Paragraph 0027; 0028; 0029; 0030, (2016/10/10)
The invention relates to a preparation method and applications of parthenolide analogues, and belongs to the field of organic synthesis. On the basis of reserving the main active group alpha-methylene-gamma-lactone and epoxide structure of parthenolide, series of compounds are designed by changing its framework, and its in-vitro antitumor activity is tested. Series of parthenolide analogues having biological activity are synthesized by a simple method, wherein two compounds are nontoxic to normal cells.
