    por Van Duuren, B L
    Publicado 1977
    “…Other work reviewed here concerns the synthesis of TCE epoxide and its reaction with nucleophiles since it is believed that TCE epoxide is the activated carcinogenic intermediate of TCE. The utility of structural prognostication of carcinogenic activity and the importance of considering possible metabolic pathways for other chlorinated olefins is also discussed.…”

    Publicado 1979
    “…The small intestinal surface is more a portal than a barrier, with its portal functions divided between nonspecific diffusional entry, which depends on physical properties and electric charge, and entry by specific membrane transport, which depends upon chemical structure. The implications of these properties of the small intestine for toxicological studies are stressed.…”
