Mechanism of Action

Targets/IC₅₀/Ki	Rac1 (MDA-MB-435, MDA-MB-231 cells) 1.1 μM
In vitro	Rac inhibition by EHop-016 increases the activity of the closely related Rho GTPase RhoA by a compensatory mechanism. In MDA-MB-435 cells, this compound (2-5 μM) inhibits association of active Vav2 with Rac1(G15A) mutant fusion protein, and reduces Rac-regulated cell functions including lamellipodia formation and cell migration. In addition, it inhibits cell viability of MDA-MB-435 cells with IC50 of 10 μM. This chemical also inhibits KITD814V-induced growth in SM and AML patients-derived cells.
Kinase Assay	Rac Activity Assays
Kinase Assay	Rac activity is determined from lysates of the MDA-MB-435 and MDA-MB-231 human metastatic cancer cell lines. Cancer cells in culture medium (DMEM, 10% FBS, pH 7.5) are treated with vehicle (0.1% DMSO) or varying concentrations of EHop-016 (0–10 μM) for 24 h. Rac1 activity is determined using the G-LISA Rac1 activation assay kit.
In vivo	Treatment of KITD814V-bearing cells with EHop-016 significantly enhances the survival of leukemic mice.
