Afobazole from Russia

Fabomotizole (INN;[1] brand name Afobazole) is an anxiolytic drug launched in Russia in the early 2000s. It produces anxiolytic and neuroprotective effects without any sedative or muscle relaxant actions.[citation needed] Its mechanism of action remains poorly defined however, with GABAergic, NGF- and BDNF-release-promoting, MT1 receptor agonism, MT3 receptor antagonism, and sigma agonism suggested as potential mechanisms. Fabomotizole was shown to inhibit MAO-A reversibly and there might be also some involvement with serotonin receptors.[2][3][4][5][6] Clinical trials have shown fabomotizole to be well tolerated and reasonably effective for the treatment of anxiety.[7]

Experiments of mice have shown antimutagenic and antiteratogenic properties.[8]

Fabomotizole has found little clinical use outside Russia and has not been evaluated by the FDA.
