4 Pharmacology and Biochemistry
4.1 Metabolism/Metabolites

5-Nitro-ortho-toluidine was identified as a product of the microbial transformation by Mucrosporium sp. of 2,4-dinitrotoluene, a compound common in water discharges and effluents from ammunition plants, ammunition loading facilities and sites for the destruction of stockpiled weapons ... . 5-Nitro-ortho-toluidine was identified as an intermediate in the anaerobic biotransformation of 2,4-dinitrotoluene added to a sample of municipal activated sludge ... . 5-Nitro-ortho-toluidine is formed enzymatically from 2,4-dinitrotoluene by liver and lung microsomal fractions from mice ... by liver microsomal and cytosolic fractions from rats ... and by intestinal microorganisms from rats and mice ... . 5-Nitro-ortho-toluidine and its N-acetyl derivative were identified as minor metabolites of 2,4-(14)C-dinitrotoluene when this compound was administered orally to male and female Fischer 344 rats at doses of 35, 63 or 100 mg/kg bw ... . Human intestinal microflora catalyse the reductive metabolism of 2,4-dinitrotoluene to 5-nitro-ortho-toluidine and 4-amino-2-nitrotoluene via nitroso intermediates ... .
