title: Design and synthesis of new bis-pyridinium oxime reactivators for acetylcholinesterase inhibited by organophosphorous nerve agents.
abstract: New bis-pyridinium oxime reactivators connected with a CH(2)CH(2)OCH(2)CH(2) linker between two pyridinium rings were designed and synthesized. In the test of their potency to reactivate AChE inhibited by cyclosarin, the bis-pyridinium oxime 6b achieved reactivation potency higher than 10% at the lower concentration 10(-4)M.
