Sign in to saveAlso known as (S)-Cotinine, (S)-(-)-Cotinine, (S)-1-Methyl-5-(3-pyridinyl)-2-pyrrolidinone, (5S)-1-methyl-5-(3-pyridyl)-2-pyrrolidinone, (5S)-1-methyl-5-(3-pyridyl)pyrrolidin-2-one, (5S)-1-methyl-5-(3-pyridyl)-2-pyrrolidone, (5S)-1-methyl-5-pyridin-3-ylpyrrolidin-2-one, (5S)-1-methyl-5-pyridin-3-yl-pyrrolidin-2-one
Cotinine is an alkaloid found in tobacco and is also the predominant metabolite of nicotine, typically used as a biomarker for exposure to tobacco smoke. Cotinine is currently being studied as a treatment for depression, post-traumatic stress disorder (PTSD), schizophrenia, Alzheimer's disease and Parkinson's disease. Cotinine was developed as an antidepressant as a fumaric acid salt, cotinine fumarate, to be sold under the brand name Scotine, but it was never marketed.

Cotinine is an alkaloid found in tobacco and is also the predominant metabolite of nicotine, typically used as a biomarker for exposure to tobacco smoke. Cotinine is currently being studied as a treatment for depression, post-traumatic stress disorder (PTSD), schizophrenia, Alzheimer's disease and Parkinson's disease. Cotinine was developed as an antidepressant as a fumaric acid salt, cotinine fumarate, to be sold under the brand name Scotine, but it was never marketed.
Similarly to nicotine, cotinine binds to, activates, and desensitizes neuronal nicotinic acetylcholine receptors, though at much lower potency in comparison. It has demonstrated nootropic and antipsychotic-like effects in animal models. Cotinine treatment has also been shown to reduce depression, anxiety, and fear-related behavior as well as memory impairment in animal models of depression, post-traumatic stress disorder, and Alzheimer's disease. Nonetheless, treatment with cotinine in humans was reported to have no significant physiologic, subjective, or performance effects in one study, though others suggest that this may not be the case.
