Ethylthiosulfanylate is alkyl ester of thiosulfoacid and belongs to the class of thiosulfonate compounds. Structurally, thiosulfonates are synthetic analogues of natural phytoncides. It is known that, natural organic sulfur-containing compounds are characterized by antioxidant and detoxification properties against heavy metals toxicity. Therefore, the purpose of the study was to investigate the influence of ethylthiosulfanylate, as a synthetic analogue of natural phytoncides, on the state of the pro/antioxidant system in the liver of laboratory rats exposed to Cr(VI). It was found that ethylthiosulfanylate exposure at a dose 100 mg/kg body weight daily for 14 days led to a decrease in the intensity of increasing of the lipid hydroperoxides (LHP) content in the rat liver caused by Cr(VI) action. In addition, ethylthiosulfanylate pretreatment prevented depletion of reduced glutathione (GSH) pool under the action of potassium dichromate oxidative stress and performed the accumulation of cellular GSH in rat liver.
