kpt-9274 is a selective and orally bioavailable allosteric inhibitor of pak4 [1][2][3].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 [1][2][3].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) [1]. in rcc cells, kpt-9274 dose-dependently inhibited cell viability [2]. 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 [3].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 [1]. in subcutaneous xenograft mouse models, kpt-9274 inhibited rcc growth [2]. 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 [3]. | [References]
