3,7-DIMETHOXY-3',4',5-TRIHYDROXYFLAVONE Chemical Properties,Usage,Production

Uses

Di-O-methylated flavanol; a polyphenolic metabolite of Rhamnus disperma.

Definition

ChEBI: A dimethoxyflavone that is quercetin in which the hydroxy groups at the 3' and 7 positions have been replaced by methoxy groups.

in vivo

Rhamnazin (200 mg/kg; i.g.; daily for 25 days) inhibits breast cancer growth and angiogenesis in mice[1].
Rhamnazin (5-20 mg/kg; i.p.; once) shows strong antioxidant and anti-inflammatory properties in the rat acute lung injury model[2].

Animal Model:BALB/c nude mice, breast cancer xenograft model[1]
Dosage:200 mg/kg
Administration:Intragastric administration, daily for 25 days
Result:Dramatically suppressed tumor volumes by 47% compared with the vehicle group. Showed a significant reduction of pVEGFR2Tyr951-positive cells in tumors. Resulted in downregulation of VEGFR2 downstream molecules phosphorylation including MAPK, AKT and STAT3.

IC 50

VEGFR2: 4.68 μM (IC50)
