在此协议中,多索鲁比辛加载 AS1411-g-PEI-g-PEG 改性金纳米粒子通过三步阿米内反应合成。然后,多索鲁比辛被加载并交付给靶向癌细胞进行癌症治疗。

由于耐药性和毒性,阿霉素在临床上的使用受到限制。该方案提供了一种可降解的载体,用于保持这种治疗剂的释放。这种方法的优点是合成的载体可用于将药物直接递送至癌细胞,仅在癌细胞中诱导细胞死亡。

对于 CT-PEG 合成,首先将 1.46 克琥珀酸酐和 209 毫克 4-二甲氨基吡啶加入 100 毫升圆底烧瓶中。接下来,向培养瓶中加入 15 毫升无水四氢呋喃,并在培养瓶中装上玻璃塞,然后在 0 摄氏度下孵育反应 30 分钟。在孵育过程中,将 4.208 克 PEG、1.8 毫升三乙胺和 15 毫升无水四氢呋喃加入新培养瓶中,并用玻璃塞关闭培养瓶。
