General description
G-5555 is a selective p21-activated kinase (PAK1) inhibitor. In addition to this it also selectively inhibits eight kinases such as PAK2, PAK3, KHS1, lymphocyte-specific protein tyrosine kinase (LcK), Mammalian Ste20-like kinase 3 (MST3), Mammalian Ste20-like kinase 4 (MST4), salt-inducible kinase 2(SIK2), and Yeast Sps1/Ste20-related Kinase 1 (YSK1). G-5555 exhibits high stability and low human ether-à-go-go related gene (hERG) activity than other PAK inhibitors including FRAX1036.
Biochem/physiol Actions
G-5555 is an ATP site-targeting inhibitor against salt-inducible kinases, MST3/4, p21-activated kinase 1/2, YANK1/3, MAP2K5, MAP4K5 (% inhibition at 100 nM = 98.6/93.5/99.8 (SIK1/2/3), 85/99.5 (MST3/4), 95.6/87 (PAK1/2), 94.7/96.5 (YANK1/3); 87/MAP2K5, 83/MAP4K5) with good selectivity over other kinases. G-5555 downregulates MEK pS298 in EBC1 cells in cultures (IC50 = 69 nM) and in H292 NSCLC tumors in mice in vivo (25 mg/kg p.o.) with good oral availability (mice F = 80%, monkeys F = 72%).

PAK1 plays a crucial role in cancer progression, inhibiting this protein has the potential to reduce cancer development. Therefore, G-5555 may be a promising candidate for oncology research.

Signaling pathways intersecting with the p21-activated kinases (PAKs) play important roles in tumorigenesis and cancer progression. By recognizing that the limitations of FRAX1036 (1) were chiefly associated with the highly basic amine it contained, we devised a mitigation strategy to
