Metabolite Identification

Common Name

3-Isobutyl-1-methylxanthine

Description

3-Isobutyl-1-methylxanthine, also known as 1-methyl-3-isobutylxanthine or IBMX, belongs to the class of organic compounds known as xanthines. These are purine derivatives with a ketone group conjugated at carbons 2 and 6 of the purine moiety. Based on a literature review a significant number of articles have been published on 3-Isobutyl-1-methylxanthine. This compound has been identified in human blood as reported by (PMID: 31557052 ). 3-isobutyl-1-methylxanthine is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically 3-Isobutyl-1-methylxanthine 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.
