Metabolite Identification
Common NameGamabufotalin
DescriptionGamabufagin belongs to the class of organic compounds known as bufanolides and derivatives. These are steroid lactones containing a pyran-2-one moiety linked to the C17 atom of a cyclopenta[a]phenanthrene derivative. Gamabufagin is an extremely weak basic (essentially neutral) compound (based on its pKa). This compound has been identified in human blood as reported by (PMID: 31557052 ). Gamabufotalin is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Gamabufotalin 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.
