Abstract:

In this paper, we used polyvinyl alcohol(PVA) aqueous solution as the aqueous phase, poly lactic- co-glycolic acid(PLGA) and curcumin(Cur) dichloromethane solution as the oil phase to prepare curcumin-encapsulated PLGA nanoparticles(PLGA@Cur NPs) by a water-in-oil-in-water double emulsion method. PLGA@Cur improved the dispersion of curcumin and enhanced its antioxidant and anti-inflammatory properties. The results of dynamic light scattering(DLS) and scanning electron microscopy(SEM) showed that PLGA@Cur NPs was homogeneous and spherical with an average size of (340.1±14.9) nm, a polydispersity index(PDI) of (0.22±0.01) and a potential of (-20.20±4.17) mV, and had good stability. The drug loading and encapsulation rate of Cur in PLGA@Cur NPs were determined by high performance liquid chromatography(HPLC), and the encapsulation rate was 15.1% and the drug loading rate was 34.9%. The results at the cellular level showed that PLGA@Cur NPs had good biocompatibility and could scavenge a variety of reactive oxygen species(ROS), and effectively reduced the level of pro-inflammatory cytokines secreted by RAW 264.7 macrophages and alleviate inflammation at the cellular level.
