Background

Cucurbitacin E, a widely available plant-derived natural product, is a useful tool to study actin dynamics in cells and actin-based processes such as cytokinesis [1].

In vitro: In assays using pure fluorescently labeled actin, Cucurbitacin E affected depolymerization without affecting the polymerization. It inhibited actin depolymerization at substoichiometric concentrations up to 1:6 cucurbitacin E:actin. Cucurbitacin E specifically bound to F-actin to form a covalent bond at residue Cys257, but not to monomeric actin (G-actin) [1]. In human leukemia HL-60 cells, Cucurbitacin E (3-50 nmol/l) inhibited the growth of HL-60 cells. At high concentrations (1-10 mol/l), Cucurbitacin E induced apoptosis of HL-60 cells and activation of caspase-3, 8 and 9. Jurkat leukemia cells with or without caspase-8 expression were nearly equally sensitive to cucurbitacin E-induced apoptosis[2]. Cucurbitacin E disrupted the actin cytoskeleton. In a series of cucurbitacin analogues, the anti-proliferative activity was correlated with the disruption of the F-actin cytoskeleton directly [3].
