The rational design of a specific co-drug delivery platform that can address the unavoidable resistance, toxic side effects and low targeting efficiency of traditional cancer treatments is of great ***, Zn-based MOF-zeolitic imidazole framework-90(ZIF-90) was selected as the drug delivery carrier, with the cancer therapeutic drug mercaptopurine(6-MP) and glucose oxidase(GOD) as the drug models, hyaluronic acid(HA) was used for protection and targeted delivery, which designed and fabricated an intelligent drug delivery platform(6-MP@ZIF-90@GOD@HA). This platform aims to reduce the toxic side effects of 6-MP and enhance its efficacy while improving the targeting ability of GOD,thereby further enhancing the treatment outcome. Notably,results from both in vitro and in vivo experiments demonstrate that the targeted synergistic chemo/reactive oxygen species(ROS)-mediated/starvation therapy inhibited the cancer cell growth while reducing the chemotherapy toxicity, which provides new possibilities for the development of more precise and effective treatment strategies.

Application of nanoscale metal–organic frameworks in tumor immunotherapy

Rare Metals 2024年第10期43卷 4867-4883页

作者： Xiao-Xuan Zeng Jing-Sheng Lu Dong-Wei Ma Yu-Ting Huang Ling Chen Gang Wang Qing Chen Ning Lin college of pharmacy Guangxi Scientific Research Center of Traditional Chinese MedicineGuangxi University of Chinese Medicine Guangxi Zhuang Yao Medicine Center of Engineering and Technology

Immunotherapy has attracted wide attention because it can not only kill tumor cells but also effectively prevent tumor recurrence. However, due to the poor efficacy of the monotherapy in tumor immunotherapy, combination therapies are needed to enhance their efficacy,such as chemodynamic therapy/immunotherapy, photodynamic therapy/immunotherapy, sonodynamic therapy/immunotherapy and so on. Nanoscale metal–organic frameworks(nMOFs) are widely used for drug delivery because of their rich and variable composition, high drug loading capacity and good biodegradability. Compared with other conventional drug delivery systems(DDSs),nMOFs play more advantageous role in inducing immune cell death of tumor cells and combination therapies. This article focuses on the application of n MOFs in tumor immunotherapy in terms of their use as gatekeepers, supplementary agents and drug carriers, respectively, with the aim of providing some ideas and references for the design of smart nanoscale DDS for tumor immunotherapy.
