Abstract
Indole-3-carbaldehyde (1) was isolated as a tyrosinase inhibitor from the ethyl acetate-soluble fraction of extracellular fluids of unknown fungus YL185. The partial sequencing data of 18S ribosomal DNA (18S rDNA) indicate that this isolate belongs to the family Polyporaceae or Corticiaceae sensu lato. Indole-3-carbaldehyde inhibited the oxidation of l-3,4-dihydroxyphenylalanine (l-DOPA) by mushroom tyrosinase with a 50% inhibitory concentration (IC50) of 1.3 mM and showed inhibitory activity on melanin production in B16 melanoma cells. The aldehyde group of 1 plays an important role in eliciting tyrosinase inhibitory activity.
