PF-3644022
PF-3644022 is a potent and selective mitogen-activated protein kinase (MAPK)-activated protein kinase-2 (MK2) inhibitor (Ki =3 nM). [1]
PF-3644022 is the first oral MK2 inhibitor in both acute and chronic models of inflammation. PF-3644022 reversibly ATP-competitive inhibits MK2 enzyme activity with good selectivity across 200 human kinases. [1]
In the human U937 monocytic cell line or peripheral blood mononuclear cells, PF-3644022 potently inhibits TNF production with IC50 value of 160 nM. In LPS-stimulated human whole blood, PF-3644022 blocks TNF and IL-6 production with IC50 values of 1.6 and 10.3 μM, respectively. In U937 cells and blood, Inhibition of TNF correlates closely with inhibition of phospho-heat shock protein 27, a target biomarker of MK2 activity. [1]
In the rat LPS-induced TNF model, PF-3644022 efficacy in the chronic inflammation model is strongly correlated with maintaining a Cmin higher than the EC50 measured. PF-3644022 exhibits efficaciously oral activity and good pharmacokinetic parameters in both the chronic streptococcal cell wall-induced arthritis model and the rat acute LPS-induced TNF model. [1]
