Beschreibung
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 (IC
50 = <10-
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.
Verwenden
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.
Biologische Aktivit?t
Anticancer and antiviral agent; chemopreventive and pro-apoptotic. Inhibits phorbol ester-induced ornithine decarboxylase and NADH:ubiquinone oxidoreductase activities (IC 50 values are 11 and 6.9 nM respectively). Inhibits PI 3-kinase and reduces pAkt levels in pre-malignant and malignant human bronchial epithelial cells. Active in vivo .
