Description: EHop-016 is a novel potent and selective inhibitor of RAC. EHop-016 inhibits Rac activity in the MDA-MB-435 metastatic cancer cells that overexpress Rac and exhibits high endogenous Rac activity. The IC(50) of 1.1 μM for Rac inhibition by EHop-016 is ~ 100-fold lower than for NSC23766. EHop-016 is specific for Rac1 and Rac3 at concentrations of < 5 μM. At higher concentrations, EHop-016 inhibits the close homolog Cdc42. EHop-016 also inhibits the Rac activity of MDA-MB-231 metastatic breast cancer cells and reduces Rac-directed lamellipodia formation in both cell lines. EHop-016 decreases Rac downstream effects of PAK1 (p21-activated kinase 1) activity and directed migration of metastatic cancer cells. EHop-016 holds promise as a targeted therapeutic agent for the treatment of metastatic cancers with high Rac activity.
