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.

Irilone is a flavonoid with α-amylase inhibitory activity and highly selective inhibition of CYP3A4. In addition, Irilone enhances progesterone receptor (PR) signaling via estrogen receptor (ER) and glucocorticoid receptor (GR) when combined with progesterone.Irilone has potential anti-inflammatory activity and inhibits nitric oxide (NO) production by lipopolysaccharide (LPS)-induced RAW264.7 in mouse macrophages.
