reactivators of OP-inhibited AChE are no longer effective. Realkylation of aged AChE may provide a route to reversing aging. We designed and synthesized a library of quinonemethideprecursors (QMPs) as proposed realkylators of aged AChE. Our lead compound (C8) from an in vitro screen successfully resurrected 32.7 and 20.4% of the activity of methylphosphonate-aged and isopropyl phosphate-aged electric-eel AChE

Disclosed herein are compounds, compositions, and methods for reactivating or realkylating aged acetylcholinesterase inhibited by or conjugated to the organophosphorus compound. The organophosphorus compound can be a nerve agent. The acetylcholinesterase can be in the central nerve system (CNS) and/or the peripheral nervous system (PNS) of a subject. Accordingly, methods for ameliorating, diminishing, reversing, treating or preventing the toxic effects of an organophosphorus compound in a subject are provided herein. Methods for prophylactic or therapeutic treatment of exposure to an organophosphorus nerve agent are also provided.
