2-MPPA is a selective glutamate carboxypeptidase II (GCP-II) inhibitor used in the treatment of neurological disorders associated with excessive activation of glutamatergic systems. Attenuates glutamate transmission resulting in the relief of neuropathic pain.
PMPA is a potent inhibitor of the neuropeptidase N-acetylated α-linked acidic dipeptidase (NAALADase), which is a membrane-bound peptidase that hydrolyses N-acetyl-L-aspartate-L-glutamate (NAAG), a major brain peptide.
