Metabolite Identification
Common NameMikamycin B
DescriptionPristinamycin IA, also known as vernamycin b alpha or mikamycin b, belongs to the class of organic compounds known as flavonoid-7-o-glycosides. These are phenolic compounds containing a flavonoid moiety which is O-glycosidically linked to carbohydrate moiety at the C7-position. Pristinamycin IA is a strong basic compound (based on its pKa). This compound has been identified in human blood as reported by (PMID: 31557052 ). Mikamycin b is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Mikamycin B 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.
