Metabolite Identification
Common Name3-Fluoro-5-[(pyridin-3-yl)ethynyl]benzonitrile
Description3-Fluoro-5-[(pyridin-3-yl)ethynyl]benzonitrile, also known as (18F)F-peb, belongs to the class of organic compounds known as benzonitriles. These are organic compounds containing a benzene bearing a nitrile substituent. Based on a literature review a significant number of articles have been published on 3-Fluoro-5-[(pyridin-3-yl)ethynyl]benzonitrile. This compound has been identified in human blood as reported by (PMID: 31557052 ). 3-fluoro-5-[(pyridin-3-yl)ethynyl]benzonitrile is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically 3-Fluoro-5-[(pyridin-3-yl)ethynyl]benzonitrile 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.
