Biochem/physiol Actions

FRAX1036 is a potent, group I-selective p21-activated kinase (PAK) inhibitor (PAK1/4 Ki = 23 nM/1.4 μM; PAK1/4 IC50 = 2 nM/>500 nM; >96% PAK1/2/3 inhibition vs. 5.1%/8.2%/22.2% PAK4/5/6 inhibition at 1 μM) with significant inhibitory activity toward only 11 other kinases at a high concentration of 1 μM (78.7-100% inhibition) among a panel of 240. FRAX1036 exhibits higher antiproliferation activity in PAK negative regulator NF2-deficient meningioma cultures (NF2-/- Ben-Men-1/KT21-MG1 IC50 = 1.888/1.991 μM vs.NF2+/+ MN328/MN525 IC50 = 4.239/3.296 μM) by inhibiting cellular PAK autophosphorylation and downstream signaling events. When administered orally in a murine orthotopic meningioma model, FRAX1036 effectively suppresses the growth of established KT21 and Ben-Men tumors in vivo (30 mg/kg/d p.o.).

The p21-activated kinases (PAKs) are Cdc42/Rac-activated serine-threonine protein kinases that regulate several key cancer-relevant signaling pathways, such as the Mek/Erk, PI3K/Akt, and Wnt/β-catenin cascades. Pak1 is frequently overexpressed and/or hyperactivated in different human cancers, including breast, ovary, prostate, and brain

Malignant peripheral nerve sheath tumors (MPNSTs) are devastating sarcomas for which no effective medical therapies are available. Over 50% of MPSNTs are associated with mutations in NF1 tumor suppressor gene, resulting in activation of Ras and its effectors, including the

p21-activated kinases (Paks) have been shown to regulate cytoskeleton rearrangements, cell proliferation, attachment, and migration in a variety of cellular contexts, including endothelial cells. However, the role of endothelial Pak in embryo development has not been reported, and currently, there

Activating mutations in the RAC1 gene have recently been discovered as driver events in malignant melanoma. Expression of this gene is associated with melanocyte proliferation, and melanoma cells bearing this mutation are insensitive to BRAF inhibitors such as vemurafenib and

Key effector(s) of mutated KRAS in lung cancer progression and metastasis are unknown. Here we investigated the role of PAK1/Crk axis in transduction of the oncogenic KRAS signal in non-small cell lung cancer (NSCLC). We used NSCLC clinical specimens to
