Dehydroleucodine is a bioactive sesquiterpene lactone. Herein, four dehydroleucodine amino derivatives were synthesized using the amines proline, piperidine, morpholine, and tyramine, and spectroscopic methods and single-crystal X-ray diffraction unambiguously established their structures. The cytotoxic activity of these compounds was evaluated against eight acute myeloid leukemia cell lines, and their
The biomimetic synthesis of guaianolide dimers lavandiolides H, I, and K and artematrolide F containing a spirolactone moiety has been accomplished for the first time from naturally abundant arglabin in four to six steps with an overall yield up to 60%, and a series of natural product-like guaianolide dimers, trimer, and tetramer were also successfully synthesized. Notably, the trimeric compound exhibited

The present invention provides dehydroleucodine derivatives. In particular, the present invention provides amine derivatives of dehydroleucodine and methods of using dehydroleucodine and the amine derivatives of dehydroleucodine to inhibit the growth of cancer cells.
The invention provides the use of enzymes derived from plants in biocatalysis. The regio- and stercoselective introduction of an oxygen group into an unactivated organic compound is still a largely unresolved challenge to organic chemistry (Faber, 2000). We have shown that enzymes of Asteraceae species are capable of converting with high regio- and stereospecificity for example sesquiterpene olefins to commercially interesting products.
