Description | 6-Hydroxykaempferol, a competitive tyrosinase inhibitor (IC50=124 nM), belongs to the flavonoids class and is a natural product derived from Carthamus tinctorius. Compared with L-DOPA, 6-Hydroxykaempferol can bind to the active site of tyrosinase with higher activity and also has high antioxidant activity. |
In vitro | Baicalein (1), 6-Hydroxyapigenin (6), 6-hydroxygalangin (13) and 6-hydroxy-kaempferol (14), which are naturally occurring flavonoids from a set of 14 hydroxy-flavones tested, exhibited high inhibitory effects on tyrosinase with respect to L-DOPA, while each of the 5,6,7-trihydroxyflavones 1, 6, 13 or 14 acted as a cofactor to monophenolase. Moreover, 6-Hydroxykaempferol (14) showed the highest activity and was a competitive inhibitor of tyrosinase compared to L-DOPA. 5,6,7-Trihydroxyflavones 1, 6, 13 or 14 showed also high antioxidant activities. |
