Isolated from Lonchocarpus utilis and Lonchocarpus urucu, it acts as a NADH:ubiquinone reductase inhibitor. It has a role as an EC 1.6.5.3 [NADH:ubiquinone reductase (H(+)-translocating)] inhibitor and a plant metabolite. It is an extended flavonoid, a dimethoxyflavanone, a monohydroxyflavanone, a pyranochromane, a member of 4'-methoxyflavanones and a member of 3'-methoxyflavanones."}]
