Ivalin, an eudesmane-type sesquiterpene compound, was isolated from the Chinese herb Carpesium divaricatum in our chemistry group. In this study, we investigated the anti-migration and anti-invasion activities and underlying mechanisms of Ivalin in breast cancer cells in vitro. Cell viability was
Ivalin is a plant alkaloid that inhibits the induction of tumors in animals. Phomopsin is a mycotoxin known to be carcinogenic. To determine if these compounds influence endocrine responsiveness, their effect on steroid receptors was measured. Neither of these toxins had a direct effect on either
The influences of two toxins, phomopsin and ivalin, which are reported to exhibit carcinogenic and antitumor activities, respectively, were studied on steroid hormone receptor binding. A mycotoxic carcinogenic fraction A (phomopsin) was isolated from Phomopsis leptostromiformis. The antitumor
Background and Objectives: Microtubules are an attractive target for cancer chemotherapy. Previously, we reported that Ivalin exhibited excellent anti-migration and anti-invasion activities in human breast cancer cells. Here, we examined the microtubule inhibition effect of Ivalin in human
Eight sesquiterpene lactones, 4 alpha,5 alpha-epoxy-10 alpha,14-dihydro-inuviscolide (1), 2,3-dihydroaromomaticin (2), carpesiolin (3), carabrone (4), carabrol (5), telekin (6), ivalin (7) and 11,13-didehydroivaxillin (8), were isolated from the aerial parts of Carpesium abrotanoides Linne
Three new sesquiterpene lactone dimers (SLDs), carpedilactones E-G (1-3), together with two known monomeric units, ivalin (4) and alantolactone (5), were isolated from the acetonic extract of Carpesium macrocephalum. Their chemical structures were elucidated by IR, UV, HR-ESI-MS, NMR 1D and 2D
