Actions biochimiques/physiologiques

Oroxylin A is a flavonoid isolated from Scutellaria baicalensis, which is one of the most important medicinal herbs in traditional Korean/Chinese/Japanese medicine. The amelioration of Abeta(25-35) peptide-induced memory impairment by oroxylin A is believed to be mediated via the GABAergic neurotransmitter system after a single administration, or by reductions in Abeta(25-35) peptide-induced astrocyte and microglia activations, iNOS expression, lipid peroxidation, and increased cholinergic neurotransmission after subchronic administration.

Radix Scutellariae is a commonly used herbal medicine. Baicalein, wogonin, and oroxylin A are three major bioactive flavones in Radix Scutellariae and share similar chemical structures. The intestinal absorption and disposition of baicalein have been systematically investigated by our group

Oroxylin A, a natural flavonoid, is one of the main bioactive compounds that underlie the anti-inflammatory effect of the medicinal herb Scutellaria baicalensis Georgi widely used in southeastern Asia; however, the molecular mechanisms for the therapeutic benefits remain largely unclear.

Based on the previous research that oroxylin A can suppress inflammation, we investigated the hepatoprotective role of oroxylin A against CCl₄-induced liver damage in mice and then studied the possible alteration of the activities of cytokine signaling participating in liver

PloS one, 7(10), e47403-e47403 (2012-10-17)
Successful drug treatment for sepsis-related acute lung injury (ALI) remains a major clinical problem. This study was designed to assess the beneficial effects of post-treatment of oroxylin A (OroA), a flavonoid, in ameliorating lipopolysaccharides (LPS)-induced lung inflammation and fatality. Rats
