Common NameNomegestrol acetate
Description14-acetyl-8,15-dimethyl-5-oxotetracyclo[8.7.0.0²,⁷.0¹¹,¹⁵]heptadeca-6,8-dien-14-yl acetate belongs to the class of organic compounds known as gluco/mineralocorticoids, progestogins and derivatives. These are steroids with a structure based on a hydroxylated prostane moiety. Based on a literature review very few articles have been published on 14-acetyl-8,15-dimethyl-5-oxotetracyclo[8.7.0.0²,⁷.0¹¹,¹⁵]heptadeca-6,8-dien-14-yl acetate. This compound has been identified in human blood as reported by (PMID: 31557052 ). Nomegestrol acetate is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Nomegestrol acetate 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.
