Metabolite Identification
Common Name(16R,17R)-3-Cyclopentyloxy-17-ethynyl-13-methyl-7,8,9,11,12,14,15,16-octahydro-6H-cyclopenta[a]phenanthrene-16,17-diol
Description5-(cyclopentyloxy)-14-ethynyl-15-methyltetracyclo[8.7.0.0²,⁷.0¹¹,¹⁵]heptadeca-2,4,6-triene-13,14-diol belongs to the class of organic compounds known as estrane steroids. These are steroids with a structure based on the estrane skeleton. Based on a literature review very few articles have been published on 5-(cyclopentyloxy)-14-ethynyl-15-methyltetracyclo[8.7.0.0²,⁷.0¹¹,¹⁵]heptadeca-2,4,6-triene-13,14-diol. This compound has been identified in human blood as reported by (PMID: 31557052 ). (16r,17r)-3-cyclopentyloxy-17-ethynyl-13-methyl-7,8,9,11,12,14,15,16-octahydro-6h-cyclopenta[a]phenanthrene-16,17-diol is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically (16R,17R)-3-Cyclopentyloxy-17-ethynyl-13-methyl-7,8,9,11,12,14,15,16-octahydro-6H-cyclopenta[a]phenanthrene-16,17-diol 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.
