1. After administration of 2,4-diaminotoluene to rabbits, rats and guinea-pigs, phenolic metabolites are excreted, the major component being 5-hydroxy-2,4-diaminotoluene in all species investigated. Acetylated aminophenols and glucuronide conjugates were also found. 2. Rabbits, which produced the largest amounts of free amino-phenols, also had the highest levels of methaemoglobin in vivo.
Within 48 h of administration of radiolabelled 10-formylfolate, folic acid and the polyglutamate derivative 10-formylfolate tetraglutamate to the rat, fragmentation products are found in the urine. The major catabolite was identified as p-acetamidobenzoate by chromatography and reverse isotope-dilution analysis.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
