Structure-Activity Investigations of stilbenes and related 4-substituted resorcinols, obtained from Artocarpus incisus and other plants suggested that the 4-substituted resorcinol skeleton have potent tyrosinase inhibitory ability [24]. Oxyresveratrol, a stilbene isolated from Morus alba, exhibited 32 times inhibitory effect of kojic acid on tyrosinase and the inhibitors act non-competitively on the enzyme [25]. In the structure analysis of extracts from licorice root, glabridin exerts the strongest inhibitory effect on tyrosinase and the inhibitory effect was more effective against monophenol oxidase activity, the rate-determining step, than diphenol oxidase activity [26]. However, glabridin's analog, glabrene, was 100-fold less active than glabridine while glyasperin C, isolated from the same part of the plant, was two times more active than glabridin [26, 27]. 6-hydroxydaidzein (6,7,4'-trihydroxyisoflavone), one kind of hydroxyisoflavones isolated from soybean koji fermented with Aspergillus oryzae, had 6-fold more than kojic acid acting competitively on the tyrosine binding site of the enzyme [28]. It is found that an isoflavone with hydroxyl groups at both the C6 and C7 positions in the A ring would increase both inhibitory effect and affinity to the enzyme more than 10 times [28].
