Beschreibung
Amentoflavone is a biflavonoid originally isolated from
Selaginella. It has a wide variety of biological effects including antibacterial, antioxidant, antiviral, antidiabetic, and neuroprotective activities. Amentoflavone has antiviral activity against the influenza A subtypes H1N1 and H3N2, influenza B, and herpes simplex virus 1 (EC
50s = 3.1 and 4.3, 0.56, and 17.9 μg/ml, respectively). It has antidiabetic effects such that it dose-dependently increases insulin receptor phosphorylation and activation and inhibits hydrolysis of
p-nitrophenyl phosphate (
p-NPP) catalyzed by protein tyrosine phosphatase 1B (PTP1B; IC
50 = 7.3 μM). Amentoflavone reduces the time mice spend immobile in the forced swim test, a measure of antidepressant efficacy, in a dose-dependent manner.
Biochem/physiol Actions
Biflavonoid with anti-inflammatory, anti-viral and cancer chemopreventive activity. It inhibits vascularization of tumors by blocking the activity of angiogenic VEGFs. Blocks the induction of COX-2 and up-regulates PPAR-γ. It is a negative modulator of the GABAA receptor at the benzodiazepine binding site.
