Pyridinium, imidazolium and quinuclidinium compounds: synthesis, interaction with cholinesterases, and potential antidotes of organophosphorus compounds

2007
Organophosphorus compounds (OP) used as pesticides or warfare nerve agents are strong poisons. They inhibit acetylcholinesterase (AChE) by phosphylating its catalytic site. Substrates and reversible ligands can protect cholinesterases from phosphylation. On the other hand some compounds, due to their structure (mostly oximes) protect the enzyme as well
