General description

Cotinine is an alkaloid extracted from tobacco leaves. It can cross the blood-brain barrier. Cotinine is used to treat Alzheimer′s disease (AD), schizophrenia and post-traumatic stress disorder (PTSD).

Application

Cotinine has been used:
  • for oxygen-glucose deprivation (OGD) studies to model ischemic stroke
  • as a standard to determine serum cotinine measurements using liquid chromatography with tandem mass spectrometry (LC-MS/MS)
  • to evaluate the adverse developmental potential of cotinine
  • to assess cognitive behavior in mice

Biochem/physiol Actions

Major metabolite of nicotine in humans.
