Isohelenin (470-17-7) is a sesquiterpene lactone isolated from Mexican Indian medicinal plants known to have anti-inflammatory properties. A potent inhibitor of NFkB (complete inhibition at 5 μM)1 acting via inhibition of IKK?6. Isohelenin-mediated NFkB inhibition suppresses IL-8 expression2, iNOS expression3 and RANTES biosynthesis4. Displays protective effects in endotoxic shock in rodent models.5 Induces apoptosis in glioma cells.6 | [Uses]
Isoalantolactone is a sesquiterpene lactone used in the treatment of cancer. It can inhibit tumor cell growth and induce apoptosis. | [Definition]
ChEBI: A sesquiterpene lactone of the eudesmanolide group. It has been isolated from Inula helenium. | [References]
