title: Enhancement of mutagenicity by hydroxypyrenes in Salmonella.
abstract: 1-Hydroxypyrene and 4,5-dihydro-4,5-dihydro-4,5-dihydroxypyrene were isolated and identified in the metabolites of pyrene by rat liver microsomal fraction, and the presence of 1,8- and 1,6-dihydroxypyrene in the metabolites was proposed. These hydroxypyrenes, as well as pyrenequinones reported previously, enhanced intensively the mutagenicity of 2-acetylaminofluorene (AAF).
