The mutagenicity and activation requirements of purified synthetic derivatives and potential metabolites of 1-nitropyrene have been characterized in the Ames plate incorporation assay with the Salmonella tester strains TA98, TA98NR and TA98/1,8-DNP6, in the presence or absence of exogenous metabolic activation provided by Aroclor-induced rat liver S9. All the compounds tested (1-aminopyrene, N-acetyl-1-aminopyrene, N-hydroxy-N-acetyl-1-aminopyrene, 3-hydroxy-1-nitropyrene, 6-hydroxy-1-nitropyrene, and 8-hydroxy-1-nitropyrene) exhibited mutagenic activity under one or more assay conditions. 1-Nitropyrene was metabolized to 3-hydroxy-1-nitropyrene, 6- or 8-hydroxy-1-nitropyrene, 1-aminopyrene, N-acetyl-1-aminopyrene and other unidentified products (including some bound to protein) by an S9 preparation analogous to that used for exogenous metabolic activation in the Ames assay. 1-Nitropyrene and 3-hydroxy-1-nitropyrene were activated primarily by the 'classical' nitroreductase, while the other compounds, particularly in the presence of S9 metabolic activation, were dependent on transesterification for expression of their mutagenicity.
