Ochnaflavone is an inhibitor of IIA-type secretory phospholipase A2 (sPLA2-IIA) with an IC50 of 3.45 μM. Ochnaflavone exhibits significant anti-inflammatory and liver-protective effects, capable of inhibiting the degradation of phosphatidylethanolamine (PE) and lipid peroxidation induced by carbon tetrachloride (CCl4) in rat liver, with an IC50 of 7.16 μM for lipid peroxidation. Ochnaflavone can be used in research on liver damage and inflammatory diseases[1].

ChEBI: Ochnaflavone is a biflavonoid with an ether linkage between the B-rings of the apigenin and luteolin subunits. It has been isolated from several members of the Ochnaceae plant family. It has a role as a plant metabolite, an antibacterial agent, a leukotriene antagonist, an anti-inflammatory agent, an EC 3.1.1.4 (phospholipase A2) inhibitor and an antiatherogenic agent. It is a biflavonoid, an aromatic ether and a hydroxyflavone. It is functionally related to a luteolin and an apigenin.
