Introduction | 6-hydroxyflavone is a flavonoid that is a non-competitive inhibitor of the cytochrome P450 enzyme CYP2C9. 6-hydroxyflavone can be found in the leaves of Rhododendron Aurea (scientific name: Barleria prionitis) and may be a potential drug for the treatment of Anxiety-like disorders. |
biological activity | 6-Hydroxyflavone is a naturally occurring flavonoid compound with anti-inflammatory properties. 6-Hydroxyflavone has an inhibitory effect on the glycosylation of bovine hemoglobin (BHb). 6-Hydroxyflavone can activate AKT, ERK 1/2, JNK signaling pathway, and effectively promote osteoblast differentiation. 6-Hydroxyflavone inhibits LPS-induced NO production. |
