摘要:

近年来, 随着纳米技术的不断发展, 多功能纳米复合材料在肿瘤治疗领域得到了广泛应用. 因肿瘤的异质性、 复杂性以及多样性的特征, 使得单一的治疗手段很难达到理想的治疗效果. 因此, 将多种治疗方式相结合实现肿瘤的联合治疗成为了研究的热点. 本文设计了一种新型的纳米治疗平台, 在Pt@介孔Au纳米材料(Pt@Au)的表面包覆聚多巴胺(PDA)壳层, 并在PDA壳层中负载阿霉素(DOX), 在PDA壳层表面修饰葡萄糖氧化酶(GOx)和NH2-PEG5K-cRGD. NH2-PEG5K-cRGD可以与肿瘤细胞中过表达的αvβ3整合素特异性结合, 实现纳米治疗平台在肿瘤区域的富集. DOX可以损伤肿瘤细胞的DNA, 用于化学治疗. 介孔Au和PDA优异的光热性能可以用于光热治疗. GOx可以与肿瘤细胞内的葡萄糖反应生成葡萄糖酸和H2O2, 实现饥饿治疗. Pt作为常见的类过氧化氢酶可以催化肿瘤细胞内H2O2分解生成O2, 缓解肿瘤乏氧微环境, 促进饥饿治疗. 因此, 制备的Pt@Au@PDA-DOX-GOx-cRGD具有化疗-光热治疗-自促进饥饿治疗联合治疗肿瘤的能力.

Abstract:

In recent years, with the continuous development of nanotechnology, multifunctional nanocomposites have been widely applied in the field of tumor therapy. Due to the heterogeneity, complexity, and diversity of tumors, single treatment approaches often fail to achieve ideal therapeutic outcomes. Therefore, combining multiple treatment methods to achieve synergistic tumor therapy has become a research hotspot. This paper designs a novel nanotherapy platform. A polydopamine(PDA) shell was coated on the surface of Pt@mesoporous Au nanomaterials(Pt@Au), and doxorubicin(DOX) was loaded into the PDA shell. The surface of the PDA shell was modified with glucose oxidase(GOx) and NH2-PEG5K-cRGD. NH2-PEG5K-cRGD can specifically bind to the overexpressed αvβ3 integrin in tumor cells, facilitating the accumulation of the nanotherapy platform in the tumor region. DOX can damage the DNA of tumor cells and is used for chemotherapy. The excellent photothermal properties of mesoporous Au and PDA can be used for photothermal therapy. GOx can react with glucose in tumor cells to produce gluconic acid and H2O2, achieving starvation therapy. Pt, as a common peroxidase mimic, can catalyze the decomposition of H2O2 in tumor cells to generate O2, alleviating the hypoxic tumor microenvironment and promoting starvation therapy. Therefore, the Pt@Au@PDA-DOX-GOx-cRGD possesses the ability to perform chemotherapy-photothermal therapy-self-enhanced starvation therapy for combined tumor treatment.
