tanacetum macrophyllum/glutathione

Morphological and biochemical responses of feverfew plants exposed to low (5 μM) and high (35 and 70 μM) levels of Cd or Cu were investigated. Increasing metal supply notably reduced the plant biomass. Elevated Cd and Cu levels also resulted in an increase in the leaf proline content. Besides,

BACKGROUND Few treatments are available that can safely and effectively stimulate new platelet production for thrombocytopenic patients. Additionally, recipients of transfused platelets may experience an inflammatory response due to stored platelets becoming unnecessarily activated, thus creating

Parthenolide (PT), a sesquiterpene lactone derived from the plant feverfew, has pro-apoptotic activity in a number of cancer cell types. We assessed whether PT induces the apoptosis of hepatic stellate cells (HCSs) and examined its effects on hepatic fibrosis in an in vivo model. The effects of PT

Milk from lactating goats fed tansy ragwort (Senecio jacobaea) was evaluated for its ability to influence hepatic drug metabolism. The milk after being freeze-dried was fed to male rats for 1 week ad lib. A significant reduction in the activities of hepatic aminopyrine N-demethylase and aryl

Effect of dietary tancy ragwort (Senecio jacobaea), comfrey (Symphytum officinale), bracken (Pteridium aquilinum) and alfalfa (Medicago sativa) on hepatic drug-metabolizing enzymes in rats were measured. Tansy ragwort and bracken increased (P less than 0.05) the activity of glutathione transferase

It has been suggested that extracts of feverfew may inhibit platelet behaviour via effects on platelet sulphydryl groups. In the present study we have obtained evidence for such a mode of action. Compounds that contain sulphydryl groups such as cysteine and N-(2-mercaptopropionyl)glycine prevented

Parthenolide is a natural product from the shoots of Tanacetum parthenium that has been demonstrated to have immunomodulatory effects in a number of diseases. The present study aimed to determine the effect and mechanism of parthenolide on the apoptotic ability of H2O2‑induced osteoblasts. Cell

Parthenolide, the main bioactive compound of the medicinal plant feverfew (Tanacetum parthenium), is a promising anti-cancer drug. However, the biosynthetic pathway of parthenolide has not been elucidated yet. Here we report on the isolation and characterization of all the genes from feverfew that

The sesquiterpene costunolide has a broad range of biological activities and is the parent compound for many other biologically active sesquiterpenes such as parthenolide. Two enzymes of the pathway leading to costunolide have been previously characterized: germacrene A synthase (GAS) and germacrene

Parthenolide is one of the main components responsible for the anti-inflammatory property of Feverfew. Recently, parthenolide has shown to induce apoptosis in cancer cells. Here we further studied the mechanism of parthenolide-induced apoptosis by focusing on the role of intracellular thiols and
