Metabolite Identification
Common NameN-(Tetrahydro-2-oxo-3-thienyl)-3-pyridinecarboxamide
DescriptionN-(Tetrahydro-2-oxo-3-thienyl)-3-pyridinecarboxamide, also known as ST 22 or homocysteine-thiolactone-nicotinamide, belongs to the class of organic compounds known as n-acyl-alpha amino acids and derivatives. N-acyl-alpha amino acids and derivatives are compounds containing an alpha amino acid (or a derivative thereof) which bears an acyl group at its terminal nitrogen atom. Based on a literature review a significant number of articles have been published on N-(Tetrahydro-2-oxo-3-thienyl)-3-pyridinecarboxamide. This compound has been identified in human blood as reported by (PMID: 31557052 ). N-(tetrahydro-2-oxo-3-thienyl)-3-pyridinecarboxamide is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically N-(Tetrahydro-2-oxo-3-thienyl)-3-pyridinecarboxamide 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.
