摘要:通过改进固相合成法制备了硼碳氮纳米管(BCNNTs),并利用 XRD、FTIR 和 SEM 对其进行了表征。然
后,采用叶酸(FA)对 BCNNTs 进行功能化修饰,用于负载阿霉素(DOX),构建了 FA-BCNNTs-DOX 靶向给
药系统,并评价了该载药系统的抗肿瘤效果。结果表明,DOX 有效负载到 BCNNTs 和 FA-BCNNTs 上,其负载
量分别为 67.33 和 87.11 mg/g。与 DOX 和 BCNNTs-DOX 相比,FA-BCNNTs-DOX 能引起更多的人乳腺癌
MDA-MB-231 细胞死亡,这归因于在叶酸受体介导的内吞作用下,MDA-MB-231 细胞对 FA-BCNNTs-DOX 的
摄取能力得到明显提高。在肿瘤细胞酸性条件下,FA-BCNNTs-DOX 释放 DOX,DOX 在细胞核内逐步积累,
从而产生优异的抗肿瘤效果。

Abstract: Boron carbonitride nanotubes (BCNNTs) were prepared via an improved solid-state synthesis
method and characterized by XRD, FTIR and SEM. Then the targeted drug delivery system of
FA-BCNNTs-DOX was constructed by loading doxorubicin (DOX) into folate (FA) functionalized
BCNNTs, and analyzed for its anti-tumor performance. The results showed that DOX was successfully
encapsulated into BCNNTs and FA-BCNNTs with a loading capacity of 67.33 and 87.11 mg/g, respectively.
Compared with DOX and BCNNTs-DOX, FA-BCNNTs-DOX led to more significant human breast cancer
MDA-MB-231 cells growth inhibition, which was attributed to the enhanced FA-BCNNTs-DOX uptake
capacity of MDA-MB-231 cells via folate receptor-mediated endocytosis. Under the acidic environment of
tumor cells, DOX was released from FA-BCNNTs-DOX, and gradually accumulated in the nucleus, thus
producing excellent anti-tumor effects.
