Deguelin is a rotenone that is 13,13a-dihydro-3H-chromeno[3,4-b]pyrano[2,3-h]chromen-7(7aH)-one substituted by methoxy groups at positions 9 and 10, and by two methyl groups at position 3 (the 7aS,13aS-stereoisomer). It exists in abundant quantities in the bark, roots, and leaves of the Leguminosae family of plants and reported to exert anti-tumour effects in various cancers. It has a role as an antiviral agent, an antineoplastic agent, a mitochondrial NADH:ubiquinone reductase inhibitor, an angiogenesis inhibitor, an EC 2.7.11.1 (non-specific serine/threonine protein kinase) inhibitor, an anti-inflammatory agent, an apoptosis inducer and a plant metabolite. It is an aromatic ether, an organic heteropentacyclic compound, a diether and a member of rotenones.
説明Rotenoids, deriving from the flavonoid family of compounds, act as chemopreventive agents that inhibit NADH:ubiquinone oxidoreductase activity and suppress phorbol ester-induced ornithine decarboxylase (ODC) activity. The rotenoid compound deguelin, originally isolated from the bark of M. sericea (Leguminosae) to be used as an insecticide and fish poison, has chemopreventive and chemosensitizing effects in models of skin, mammary, colon, and lung carcinogenesis. Deguelin inhibits cell growth (IC50 = 8 M), blocks PI3K/Akt activation, suppresses COX-2 expression, and induces apoptosis in premalignant and squamous human bronchial epithelial (HBE) cells without affecting normal HBE cells. At 6 mg/kg, deguelin induces Parkinson’s disease-like symptoms in rats after six days of subcutaneous infusion and therefore may also serve as a useful model for Parkinson’s disease research.
使用Deguelin exhibits potent apoptotic and antiangiogenic activities in a variety of transformed cells and cancer cells. Deguelin also exhibits potent tumor suppressive effects in xenograft tumor models for many human cancers.
