Metabolite Identification
Common NameDiamfenetide
DescriptionDiamfenetide, also known as acemidophen or coriban, belongs to the class of organic compounds known as acetanilides. These are organic compounds containing an acetamide group conjugated to a phenyl group. Diamfenetide is a moderately basic compound (based on its pKa). This compound has been identified in human blood as reported by (PMID: 31557052 ). Diamfenetide is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Diamfenetide 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.
