[Structure-activity relationship in reactivators of acetylcholinesterase inhibited by phosphoric esters. XII. Hydroxyiminomethylalkylpyridine iodomethylate].

2-Hydroxyiminomethyl-4-alkylpyridine methiodides were prepared and tested for their in vitro reactivating potency on phosphorylated electric eel cholinesterase. They were also tested as in vivo protecting agents: only one of the compounds, 4-methyl-2-hydroxyiminopyridine, offered a greater protection from DFP than 2-PAM, the others had little to no effect.
