Aspochalasin I is a cytochalasan that disrupts actin dynamics and suppresses melanin production.
Details
Aspochalasin I is a cytochalasan-type secondary metabolite isolated from Aspergillus species. Its structure was established by spectroscopic analysis including NMR and mass spectrometry. Biologically, aspochalasin I inhibits melanogenesis in Mel-Ab melanocyte cells with an IC50 value of 22.4 µM without detectable cytotoxicity. Although cytochalasans are generally associated with actin cytoskeleton modulation, aspochalasin I has primarily been characterized for its melanin synthesis inhibitory activity.
