Metabolite Identification
Common Name2,4(1H,3H)-Pyrimidinedione, 5-fluoro-1-(tetrahydro-2-furanyl)-, (R)-
DescriptionTegafur, also known as atillon, belongs to the class of organic compounds known as halopyrimidines. These are aromatic compounds containing a halogen atom linked to a pyrimidine ring. Pyrimidine is a 6-membered ring consisting of four carbon atoms and two nitrogen centers at the 1- and 3- ring positions. Tegafur is a primary metabolite. Primary metabolites are metabolically or physiologically essential metabolites. They are directly involved in an organism’s growth, development or reproduction. Based on a literature review a significant number of articles have been published on Tegafur. This compound has been identified in human blood as reported by (PMID: 31557052 ). 2,4(1h,3h)-pyrimidinedione, 5-fluoro-1-(tetrahydro-2-furanyl)-, (r)- is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically 2,4(1H,3H)-Pyrimidinedione, 5-fluoro-1-(tetrahydro-2-furanyl)-, (R)- is part of the human exposome. The exposome can be defined as the collection of all the exposures of an individual in a lifetime and how those exposures relate to health. An individual's exposure begins before birth and includes insults from environmental and occupational sources.
