Synthesis of a new reactivator of tabun-inhibited acetylcholinesterase

Synthesis of a new asymmetric bisquaternary reactivator of tabun-inhibited acetylcholinesterase-1-(4-hydroxyiminomethylpyridinium)-4-(4-carbamoylpyridinium) butane dibromide is described. Reactivation potency of this oxime is compared to the currently used reactivators—pralidoxime, obidoxime and H-oxime HI-6.
