摘要:

合成了一种具有声敏活性的红色荧光碳点(CDs), 将乏氧激活化疗药物AQ4N与CDs通过静电相互作用、 氢键和π-π相互作用组装, 制备了CDs@AQ4N纳米组装体. CDs@AQ4N在超声辐照下可有效产生单线态氧(1O2)用于声动力治疗(SDT). SDT过程消耗肿瘤内氧气进一步加剧了肿瘤乏氧, 从而激活AQ4N, 将其转化为具有细胞毒性的AQ4, 在小鼠肿瘤模型下实现了荧光成像指导下的SDT联合化疗. 小鼠主要器官切片、 血常规和血液生化分析结果均证实CDs@AQ4N具有优异的生物安全性.

Abstract:

A red fluorescent carbon dots(CDs) with sonodynamic activity were synthesized, and the CDs@AQ4N nano-assemblies were prepared by assembling the hypoxia-activating drug AQ4N, with CDs via electrostatic interaction, hydrogen bonding, and π-π interactions. CDs@AQ4N could effectively generate singlet oxygen(1O2) for sonodynamic therapy(SDT) of cancer cells. Moreover, the depletion of intra-tumor oxygen during SDT further exacerbated the tumor hypoxia, which activated AQ4N and converted it into cytotoxic AQ4, enabling fluorescence-imaging-guided combination of SDT and chemotherapy for the treatment of mice tumors. The excellent biosafety of CDs@AQ4N was confirmed by mouse major organ sections, blood routine and blood biochemical analyses.

Key words: Carbon dots, Hypoxic activation, Sonodynamic therapy, Chemotherapy, Synergistic therapy
