Metabolite Identification
Common NameDolastatin 15
DescriptionNSC617668 belongs to the class of organic compounds known as depsipeptides. These are natural or synthetic compounds having sequences of amino and hydroxy carboxylic acid residues (usually α-amino and α-hydroxy acids), commonly but not necessarily regularly alternating. NSC617668 is a very strong basic compound (based on its pKa). This compound has been identified in human blood as reported by (PMID: 31557052 ). Dolastatin 15 is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Dolastatin 15 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.
