Benz[A]anthracene-7-methanol
CAS :Benz[A]anthracene-7-methanol is a cytosolic carcinogen that is metabolized by the liver to form benz[a]anthracene-7,8-epoxide. This metabolite binds to DNA and causes mutations in the genes, which leads to cancer. The hydroxyl group of this compound reacts with epidermal growth factor, causing an increase in the number of liver cells that can cause cancer. Benz[A]anthracene-7-methanol also interacts with reactive oxygen species and stimulates the production of growth factors like epidermal growth factor, which promote skin cell growth. It has been shown that benz[A]anthracene-7-methanol promotes tumorigenesis in CD1 mice and induces tumor formation in rat liver microsomes.Formule :C19H14ODegré de pureté :Min. 95%Masse moléculaire :258.3 g/mol(S)-(-)-2-Aminomethyl-1-ethylpyrrolidine
