The urinary mutagenicity (unconjugated forms) after administration of 2,7-dinitrofluorene (2,7-dNF) orally or i.p. was lower compared to 2-nitrofluorene (NF) administration. When partial hepatectomy (PH) was performed before i.p. administration, both substances had higher excretion of mutagens in which 2,7-dNF increased

Nitrofluorenes are mutagenic and carcinogenic environmental pollutants arising chiefly from combustion of fossil fuels. Nitro aromatic compounds undergo nitroreduction to N-hydroxy arylamines that bind to DNA directly or after O-esterification. This study analyzes the DNA binding and adducts from the

Environmental pollution with nitroaromatic compounds may pose health hazards. We have examined the tumorigenicity in female Sprague-Dawley rats of 2,7-dinitrofluorene (2,7-diNF) and 9-oxo-2,7-diNF administered by intraperitoneal (i.p.) and oral routes at 10 micromol/kg body weight, 3 times per week for
Nitrofluorene compounds are environmental pollutants chiefly from incomplete combustion. This study examined carcinogenicities after one intramammary injection of 2-nitrofluorene (2-NF), 2, 7-dinitrofluorene (2,7-diNF) or dimethyl sulfoxide (DMSO) (solvent control) to 30-day-old and of 2-NF, 9-OH-2-NF, 9-oxo-2-NF, 2,7-diNF, 9-oxo-2,7-diNF, 2,5-dinitrofluorene, 9-oxo-2,4,7-trinitrofluorene

Nitrofluorenes and C-9-oxidized nitrofluorenes are widespread environmental genotoxins which may be relevant for breast cancer on the basis of their carcinogenicities, particularly of 2, 7-dinitrofluorene (2,7-diNF), for the rat mammary gland. Since their metabolism to active carcinogens may involve nitroreduction
