Metabolite Identification
Common NameHonokiol
DescriptionHonokiol belongs to the class of organic compounds known as biphenyls and derivatives. These are organic compounds containing to benzene rings linked together by a C-C bond. Honokiol is an extremely weak basic (essentially neutral) compound (based on its pKa). Honokiol induces caspase-dependent apoptosis in a TRAIL-mediated manner, and potentiates the pro-apoptotic effects of doxorubicin and other etoposides. This compound has been identified in human blood as reported by (PMID: 31557052 ). Honokiol is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Honokiol 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.
