Description
A cell-permeable pyrimidine compound that specifically and reversibly inhibits Rac1 GDP/GTP exchange activity by interfering their interaction with the Rac-specific GEF (guanine nucleotide exchange factor) Trio and Tiam1 (IC50~50 µM). Shown to effectively inhibit Rac1-mediated cellular functions in NIH3T3 and PC-3 cells (effective dose ~50 to 100 µM). Exhibits no effect on Cdc42 or RhoA activation, and does it affect Rac1 interaction with BcrGAP or PAK1.
