Fenobam is a selective non-competitive antagonist of the mGluR-5 receptor (metabotropic glutamate receptor subtype 5). This compound is described to act at an allosteric modulatory site on mGluR-5 common with MPEP (sc-215392), producing inverse agonist activity. Interaction of Fenobam at mGluR-5 is correlated to anxiolytic effects.
