Abstract
Mollugin a naphthoquinone derivative was reported to possess various biological activities such as antiinflammatory and antitumor activity Mollugin isolated from Rubia tinctorum roots inhibited lipopolysaccharideinduced nitric oxide NO production in RAW2647 macrophages However mollugin synthesized for further investigation of its antiinflammatory mechanism showed weak activity in addition to unstable assay results From the result of analysis on a degradation product of mollugin oxomollugin was found to be the main active substance of mollugin degradation showing a potent inhibitory activity on NOproduction including nuclear factor kappa B signals
