Chemico-biological interactions, 98(2), 97-112 (1995-11-17)
Proximal tubular biotransformation of the glutathionyl (GSH) conjugate derived from 2,5-difluoronitrobenzene (5-fluoro-2-glutathionyl-nitrobenzene) was studied by means of 19F-NMR. This method allows a direct and specific detection of the fluorinated metabolites formed, at a detection limit of 1 microM for an

The in vivo metabolite patterns of 2,5-difluoroaminobenzene and of its nitrobenzene analogue, 2,5-difluoronitrobenzene, were determined using 19F NMR analysis of urine samples. Results obtained demonstrate significant differences between the biotransformation patterns of these two analogues. For the aminobenzene, cytochrome P450
