定义
Diosmetin is a monomethoxyflavone that is the 4'-methyl ether derivative of luteolin. It is a natural product isolated from citrus fruits which exhibits a range of pharmacological activities. It has a role as a tropomyosin-related kinase B receptor agonist, an antioxidant, an antineoplastic agent, a vasodilator agent, an angiogenesis inhibitor, a bone density conservation agent, an anti-inflammatory agent, an apoptosis inducer, a plant metabolite and a cardioprotective agent. It is a monomethoxyflavone, a trihydroxyflavone and a 3'-hydroxyflavonoid. It is functionally related to a luteolin. It is a conjugate acid of a diosmetin-7-olate.
