Metabolite Identification
Common NameCarmofur
DescriptionCarmofur, also known as mifurol, 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. Based on a literature review a significant number of articles have been published on Carmofur. This compound has been identified in human blood as reported by (PMID: 31557052 ). Carmofur is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Carmofur 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.
