CZh226 is a potent and selective PAK4 inhibitor (PAK4 Ki = 9 nM; PAK1 Ki = 3112 nM). CZh226 potently inhibits the migration and invasion of A549 tumor cells by regulating the PAK4-directed downstream signaling pathways in vitro.
SPU-106 is a novel specific PAK4 inhibitor, effectively inhibiting the invasion of SGC7901 cells without cytotoxicity, regulating the PAK4/LIMK1/cofilin and PAK4/SCG10 signaling pathways.
