1,3-Butadiene (BD) is a carcinogenic air pollutant. Its bioactivation produces four major metabolites, i.e., 3,4-epoxy-1-butene (EB), 3,4-epoxy-1,2-butanediol (EBD), 1,2,3,4-diepoxybutane (DEB), and 3-butene-1,2-diol (BDD). Studies have been mostly focused on DEB due to its strong mutagenicity/carcinogenicity. In contrast, studies of genotoxicity

Three optical isomers of 1,2,3,4-diepoxybutane, S,S-, R,R-, and meso-diepoxybutane, are produced by the metabolic processing of carcinogenic 1,3-butadiene. Our previous studies suggested that the observed differences between the biological effects of diepoxybutane optical isomers may be structural in their origin.
