MedKoo CAT#: 407864

CAS#: 2196199-00-3

Description: CZh226 is a potent and selective PAK4 inhibitor (PAK4 Ki = 9 nM; PAK1 Ki = 3112 nM). CZh226 showed remarkable PAK4 selectivity (346-fold vs PAK1) and favorable kinase selectivity profile. CZh226 potently inhibited the migration and invasion of A549 tumor cells by regulating the PAK4-directed downstream signaling pathways in vitro. CZh226 as a lead compound for PAK4-targeted anticancer drug discovery and as a valuable research probe for the further biological investigation of group II PAKs.
