Pyridinium-2-carbaldoximes with quinolinium carboxamide moiety are simultaneous reactivators of acetylcholinesterase and butyrylcholinesterase inhibited by nerve agent surrogates

Journal of Enzyme Inhibition and Medicinal Chemistry, 2021
The pyridinium-2-carbaldoximes with quinolinium carboxamide moiety were designed and synthesised as cholinesterase reactivators. The prepared compounds showed intermediate-to-high inhibition of both cholinesterases when compared to standard oximes. Their

PHOSPHORYLPHOSPHATASE AND OXIMES [PDF]

British Journal of Pharmacology and Chemotherapy, 1961
The effects of pralidoxime iodide, 1,1‐trimethylenebis(4‐formylpyridinium bromide) dioxime and diacetyl monoxime on the activity of phosphorylphosphatase prepared from pig kidney in vitro have been studied. It was found that these oximes, even at high concentrations, did not affect the activity of the enzyme.
