Effects in vitro of benthiocarb on rat brain Mg2+-ATPase were studied to elucidate the interaction of benthiocarb with Mg2+-ATPase. Based on IC50 values, it was evident that Mg2+-ATPase was sensitive to benthiocarb. Non-competitive inhibition with respect to activation by ATP

Methoxime (MMB-4) is a leading candidate oxime acetylcholinesterase (AChE) reactivator to replace pralidoxime (2-PAM) for therapeutic treatment of nerve agent intoxication. 4-Pyridine aldoxime (4-PA) is a synthetic starting material, a breakdown product, and a probable metabolite of MMB-4. There is

1,1'-Methylenebis{4-[(hydroxyimino)methyl]pyridinium) dichloride (MMB-4), a promising antidote for organophosphate poisoning, has been shown by chromatography and NMR to be a mixture of geometric isomers, predominantly the E/E form. The chromatographically separated isomers have been isolated, directly characterized by NMR to be

A series of mono pyridinium oximes linked with arenylacetamides as side chains were synthesized and their in vitro reactivation potential was evaluated against human acetylcholinesterase (hAChE) inhibited by organophosphorus inhibitors (OP) such as sarin, VX and tabun. The reactivation data
