説明

The inhibitory activity of 40 stilbene oligomers isolated from six plant species against topoisomerase II was evaluated, of which nine compounds showed a potent inhibitory effect, stronger than daunorubicin, a topoisomerase II inhibitor, used as an anti-cancer drug. The specificity of active stilbene oligomers on topoisomerase II was assessed by their effect on DNA restriction enzyme. In particular, specific inhibitory activity was observed in α-viniferin 13-O-β-glucopryranoside (2) and hemsleyanol C (13).
