Metabolite Identification
Common Name2,4-Quinolinediol
Description2,4-Quinolinediol, also known as 4-hydroxycarbostyril or DHQ quinolinol, belongs to the class of organic compounds known as hydroxyquinolones. Hydroxyquinolones are compounds containing a quinoline moiety bearing a hydroxyl group and a ketone. Quinoline or benzo[b]pyridine is a bicyclic compound that consists of benzene fused to a pyridine. 2,4-Quinolinediol is a primary metabolite. Primary metabolites are metabolically or physiologically essential metabolites. They are directly involved in an organism’s growth, development or reproduction. Based on a literature review a significant number of articles have been published on 2,4-Quinolinediol. This compound has been identified in human blood as reported by (PMID: 31557052 ). 2,4-quinolinediol is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically 2,4-Quinolinediol 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.
