Metabolite Identification
Common NameThieno[3,2-b]pyridine
Descriptionthieno[3,2-b]pyridine belongs to the class of organic compounds known as thienopyridines. These are heterocyclic compounds containing a thiophene ring fused to a pyridine ring. Thiophene is 5-membered ring consisting of four carbon atoms and one sulfur atom. Pyridine is a 6-membered ring consisting of five carbon atoms and one nitrogen center. Based on a literature review very few articles have been published on thieno[3,2-b]pyridine. This compound has been identified in human blood as reported by (PMID: 31557052 ). Thieno[3,2-b]pyridine is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Thieno[3,2-b]pyridine 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.
