(±)-Nornicotine has been used as a neat alkaloid standard to demonstrate the mechanistic role that oxides of nitrogen have in tobacco-specific nitrosamines formation.
Biochem/physiol Actions
Nornicotine, an active metabolite of nicotine, is a nicotinic acetylcholine receptor agonist. Nornicotine is a minor alkaloid of tobacco leaves that serves as a precursor of a carcinogen, N-nitrosonornicotine. N-Demethylation of nicotine gives nornicotine, which occurs especially during tobacco leaf senescence and curing.

Previous results from our laboratory demonstrated that S(-)nornicotine, a major tobacco alkaloid and an active nicotine metabolite present in the CNS, increases dopamine release from rat striatal slices in a concentration-dependent and calcium-dependent manner. The present study determined if S(-)nornicotine-evoked
Nicotine is a tobacco alkaloid known to be important in the acquisition and maintenance of tobacco smoking. However, other constituents in tobacco may contribute to the dependence liability. The present report sought to determine whether nornicotine, a tobacco alkaloid and

We describe a method for the quantitative analysis of nicotine, cotinine, trans-3'-hydroxy cotinine, nornicotine, and anabasine in urine, serum, and plasma using liquid chromatography-tandem mass spectrometry. A mix of deuterium-labeled internal standards (IS) is added to a specimen aliquot. The

The aim of this exploratory study was to develop and validate a liquid chromatography-tandem mass spectrometry (LC-MS-MS) method for the quantification of nicotine, eight nicotine metabolites, and two minor tobacco alkaloids in fortified analyte-free hair and subsequently apply this method
Nornicotine is formed from nicotine by nicotine N-demethylase, a CYP82E family monooxygenase, and accumulates to high levels in some tobacco (Nicotiana tabacum) cultivars and many wild Nicotiana species. Nicotiana langsdorffii does not form nornicotine, whereas the closely related species N.
