Fabomotizole (also known as Afobazole) is a selective non-benzodiazepine anxiolytic which was developed in Russia and launched in 2006. The drug is used for the treatment of wide range of diseases: generalized anxious disorders, neurasthenia, adaptation disorders, sleep disorders, for alleviation of withdrawal syndrome. According to the drug label (in Russian), its action is related to the interaction with sigma-1 receptors.

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 GABAergicNGF– 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.

PAPER

European Journal of Medicinal Chemistry (2021), 211, 113110

https://www.sciencedirect.com/science/article/abs/pii/S0223523420310825?

A ligand-based virtual screening study to search for giardicidal compounds on a 6551 ChEMBL drugs database was carried out using molecular similarity. Three fingerprints implemented in MayaChemTools with different design and validated by ROC curves, were used. Twelve compounds were retrieved from this screening, from which, four representative compounds were selected to carry out biological assays. Whereas two compounds were commercially available, the additional two compounds were synthesized during the development of this work. The biological assays revealed that the compounds possess in vitro activity against five strains of Giardia intestinalis, each with different susceptibility/resistance rates to metronidazole, albendazole and nitazoxanide. Particularly, tenatoprazole showed the best effect against the WB and IMSS strains. Furthermore, fabomotizole, tenatoprazole and ipriflavone showed a higher activity against resistant strains than the reference drugs: metronidazole, albendazole and nitazoxanide.
