Dihydromethysticin is one of the six major kavalactones found in the kava plant.^[1]

Pharmacology

Dihydromethysticin has marked activity on the induction of CYP3A23, as does the related chemical desmethoxyyangonin.^[2]

Both dihydromethysticin and methysticin induce the hepatic enzyme CYP1A1, which increases the amount of the very highly carcinogenic benzo[a]pyrene-7,8-dihydrodiol-9,10-epoxide in the body (via the metabolism of benzo[a]pyrene) and may be responsible for some of the toxic effects associated with kava consumption.

Metabolism of benzo[a]pyrene yielding the carcinogenic benzo[a]pyren-7,8-dihydrodiol-9,10-epoxide.

In vitro, dihydromethysticin possesses analgesic, anticonvulsant, and anxiolytic effects.^[3] It has been found to act as a GABA_A receptor positive allosteric modulator and as an reversible inhibitor of monoamine oxidase B.^[4][5]
