Many sesquiterpene lactone compounds either induce or enhance the cell differentiation of human leukemia cells. However, we reported in a previous study that santonin, a eudesmanolide sesquiterpene lactone, exerts no effects on the differentiation of leukemia cells. In this report, to evaluate the

One new eudesmane sesquiterpenoid, 11β-hydroxy-13-chloro-eudesm-5-en-12, 8-olide (1), was isolated from the roots of Inula helenium together with nine eudesmanolides (2-10) and one germacranolide (11). Their structures were elucidated on the basis of detailed spectroscopic analyses. All isolates

The eudesmanolide tanapsin from Tanacetum oshanahanii and its acetate induce cell death in human tumor cells through a mechanism dependent on reactive oxygen species.
