Asoxime dimesylate  (Synonyms: HI-6 dimesylate)

Asoxime dimesylate (HI-6 dimesylate) is an orally active thiosemicarbazone-based antidote. Asoxime dimesylate 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 dimesylate significantly restores the function of poisoned muscles without reactivating AChE. Asoxime dimesylate is an antagonist of acetylcholine receptors (AChRs), including nicotinic receptor and α7 nAChR. Asoxime dimesylate can serve as an effective immunomodulator, improving the immune effect of the nervous system^[1][2].
