Popis: | 3-Nitrobenzo [a] pyrene (3-nitro-BaP) is a potent mutagenic environmental contaminant, and its biological activities have been intensively studied. It is significant to prepare its reactive metabolites and the corresponding modified DNA adducts for biological studies. The synthesis of its oxidized prorimate metabolite trans-7,8-dihydroxy-7,8-dihydro-3-nitrobenzo[a]pyrene (3-nitro-BaP-trans-7,8-dihydrodiol, 1), its oxidized ultimate metabolite trans-7,8-dihydroxy-anti-9,10-epoxy-7,8,9,10-tetrahydro-3-nitrobenzo[a]pyrene (3-nitro-BaP-DE, 2), and the corresponding DNA adduct 10-(deoxyguanosin-N 2 -yl)-7,8,9-trihydroxy-7,8,9,10-tetrahydro-3-nitrobenzo [a] pyrene is described |
