A potent and selective group I PAK (pan-PAK1/2/3) inhibitor with Ki of 0.95/2 nM for PAK1/2, respectively.

CZh226 hydrochloride (CZh-226) is a potent, selective inhibitor of p21-activated kinase 4 (PAK4) with Ki of 9 nM, displays 346-fold selectivity over PAK-1.

CZh226 hydrochloride (CZh-226) is a potent, selective inhibitor of p21-activated kinase 4 (PAK4) with Ki of 9 nM, displays 346-fold selectivity over PAK-1.

FRAX1036 is a novel ATP-competitive small molecule inhibitor of group I p21-activated Kinases (PAKs).

FRAX597 is a small molecule inhibitor of the p21-activated kinases, inhibits tumorigenesis of neurofibromatosis type 2 (NF2)-associated Schwannomas.

PAK4-IN-1 is an inhibitor of p21-activated kinases (PAKs), with IC50 of ≤100 nM in MTT assay.

PF-03758309 is an orally bioavailable small-molecule inhibitor of p21-activated kinase 4 (PAK4) with potential antineoplastic activity.

PF-3758309 dihydrochloride is a potent, orally available, and reversible ATP-competitive inhibitor of PAK4 (Kd= 2.7 nM; Ki=18.7 nM). PF-3758309 dihydrochloride has the expected cellular functions of a PAK4 inhibitor: inhibition of anchorage-independent growth, induction of apoptosis, cytoskeletal remodeling, and inhibition of proliferation.

IPP-14 is a novel PAK1 inhibitor that selectively blocks the PAK1-PUMA binding and suppresses cell proliferation via PUMA-dependent manner; suppresses cancer cell viability and migration, induces p21 expression and induces M-phase arrest by inhibition of PAK1; also induces p21/WAF1/CIP1 (Cyclin-dependent kinase inhibitor 1A) expression by releasing from Bcl-2 and by inhibition of AKT-mediated p21 suppression.

AZ13705339 hemihydrate is a highly potent and selective PAK1 inhibitor with IC50s of 0.33 nM and 59 nM for PAK1 and pPAK1, respectively. AZ13705339 hemihydrate has binding affinities to PAK1 and PAK2, with Kds of 0.28 nM and 0.32 nM, respectively. AZ13705339 hemihydrate can be used in the research of cancers.
