The 2-[(3-carboxy-1-oxopropyl) amino]-2-deoxy-D-glucose (CPADG) was synthesized and radiolabeled with (TcO4)-Tc-99m to obtain the Tc-99m-CPADG complex in high yield. It was stable over 6 h in saline at room temperature and in serum at 37 degrees C. The partition coefficient and electrophoresis results indicated that the complex was hydrophilic and cationic. In vitro cell studies showed there was an increase in the uptake of Tc-99m-CPADG as a function of incubation time and Tc-99m-CPADG was possibly transported via the glucose transporters. The biodistribution of Tc-99m-CPADG in mice bearing S 180 tumor showed that the complex accumulated in the tumor with high uptake and good retention. The tumor/blood and tumor/muscle ratios increased with time and reached 1.91 and 5.05 at 4 h post-injection. Single photon emission computed tomography (SPECT) image studies showed there was an obvious accumulation in tumor sites, suggesting Tc-99m-CPADG would be a promising candidate for tumor imaging.
