Metabolite Identification
Common NameFenyramidol
DescriptionFenyramidol belongs to the class of organic compounds known as aminopyridines and derivatives. These are organic heterocyclic compounds containing an amino group attached to a pyridine ring. Fenyramidol (INN) or phenyramidol (BAN, USAN), trade name Cabral, is a pharmaceutical drug which acts as a muscle relaxant. Fenyramidol is a very strong basic compound (based on its pKa). This compound has been identified in human blood as reported by (PMID: 31557052 ). Fenyramidol is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Fenyramidol 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.
