ACPT-I is an agonist of the group III metabotropic glutamate receptors (mGluRs) mGluR4a and mGluR8 (EC50s = 7.2 and 8.2 µM, respectively) that has no effect on mGluR1a or mGluR2. It has diverse biological activity, including neuroprotective, anticonvulsant, and anxiolytic-like effects. ACPT-I (1-200 µM) reduces cell...

Felbamate is an inhibitor of NMDA receptors and a modulator of GABAA receptors that also has broad-spectrum inhibitory activity against excitatory amino acid receptors. It binds to NMDA channels with dissociation constants of approximately 200, 110, and 55 µM in the resting, activated, and desensitized states,...
