Metabolite Identification
Common NameCotinine N-oxide
DescriptionCotinine N-oxide is a minor metabolite of nicotine, cotinine formation being the major pathway of nicotine metabolism in smokers. Cotinine N-oxide accounts for less than 5% of the nicotine dose. Cotinine N-oxide can be reduced back to the parent amine in vivo. Nicotine is a naturally occurring alkaloid found in many plants. The principal sources of nicotine exposure are through the use of tobacco, nicotine containing gum and nicotine replacement therapies. Nicotine is an amine composed of pyridine and pyrrolidine rings. It has been shown that nicotine crosses biological membranes and the blood brain barrier easily. The absorbed nicotine is extensively metabolized in the liver to form a wide variety of metabolites including and cotinine N-oxide. Nicotine has been shown to affect a wide variety of biological functions ranging from gene expression, regulation of hormone secretion and enzyme activities. (PMID: 16359169 , 15109883 ).
