Fig. 2. Relative conversions of [¹⁸F]FAC-FDG-1 to [¹⁸F]FDG upon treatment with biologically relevant RCS and related molecules. Bars represent formation of FDG at 30 (light grey), 60 (grey), 120 (dark grey) and 180 (black) min after addition. Data shown are for 1 mM of all species unless otherwise noted and were acquired in 20 mM PBS (pH 7.4) at 37 °C. Legend: (1) FA (2) PBS (3) [¹⁸F]Ctrl-FAC-FDG plus 1 mM FA (4) acetaldehyde; (5) glucose; (6) sodium pyruvate; (7) benzaldehyde; (8) methylglyoxal; (9) methylglyoxal (10 μM); (10) dehydroascorbic acid; (11) glucosone; (12) H₂O₂.
