We have in vitro tested the ability of common, commercially available, cholinesterase reactivators (pralidoxime, obidoxime, methoxime, trimedoxime and HI-6) to reactivate human acetylcholinesterase (AChE), inhibited by five structurally different organophosphate pesticides and inhibitors (paraoxon, dichlorvos, DFP, leptophos-oxon and methamidophos). We also tested reactivation of human butyrylc...
Seven new oxime-based acetylcholinesterase reactivators were compared with three currently available ones (obidoxime, trimedoxime, HI-6) for their ability to lessen cholinesterase inhibition in blood and brain of cyclosarin-treated rats. Oximes were given at doses of 5% their LD(50) along with 21 mg/kg atropine five min before the LD(50) of cyclosarin (120 ug/kg) was administered. Blood and bra...
Abstract Background & Objective: oximes as Acetylcholinesterase (AChE) reactivators were developed for the treatment of organophosphate compounds (OPCs) intoxication. Oximes also bind to the active site of AChE, simultaneously acting as reversible inhibitors. Organophosphorus compounds (OPCs) such as soman, sarin, or VX react with acetyl cholinesterase irreversibly. In this research, a group o...
In this article, we have followed up the relationship between the ability to reactivate acetylcholinesterase inhibited by organophosphorus compounds and the length of linking chain between two 4-hydroxyiminomethylpyridinium rings of acetylcholinesterase reactivators. α,ω-bis(4hydroxyiminomethylpyridinium) alkanes have been used as the tested acetylcholinesterase reactivators. These oximes diffe...
