EXPERT OPINION

Embelin is the only known non-peptide small-molecule X-linked inhibitor of the apoptosis protein (XIAP) - an anti-apoptotic protein considered a promising cancer therapeutic target. Embelin acts as an NF-κB blocker and potential suppressor of tumorigenesis. It also exhibits potent cytotoxic, antioxidant and cancer chemopreventive effects. Given the potential uses of embelin, it is recommended that further investigations take place to properly explore its pharmacological and clinical effects.
