Ainsliatrimers A and B, the first two guaianolide trimers from Ainsliaea fulvioides

Org Lett. 2008 Dec 18;10(24):5517-20. doi: 10.1021/ol802249z.

Abstract

Ainsliatrimers A (1) and B (2), the first two guaianolide-type sesquiterpene lactone trimers, together with one new structurally related sesquiterpene dimer ainsliadimer B (3), were isolated from the aerial part of Ainsliaea fulvioides. Their structures were elucidated by spectroscopic techniques, including X-ray crystal diffraction. Both 1 and 2 showed potent cytotoxicites against LOVO and CEM cell lines.
