[3H]NAAG,N-acetyl-L-aspartyl-L-glutamic acid, has been widely used as a sub-strate in glutamate carboxypeptidase II (GCPII) reactions, either to determinethe inhibitory constants at 50% inhibition (IC50) of novel compounds or tomeasure GCPII activities in different tissues harvested from various diseasemodels. The importance of [3H]NAAG, combined with its current commercialunavailability, prompted the development of a reliable eight-step synthetic pro-cedure towards [3H2]NAAG starting from commercially available pyrogluta-mate. Pure [3H]NAAG of high molar activity (49.8 Ci/mmol) and desiredstereochemistry was isolated in high radiochemical yield (67 mCi) and radio-chemical purity (>99%). The identity was confirmed by mass spectrometry andco-injection with unlabeled reference.
