Metabolite Identification
Common Name4H-Thieno[3,2-b]pyrrole-5-carboxylic acid
Description4H-Thieno[3,2-b]pyrrole-5-carboxylic acid belongs to the class of organic compounds known as thienopyrroles. These are heterocyclic compounds containing a thiophene ring fused to a pyrrole ring. Thiophene is 5-membered ring consisting of four carbon atoms and one sulfur atom. Pyrrole is 5-membered ring consisting of four carbon atoms and one nitrogen atom. Based on a literature review very few articles have been published on 4H-Thieno[3,2-b]pyrrole-5-carboxylic acid. This compound has been identified in human blood as reported by (PMID: 31557052 ). 4h-thieno[3,2-b]pyrrole-5-carboxylic acid is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically 4H-Thieno[3,2-b]pyrrole-5-carboxylic 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.
