Popis: | Targeted drug delivery system for tumor cells is an appealing platform on enhancing the therapeutic effects and reducing the side effects of the drug. In this study, we developed folate-modified curcumin (Cur) loaded micelles (Cur-FPPs) for cancer chemotherapy. The targeting material, Folate-PEG3000-PLA2000, was synthesized by the amide bond formation reaction. And the Cur loaded micelles were prepared by thin-film hydration method with mPEG2000-PLA2000 (Cur-PPs) or mPEG2000-PLA2000 and Folate-PEG3000-PLA2000 (Cur-FPPs) as carrier. A central composite design (CCD) was used to optimize the formulation, and the optimized Cur-FPPs was prepared with the weight ratio of Folate-PEG3000-PLA2000 and mPEG2000-PLA2000 at 1:9. The average size of the mixed micelles was 70nm, the encapsulating efficiency and drug-loading were 80.73±0.16% and 4.84±0.01%, respectively. Compared with the Cur propylene glycol solution, the in vitro release of Cur from Cur-FPPs showed a sustained manner. Furthermore, the in vitro cytotoxicity and cellular uptake of Cur-FPPs were significantly enhanced towards MCF-7 and HepG2 cells. The pharmacokinetic studies in rats indicated that a 3-fold increase in the half-life was achieved for Cur loaded micelle formulations relative to solubilized Cur. All the results demonstrated that folate-modified Cur micelles could serve as a potential nanocarrier to improve the solubility and anti-cancer activity of Cur. |
