Description: Group II PAK inhibitor; potently inhibits PAK4 and PAK 6
Chemical Name: 1-[2-[1-(2-Amino-4-pyrimidinyl)-2-[(2-methoxyethyl)amino]-1H-benzimidazol-6-yl]ethynyl]cyclohexanol
Purity: ≥98% (HPLC)
Biological Activity
Inhibitor of group II p21 activated kinases (PAK; IC50 values are 7.5, 126 and 36 nM for PAK4, PAK5 and PAK6, respectively). Displays selectivity for group II PAK over a panel of 222 kinases. Inhibits tumor cell proliferation, migration and invasion in two breast cancer cell lines. Also sensitizes tamoxifen-resistant breast cancer cell lines to tamoxifen (Cat. No. 6342) via PAK4-dependent regulation of estrogen receptor α (ERα) target gene expression.
