title: Repandiol, a new cytotoxic diepoxide from the mushrooms Hydnum repandum and H. repandum var. album.
abstract: Repandiol, a new cytotoxic diepoxide has been isolated from the mushrooms Hydnum repandum and H. repandum var. album. The chemical structure was elucidated as (2R,3R,8R,9R)-4,6-decadiyne-2,3:8,9-diepoxy-1,10-diol on the basis of spectroscopic analysis. The structure was confirmed by the synthesis of optically active repandiol. Repandiol displayed potent cytotoxic activity against various tumor cells.
