Biochem/physiol Actions

Potent glutamate carboxypeptidase II (GCPII; NAAG peptidase; NAALADase I; PSMA) inhibitor that suppresses PCP-induced motor activity in vivo.
ZJ43 is a urea-based N-acetylaspartylglutamate (NAAG) analog and a potent glutamate carboxypeptidase II (GCPII; NAAG peptidase; N-acetylaspartylglutamate peptidase I; NAALADase I; prostate-specific membrane antigen; PSMA) inhibitor (Ki = 0.8 nM/hGCPII vs 23 nM/hGCPIII) with no affinity toward NMDAR or mGluRs. ZJ43 effectively suppresses phencyclidine-induced motor activity (150 mg ZJ43/kg, 10 mg PCP/kg i.p.) and displays antinociceptive efficacy (100 mg/kg i.v.) in rats in vivo. Comparing to Quisqualate and 2-PMPA, ZJ43 shows human species-selectivity over murine GCPII (Ki = 0.58 nM/h vs. 5.9 nM/m using respective avi-tagged extracellular GCPII).

Glutamate carboxypeptidase II (GCPII) inactivates the peptide neurotransmitter N-acetylaspartylglutamate (NAAG) following synaptic release. Inhibitors of GCPII increase extracellular NAAG levels and are efficacious in animal models of clinical disorders via NAAG activation of a group II metabotropic glutamate receptor. mGluR2

N-acetylaspartylglutamate (NAAG) is the third most prevalent and widely distributed neurotransmitter in the mammalian nervous system. NAAG activates a group II metabotropic glutamate receptor (mGluR3) and is inactivated by an extracellular enzyme, glutamate carboxypeptidase II (GCPII) in vivo. Inhibitors of this

(68)Ga-labeled, low-molecular-weight imaging agents that target the prostate-specific membrane antigen (PSMA) are increasingly used clinically to detect prostate and other cancers with positron emission tomography (PET). The goal of this study was to compare the pharmacokinetics of three PSMA-targeted radiotracers:

Traumatic brain injury (TBI) produces a rapid and excessive elevation in extracellular glutamate associated with excitotoxicity and secondary brain pathology. The peptide neurotransmitter Nacetylaspartylglutamate (NAAG) suppresses glutamate transmission through selective activation of presynaptic Group II metabotropic glutamate receptor subtype 3
