Metabolite Identification
Common NamePhenoxazine
Description10H-phenoxazine, also known as phenazoxine, belongs to the class of organic compounds known as phenoxazines. These are polycyclic aromatic compounds containing a phenoxazine moiety, which is a linear tricyclic system that consists of a two benzene rings joined by a 1,4-oxazine ring. Based on a literature review a significant number of articles have been published on 10H-phenoxazine. This compound has been identified in human blood as reported by (PMID: 31557052 ). Phenoxazine is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Phenoxazine 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.
