title: Biotransformation of 1-nitropyrene and 2-nitrofluorene to novel metabolites, the corresponding formylamino compounds, in animal bodies.
abstract: The present study provides the first evidence that nitropolycyclic aromatic hydrocarbons such as 1-nitropyrene and 2-nitrofluorene are metabolized to the corresponding formylamino compounds in animal bodies. The study shows that the formation of such novel metabolites, 1-formylaminopyrene and 2-formylaminofluorene, is due to N-formylation of the nitroreduction products, 1-aminopyrene and 2-aminofluorene, by liver formamidase in the presence of N-formyl-L-kynurenine.
