Metabolite Identification
Common NameKynostatin 227
DescriptionN-tert-butyl-3-{2-hydroxy-3-[(1-hydroxy-2-{[1-hydroxy-2-(isoquinolin-5-yloxy)ethylidene]amino}-3-(methylsulfanyl)propylidene)amino]-4-phenylbutanoyl}-5,5-dimethyl-1,3-thiazolidine-4-carboximidic acid belongs to the class of organic compounds known as hybrid peptides. Hybrid peptides are compounds containing at least two different types of amino acids (alpha, beta, gamma, delta) linked to each other through a peptide bond. Based on a literature review very few articles have been published on N-tert-butyl-3-{2-hydroxy-3-[(1-hydroxy-2-{[1-hydroxy-2-(isoquinolin-5-yloxy)ethylidene]amino}-3-(methylsulfanyl)propylidene)amino]-4-phenylbutanoyl}-5,5-dimethyl-1,3-thiazolidine-4-carboximidic acid. This compound has been identified in human blood as reported by (PMID: 31557052 ). Kynostatin 227 is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Kynostatin 227 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.
