RESUMO
Nine new eudesmanolides (1-9), two new guaianolides (12 and 13), and a new germacrane (10), along with a previously reported guaianolide (11), have been isolated from the roots of Thapsia nitida var. meridionalis. Thapsia nitida var. nitida also afforded compound 13 along with a new guaianolide (14). The structure of 13 was confirmed by X-ray crystallographic analysis. Compounds 1, 2, and 11-14 have been tested as potential inhibitors of the sarco- and endoplasmic Ca2+-dependent ATPases (SERCA) pump. None of them showed significant activities.
