Metabolite Identification
Common NameStrychnine N-oxide
DescriptionStrychnine N-oxide belongs to the class of organic compounds known as strychnos alkaloids. These are alkaloids having a core structure based on the strychnan, stemmadenine (seco-curan), or the akuammicine (curan) skeleton. Based on a literature review a significant number of articles have been published on Strychnine N-oxide. This compound has been identified in human blood as reported by (PMID: 31557052 ). Strychnine n-oxide is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Strychnine 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.
