A lactone isolated from the Kava plant (Piper methysticum). The active constituents of Kava are a group of approx. 18 compounds collectively referred to as kavalactones or kava pyrones. Kawain, dihydrokawain, methysticin, dihydromethysticin, yangonin, and desmethoxyyangonin are the six major kavalactones. Kava beverages and other preparations are known to be anxiolytic and are used for anxiety disorders. Dietary supplements containing the root of the kava shrub have been implicated in several cases of liver toxicity in humans, including several who required liver transplants after using kava supplements. |

| Hazard Information | Back Directory | [Description]
Yangonin is a natural kavalactone from the kava plant, P. methysticum. It enhances the binding of bicuculline at the γ-amino butyric acid (GABA) receptor GABAA at 1.0 μM.1 Yangonin also binds the central cannabinoid (CB1) receptor with a Ki value of 0.72 μM, but whether it serves as an agonist or antagonist at this receptor remains to be determined.2 Yangonin blocks the activation of NF-κB by TNF-α.3 It also inhibits anchorage-dependent and independent growth of bladder cancer cell lines through induction of autophagic cell death (IC50s = 15-59 mg/mL).4 | [Chemical Properties]
It is soluble in organic solvents such as methanol, ethanol, and DMSO. It is derived from the root of Piper methysticum Forst. | [Definition]
ChEBI: Yangonin is a member of 2-pyranones and an aromatic ether. | [IC 50]
