Metabolite Identification

Common Name

Pinacidil pyridine N-oxide

Description

Pinacidil pyridine N-oxide, also known as pinacidil N-oxide, 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 a significant number of articles have been published on Pinacidil pyridine N-oxide. This compound has been identified in human blood as reported by (PMID: 31557052 ). Pinacidil pyridine n-oxide is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Pinacidil pyridine N-oxide 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.
