Metabolite Identification
Common Name7-O-Demethyl Rapamycin
Description7-O-Demethyl Rapamycin belongs to the class of organic compounds known as macrolide lactams. These are cyclic polyketides containing both a cyclic amide and a cyclic ester group. Based on a literature review a significant number of articles have been published on 7-O-Demethyl Rapamycin. This compound has been identified in human blood as reported by (PMID: 31557052 ). 7-o-demethyl rapamycin is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically 7-O-Demethyl Rapamycin 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.
