2'-Hydroxynicotine (BioDeep_00000027696)

描述信息

2-Hydroxynicotine is a metabolite produced from the degradation of nicotine, an alkaloid found in the nightshade family of plants (Solanaceae), predominantly in tobacco, and in lower quantities in tomato, potato, eggplant (aubergine), and green pepper. Cytochrome P450 2A6 (EC 1.14.14.1) metabolizes nicotine via 2-hydroxylation into 4-(methylamino)-1-(3-pyridyl)-1-butanone with 2-hydroxynicotine as an intermediate (PMID: 11050152). 2-Hydroxynicotine spontaneously yields nicotine-Δ1′(2′)-iminium ion, which is in equilibrium with 4-(methylamino)-1-(3-pyridyl)-1-butanone (PMID: 15734728). About 10\\% of nicotine and its metabolites are excreted as 4-oxo-4-(3-pyridyl)butanoate (keto acid) and 4-hydroxy-4-(3-pyridyl)butanoate (hydroxy acid) in the urine of smokers (PMID: 10548320).
