Curcubitacin E is a potent actin depolymerization inhibitor. Shown to have a different mechanism of action compared to Jasplakinolide (Cat. No. 1689), binding to a different site. Binds specifically to filamentous actin (F-actin) forming a covalent bond at residue Cys257, stabilizing F-actin without affecting actin polymerization or nucleation. Does not bind to monomeric actin (G-actin). Acts as an immunomodulator with anti-inflammatory and anti-tumorigenic properties in a range of cancer cell lines, mediated by its action on the cellular cytoskeleton, on mitotic pathways as well as on cellular autophagy.
