摘要
以叶酸-聚乙二醇-二硬脂酰磷脂酰乙醇胺(FA-PEG 3350-DSPE)和甲氧基聚乙二醇-二硬脂酰磷脂酰乙醇胺(mPEG 2000-DSPE)(摩尔比1∶100)作为混合载体材料,采用固体分散-水化法,制备包载紫杉醇(1)的聚合物胶束,以星点设计-效应面法进行处方优化,并考察了聚合物胶束的理化性质、体外抑制肿瘤细胞生长效果及对巨噬细胞摄取的影响。结果表明,优化所得胶束的包封率为81%、载药量为2.7%、平均粒径为12~16 nm,可持续释放24 h;制品可有效提高1体外抑制肿瘤细胞生长的效果,加入1%的FA-PEG 3350-DSPE可略减弱mPEG 2000-DSPE规避巨噬细胞吞噬的效果。
