Electrochemical techniques provide valuable information about drug molecules and their mechanisms in the body such as metabolism, which is one of the important actions in drug discovery. Since, many physiological processes depend on oxido-reduction reactions, it is not difficult to find associations between electrochemical and biological reactions regarding electron transfers. To investigate this proposal two compounds namely 1-methylindole-3- carboxaldehyde izonicotinoyl hydrazone and 5-chloro-1H-indole-3-carboxaldehyde izonicotinoyl hydrazone were synthesized, characterized and examined electrochemically using different voltammetric techniques in order to evaluate the possible biological behavior. The characteristics of the corresponding electrode reaction were discussed. A linear response was obtained in the different media for the compounds with low detection limits of the synthesized compounds.
The aim of this study was to synthesize and examine possible in vitro antioxidant effects of indole-based melatonin analogue compounds. As a part of our ongoing study nineteen indole hydrazide/hydrazone derivatives were synthesized, characterized and their in vitro antioxidant activity was investigated by three different assays: by evaluating their reducing effect against oxidation of a redox sensitive fluorescent probe, by examining their protective effect against H2O2-induced membrane lipid peroxidation and by determining their inhibitory effect on AAPH–induced hemolysis of human erythrocytes. The results indicated significant strong antioxidant activity for most of the compounds, when compared to melatonin.
