Fluorine-18 labeled amino acids for tumor PET/CT imaging
Tumor glucose metabolism and amino acid metabolism are usually enhanced, 18F-FDG for tumor glucose metabolism PET imaging has been clinically well known, but tumor amino acid metabolism PET imaging is not clinically familiar. Radiolabeled amino acids (AAs) are an important class of PET/CT tracers that target the upregulated amino acid transporters to show elevated amino acid metabolism in tumor...
متن کاملSynthesis of fluorine-18 labeled GABA uptake inhibitors.
The first syntheses of fluorine-18 labeled inhibitors of GABA reuptake [(R,S)-1-[2-[4-[18F]fluorophenyl]phenyl]methoxyethyl]piperidine- 3-carboxylic acid, (R,S)-1-[2-[(4-[18F]trifluoromethyl)phenyl][(4- trifluoromethyl)phenyl]-methoxyethyl]piperidine-3-carboxylic acid] are described. These N-substituted nipecotic acid derivatives were prepared in no-carrier-added form by the condensation of the...

متن کاملBiodistribution and Elimination Study of Fluorine-18 Labeled Nε-Carboxymethyl-Lysine following Intragastric and Intravenous Administration
BACKGROUND N(ε)-carboxymethyl-lysine (CML) is a major advanced glycation end-product (AGEs) widely found in foods. The aim of our study was to evaluate how exogenous CML-peptide is dynamically absorbed from the gastrointestinal tract and eliminated by renal tubular secretion using microPET imaging. METHODS The present study consisted of three investigations. In study I, we synthesized the ima...
متن کاملProduction and Application of Synthetic Precursors Labeled with Carbon-n and Fluorine-18
Wfiout a doubt, the sueeess of PET as an imaging tool for bwic research in the Me sciences stems largely flom the effort and success of chemists over the years in developing suitable radiotracers. This success derives in part from the fhct that there exists today an extensive inventmy of synthetic precursors, or small mokxxdes labeled with short-Jived positron emitting radionuclides, that can b...
