Inhibition of melanogenesis by 5,7-dihydroxyflavone (chrysin) via blocking adenylyl cyclase activity.

Due to its multiple biological activities, 5,7-dihydroxyflavone (chrysin) in propolis has gained attention as potentially useful therapeutics for various diseases. However, the efficacy of chrysin for the use of dermatological health has not been fully explored. To clarify the action mechanism of the skin protecting property of chrysin, we firstly investigated the molecular docking property of chrysin on the mammalian adenylyl cyclase, which is the key enzyme of cAMP-induced melanogenesis.
