Common Name | N-Demethyl Mifepristone |
---|
Description | N-Demethyl Mifepristone belongs to the class of organic compounds known as oxosteroids. These are steroid derivatives carrying a C=O group attached to steroid skeleton. Based on a literature review a significant number of articles have been published on N-Demethyl Mifepristone. This compound has been identified in human blood as reported by (PMID: 31557052 ). N-demethyl mifepristone is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically N-Demethyl Mifepristone 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. |
