Metabolite Identification
Common Name3-N-(2-Fluoroethyl)spiperone
Description3-N-(2-Fluoroethyl)spiperone, also known as 18F-fesp, belongs to the class of organic compounds known as alkyl-phenylketones. These are aromatic compounds containing a ketone substituted by one alkyl group, and a phenyl group. Based on a literature review very few articles have been published on 3-N-(2-Fluoroethyl)spiperone. This compound has been identified in human blood as reported by (PMID: 31557052 ). 3-n-(2-fluoroethyl)spiperone is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically 3-N-(2-Fluoroethyl)spiperone 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.
