KPT-9274 is a selective and orally bioavailable allosteric inhibitor of PAK4 . P21 protein (Cdc42/Rac)-activated kinase 4 (PAK4) is a serine/threonine-protein kinase and a member of the PAK family of proteins which are Rac1 and Cdc42 effectors. PAK4 is a mediator of filopodia formation and stabilizes β-catenin transcriptional activity, and is involved in disease progression for several solid tumors . KPT-9274 is a selective and orally bioavailable PAK4 inhibitor. In MDA-MB-468 cells, KPT-9274 showed anti-tumor activity with IC50 value of 0.12 μM. KPT-9274 reduced PAK4 protein and the key downstream effectors of cell cycle (β-catenin, cyclin D1), cell migration (cofilin), autophagy (AMPK) and apoptosis (Caspase and PARP cleavage) . In RCC cells, KPT-9274 dose-dependently inhibited cell viability . In AML cell lines, KPT-9274 (1 nM-10 μM) inhibited cell proliferation in a dose-and time- dependent way and reduced protein and mRNA expression of PAK4 . In mice inoculated with MDA-MB-231 or MDA-MB-468 cells, KPT-9274 were given orally once daily (5 or 7 days/week) without major toxicity. KPT-9274 induced a maximum TGI of ~55% and ~70% in MDA-MB-231 and MDA-MB-468 mice, respectively . In subcutaneous xenograft mouse models, KPT-9274 inhibited RCC growth . In human AML leukemia xenograft model, KPT-9274 (150 mg/kg) significantly inhibited tumor growth, prevented invasion of MV4-11 cells, and improved overall survival .
