Asoxime (dichloride)

Asoxime dichloride (HI-6) is an orally active thiosemicarbazone-based antidote. Asoxime dichloride is a reversible inhibitor of AChE, and its core mechanism of action is to re-activate AChE inhibited by nerve toxins, thereby restoring the cholinergic nerve function. Asoxime dichloride significantly restores the function of poisoned muscles without reactivating AChE. Asoxime dichloride is an antagonist of acetylcholine receptors (AChRs), including nicotinic receptor and α7 nAChR. Asoxime dichloride can serve as an effective immunomodulator, improving the immune effect of the nervous system^[1][2]. IC50 & Target:IC50: acetylcholine receptors (AChRs)^[1] In Vivo:Asoxime dichloride (intramuscular injection into the rear limb; 2% and 0.2% of median lethal dose 15.6 and 1.56 mg/kg; 21 or 65 days) significantly improved vaccination efficacy as a dose-dependent manner when KLH is 1 mg/kg. A combination of HI-6 and keyhole limpet hemocyanin (KLH) produces a vaccination of almost the same efficacy as that for Freund's complete adjuvant^[1].
