Metabolite Identification

Common Name

4-Hydroxyquinoline

Description

quinolin-4-ol, also known as 4-chinolinol or kynurine, belongs to the class of organic compounds known as hydroquinolones. Hydroquinolones are compounds containing a hydrogenated quinoline bearing a ketone group. Based on a literature review a significant number of articles have been published on quinolin-4-ol. This compound has been identified in human blood as reported by (PMID: 31557052 ). 4-hydroxyquinoline is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically 4-Hydroxyquinoline 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.
