Biological Activity:
The active principle of feverfew (Chrysanthemum parthenium), widely used as a herbal remedy for arthritis and migraine and as a febrifuge. Antisecretory, anti-inflammatory and spasmolytic; inhibits the release of 5-HT from blood platelets. Also inhibits generation of leukotriene B4 and thromboxane B2.
Parthenolide is a sesquiterpene lactone from the plant feverfew (T. parthenium). It inhibits the growth of the promastigote form of L. amazonensis (IC50 = 3.6 μg/ml). Parthenolide also induces apoptosis in cancer cells, at least in part by inhibiting NF-κB- and STAT-mediated anti-apoptotic gene tranion. This compound has also been shown to block inflammation by inhibiting signaling through NF-κB. Inhibition of NF-κB by parthenolide can be achieved by direct binding of the pattern recognition receptor NOD2 by parthenolide.
