1 Metabolism by CYP3A4 is only known for dihydrodiol metabolites of PAH but not for their parent compounds. trans-1,2-dihydro-1,2-naphthalenediol cytochrome P450 family 3 subfamily A member 4 Homo sapiens
2 In the present study, a CYP3A4 reporter gene assay, requiring the overexpression of PXR, was used to investigate whether the PAH parent compounds BaP, benzo[c]phenanthrene (BcP) and dibenzo[a,l]pyrene (DBalP) as well as their corresponding phase I metabolites, the respective dihydrodiols and diol epoxides, can induce CYP3A4 promoter activity. trans-1,2-dihydro-1,2-naphthalenediol cytochrome P450 family 3 subfamily A member 4 Homo sapiens
3 BaP, BcP and their dihydrodiols were found to significantly activate the CYP3A4 promoter. trans-1,2-dihydro-1,2-naphthalenediol cytochrome P450 family 3 subfamily A member 4 Homo sapiens
