EHop-016 是一种有效的选择性的Rac GTPase Rac1和Rac3抑制剂。EHop-016 在 MDA-MB-435 细胞中抑制Rac1活性,IC50为 1.1 μM。EHop-016 抑制 Vav2 与 Rac,Rac 激活的 PAK1 相互作用,片状脂蛋白形成和细胞迁移。
生物活性 | EHop-016 is a potent and selectiveRac GTPase Rac1andRac3inhibitor. EHop-016 inhibitsRac1activity with anIC50of 1.1 μM in MDA-MB-435 cells. EHop-016 inhibits Vav2 interaction with Rac, Rac-activatedPAK1, lamellipodia formation, and cell migration[1][2]. |
体外研究 (In Vitro) | EHop-016 (1-10 μM; 24 hours; MDA-MB-435 cells) treatment inhibits Rac1 and Rac3 activity. At higher concentrations, EHop-016 inhibits the close homolog Cdc42. In MDA-MB-435 cells that demonstrate high active levels of the Rac GEF Vav2, EHop-016 inhibits the association of Vav2 with a nucleotide-free Rac1(G15A)[1]. 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[1]. EHop-016 affectes cell viability by down-regulating Akt and Jun kinase activities and c-Myc and Cyclin D expression, as well as increasing caspase 3/7 activities in metastatic cancer cells[2].
