Extracts of Inula which contain tomentosin (33649-15-9) have been used for centuries in traditional medicine for the treatment of inflammation.1 It suppresses the production of inflammatory mediators in RAW264.7 cells by inhibiting NFkB activation.2 It induces telomere shortening and caspase-dependent apoptosis in cervical cancer cells3 and induces apoptosis in human osteosarcoma MG-63 cells4. It causes G2/M arrest and apoptosis in human melanoma cell lines.5

Tomentosin is a antiphlogistic sesquiterpene lactone that can be isolated from Inula falconeri.Tomentosin induces apoptosis and inhibits proliferation, migration and invasion of pancreatic cancer cells[1].

ChEBI: Tomentosin is a sesquiterpene lactone.
