Metabolite Identification
Common NamePyrithione
Descriptionpyrithione belongs to the class of organic compounds known as dihydropyridines. Dihydropyridines are compounds containing a dihydropyridine moiety, which is a semi-saturated pyridine derivative with two double bonds. Based on a literature review very few articles have been published on pyrithione. This compound has been identified in human blood as reported by (PMID: 31557052 ). Pyrithione is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Pyrithione 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.
