Until now, no data are available concerning the biotransformation and toxicity of 2-methylpropene (or isobutene), a gaseous alkene widely used in industry (rubber, fuel additives, plastic polymers, adhesives, antioxidants). In this work, the biotransformation of 2-methylpropene (MP) has been studied

Chemical research in toxicology, 8(7), 987-992 (1995-10-01)
The biotransformation of 2-methylpropene, a gaseous alkene widely used in industry, was investigated in vitro in liver tissue of rats, mice, and humans. Interspecies comparison revealed that the lowest levels of the primary epoxide metabolite were detected in incubations of

Protonated epoxides feature prominently in organic chemistry as reactive intermediates. Herein, we describe 10 protonated epoxides using B3LYP, MP2, and CCSD/6-311++G calculations. Relative to CCSD, B3LYP consistently overestimates the C2-O bond length. Protonated 2-methyl-1,2-epoxypropane is the most problematic species studied

Mutagenesis, 10(2), 101-104 (1995-03-01)
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-mutagenic in a modified Ames test, whereas the epoxide metabolite gave a positive result. In

Critical reviews in toxicology, 27(3), 223-232 (1997-05-01)
2-Methylpropene (MP) or isobutene is a gaseous chemical used on a large scale in the synthetic rubber industry. The present review covers the rather scarce literature on MP with respect to its metabolic fate and toxicity in laboratory animals and
