Metabolite Identification

Common Name

Naphthalene epoxide

Description

Naphthalene epoxide is an epoxide derivative of naphthalene. The toxicity of naphthalene has to do with the Phase I metabolism of this compound by cytochrome P450 monooxygenases. Deactivation of naphthalene involves epoxidation followed by glutathione conjugation and mercapturic acid formation. Naphthalene is stereoselectively metabolized to form (1R,2S)-Naphthalene epoxide and (1S,2R)-Naphthalene epoxide in the presence of CYP1A1 and CYP1A2, CYP2E1,CYP3A4 and CYP2A6. (PMID: 16959878 ).
