The irreversible inhibition of acetylcholinesterase (AChE) by organophosphorous chemical warfare agents necessitates that antidotes be administered for effective treatment. Currently no antidote is known that resurrects the phosphyl-AChE complex once aging has occurred. This report characterizes the affinities of over 30 new AChE inhibitors which could act as resurrecting agents for the aged AChE-OP adduct.
