Synthesis and biological evaluation of technetium-99m-labeled deoxyglucose derivatives as imaging agents for tumor.

Key Laboratory of Radiopharmaceuticals (Beijing Normal University), Ministry of Education, College of Chemistry, Beijing Normal University, Beijing 100875, PR China.

Three deoxyglucose (DG) derivatives, S-DG, MAG(3)-DG and MAMA-BA-DG, were synthesized and labeled successfully with high labeling yields and high radio-chemical purities. Biodistribution in tumor-bearing mice demonstrated that these three new (99m)Tc-deoxyglucose derivatives showed accumulation in tumor and high tumor-to-muscle ratios. Among them, the (99m)Tc-MAG(3)-DG showed the best characteristics as a potential tumor marker for single photon emission computed tomography (SPECT).
