Description2-(1,3-dimethyl-2,6-dioxo-2,3,6,7-tetrahydro-1H-purin-7-yl)ethyl 2-(4-chlorophenoxy)-2-methylpropanoate, also known as etofylline clofibrate or duolip, 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 very few articles have been published on 2-(1,3-dimethyl-2,6-dioxo-2,3,6,7-tetrahydro-1H-purin-7-yl)ethyl 2-(4-chlorophenoxy)-2-methylpropanoate. This compound has been identified in human blood as reported by (PMID: 31557052 ). Etofylline clofibrate is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Etofylline clofibrate 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.
