Identification of a Strigoterpenoid with Dual Nrf2 and Nf-κB Modulatory Activity

The sesquiterpene–coumarin ether samarcandone provided a suitable framework to replace the apocarotenoid A–C ring system of strigol (1), replicating, after linking to a butenolide moiety, the activity of the natural phytohormone on Nrf2 and also showing potent NF-kB inhibitory activity, overall modulating two critical pathways of inflammation and cancer
