摘 要 目的 制备并表征姜黄素纳米胶束(简称“Cur/mPEG-PBLA胶束”),并评价其抗酒精性肝病的体外活性。方法 以聚乙二
醇-聚天冬氨酸苄酯嵌段共聚物(mPEG-PBLA)为载体,采用透析法制备Cur/mPEG-PBLA胶束;观察其外观和显微形态,检测其粒
径、多分散性指数、Zeta电位、包封率及载药量,并进行体外释放、pH稳定性、热稳定性、稀释稳定性、储存稳定性、血浆稳定性考察
和溶血实验。以人肝癌细胞、正常肝细胞为对象,以 Cur 对照品溶液为参照,采用无水乙醇干预建立酒精性肝病细胞模型,评价
Cur/mPEG-PBLA胶束对酒精性肝病的体外预防和改善作用。结果 所制Cur/mPEG-PBLA胶束显淡黄色乳光,呈圆球形且分布均
匀,平均粒径约 140 nm,多分散性指数<0.3,Zeta 电位为(-8.15±0.05)mV;包封率及载药量分别为(73.26±3.16)%、(4.87±
0.42)%。Cur对照品在10 h时的累积释放率接近80%;Cur/mPEG-PBLA胶束在8 h时的累积释放率仅为28.94%,在48 h时的累积
释放率才达48.25%。Cur/mPEG-PBLA胶束的pH稳定性、热稳定性均优于Cur对照品溶液,稀释稳定性、储存稳定性、血浆稳定性
均较好,且不会引发溶血现象。Cur对照品溶液和Cur/mPEG-PBLA胶束对2种细胞的酒精性损伤均有不同程度的体外预防和改
善作用;且作用48 h时,Cur/mPEG-PBLA胶束的上述作用均显著优于同质量浓度的Cur对照品溶液(P<0.05)。结论 Cur/mPEG-
PBLA胶束可提高Cur的pH稳定性、热稳定性,延缓其释放速度,同时具有更强的体外抗酒精性肝病活性。

ABSTRACT OBJECTIVE To prepare and characterize curcumin nanomicelles (hereinafter referred to as Cur/mPEG-PBLA
micelles), and to evaluate the in vitro hepatoprotective activity against alcohol liver disease (ALD). METHODS Cur/mPEG-PBLA
micelles were prepared with the dialysis method using methoxy-poly(ethylene glycol)-poly(β-benzyl-L-aspartate) (mPEG-PLGA)
as the carrier. The appearance and microscopic morphology of Cur/mPEG-PBLA micelles were observed, and particle size,
polydispersity index, Zeta potential, encapsulation efficiency and drug loading content were all detected. The in vitro release, pH
stability, thermal stability, dilution stability, storage stability, plasma stability tests, and hemolysis experiments were all
performed. The cell model of ALD was established with anhydrous ethanol intervention using human liver cancer cells and normal
liver cells as objects, Cur reference solution as reference, to evaluate in vitro preventive and ameliorative effects of Cur/mPEG-
PBLA micelles on ALD. RESULTS The prepared Cur/mPEG-PBLA micelles exhibited a pale-yellow milky light, with a spherical
shape and uniform distribution. The average particle size was about 140 nm, and the polydispersity index was less than 0.3. Zeta
potential was (-8.15±0.05) mV; the encapsulation efficiency was (73.26±3.16)%, and the drug loading content was (4.87±
0.42)%. The cumulative release of Cur reference substance was close to 80% at 10 h; the cumulative release of Cur/mPEG-PBLA
micelles at 8 h was 28.94% and only 48.25% at 48 h. pH stability and thermal stability of Cur/mPEG-PBLA micelles were better
than those of Cur reference solution; Cur/mPEG-PBLA
