The process of studying free radicals began in the middle of the last century (the free radical theory of aging in 1956). Multiple studies have revealed the effect of free radicals on the cells of the body and the development of various diseases, such as diabetes, autoimmune diseases, diseases of the nervous system, and others. As a result, the term antioxidant has emerged, compounds that reduce and prevent the effects of free radicals.

A series of 4-(4-substituted benzylideneamino)-5-phenyl-4H-1,2,4-triazole-3-thiols (IVa-e) was obtained by reaction of 4-(amino)-5-phenyl-4H-1,2,4-triazole-3-thiol with aromatic aldehyde in presence of concentrated sulphuric acid. The synthesised compounds were characterized by FT-IR, 1H-NMR and mass spectra data. The compounds (IVa-e) were screened for their antianxiety activity. Among the compounds, IVa and IVe were found to be the most acitive antianxiety compounds.
