摘要: 青蒿琥酯,是一种青蒿素衍生的倍半萜类抗疟药物,因对疟原虫的特异作用而引起医药科学家的关注。然而,青蒿琥酯提取步骤复杂,需要使用大量有机溶剂且能耗高。本实验利用金属-有机框架材料易修饰和多孔的特性,构筑出一类功能化的UiO-66以应用于青蒿琥酯吸附研究。选用氨基和氟基作为亲疏水基团,研究不同比例对青蒿琥酯的吸附性能,同时考虑到UiO-66孔径尺寸较青蒿琥酯更小,通过添加适量水分子,构筑缺陷的功能化锆基MOF以提高其孔径。实验结果表明,氟基氨基化UiO-66的吸附容量是25 mg/g,比UiO-66单体吸附容量高出10 mg/g;缺陷氟基氨基化UiO-66的吸附容量提升至33.0 mg/g,表现出更优异的吸附性能。本实验通过材料的合理设计和改性,显著提高了吸附容量和选择性,为青蒿琥酯等药物的纯化和生产提供了一种潜在的工业应用方案。

Abstract: Artesunate, a sesquiterpenoid antimalarial drug derived from artemisinin, has attracted attentions of pharmaceutical scientists due to its specific effect on malaria parasites. However, the extraction process of artesunate is complex, requiring a large amount of organic solvents and high energy consumption. The easily modifiable and porous properties of metal-organic framework materials were used to construct a functionalized UiO-66 for the study of artesunate adsorption property. Amino and thiol groups were selected as hydrophilic and hydrophobic groups, and their influences on the adsorption properties for artesunate at different ratios were studied. Considering that the pore size of UiO-66 is smaller than that of artemether, a defect type functionalized zirconium based MOF was constructed by adding an appropriate amount of water molecules to enhance its pore size. The experimental results show that the adsorption capacity of fluorinated aminated UiO-66 is 10 mg/g higher than that of UiO-66 monomer. The defect fluorinated amination UiO-66 has increased adsorption capacity of 33.0 mg/g, demonstrating superior adsorption property. This experiment significantly improved the adsorption capacity and selectivity through the rational design and modification of materials, providing a potential industrial application solution for the purification and production of drugs such as artesunate.
