Metabolite Identification
Common Name2-[2-(3-Methoxyphenyl)ethynyl]-6-methylpyridine
Description2-[2-(3-Methoxyphenyl)ethynyl]-6-methylpyridine belongs to the class of organic compounds known as anisoles. These are organic compounds containing a methoxybenzene or a derivative thereof. Based on a literature review very few articles have been published on 2-[2-(3-Methoxyphenyl)ethynyl]-6-methylpyridine. This compound has been identified in human blood as reported by (PMID: 31557052 ). 2-[2-(3-methoxyphenyl)ethynyl]-6-methylpyridine is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically 2-[2-(3-Methoxyphenyl)ethynyl]-6-methylpyridine 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.
