Biochem/physiol Actions
Fenobam is a potent, selective, noncompetitive glutamate mGluR5 receptor antagonist. Fenobam displays inverse agonist properties; blocks mGluR5 constitutive activity in vitro (IC50 = 87 nM, slightly weaker than MPEP). Fenobam acts at an allosteric modulatory site shared with MPEP and binds the mGlu5 receptor with Kd values of 54 and 31 nM for rat and human receptors, respectively. Fenobam belongs to a structurally different class than MPEP; devoid of GABAergic activity and thus typical benzodiazepine-like side effects; displays anxiolytic activity.

Fenobam [N-(3-chlorophenyl)-N'-(4,5-dihydro-1-methyl-4-oxo-1H-imidazole-2-yl)urea] was suggested to possess anxiolytic actions 30 years ago. Hoffmann-La Roche researchers recently reported that it is a selective and potent mGlu5 receptor antagonist, acting as a negative allosteric modulator. In the present study, we show that fenobam

Fenobam [N-(3-chlorophenyl)-N'-(4,5-dihydro-1-methyl-4-oxo-1H-imidazole-2-yl)urea], a clinically validated non-benzodiazepine anxiolytic, has been shown to be a potent and non-competitive metabotropic glutamate (mGlu)-5 receptor antagonist. In the present study, we have used the site-directed mutagenesis coupled with three-dimensional receptor-based pharmacophore modelling to elucidate the
1H- and 13C-NMR spectra of fenobam.

A pilot open label, single dose trial of fenobam, an mGluR5 antagonist, was conducted to provide an initial evaluation of safety and pharmacokinetics in adult males and females with fragile X syndrome (FXS). Twelve subjects, recruited from two fragile X

L-DOPA remains the gold-standard treatment for Parkinson's disease but causes motor fluctuations and dyskinesia. Metabotropic glutamate receptor type 5 (mGluR5) has been proposed as a target for antidyskinetic therapies. Here, we evaluate the effects of fenobam, a noncompetitive mGluR5 antagonist
