N-(Deoxyguanosin-8-yl)-2-aminopyrene and N-(deoxyadenosin-8-yl)-2-aminopyrene were formed from metabolism of 2-nitropyrene (2-NP) in vitro and in vivo. The effects of dietary restriction (DR) and age on the formation of these DNA adducts were studied

We have characterized the DNA adducts of a series of nitro-polycyclic aromatic hydrocarbons (nitro-PAHs) formed under anaerobic conditions in vitro. Although the DNA adducts of nitro-PAHs formed through enzymatic nitroreduction are generally the C8-d

32 P-Postlabeling-HPLC is a highly sensitive analytical method for identification of chemical-modified DNA adducts isolated from samples obtained from experimental animals or humans exposed to carcinogenic chemicals. To determine optimal 32 P-postlab

1-Nitropyrene, the most abundant nitro-polycyclic aromatic hydrocarbon in the environment, is a known mammalian and bacterial mutagen and a tumorigen in animals. Early studies on DNA adduct characterization for 1-nitropyrene identified N-(deoxyguanos

We recently reported that the reaction of N-hydroxy-3-aminobenzo[a] pyrene with calf thymus DNA produced 6-(deoxyguanosin-N2-yl)-3-aminobenzo[a]pyrene as the predominant adduct. The deoxyguanosinyl group of this adduct resides at the C6 position, whi

We have been interested in the structure-activity relationships of nitro-polycyclic aromatic hydrocarbons (nitro-PAHs), and have focused on the correlation of structural and electronic features with biological activities, including mutagenicity and t

In vivo studies of the metabolic activation of 2-nitrofluoranthene (2-NFA) were conducted by incubating Salmonella typhimurium TA98 suspension cultures with 2-NFA (10 or 20μM) for 4 hr. The DNA was isolated and the resulting DNA adducts were analyze

2-Nitrobenzo[a]pyrene (2-nitro-BaP) induced 100% liver tumor incidence in the neonatal mouse tumorigenicity assay and exhibited the highest mutagenicity among the 1-, 2-, 3-, and 6-nitro-BaP when tested in Salmonella typhimurium TA98 and TA100. To de

We have studied in vitro metabolism, DNA adduct formation, mutagenicity, and tumorigenicity of a series of nitro−polycyclic aromatic hydrocarbons. The emphasis has been focused on the isomeric nitrobenzo−[a]pyrenes and related compounds. We have
