Metabolite Identification
Common NamePiromidic acid
DescriptionPiromidic acid, also known as panacid or acide piromidique, belongs to the class of organic compounds known as pyrido[2,3-d]pyrimidines. Pyrido[2,3-d]pyrimidines are compounds containing the pyrido[2,3-d]pyrimidine ring system, which is a pyridopyrimidine isomer with three ring nitrogen atoms at the 1-, 3-, and 8- position. Based on a literature review a significant number of articles have been published on Piromidic acid. This compound has been identified in human blood as reported by (PMID: 31557052 ). Piromidic acid is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Piromidic acid 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.
