery system with phenolic herbal extract to improve anti-tumor efficacy in lung cancer. |
