title: Antitumor agents, 115. Seselidiol, a new cytotoxic polyacetylene from Seseli mairei.
abstract: Seselidiol [1], a new polyacetylene, has been isolated from the roots of Seseli mairei. On the basis of chemical and spectroscopic evidence, its structure has been established as heptadeca-1,8(Z)-diene-4,6-diyne-3,10-diol. Seselidiol and its acetate have been demonstrated to show moderate cytotoxicity against KB, P-388, and L-1210 tumor cells.
