Abstract/OtherAbstract:
1. Pyrene metabolite g.l.c. profiles were recorded and metabolites identified by mass spectrometry. 2. Pyrene is metabolized by liver microsomes of untreated rats to 1-hydroxypyrene, 4,5-dihydroxy-4,5-dihydropyrene, two different diphenols and a triol, tentatively identified as 1,4,5-trihydroxy-4,5-dihydropyrene. 3. Pretreatment with phenobarbital or polychlorinated biphenyls favours oxidation at the K-region, whereas cytochrome P-448 inducers stimulate oxidation at the non-K-region of pyrene. 4. 1-Hydroxypyrene does not inhibit pyrene oxidation. 5. Pyrene diphenols are formed by secondary oxidation of 1-hydroxypyrene. 6. Triols are formed from dihydrodiols by secondary oxidation.
