Metabolite Identification

Common Name

Huperzine B

Description

Huperzine B, also known as fordimine, belongs to the class of organic compounds known as phenanthrolines. These are aromatic polycyclic compounds containing the phenanthroline skeleton, which is a derivative of phenanthrene, and consists of two pyridine rings non-linearly joined by a benzene ring. Based on a literature review very few articles have been published on Huperzine B. This compound has been identified in human blood as reported by (PMID: 31557052 ). Huperzine b is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Huperzine 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.
