Metabolite Identification
Common Name1-Methyl-5-(4-benzoyl)pyrrole-2-acetic acid 2-(theophylline-7-yl)ethyl ester
Description1-Methyl-5-(4-benzoyl)pyrrole-2-acetic acid 2-(theophylline-7-yl)ethyl ester, also known as MED 27, belongs to the class of organic compounds known as aryl-phenylketones. These are aromatic compounds containing a ketone substituted by one aryl group, and a phenyl group. Based on a literature review very few articles have been published on 1-Methyl-5-(4-benzoyl)pyrrole-2-acetic acid 2-(theophylline-7-yl)ethyl ester. This compound has been identified in human blood as reported by (PMID: 31557052 ). 1-methyl-5-(4-benzoyl)pyrrole-2-acetic acid 2-(theophylline-7-yl)ethyl ester is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically 1-Methyl-5-(4-benzoyl)pyrrole-2-acetic acid 2-(theophylline-7-yl)ethyl ester 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.
