Biochem/physiol Actions EF-24 is a IKK inhibitor and curcumin analog. EF-24 is more potent and bioavailable than curcumin, with 10-fold greater potency in cell death induction. It is also more efficacious in anti-cancer screens and less toxic than Cisplatin. EF-24 inhibits HIF-1alpha posttranscriptional activity and induces microtubule stabilization, in contrast to Curcumin. EF-24 up-regulates PTEN expression via inhibition of ubiquitination. EF-24 induces cell death through direct inhibition of IkappaB kinase (IKK), resulting in suppression in NFκB activity. |
