Reactivity in vivo of the carcinogen N-hydroxy-2-acetylaminofluorene: increase by sulfate ion. 1970

J R DeBaun, and J Y Smith, and E C Miller, and J A Miller

Injections of sulfate ion in rats given the carcinogen N-hydroxy-2-acetylaminofluorene increased (i) the formation of 1-and 3-(methion-S-yl)-2-acetylaminofluorene bound to protein in the liver, (ii) the formation of fluorenyl derivatives bound to total protein, ribosomal RNA, and DNA in the liver, and (iii) the toxicity of the carcinogen. These data provide evidence that the highly reactive ester 2-acetylaminofluorene-N-sulfate, previously suggested as an ultimate reactive and carcinogenic metabolite of N-hydroxy-2-acetylaminofluorene, is formed in the rat liver in vivo.

UI MeSH Term Description Entries
D007267 Injections Introduction of substances into the body using a needle and syringe. Injectables,Injectable,Injection
D008099 Liver A large lobed glandular organ in the abdomen of vertebrates that is responsible for detoxification, metabolism, synthesis and storage of various substances. Livers
D008297 Male Males
D011485 Protein Binding The process in which substances, either endogenous or exogenous, bind to proteins, peptides, enzymes, protein precursors, or allied compounds. Specific protein-binding measures are often used as assays in diagnostic assessments. Plasma Protein Binding Capacity,Binding, Protein
D002273 Carcinogens Substances that increase the risk of NEOPLASMS in humans or animals. Both genotoxic chemicals, which affect DNA directly, and nongenotoxic chemicals, which induce neoplasms by other mechanism, are included. Carcinogen,Oncogen,Oncogens,Tumor Initiator,Tumor Initiators,Tumor Promoter,Tumor Promoters,Initiator, Tumor,Initiators, Tumor,Promoter, Tumor,Promoters, Tumor
D005449 Fluorenes A family of diphenylenemethane derivatives.
D005463 Fluoroacetates Derivatives of acetic acid with one or more fluorines attached. They are almost odorless, difficult to detect chemically, and very stable. The acid itself, as well as the derivatives that are broken down in the body to the acid, are highly toxic substances, behaving as convulsant poisons with a delayed action. (From Miall's Dictionary of Chemistry, 5th ed)
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
