Biological Activity

[Description]:

Etifoxine(HOE 36-801) is potentiator of GABAA receptor function in cultured neurons. Etifoxine preferentially acts on β2 or β3 subunit-containing GABAA receptors. IC50 value:Target: GABAA receptorEtifoxine exhibits anxiolytic activity in rodents and humans with no sedative, myorelaxant or mnesic side effects. Etifoxine acts as a ligand of the translocator protein (TSPO); promotes axonal regeneration.
