Metabolite Identification
Common Name(5alpha)-23-Methyl-4-aza-21-norchol-1-ene-3,20-dione
Description1-{5-hydroxy-2,15-dimethyl-6-azatetracyclo[8.7.0.0²,⁷.0¹¹,¹⁵]heptadeca-3,5-dien-14-yl}-3-methylbutan-1-one belongs to the class of organic compounds known as 20-oxosteroids. These are steroid derivatives carrying a C=O group at the 20-position of the steroid skeleton. Based on a literature review very few articles have been published on 1-{5-hydroxy-2,15-dimethyl-6-azatetracyclo[8.7.0.0²,⁷.0¹¹,¹⁵]heptadeca-3,5-dien-14-yl}-3-methylbutan-1-one. This compound has been identified in human blood as reported by (PMID: 31557052 ). (5alpha)-23-methyl-4-aza-21-norchol-1-ene-3,20-dione is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically (5alpha)-23-Methyl-4-aza-21-norchol-1-ene-3,20-dione 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.
