Metabolite Identification
Common NameGardiquimod
DescriptionGardiquimod belongs to the class of organic compounds known as imidazoquinolines. These are aromatic heterocyclic compounds containing an imidazole ring fused to a quinoline ring system. In some configurations, the imidazole ring shares a nitrogen atom with the quinoline moiety. Based on a literature review a significant number of articles have been published on Gardiquimod. This compound has been identified in human blood as reported by (PMID: 31557052 ). Gardiquimod is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Gardiquimod 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.
