一种具有抗病毒和抗炎作用的生物类黄酮。Amentoflavone is a bioflavonoid that has anti-viral and anti-inflammatory properties. The compound has been observed to inhibit the expression of INOS, LPS-induced activation of NFκB p50 (NF-κ B), translocation of p65 by LPS and block IKKα(I-κ B α) degradation in macrophages. Amentoflavone has been shown to up-regulate PPAR-γ and block the induction of COX-2. It is a negative modulator of the GABAA receptor at the benzodiazepine binding site. The compound has demonstrated anti-viral activity against respiratory syncytial virus (RSV), with an IC50 of 5.5 μg/ml. Amentoflavone has also pronounced inhibition at an IC50 = 14.9 +/- 1.9 nM of benzodiazepine binding in vitro.
