Metabolite Identification
Common Name11-Dehydrodexamethasone
Description1-fluoro-14,17-dihydroxy-14-(2-hydroxyacetyl)-2,13,15-trimethyltetracyclo[8.7.0.0²,⁷.0¹¹,¹⁵]heptadeca-3,6,16-trien-5-one belongs to the class of organic compounds known as 21-hydroxysteroids. These are steroids carrying a hydroxyl group at the 21-position of the steroid backbone. Based on a literature review a significant number of articles have been published on 1-fluoro-14,17-dihydroxy-14-(2-hydroxyacetyl)-2,13,15-trimethyltetracyclo[8.7.0.0²,⁷.0¹¹,¹⁵]heptadeca-3,6,16-trien-5-one. This compound has been identified in human blood as reported by (PMID: 31557052 ). 11-dehydrodexamethasone is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically 11-Dehydrodexamethasone 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.
