title: Metabolic activation of 2-aminofluorene by isolated rat liver cells through different pathways leading to hepatocellular DNA-repair and bacterial mutagenesis.
abstract: The aromatic amine 2-aminofluorene (2-AF) is metabolised by isolated rat liver cells to reactive species, thereby causing mutagenic effects in Salmonella typhimurium TA 1538 and evoking DNA-excision repair within the liver cells. The pathway leading to the production of metabolites mutagenic in Salmonella is likely to proceed via direct N-hydroxylation of 2-AF to N-hydroxy-2-aminofluorene (N-OH-2-AF). On the other hand, the formation of intermediates giving rise to hepatocellular DNA-repair is shown to depend upon N-acetylation of 2-AF to 2-acetylaminofluorene(2-AAF), whereas a subsequent conjugation reaction, most likely to be sulfate ester formation, is also essentially involved.
