Abstract:

1-chloro-2-hydroxy-3-butene (CHB) is a metabolite of 1,3-butadiene, an environmental pollutant. CHB is cytotoxic, genotoxic, and mutagenic. H$_2$S is the third gasotransmitter following NO and CO, and is involved in a variety of physiological activities. Abnormal metabolism of H$_2$S is associated with many diseases. In the present study, the effect of CHB on the concentrations of endogenous H$_2$S in human hepatocyte L02 cells was investigated. It was observed that CHB could cause significant decreases in the concentrations of endogenous H$_2$S in the cells and the effect depended on CHB concentration. Thus, inhibition of endogenous H$_2$S production in cells by CHB may be a mechanism for toxicity of CHB, which can contribute to a better understanding of toxicity of 1,3-butadiene.

Key words: 1-chloro-2-hydroxy-3-butene (CHB), H$_2$S, 1,3-butadiene, toxicity
