The higher toxicity of neonicotinoid insecticides such as N-(6-chloropyridin-3-ylmethyl)-2- nitroiminoimidazolidine (imidacloprid) to insects than mammals is due in large part to target site specificity at the corresponding nicotinic acetylcholine receptors (nAChRs). We propose that neonicotinoids with a protonated N-unsubstituted imine or equivalent substituent recognize the anionic subsite of the mammalian α4β2 nAChR whereas the negatively ...
