Metabolite Identification
Common NameQuinmerac
Descriptionquinmerac, also known as BAS 518, 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 a small amount of articles have been published on quinmerac. This compound has been identified in human blood as reported by (PMID: 31557052 ). Quinmerac is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Quinmerac 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.
