Metabolite Identification
Common Name6-exo-Hydroxyfenchone
Description6-exo-Hydroxyfenchone belongs to the class of organic compounds known as bicyclic monoterpenoids. These are monoterpenoids containing exactly 2 rings, which are fused to each other. 6-exo-Hydroxyfenchone was found to be an oxidation product of both (+)-fenchone and (-)-fenchone by two human liver microsomal P450 enzymes: CYP2A6 and CYP2B6 (PMID: 17142962 , 17484521 ).
