合成了一种新型三嵌段聚合物,并与阿霉素自组装形成载阿霉素胶束。合成过程包括开环聚合、羧化和酰胺化反应,并对其结构进行了表征。药物释放实验表明,该胶束具有控制药物释放的能力。细胞摄取结果表明,载药胶束能够很容易地进入肿瘤细胞,细胞毒性和细胞凋亡实验证实载药胶束对肿瘤细胞有较强的杀伤作用,而空白胶束无细胞毒性。因此,新型聚合物胶束是一种很有前途的抗癌药物载体,以加强癌症治疗。合成了一种新型三嵌段聚合物,并与阿霉素自组装形成载阿霉素胶束。
A novel triblock polymer is synthesized and self-assembled with doxorubicin to form DOX-loaded micelles. The synthetic process involves the ring-opening polymerization, carboxylation and amidation reactions, and the structures are characterized. The drug release test indicated that the micelles have the ability to control the release of drugs. The cell uptake results indicated that the DOX-loaded micelles could enter cancer cells easily, and the cytotoxicity and apoptosis test confirmed that DOX-loaded micelles have a strong killing effect on tumor cells, while the blank micelles do not have cytotoxicity. Therefore, the novel polymer micelles are a promising carrier for delivery of anticancer drugs to enhance cancer treatment. A novel triblock polymer is synthesized and self-assembled with doxorubicin to form DOX-loaded micelles.
