Metabolite Identification
Common Namebemegride
Descriptionbemegride, also known as megibal or methetharimide, belongs to the class of organic compounds known as piperidinediones. Piperidinediones are compounds containing a piperidine ring which bears two ketones. Based on a literature review very few articles have been published on bemegride. This compound has been identified in human blood as reported by (PMID: 31557052 ). Bemegride is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically bemegride 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.
