Background:

Prunetin is an isoflavone that has been found in P. yedoensis and has diverse biological activities.1,2,3,4,5 It is an allosteric inhibitor of hamster liver aldehyde dehydrogenase 2 (ALDH2; IC50 = 0.45 μM) and an antagonist of the progesterone receptor when used at concentrations of 25 and 50 μM.2,3 It has estrogenic activity in MVLN cells when used at concentrations ranging from 1 to 50 μM and inhibits proliferation of MCF-7 breast cancer cells when used at 0.01 to 50 μM.4 It decreases LPS-induced increases in nitric oxide (NO) and prostaglandin E2 levels, NOS2/iNOS expression, and NF-κB activation in RAW 264.7 macrophages when used at concentrations of 50 and 100 μM.1 Prunetin (10 mg/kg) prevents LPS-induced increases in serum TNF-α, IL-1β, and IL-6 levels in a mouse model of septic shock. It also inhibits the secretion of matrix metalloproteinase-3 (MMP-3) in isolated rabbit articular chondrocytes and prevents the production of MMP-3 in the knee joint of rats in a model of osteoarthritis following administration of a 50 or 100 μM dose into the knee joint.5
