Metabolite Identification
Common Name6-Hydroxy-5-fluorocytosine
Description6-Hydroxy-5-fluorocytosine 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 very few articles have been published on 6-Hydroxy-5-fluorocytosine. This compound has been identified in human blood as reported by (PMID: 31557052 ). 6-hydroxy-5-fluorocytosine is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically 6-Hydroxy-5-fluorocytosine 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.
