PF-3758309 (PF-03758309) hydrochloride is a potent, orally available, and reversible ATP-competitive inhibitor of PAK4 (K_d= 2.7 nM; K_i=18.7 nM). PF-3758309 hydrochloride has the expected cellular functions of a PAK4 inhibitor: inhibition of anchorage-independent growth, induction of apoptosis, cytoskeletal remodeling, and inhibition of proliferation.

In Vitro

PF-3758309 hydrochloride has similar enzymatic potency against the kinase domains of the other group B PAKs (PAK5, K_i=18.1 nM; PAK6, K_i=17.1 nM) and group A PAK1 (K_i=13.7 nM), but is less active against the other two group A PAKs (PAK2, IC₅₀=190 nM; PAK3, IC₅₀=99 nM)^[1].
In cells, PF-3758309 hydrochloride 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)^[1].
PF-3758309 hydrochloride also inhibits endogenous pGEF-H1 accumulation in HCT116 cells. PF-3758309 potently inhibits cellular proliferation (IC₅₀=20 nM) and anchorage-independent growth (IC₅₀=27 nM) of A549 cells^[1].

In Vivo

PF-3758309 hydrochloride (7.5-30 mg/kg; p.o.; twice daily for 9-18 days) results in statistically significant tumor growth inhibition (TGI) in HCT116 and A549 models^[1].

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
