“…Moreover, the comparatively higher E HOMO value of TMB indicates that its oxidation is relatively easier and this result is consistent with the low oxidation potential of this compound obtained from CV and DPV experiments. 56 Cytotoxicity analysis and antioxidant activity.-Before exploring the biological applications of the selected compounds, their cytotoxic effect on Hela cancer cell lines was examined through sulforhodamine B (SRB) assay. 69,70 This assay gives a sensitive index of cellular protein as SRB has the ability of binding to the basic amino acids of proteins.…”

Electrochemical behavior of three biologically important triazole and phenol containing Schiff bases (E)-3-((4H-1,2,4 triazol-4ylimino) methyl)benzene-1,2-diol (TMB), (E)-3-((4H-1,2,4 triazol-4-ylimino) methyl)para-phenol (p-TMP) and (E)-3-((4H-1,2,4 triazol-4-ylimino) methyl)ortho-phenol (o-TMP) were investigated by electrochemical, spectroscopic and computational methods. The peak potential of all the three compounds showed a linear dependence on pH under acidic conditions, but under alkaline conditions, electron transfer was not coupled to proton transfer. The acid-base dissociation constant (pKa) values of the compounds were evaluated both by electrochemical and UV-Vis spectroscopic techniques. On the basis of experimental and theoretical findings, redox mechanisms of the compounds were proposed and certain important kinetic and thermodynamic parameters were determined from their temperature and pH responsive redox response. Our studies showed a) low cytotoxicity for all three triazoles and b) antioxidant properties of these triazoles. TMB was found as the most promising antioxidant, which makes this compound interesting as a basis for further development as food supplement.
