Reactivators of organophosphate (OP)-inhibited cholinesterases (ChEs) are believed to give rise to phosphorylated oximes (POX) that reinhibit the enzyme. Diethylphosphoryl oximes (DEP-OX) that were generated in situ were demonstrated in the past to be unstable, yet were more potent inhibitors of acetylcholinesterase (AChE) than the parent OPs. In view of the inconsistencies among reported results,...
A series of carbamate and phenylurea pesticides was studied by ion-trap MS/MS collision-induced dissociation (CID) in the resonant excitation mode. CID mass spectra contained highly abundant daughter ions formed by simple cleavage as well as by rearrangement processes. The formation of rearrangement daughter ions vs. cleavage daughter ions was found to be dependent on the CID voltage and CID time...
