A flavonoid with diverse biological activities; reduces viral titers of H5N1 influenza isolates by 79.66% in a plaque assay at 1 ng/ml; inhibits apoptosis, increases cell viability, and decreases the level of ROS in an oxygen-glucose deprivation/reoxygenation assay in primary rat hippocampal neurons at 25, 50, and 100 μg/ml; decreases TNF-α-induced cell death in primary mouse hepatocytes (IC50 = 37.5 μM); reduces infarct volume and neurological symptoms in a rat model of MCAO at 50 mg/kg
