Oxime@Zirconium-Metal-Organic Framework Hybrid Material as a Potential Antidote for Organophosphate Poisoning

Inorg Chem. 2023 Apr 3;62(13):5049-5053. doi: 10.1021/acs.inorgchem.3c00121. Epub 2023 Mar 20.

Abstract

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 (t1/2 = 183 min; 95% removal rate after 24 h).
