Metabolite Identification
Common Name1-Methyl-4-phenyl-1,2,3,6-tetrahydropyridine
Description1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine, also known as MPTP, belongs to the class of organic compounds known as hydropyridines. Hydropyridines are compounds containing a hydrogenated pyridine ring (i.e. containing less than the maximum number of double bonds.). 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine is a primary metabolite. Primary metabolites are metabolically or physiologically essential metabolites. They are directly involved in an organism’s growth, development or reproduction. Based on a literature review a small amount of articles have been published on 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine. This compound has been identified in human blood as reported by (PMID: 31557052 ). 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically 1-Methyl-4-phenyl-1,2,3,6-tetrahydropyridine 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.
