PURPOSE: The objective of this study was to develop long-circulating solid lipid nanoparticles (LSLN) containing a novel curcumin (CU) derivative (CU1), to improve CU1's pharmacokinetic behavior and its anti-cancer effects in MHCC-97H liver cancer cells.
METHODS: LSLN loaded with CU1 (CU1-LSLN) was optimized and characterized. The cell biological properties and the anti-cancer mechanism of CU1-LSLN on MHCC-97H cells were evaluated by MTT, flow cytometry, Transwell, and Western blot. CU1-LSLN was further evaluated for pharmacokinetic behavior, biodistribution, and liver toxicity in SD rats.
RESULTS: The optimized CU1-LSLN formulation showed the ideal particle size (PS), polydispersity index (PDI), zeta potential (ZP), encapsulation efficiency (EE%), and drug loading (DL%) of 122.10 ± 6.63 nm, 0.19 ± 0.02, -36.30 ± 1.25 mV, 94.98 ± 0.90% and 4.53 ± 0.69%, respectively. X-ray powder diffraction (XRD), differential scanning calorimetry (DSC), and Fourier transform infrared spectrometry (FTIR) indicated that CU1 was well encapsulated by LSLN and existed in amorphous form. Storage stability of CU1-LSLN was up to 180 days with a sustained-release of drug over 96 h. The uptake efficiency of CU1-LSLN to MHCC-97H cells was 3.24 and 2.98 times higher than that of CU and CU1 after treatment for 3 h, which helped to enhance the inhibitive effect of CU1-LSLN on the proliferation, migration, and invasion potential of MHCC-97H cells and increased its ability to promote apoptosis. Meanwhile, the expression levels of NF-κB, COX-2, MMP-2, MMP-9, and uPA decreased significantly. In vivo, CU1-LSLN prolonged the retention time of the drug, the area under the curve (AUC) increased significantly (CU: 69.9-fold, CU1: 85.9-fold), and no significant liver toxicity was observed.
CONCLUSION: CU1-LSLN is a novel preparation with great potential for treating liver cancer.
