- 摘要:
- 本发明公开了一种共聚胶束载药纳米颗粒,其是包括非荷电性亲水性聚合物链嵌段、非荷电性疏水性聚合物链嵌段以及阳离子性聚合物链嵌段的嵌段共聚物,非荷电性亲水性聚合物链嵌段和阳离子性聚合物链嵌段通过化学键非荷电性疏水性聚合物链嵌段两端,阳离子性聚合物链嵌段接枝有脂质配体,作为三嵌段共聚物自组装的胶束系统纳米载药颗粒,可以实现siRNA与化疗药物的共传递;三嵌段共聚物是两亲性的,可以自组装成胶束纳米颗粒,制作成本低并且制备方便,亲水性部分增强循环时间,非荷电性疏水性聚合物链嵌段用于包裹阿霉素形成疏水性内核,阳离子性聚合物链嵌段带正电荷,可以携带负电荷siRNA;把胆固醇连接到阳离子性聚合物链嵌段上,提高细胞内吞的效率。
