| Hazard Information | Back Directory | [Uses]
Cirsiliol is a potent and selective 5-lipoxygenase inhibitor and a competitive low affinity benzodiazepine receptor ligand. | [Definition]
ChEBI: A dimethoxyflavone that is flavone substituted by methoxy groups at positions 6 and 7 and hydroxy groups at positions 5, 3' and 4' respectively. | [Biological Activity]
Cirsiliol is a flavonoid th at displays anti-inflammatoryanti-oxidantanti-proliferativeand anti-bacterial activities. Cirsiliol sensitizes non-small cell lung cancer cell lines (NSCLC) to radiation therapy. Cirsiliol inhibits epithelial-mesenchymal transition likely by induction of tumor-suppressive miR-34awhich suppresses Notch-1 expression NSCLC. | [in vivo]
In xenograft mouse model, tumor volume is significantly reduced by combinational treatment with irradiation and rhamnetin or cirsiliol compared with irradiation alone[2]. | [IC 50]
5-Lipoxygenase | [storage]
Store at -20°C | [References]
