The abnormal proliferation and migration of vascular smooth muscle cell (VSMC) contributes importantly to the pathogenesis of atherosclerosis and restenosis. Here, we investigated the effects of eupatolide (EuTL), a sesquiterpene lactone isolated from the medicinal plant Inula britannica, on
Tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) is a promising candidate for cancer therapeutics due to its ability to induce apoptosis selectively in cancer cells. However, sensitivity of cancer cells for induction of apoptosis by TRAIL varies considerably. Therefore, it is
Inula britannica is a traditional medicinal plant used to treat bronchitis, digestive disorders, and inflammation in Eastern Asia. Here, we identified eupatolide, a sesquiterpene lactone from I. britannica, as an inhibitor of cyclooxygenase-2 (COX-2) and inducible nitric oxide synthase (iNOS)
The epithelial-mesenchymal transition (EMT) is a hallmark of cancer metastasis, and the associated molecular signaling pathways are regarded as therapeutic targets for cancer treatment. Thus, suppressing EMT with a natural chemical compound may be of therapeutic benefit. Eupatolide is a natural
A new sesquiterpene, eupatolide 13-O-β-d-glucopyranoside (eupatolide-II, 1), lactone glucoside, along with 15 known compounds, were isolated from the whole plant of Inula salsoloides (Asteraceae). Dichloromethane extract and compounds 1-11 were used to investigate insecticidal activities against
Phytochemical investigation of the flowers of Inula japonica led to isolation of nine sesquiterpenoids, inujaponins A-I, as well as eighteen known ones. These sesquiterpenoids belong to six skeletal-types, including eudesmane, 1,10-seco-eudesmane, germacrane, guaiane, 4,5-seco-guaiane, and
A bioassay-guided isolation of an ethyl acetate-soluble extract of the aerial parts of Inula britannica var. chinensis (Rupr.) Regel, using an in vitro NF-kappaB reporter gene assay, led to the isolation of four new sesquiterpene dimers bearing a norbornene moiety, inulanolides A-D, and three known
