Mavoglurant, aslo known as AFQ056, is an experimental drug candidate for the treatment of fragile X syndrome. Mavoglurant exerts its effect as an antagonist of the metabotropic glutamate receptor 5 (mGLU5). Novartis discontinued development of mavoglurant for fragile X syndrome in April 2014 following disappointing trial results. Currently Novartis is conducting a clinical trial with this drug on obsessive compulsive disorder.

How to use

In Vitro:

Mavoglurant (1 nM-10 μM; 10 min) fully antagonizes hmGluR5-mediated responses with IC50s of 110 and 30 nM in Ca2+- and PI-turnover assays in L(tk-) cells stably expressing mGluR5a. Mavoglurant (0.01 nM-10 μM) displaces the binding of the allosteric binding ligand [3H]-AAE327 in a concentration-dependent manner in rat brain membranes, with an IC50 of 47 nM.

In Vivo:

Mavoglurant (0.1-10 mg/kg; a single p.o.) inhibits the stress-induced hyperthermia (SIH) in a dose-dependent manner in mice. Mavoglurant (9.4 mg/kg; a single p.o.) exhibits moderate oral bioavailability (32%), terminal half-life (2.9 h) and Cmax (plasma; brain) (950 pmol/mL; 3500 pmol/g). Mavoglurant (3.1 mg/kg; a single i.v.) exhibits terminal half-life (0.69 h), Cmax (plasma; brain) (3330 pmol/mL; 8400 pmol/g) and Tmax (≤0.08 h).
