共载水飞蓟素和多柔比星的二硫化钼纳米片用于肺癌的协同化疗和光热治疗的联合治疗

Co-load of silybin and doxorubicin by MoS2 nanosheets for synergetic chemotherapy and photothermal therapy of lung cancer

  • 摘要: 中药活性成分水飞蓟宾(silybin, SBN) 具有抑制癌症细胞增殖且协同增强化疗药物多柔比星(doxorubicin, DOX) 的抗癌作用。但由于SBN和DOX具有无靶向性、半衰期短等自身缺陷及不同的给药途径和药代动力学过程, 导致此组合药物无法按设定的方式作用于肿瘤, 消除了二者间的协同作用, 进而限制了其在体内的抗肿瘤效果。因此, 本研究拟构建一个以二硫化钼(molybdenum disulfide, MoS2) 材料为基底, 聚乙二醇(polyethylene glycol, PEG) 和唾液酸(sialic acid, SA) 进行修饰、共载SBN和DOX的纳米输送系统。该系统在pH和近红外光的双重刺激下, 诱导组合药物的释放, 提高胞内药物的游离浓度, 进而增强二者间的协同作用。动物福利和实验过程均获得福建中医药大学单位动物伦理委员会的审核并批准。MoS2-PEG-SA-SBN/DOX在动物体内循环, 经高渗透长滞留效应(EPR) 和SA介导的主动靶向有效地在肿瘤部位进行蓄积, 并在近红外光照射下, 实现了对肿瘤的协同化疗和光热治疗的联合治疗, 取得了优异的抑瘤效果。本研究可为临床上肺癌的治疗提供一种新思路和策略。

     

    Abstract: The active ingredient of traditional Chinese medicine, silybin (SBN), can inhibit the proliferation of cancer cells and enhance the anticancer effect of doxorubicin (DOX). However, due to non-targeting and short half-life of SBN and DOX, as well as different administration routes and pharmacokinetic processes, this combination drug cannot act on the tumor in the set order, seriously eliminating the synergistic effect between them and limiting the effect in vivo. Therefore, we intended to construct a nano-delivery system based on molybdenum disulfide (MoS2), modified by polyethylene glycol (PEG) and sialic acid (SA), and co-loaded with SBN and DOX. The system induced the release of combined drugs under the dual-stimulation of pH and near infra-red (NIR), increased the free concentration of intracellular drugs, so as to achieve the synergistic effect between them. The animal welfare and experimental procedures were in accordance with the regulations of the Animal Ethics Committee of Fujian University of Traditional Chinese Medicine. MoS2-PEG-SA-SBN/DOX circulated in vivo, and effectively accumulated at tumor sites through enhanced permeability and retention effect (EPR) and SA-mediated active targeting. Under near infrared light irradiation, MoS2-PEG-SA-SBN/DOX realized the combination of synergistic chemotherapy and photothermal therapy for tumor, thus achieving excellent anti-tumor effect in vivo. This study can provide a new idea and strategy for the clinical treatment of lung cancer. Taken together, MoS2-PEG-SA-SBN/DOX can offer a new idea and strategy for the clinical treatment of lung cancer.
