PRIMARY Selective glutamate carboxypeptidase II (GCP II) inhibitor (IC50 = 90 nM). Selective for GCP II over NMDA, kainate and AMPA glutamate receptors and MMP-1, -2, -3, -7, -9, ACE and NEP metalloproteases. Antinociceptive in a rat model of neuropathic pain and protects against motor neuron death in familial amyotrophic lateral sclerosis mice. Orally bioavailable.

ACTIVE MOIETY
We found that oral administration of GPI-5693 (15, 30, 60 mg/kg, p.o.) did not significantly alter intravenous cocaine self-administration under fixed-ratio (FR2) reinforcement, but significantly inhibited cocaine-induced reinstatement of the extinguished drug-seeking behavior. This inhibition was blocked by pretreatment with LY341495, a selective mGlu2/3 receptor antagonist. Two enantiomers of GPI-5693, also inhibited cocaine-induced reinstatement similar to GPI-5693.
ACTIVE MOIETY
