摘要:

癌症是威胁人类健康的重大疾病之一. 目前, 化疗、放疗和手术治疗是三大常规治疗癌症手段, 虽然这些治疗技术成熟, 但都存在不足, 且治疗成本高昂, 并使得患者在治疗过程中承受痛苦. 因此, 开发活性位点丰富、催化效率高、肿瘤组织识别准确的新型抗肿瘤催化材料, 利用有限的治疗资源, 以最低的毒性取得最佳的治疗效果, 成为癌症治疗的研究新前沿. 随着纳米材料的快速发展, 异核双原子催化剂(HDACs)在保留单原子催化剂的最大原子利用率, 活性位点分布均匀, 孤立单原子的不饱和配位环境和有利于电荷转移的电子结构等优点的基础上, 其两种不同金属原子不仅能提供更丰富的反应活性位点, 两者之间还具有独特的协同作用, 可以有效突破单原子催化剂的线性限制并优化活性中间物种的吸附能垒和构型, 显著提高催化活性和选择性从而获得满意的治疗效果, 在纳米催化肿瘤治疗领域展现出巨大的实际应用潜力.

本文对HDACs的表征手段、制备方法及其近年来在纳米催化肿瘤治疗领域的应用进行了系统的综述. 首先简要介绍了原子水平活性位点的各种表征方法, 特别是原位技术, 讨论了它们应用的侧重点, 并比较了各自的优缺点. 其次, 由于反应原子的高表面自由能、难以调控的动力学行为以及与载体的弱结合使得HDACs在合成过程中极不稳定. 一旦异质活性金属原子之间的距离变近, 就不可避免地发生团聚, 从而形成合金或大尺寸的纳米颗粒. 因此, 实现HDACs的精确和可控合成一直是该领域的研究重点. 本文对HDACs的四大主要制备策略即传统的高温热解法、湿式化学双溶剂法、原子层沉积技术和软模板自组装技术进行了系统总结, 并简要介绍了相关催化剂的应用潜力. 再次, 概括性地阐明了HDACs的抗肿瘤治疗机理, 并依据其发挥疗效的机理, 针对性地将近年来应用于抗癌领域的HDACs划分为芬顿/类芬顿反应或其他机制两大类, 并对这两类HDACs进行了详细的介绍. 最后, 探讨了HDACs在抗肿瘤领域可能面临的问题和挑战并展望了未来研究方向和应用前景, 以期为应用于该领域HDACs的研究提供富有价值的借鉴.

Abstract:

Due to excellent catalytic activity and high atomic utilization rate, single atom catalysts (SACs) have become a rising star in the field of nanocatalytic medicine. Heteronuclear dual-atom catalysts (HDACs) retain the advantages of monoatomic catalysts, have more optionally regulated coordination environment, possess favorable synergistic effects between different active sites, and can break through the restriction of adsorption ratio of SACs, making them the most ideal candidates for catalytic tumor therapy. In this review, we first introduce the advanced characterization methods of HDACs. Then, HDACs in different application fields are classified and elaborated according to various preparation strategies. According to the pharmacodynamic mechanisms, the application of HDACs in the field of nanocatalytic tumor therapy is emphatically introduced. Finally, a concise but focused summary and perspective is provided to outline the current challenges and prospects for future development of HDACs for oncology therapy.
