Metabolite Identification

Common Name

1-Ethoxymethyl-5-fluorouracil

Description

1-Ethoxymethyl-5-fluorouracil, also known as em-fu, 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 1-Ethoxymethyl-5-fluorouracil. This compound has been identified in human blood as reported by (PMID: 31557052 ). 1-ethoxymethyl-5-fluorouracil is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically 1-Ethoxymethyl-5-fluorouracil 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.
