Metabolite Identification
Common NameDifenoxin
DescriptionDifenoxin, also known as diphenoxilic acid or diphenoxilate, belongs to the class of organic compounds known as diphenylacetonitriles. These are cyclic aromatic compounds containing a diphenylacetonitrile moiety, which consists of a diphenylmethane linked to and acetonitrile to form 2,2-diphenylacetonitrile. Based on a literature review very few articles have been published on Difenoxin. This compound has been identified in human blood as reported by (PMID: 31557052 ). Difenoxin is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Difenoxin 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.
