摘要
Four new eremophilane-type sesquiterpenes, culcitiolides A-D, were isolated from the stem of Senecio culcitioides Sch. Bip (Asteraceae). Their structures were established by detailed 2D NMR spectroscopic and single-crystal X-ray experiments. These compounds were assessed for inhibitory activity against nuclear factor kappa B (NF-kappa B). Culcitiolides C and D at 20 mu M showed 97 and 100% inhibition of NF-kappa B activity, respectively.
