ZJ 43

Biological Activity

ZJ 43 is a potent inhibitor of glutamate carboxypeptidase II and III (GCP II and III/NAAG peptidase/NAALADase) (K_i values are 0.8 and 23 nM respectively) that inhibits the hydrolysis of NAAG (IC₅₀ = 2.4 nM). Does not directly interact with NMDA or metabotropic glutamate receptors. Reduces neuronal degeneration in a rat model of traumatic brain injury (TBI) and reduces locomotor activity in the PCP-model of schizophrenia.
