Hodoodo CAT#: H406634
CAS#: 550-24-3
Description: 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.

Biological target: | Embelin (Embelic acid), a potent, nonpeptidic XIAP inhibitor (IC50=4.1 μM), inhibits cell growth, induces apoptosis, and activates caspase-9 in prostate cancer cells with high levels of XIAP. |
In vitro activity: | This study used an MTT assay to examine the cytotoxic impact of embelin within 0 to 100 μM concentration range for 24 and 48 h on three breast cancer cell lines MDA-MB-231, MCF-7, and MDA-MB-453. The results of treatment for 24 and 48 h showed that three breast cancer cell lines exhibited dose-dependent cytotoxicity in 0 to 50 μM treatment of embelin.

In vivo activity: | Embelin (EMB) treatment increased the seizure threshold to hind limb extension (HLE) in the ICES test and decreased the seizure scores in the kindling experiment. Significantly low levels of IL-1β, IL-1Ra, IL-6, and TNF-α were observed in the hippocampus of PTZ + EMB (10 and 20 mg/kg)-treated mouse groups compared with PTZ+ vehicle-treated group.
