Aspochalasin I, a melanogenesis inhibitor from Aspergillus sp.
In the course of screening for the melanogenesis inhibitors, aspochalasin I was isolated from solid-state culture of Aspergillus sp. Fb020460. Its structure was determined by spectroscopic analysis including mass spectroscopy and NMR analysis. Aspochalasin I potently inhibited melanogenesis in Mel-Ab cells with an IC50 value of 22.4 microM without cytotoxicity.
