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

This work reports the experimental and computational thermochemical study performed on three difluorinated nitrobenzene isomers: 2,4-difluoronitrobenzene (2,4-DFNB), 2,5-difluoronitrobenzene (2,5-DFNB), and 3,4-difluoronitrobenzene (3,4-DFNB). The standard (p° = 0.1 MPa) molar enthalpies of formation in the liquid phase of these compounds were
