摘要:

以聚乙烯醇(PVA)水溶液为水相, 聚乳酸-羟基乙酸共聚物(PLGA)和姜黄素(Cur)的二氯甲烷溶液为油相, 采用水包油包水的双乳液法制备了包载姜黄素的PLGA纳米颗粒(PLGA@Cur NPs), 改善了姜黄素的分散性, 提高了其抗氧化和抗炎性能. 动态光散射粒度仪(DLS)和扫描电子显微镜(SEM)表征结果显示, PLGA@Cur3呈均匀的球形, 平均尺寸为(340±15) nm, 多分散指数(PDI)为(0.22±0.01), 电位为(-20.2±4.2) mV, 具有良好的稳定性. 高效液相色谱(HPLC)分析结果表明, PLGA@Cur3 NPs中Cur的包封率为15.09%, 载药率为34.85%. 细胞水平结果显示, PLGA@Cur NPs具有良好的生物相容性, 能够清除多种活性氧(ROS), 有效降低RAW 264.7巨噬细胞分泌的促炎细胞因子含量, 缓解细胞水平的炎症.

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.
