Metabolite Identification
Common Name5,7-Dichlorokynurenic acid
Description5,7-Dichlorokynurenic acid, also known as 5,7-dcka, belongs to the class of organic compounds known as quinoline carboxylic acids. These are quinolines in which the quinoline ring system is substituted by a carboxyl group at one or more positions. Based on a literature review very few articles have been published on 5,7-Dichlorokynurenic acid. This compound has been identified in human blood as reported by (PMID: 31557052 ). 5,7-dichlorokynurenic acid is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically 5,7-Dichlorokynurenic acid 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.
