Fabomotizole hydrochloride (CM346 hydrochloride), an anxiolytic drug, produces anxiolytic and neuroprotective effects. The mechanism of Afobazole remains poorly defined, however, with GABAergic, NGF, and BDNF release promoting, MT1 receptor antagonism, MT3 receptor antagonism, and sigma agonism suggested as potential mechanisms. Afobazole inhibits MAO-A reversibly and there might be also some involvement with serotonin receptors.
