有效的癌症治疗方法可以减少和消除全身毒性最小的肿瘤。积极靶向纳米粒子为癌症治疗提供了一种有前景的方法。多糖胎盘硫酸软骨素 A (plCSA) 表达在广泛的癌细胞和胎盘滋养, 和疟疾蛋白 VAR2CSA 可以专门绑定到 plCSA。报告的胎盘硫酸软骨素 a 结合肽 (plCSA BP), 来源于疟疾蛋白 VAR2CSA, 也可以具体绑定到 plCSA 癌症细胞和胎盘滋养。因此, plCSA-BP-共轭纳米颗粒可作为靶向药物向人类癌症和胎盘滋养的工具。在本协议中, 我们描述了一种合成 plCSA-BP-共轭脂质聚合物纳米粒子的方法, 载有阿霉素 (plCSA-DNPs);该方法由单超声波步骤和 bioconjugate 技术组成。此外, 还介绍了几种表征 plCSA DNPs 的方法, 包括测定其理化性质和胎盘绒 (JEG3) 细胞的细胞吸收。
