Metabolite Identification
Common NameRepSox
Description2-[3-(6-methylpyridin-2-yl)-1H-pyrazol-4-yl]-1,5-naphthyridine belongs to the class of organic compounds known as pyrazolylpyridines. Pyrazolylpyridines are compounds containing a pyrazolylpyridine skeleton, which consists of a pyrazole linked (not fused) to a pyridine by a bond. Based on a literature review very few articles have been published on 2-[3-(6-methylpyridin-2-yl)-1H-pyrazol-4-yl]-1,5-naphthyridine. This compound has been identified in human blood as reported by (PMID: 31557052 ). Repsox is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically RepSox 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.
