A novel material with dual activity toward organophosphate (OP) poisoning, based on Zr-MOF-808 and neutral oxime RS69N, has been prepared. The hybrid material has a significant drug payload (5.2 ± 0.9 oxime to MOF-808 molar ratio) and shows a sustained oxime release in simulated physiological media, leading to the successful reactivation of OP-inhibited acetylcholinesterase. At the same time, the hybrid system presents an efficient and moderately fast removal rate of a toxic organophosphorus model compound (diisopropylfluorophosphate) from simulated physiological media ( = 183 min; 95% removal rate after 24 h).

一种基于 Zr-MOF-808 和中性肟 RS69N 的新型双重活性有机磷（OP）中毒治疗材料已经被制备出来。该复合材料具有较高的药物负载量（MOF-808 与肟的摩尔比为 5.2 ± 0.9），并在模拟生理介质中表现出持续的肟释放，从而成功地使被 OP 抑制的乙酰胆碱酯酶重新活化。同时，该混合体系对模拟生理介质中的有毒有机磷模型化合物（二异丙基氟膦酸酯）具有高效且适中的快速去除率（ = 183 min；24 h 后去除率达到 95%）。
