Metabolite Identification
Common Name9-cis Acitretin
Description9-cis Acitretin, also known as etretin or isoacitretin, belongs to the class of organic compounds known as retinoids. These are oxygenated derivatives of 3,7-dimethyl-1-(2,6,6-trimethylcyclohex-1-enyl)nona-1,3,5,7-tetraene and derivatives thereof. Based on a literature review very few articles have been published on 9-cis Acitretin. This compound has been identified in human blood as reported by (PMID: 31557052 ). 9-cis acitretin is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically 9-cis Acitretin 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.
