| Common Name | (2S,3R)-2-Acetamido-3-hydroxy-4-methylpentanoate |
|---|
| Description | N-[1-(1-{18-benzyl-8,14-dihydroxy-21-[(1-hydroxyethylidene)amino]-3-(1-methoxyethyl)-4,9,10,12,16,22-hexamethyl-15-methylidene-2,5,11,17,20-pentaoxo-1,19-dioxa-4,7,10,13,16-pentaazacyclodocosa-7,13-dien-6-yl}-2-methylpropoxy)-3-hydroxy-4-methyl-1-oxopentan-2-yl]ethanimidic acid belongs to the class of organic compounds known as cyclic depsipeptides. These are natural or synthetic compounds having sequences of amino and hydroxy carboxylic acid residues (usually α-amino and α-hydroxy acids) connected in a ring. The residues are commonly but not necessarily regularly alternating. Based on a literature review very few articles have been published on N-[1-(1-{18-benzyl-8,14-dihydroxy-21-[(1-hydroxyethylidene)amino]-3-(1-methoxyethyl)-4,9,10,12,16,22-hexamethyl-15-methylidene-2,5,11,17,20-pentaoxo-1,19-dioxa-4,7,10,13,16-pentaazacyclodocosa-7,13-dien-6-yl}-2-methylpropoxy)-3-hydroxy-4-methyl-1-oxopentan-2-yl]ethanimidic acid. This compound has been identified in human blood as reported by (PMID: 31557052 ). (2s,3r)-2-acetamido-3-hydroxy-4-methylpentanoate is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically (2S,3R)-2-Acetamido-3-hydroxy-4-methylpentanoate 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. |
