Cotinine

• Description :

  Cotinine ((-) -Cotinine) is an orally active alkaloid found in tobacco and is the primary metabolite of nicotine. Cotinine is metabolized by CYP2A13 into trans-3'-hydroxycotinine. Cotinine is used as a biomarker to measure exposure to tobacco smoke components. Cotinine has vasodepressor activity. The mixture of cotinine and nicotine (Nicotine) has antiproliferative activity against pterygium. (S) - (-) -Cotinine activates nicotinic acetylcholine receptors (nAChR) in a calcium-dependent manner, leading to the release of dopamine (Dopamine, HY-B0451) . Cotinine ((-) -Cotinine) is used in research related to cardiovascular and inflammatory diseases[1][2][3][4][5].
