6hydroxykaempferol

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.

6-Hydroxykaempferol 3-O-beta-D-glucoside has anti-thrombotic,and antioxidative activities.

6-Hydroxykaempferol 3,6-diglucoside is a natural product isolated from Carthamus tinctorius that inhibits collagen-induced platelet aggregation.

6-Hydroxykaempferol 3-Rutinoside-6-glucoside is a natural product found in Carthamus tinctorius with antioxidant activity.

6-Hydroxykaempferol 7-O-β-glucopyranoside (compound 5), a flavonol, has been isolated from the plant Tagetes minuta (wild marigold) [1].

6-Hydroxykaempferol 3,6,7-tri-O-glucoside and 6-hydroxykaempferol 3,6-di-O-glucoside can inhibit platelet aggregation induced by collagen, they also show weak inhibitory effects on the adenosine 5'-diphosphate (ADP)- induced platelet aggregation.
