Mechanism of Action

Features	PF-3758309 is potent toward a broad array of tumor cell lines from different tumor types.
Targets/IC₅₀/Ki	PAK1 (Cell-free assay) 13.7 nM(Ki) PAK6 (Cell-free assay) 17.1 nM(Ki) PAK5 (Cell-free assay) 18.1 nM(Ki) PAK4 (Cell-free assay) 18.7 nM(Ki) PAK3 (Cell-free assay) 99 nM PAK2 (Cell-free assay) 190 nM
In vitro	PF-3758309 is a potent (K_d = 2.7 nM), ATP-competitive inhibitor of PAK4 with K_i of 18.7 nM. In cells, this compound inhibits phosphorylation of the PAK4 substrate GEF-H1 (IC50 = 1.3 nM) and anchorage-independent growth of a panel of tumor cell lines (IC50 = 4.7 nM). It also inhibits endogenous pGEF-H1 accumulation in HCT116 cells. This chemical potently inhibits cellular proliferation (IC50 = 20 nM) and anchorage-independent growth (IC50 = 27 nM) of A549 cells.
Kinase Assay	Phospho-GEF-H1 Cellular Assay
Kinase Assay	TR-293-KDG cells are constructed from HEK293 cells stably transfected with tetracycline-inducible PAK4-kinase domain (amino acids 291-591) and constitutively expressed HA-tagged GEFH1ΔDH (amino acids 210-921). TR-293-KDG cells are incubated for 3 h with PF-3758309, captured on an anti-HA antibody-coated plate, detected with an anti-phospho-S810-GEF-H1 antibody, and quantified with a horseradish peroxidase-goat anti-rabbit antibody conjugate.
In vivo	PF-3758309 blocks the growth of multiple human tumor xenografts, with a plasma EC50 value of 0.4 nM in the most sensitive model. This compound is antiproliferative and induces apoptosis in a HCT116 tumor model.
