NVS-PAK1-1 is a potent allosteric inhibitor of p21-activated kinase PAK1, a serine-threonine kinase that is upregulated in many cancers. NVS-PAK1-1 has an IC50 value of 5 nM for dephoshorylated PAK1 and 6 nM for phosphorylated PAK1 in an in vitro dephosphorylation assay. NVS-PAK1-1 showed good selectivity against 442 other kinases including PAK2. NVS-PAK1-1 has generally good physicochemical properties, but was metabolized by rat liver microsomes, so may not be useful for in vivo work.
