Abstract

In the course of our screening of NF-κB inhibitors, we isolated known flavonoids that inhibit LPS-induced NO production in mouse monocytic leukemia RAW264.7 cells. Since those flavonoids inhibited the NF-κB activity, we have evaluated the inhibitory activity of plant-derived novel flavonoid, desmal, on NF-κB, and found that it inhibits LPS-induced NO production and NF-κB. It also inhibited cellular invasion possibly by the decrease of NF-κB-dependent urokinase-type plasminogen activator. Thus, desmal was found to be a new NF-κB inhibitor having cellular anti-inflammatory and anti-metastatic activities.
