Metabolite Identification
Common Name2'-Epi-Perindopril, (2'R)-
Description1-{2-[(1-ethoxy-1-oxopentan-2-yl)amino]propanoyl}-octahydro-1H-indole-2-carboxylic acid belongs to the class of organic compounds known as dipeptides. These are organic compounds containing a sequence of exactly two alpha-amino acids joined by a peptide bond. Based on a literature review very few articles have been published on 1-{2-[(1-ethoxy-1-oxopentan-2-yl)amino]propanoyl}-octahydro-1H-indole-2-carboxylic acid. This compound has been identified in human blood as reported by (PMID: 31557052 ). 2'-epi-perindopril, (2'r)- is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically 2'-Epi-Perindopril, (2'R)- 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.
