Metabolite Identification
Common NameSplitomicin
DescriptionSplitomicin belongs to the class of organic compounds known as naphthopyranones. Naphthopyranones are compounds containing a naphthopyran skeleton where a ring carbon bears a carboxylic acid group. Naphthtopyran is made up of the pyran ring fused to a naphthalene ring system. Based on a literature review a significant number of articles have been published on Splitomicin. This compound has been identified in human blood as reported by (PMID: 31557052 ). Splitomicin is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Splitomicin 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.
