Stilbenoids of Kobresia nepalensis (Cyperaceae) exhibiting DNA topoisomerase II inhibition.
Yamada M, Hayashi K, Hayashi H, Ikeda S, Hoshino T, Tsutsui K, Tsutsui K, Iinuma M, and Nozaki H.
Resveratrol oligomers, nepalensinol A, B and C, were isolated from the stem of Kobresia nepalensis (Cyperaceae). The structures were established on the basis of chemical properties and spectroscopic evidence including 2D NMR spectroscopic analysis. Nepalensinol A, B and C showed a potent inhibitory effect on topoisomerase II - stronger than etoposide (VP-16), a topoisomerase II inhibitor used as an anti-cancer drug. Nepalensinol B, in particular, exhibited the most potent activity with an IC(50) of 0.02mug/ml.
