Metabolic activation and mutagenicity of 4 vinylic monomers (vinyl chloride, styrene, acrylonitrile, butadiene). 1981

M Duverger, and M Lambotte, and E Malvoisin, and C de Meester, and F Poncelet, and M Mercier

The mutagenic activity and the metabolism of four vinylic monomers; vinyl chloride, styrene, acrylonitrile and butadiene are reviewed. Those chemicals are converted by the mixed function oxidases system of the endoplasmic reticulum into reactive intermediates which can interact with macromolecules within the cell. In order to examine the mutagenic activity of these compounds and their metabolites, different mutagenicity testing systems have been used: tests with S. typhimurium, E. coli, Schizosaccharomyces pombe, Saccharomyces cerevisiae, V79 Chinese Hamster cells, CHO cells, Drosophila melanogaster as well as evaluations of chromosome aberrations.

D000181 Acrylonitrile A highly poisonous compound used widely in the manufacture of plastics, adhesives and synthetic rubber. Vinyl Cyanide,Cyanide, Vinyl
D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA. Animal,Metazoa,Animalia
D001711 Biotransformation The chemical alteration of an exogenous substance by or in a biological system. The alteration may inactivate the compound or it may result in the production of an active metabolite of an inactive parent compound. The alterations may be divided into METABOLIC DETOXICATION, PHASE I and METABOLIC DETOXICATION, PHASE II.
D013343 Styrenes Derivatives and polymers of styrene. They are used in the manufacturing of synthetic rubber, plastics, and resins. Some of the polymers form the skeletal structures for ion exchange resin beads.
