摘要:

采用薄膜水化法制备了载多烯紫杉醇Solutol HS15/Pluronic F127混合胶束(SF-DTX)及叶酸接枝的Solutol HS15/Pluronic F127载药混合胶束(FSF-DTX)。体外表征实验表明, 两种载药混合胶束体系均呈球型, 粒径分别为(22.2±0.43) nm, (24.3±0.26) nm; 均具备较高包封率, SF-DTX99.05%, FSF-DTX90.28%, 且均有缓释特性。同时, 细胞摄取及细胞毒性实验结果表明两种混合胶束体系均在一定程度上可以逆转肿瘤多药耐药性(MDR), FSF较之于SF胶束体系能更明显增强耐药人口腔上皮细胞癌细胞(KBv)DTX的摄取, 是一种潜在的肿瘤靶向性载药体系。

Abstract:

In this study, two kinds of docetaxel (DTX)-loaded mixed micelles, composed of Solutol HS15 (HS15)/Pluronic F127 (F127) or folate-conjugated F127, (SF-DTX and FSF-DTX), were prepared by the thin-film hydration method and evaluated in vitro. Both SF-DTX and FSF-DTX were spherical with diameter close to 23 nm. They had high encapsulating efficiency (99.05% and 90.28% for SF-DTX and FSF-DTX, respectively) and sustained-release property. SF and FSF were able to enhance the cellular accumulation of DTX in KBv cells and reduce ATP content in A-549 cells. They also were able to reverse multidrug resistance (MDR). In vitro cytotoxicity and cellular accumulation of DTX suggested an active targeting of FSF-DTX. It could be concluded from the results that the novel F127/HS15 system could serve as a potential nanocarrier with the ability of overcoming MDR, and folate-conjugated F127/HS15 might achieve active targeting at the same time.
