Eight structurally different acetylcholinesterase reactivators derived from currently commercially available oximes were tested for their potency to reactivate acetylcholinesterase inhibited by pesticide paraoxon (P) and DFP (D). Housefly AChE (F) and bovine red blood cell AChE (B) were used as the source of the cholinesterases. Ellman's method was taken to examine cholinesterases activity. The results show that four AChE reactivators are potent AChE reactivators, able to reach reactivation potency of more than 30% in all cases - PF, PB, DF and DB. Their reactivation potency was comparable with that of pralidoxime and even higher compared with that of HI-6, standard AChE reactivators currently available on the market.
