Metabolite Identification
Common NameCarboxin
DescriptionCarboxin, also known as carbathiin or oxatin, belongs to the class of organic compounds known as anilides. These are organic heterocyclic compounds derived from oxoacids RkE(=O)l(OH)m (l not 0) by replacing an OH group by the NHPh group or derivative formed by ring substitution. Carboxin exists in all living organisms, ranging from bacteria to humans. Based on a literature review a small amount of articles have been published on Carboxin. This compound has been identified in human blood as reported by (PMID: 31557052 ). Carboxin is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Carboxin 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.
