Background:

IC50: 2.4 nM


ZJ-43 is a N-acetylaspartylglutamate (NAAG) peptidase inhibitor.


The peptide neurotransmitter N-acetylaspartylglutamate (NAAG) is reported to act as an agonist at group II metabotropic glutamate receptors. NAAG is inactivated by extracellular peptidase activity leading to yielding glutamate and N-acetylaspartate.


In vitro: As a potent inhibitor of glutamate carboxypeptidase II and III (GCP II and III) with Kivalues of 0.8 and 23 nM respectively, ZJ-43 inhibited the hydrolysis of NAAG via indirect interactions with NMDA or metabotropic glutamate receptors [1].


In vivo: Intravenous injection of ZJ-43 coiuld suppress both phases of the agitation behaviour induced by paw formalin injection in the rat neuropathic pain model. Moreover, intravenous administration of ZJ-43 attenuated the level of mechanical allodynia induced by the nerve ligation. These effects of ZJ-43 in both the formalin test and the partial sciatic nerve ligation model were completely antagonized by pretreatment with LY-341495, which was a highly selective group II mGluR antagonist [1].


Clinical trial: N/A
