Metabolite Identification

Common Name

Tempo-maleimide

Description

Tempo-maleimide, also known as MAL-6 or 4-maleimido-tempo, belongs to the class of organic compounds known as maleimides. Maleimides are compounds containing a 2,5-pyrroledione moiety. Based on a literature review a significant number of articles have been published on Tempo-maleimide. This compound has been identified in human blood as reported by (PMID: 31557052 ). Tempo-maleimide is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Tempo-maleimide 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.
