Metabolite Identification
Common Nameisoquinoline-1-carboxamide
Descriptionisoquinoline-1-carboxamide belongs to the class of organic compounds known as isoquinolines and derivatives. These are aromatic polycyclic compounds containing an isoquinoline moiety, which consists of a benzene ring fused to a pyridine ring and forming benzo[c]pyridine. Based on a literature review very few articles have been published on isoquinoline-1-carboxamide. This compound has been identified in human blood as reported by (PMID: 31557052 ). Isoquinoline-1-carboxamide is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically isoquinoline-1-carboxamide 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.
