NCI Drug Dictionary


fluorine F 18 4-L-fluoroglutamine (2S,4R) 
A radioconjugate and glutamine analog consisting of the fluorine F 18 labeled 2S, 4R stereoisomer of 4-fluoroglutamine with potential use as a metabolic tracer for tumor imaging. Upon intravenous administration, fluorine F 18 4-L-fluoroglutamine (2S,4R) is preferentially taken up by cancer cells, possibly driven by c-Myc upregulation. Upon positron emission tomography (PET), cancer cells can be imaged. Tumor cells use the amino acid glutamine for nutritional purposes necessary for energy production and growth; as tumor cells proliferate more rapidly than normal healthy cells, glutamine uptake is higher in certain cancer cells. Check for active clinical trials or closed clinical trials using this agent. (NCI Thesaurus)
