Interconversion of 2-deoxy-2-fluoro-D-glucose (FDG) and 2-deoxy-2-2-fluoro-D-mannose (FDM) catalyzed by acid has been detected by 19F-NMR method. Although FDG and FDM were stable towards 1 N hydrochloric acid, in stronger acidic media the two hexoses underwent epimerization at C-2.

The metabolic products of 2-deoxy-2-fluoro-D-glucose (FDG) and 2-deoxy-2-fluoro-D-mannose (FDM) in sarcoma 180 cells transplanted in mice were investigated by fluorin-19 nuclear magnetic resonance (19F-NMR) spectroscopy. It became apparent that the administered FDG was converted to FDM (and/or FDM-6-phosphate) in tumor cells, and also the administered FDM was converted to FDG (and/or FDG-6-phosphate). At 9h after administration of FDM, the ratio of FDG (and/or FDG-6-phosphate) and FDM (and/or FDM-6-phosphate) reached equilibrium. On the other hand, it took more than 48h in the case of FDG administration. The equilibrium amount of FDM (and/or FDM-6-phosphate) was approximately four times as much as that of FDG (and/or FDG-6-phosphate) in both cases.
