Metabolite Identification
Common NamePlumbagin
DescriptionPlumbagin, also known as 2-methyljuglone or plumbagone, belongs to the class of organic compounds known as naphthoquinones. Naphthoquinones are compounds containing a naphthohydroquinone moiety, which consists of a benzene ring linearly fused to a bezene-1,4-dione (quinone). Plumbagin has been detected, but not quantified in, several different foods, such as black walnuts (Juglans nigra), common walnuts (Juglans regia), japanese persimmons (Diospyros kaki), and persimmons (Diospyros). This could make plumbagin a potential biomarker for the consumption of these foods. Plumbagin is a secondary metabolite. Secondary metabolites are metabolically or physiologically non-essential metabolites that may serve a role as defense or signalling molecules. In some cases they are simply molecules that arise from the incomplete metabolism of other secondary metabolites. Based on a literature review a significant number of articles have been published on Plumbagin. This compound has been identified in human blood as reported by (PMID: 31557052 ). Plumbagin is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Plumbagin 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.
