New bis-pyridinium oxime reactivators 6 with CH2O(CH2)2OCH2 and CH2O(CH2)4OCH2 linkers between the two pyridinium rings were designed and synthesized. In the in vitro test of their potency to reactivate AChE inhibited by organophosphorus agents at 5 × 10−3 M concentration, the reactivation ability of 1,2-dimethoxy-ethylene-bis-N,N′-4-pyridiumaldoxime dichloride (6a) was 63% for housefly (HF) AChE inhibited by diisopropyl fluorophosphates (DFP), 51% for bovine red blood cell (RBC) AChE inhibited by DFP, 67% for HF-AChE inhibited by paraoxon, and 81% for RBC-AChE inhibited by paraoxon. Except in the case of DFP-inhibited HF AChE test of 2-PAM, the activities of 6a are much higher than the activities of 2-PAM and HI-6 which are AChE reactivators currently in use.
