denoted as CPOF–DOX, formed robust unimolecular micelles with an average diameter of 18 nm in aqueous media. More importantly, these unimolecular micelles showed higher drug loading capacity and more controllabledrug release characteristics, compared to our previous unimolecular micelles of β-cyclodextrin-poly(lactic acid)-b-poly[(oligo ethyleneglycol) methyl ether methacrylates] that physically encapsulated
多功能稳定且对刺激有反应的药物输送系统对癌症的有效治疗至关重要,原因是它们具有以下优点:提高了癌症靶向效率,改善了药代动力学,减少了药物浸出并减少了不良副作用。在这里,我们报告了基于星形两亲共聚物单分子胶束的强大且对pH值敏感的抗癌药物递送系统。(表示为聚合物CPOFs)通过官能化benzoaldehyde和亲水性聚一步法原子转移自由基聚合[(低聚乙二醇)甲基醚甲基丙烯酸酯]的合成轻便从heptakis核心共聚单体[2,3,6-三Ø-(2-溴-2-甲基丙酰基]-β-环糊精作为引发剂。阿霉素(DOX)作为抗癌药通过pH敏感的席夫碱键与CPOF的苯甲醛基共价连接。表示为CPOF-DOX,形成强大的单分子胶束在含水介质18纳米的平均直径。更重要的是,这些单分子胶束显示出更高的药物装载容量和更可控的药物释放特征,相较于我们的β环糊精以前单分子胶束-聚(乳酸) - b -聚[(低聚乙二醇)甲醚甲基丙
