Effect of novel water-soluble phenolic antioxidants on cell viability: structure-activity relationships

Author Affiliations

Abstract

In order to investigate cytotoxicity of structurally similar synthetic water-soluble sulfur- and selenium-containing monophenolic antioxidants, their effect on the viability of monocyte/macrophage U937 cells has been studied in normal conditions and under oxidative stress. All tested compounds showed low toxicity (IC50 = 0.3 mM), with the exception of selenium-containing analog (IC50 = 80 mM). At that, partially hindered phenol with one ortho-tert-butyl and a bivalent sulfur atom in the para-propyl substituent TS-13 at low doses increased the number of viable cells in vitro in normal conditions and when incubated with the cytotoxic concentrations of H2O2, probably due to inhibition of the apoptotic processes.

Key words

TS-13, viability, synthetic antioxidants
