Dehydroleucodine is a sesquiterpene lactone isolated from Artemisia douglasiana Besser; mast cell stabilizers. An extract from the plant is widely used in Cuyo region (Argentina) as folk medicine for the treatment of gastric ailments. The compound prevents gastric and duodenal damages in response to necrosis-inducing agents. Stabilization of mast cells may be a key mechanism to protect the gastrointestinal tract from injury and ulceration. Recently, it was established that dehydroleucodine and xanthatin inhibit mast cell degranulation induced by compound 48/80.
The aim of the present study was to determine whether dehydroleucodine, xanthatin and 3-benzyloxymethyl-5H-furan-2-one inhibit the activation of human leukemic LAD2 mast cells induced by compound 48/80 or the calcium ionophore A23187. LAD2 cells were preincubated in the presence of
In amphibian oocytes meiosis, the transition from G2 to M phase is regulated by the maturation promoting factor (MPF), a complex of the cyclin-dependent kinase p34/cdc2 and cyclin B. In immature oocytes there is an inactive complex (pre-MPF), in which
Dehydroleucodine (DhL), a sesquiterpene lactone obtained from Artemisia douglasiana, was screened for antidiarrheal effects. DhL inhibited castor oil-induced diarrhea in mice by judged by a decrease in the number of wet faeces in the DhL-treatment groups. DhL significantly reduced intestinal
Sesquiterpene lactones (SLs) are plant-derived compounds that display anti-cancer effects. Some SLs derivatives have a marked killing effect on cancer cells and have therefore reached clinical trials. Little is known regarding the mechanism of action of SLs. We studied the
In this work, Dehydroleucodine (DhL) was evaluated as a chemical activator of bovine oocytes and somatic cell nuclear transfer (SCNT) reconstituted embryos. Oocytes were activated with 5 microM Ionomycin (Io) and exposed for 3 h to 1 or 5 microM
