β-Aminoalcohols as Potential Reactivators of Aged Sarin-/Soman-Inhibited Acetylcholinesterase

b-Aminoalcohols as Potential Reactivators of Aged Sarin-/Soman-Inhibited Acetylcholinesterase

Organophosphate nerve agents inhibit the enzyme acetylcholinesterase (AChE), which is involved in nerve signal transduction, by forming covalent adducts with its catalytic serine residue. AChE adducts with soman and sarin nerve agents undergo dealkylation, a process known as aging, within a few minutes and a few hours, respectively. This transformation is detrimental because it precludes reacti...

Docking Studies, Synthesis, and In-vitro Evaluation of Novel Oximes Based on Nitrones as Reactivators of Inhibited Acetylcholinesterase

Acetylcholinesterase has important role in synaptic cleft. It breaks down the acetylcholineatcholinergic synapsesand terminates the cholinergic effects. Some chemical agents likeorganophosphorus compounds (OPCs) including nerve agents and pesticides react withacetylcholinesteraseirreversibly. They inhibit normal biological enzyme action and resultin accumulation of acetylcholineand show toxic e...

New Cinchona Oximes Evaluated as Reactivators of Acetylcholinesterase and Butyrylcholinesterase Inhibited by Organophosphorus Compounds.

For the last six decades, researchers have been focused on finding efficient reactivators of organophosphorus compound (OP)-inhibited acetylcholinesterase (AChE) and butyrylcholinesterase (BChE). In this study, we have focused our research on a new oxime scaffold based on the Cinchona structure since it was proven to fit the cholinesterases active site and reversibly inhibit their activity. Thr...
