Description

(+)-Fenchone, a bicyclic monoterpene, is widely distributed in plants and found in essential oils from Foeniculum vulgare. This component has camphoraceous fragrance. (+)-Fenchone is used as a food flavour and in perfumes. Although, there are report that (+)-fenchone has toxic. P450 enzymes are shown to detoxify and/or toxify these compounds to metabolites more polar and sometimes more reactive metabolites. (+)-fenchone are oxidized to 6-endo-hydroxyfenchone, 6-exo-hydroxyfenchone and 10-hydroxyfenchone derivatives in human liver microsomes. CYP2A6 is suggested to be a principal enzyme in catalyzing (+)-fenchone 6-exo and 6-endo hydroxylation by human liver microsomes. 10-Hydroxylation of (+)-fenchone is also metabolized by CYP2B6.

(+)-Fenchone hydroxylation activities by P450 enzymes were determined as follows. Standard reaction mixture contained human liver microsomes (0.1 mg/ml) or recombinant P450 (10 pmol/ml) with 100 uM concentration of (+)-fenchone in a final volume of 0.5 ml of 100 mM potassium phosphate buffer (pH 7.4) containing an NADPH-generating system consisting of 0,5 mM NADP+, 5 mM glucose 6-phosphate, and 0.5 unit of glucose 6-phosphate dehydrogenase/ml. The organic phase was transferred to an insert for analysis by gas chromatography-mass spectrometry. CYP2A6 and CYP2B6 in human liver microsomes were major enzymes involved in the hydroxylation of (+)-fenchone.
