4'hydroxyflavone

7,4'-Dimethoxy-3-hydroxyflavone is an orally active PAR4 antagonist. This compound inhibits PAR4-mediated human platelet aggregation with an IC50 of 1.4 μM. It disrupts PAR4-mediated aggregation and related signaling pathways, including NF-κB, Ca2+/protein kinase C (PKC), Akt, ERK, and p38. In a streptozotocin (STZ)-induced diabetic mouse model, 7,4'-Dimethoxy-3-hydroxyflavone inhibits vascular PAR4 expression, improves endothelial dysfunction, and reduces oxidative stress. Additionally, it prevents thrombosis in mice without affecting bleeding time.

7,4'-Di-O-methylapigenin (4',7-DIMETHOXY-5-HYDROXYFLAVONE) can inhibit α-glucosidase and α-amylase enzymes and enhance 2-NBDG uptake in L6 cells, it has hypolipidemic effect on mouse pre-adipocyte (3T3L1) cell lines.

4'-Hydroxyflavone is a flavonoid compound isolated from the roots of Scutellaria baicalensis with anti-inflammatory activity.
