The mutagenicity of 2,3- epoxybutane (2,3-EB) towards Salmonella FFphimurium TA1530 is increased by rat liver S9 mix. This enhancement can be induced by Aroclor 1254 (ARO) or phenobarbitone (PB) pretreatment. Comparative assays with purified subcellular liver fractions demonstrated that cytosol

The compound 2,3-epoxybutane (2,3-EB) is a direct mutagen for the base-pair-substitution-sensitive strains TA 1530, TA 1535 and TA 100, in the absence and in the presence of metabolic activation by liver S9-mix. Under the same experimental conditions, the 2-methyl derivative
P Castelain et al.

Four structurally related aliphatic epoxides (1,2-epoxypropane, 1,2-epoxyisobutane, cis- and trans-2,3-epoxybutane) have been tested in the Salmonella/microsome assay, modified for volatile substances, using the strains TA1535 and TA100. The aim of the study was to evaluate the effect of methylation on
