fenobam

Fenobam shows inverse agonist activity which blocks the mGlu5 receptor basal activity(IC50: 84 nM). Fenobam has anxiolytic activity. Fenobam is a selective and non-competitive mGluR5 antagonist acting at an allosteric modulatory site (Kd values are 54 and 31 nM for rat and human recombinant mGlu5 receptors, respectively).

Fenobam hydrate is a noncompetitive antagonist and inverse agonist of metabotropic glutamate receptor 5 (mGluR5). It inhibits intracellular calcium mobilization induced by the glutamate analog quisqualate and inhibits basal activity of mGluR5. Fenobam reduces stress-induced hyperthermia, exhibits anxiolytic-like activity, and may induce analgesia.
