(±)-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.
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

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
The assay of biomarkers in biological material is the most popular and reliable method in estimate exposure to tobacco smoke. Nicotine and its metabolites qualify to the most specific biomarkers for tobacco smoke. Currently the most often used are cotinine
Tobacco consumption is a global epidemic responsible for a vast burden of disease. With pharmacological properties sought-after by consumers and responsible for addiction issues, nicotine is the main reason of this phenomenon. Accordingly, smokeless tobacco products are of growing popularity

Neuronal nicotinic acetylcholinic receptors (nAChR) are promising targets for the development of novel analgesics. Nicotine and other nAChR-agonists produce profound analgesia in rodent models of acute and persistent pain. However, significant side-effects are of concern. Nornicotine (N-desmethyl-nicotine) appears to activate
