Mutagenicity of 2-methylpropene (isobutene) and its epoxide in a modified Salmonella assay for volatile compounds.

Mutat. Res. 271(3) , 213-21, (1992)

The mutagenic properties of 2-methylpropene (MP) and 2-methyl-1,2- epoxypropane (MEP) were investigated in the Salmonella assay. A simple exposure system, consisting of gastight tissue culture flasks,...

Comparative mutagenicity of 2-methylpropene (isobutene), its epoxide 2-methyl-1,2-epoxypropane and propylene oxide in the in vitro micronucleus test using human lymphocytes.

Mutagenesis 10(2) , 101-4, (1995)

2-Methylpropene (isobutene), a gaseous compound widely used in chemical industries, is metabolized to the epoxide 2-methyl-1,2-epoxypropane. The parent compound has previously been shown to be non-mut...
