Metabolite Identification
Common Name7-Methoxy-3H-phenoxazin-3-one
Description7-Methoxy-3H-phenoxazin-3-one, also known as 7-methoxyresorufin or methyl resorufin ether, 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 7-Methoxy-3H-phenoxazin-3-one. This compound has been identified in human blood as reported by (PMID: 31557052 ). 7-methoxy-3h-phenoxazin-3-one is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically 7-Methoxy-3H-phenoxazin-3-one 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.
