Metabolite Identification
Common Name2,6-Dihydroxy-3-cyanopyridine
Description2,6-Dihydroxy-3-cyanopyridine, also known as 2,6-CNDP or 3-cyano-2,6-dihydroxypyridine, belongs to the class of organic compounds known as 3-pyridinecarbonitriles. These are organic compounds containing a pyridine ring substituted at the 3-position by a carbonitrile group. Based on a literature review very few articles have been published on 2,6-Dihydroxy-3-cyanopyridine. This compound has been identified in human blood as reported by (PMID: 31557052 ). 2,6-dihydroxy-3-cyanopyridine is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically 2,6-Dihydroxy-3-cyanopyridine 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.
