PF-3758309 is a pyrrolopyrazole inhibitor of PAK4 (p21-activated kinase). It is used in biological studies for targeting Rho GTPase signaling for cancer therapy. | [Definition]
ChEBI: N-[(1S)-2-(dimethylamino)-1-phenylethyl]-6,6-dimethyl-3-[(2-methyl-4-thieno[3,2-d]pyrimidinyl)amino]-1,4-dihydropyrrolo[3,4-c]pyrazole-5-carboxamide is an organic heterobicyclic compound, an organosulfur heterocyclic compound and an organonitrogen heterocyclic compound. | [Biological Activity]
pf-3758309 is an inhbitor of pak4 with ic50 of 1.3 nm [1].p21-activated kinases (paks) are the family of serine/theronine kinases, which play important role in linking rho gtpase to cytoskeleton reorganization and nuclear signaling. pak4 is a member of paks family, specifically responsive for interacting with gtp bound form of cdc42 and jnk family. pak4 is involved in filopodia formation and may play a role in the reorganization of the actin cytoskeleton.biochemical study had identified that pf-3758309 was an atp-competitive inhibitor of pak4, which inhibited the kinase activity [1]. when pak4 was screened with a panel of tumor cell lines, it was found pf-3758309 inhibited the phosphorylation of pak4 substrate gef-h1, and also the pak4-induced anchorage-independent cell growth, with ic50 value of 1.3 nm and 4.7 ±3 nm respectively [1]. when pf-3758309 was screened with a panel of paks related kinases, it exhibited good potency and specificity for pak4 [1]. cell analysis con?rmed that pf-3758309 modulates pak4-dependent signaling nodes and identi?es unexpected links to additional p53pathways [1]. | [in vivo]
activity of pf-3758309 was examined in a panel of human xenograft model, including hct116 and a549 model. twice daily oral administration of pf-3758309 (7.5-30 mg/kg bid) for 9-18 days resulted in significant inhibition of tumor growth in all the models. the tumor growth was shown to be caused by pak-dependent pathways in hct116 and a549 model. additionally, pf-3758309 was shown to regulate pak-associated cell proliferation and survival in certain models. therefore, pf-3758309 exhibited inhibitory activity on pak4 [1]. | [IC 50]
PAK4: 18.7 nM (Ki); PAK1: 13.7 nM (Ki); PAK5: 18.1 nM (Ki); PAK6: 17.1 nM (Ki); PAK2: 190 nM (IC50); PAK3: 99 nM (IC50); PAK4: 2.7 nM (Kd) | [storage]
