PF-3644022 is a potent, selective, orally active and ATP-competitive MAPKAPK2 (MK2) inhibitor with an IC50 of 5.2 nM and a Ki of 3 nM. PF-3644022 also inhibits MK3 and p38 regulated/activated kinase (PRAK) with IC50s of 53 nM and 5.0 nM, respectively. PF-3644022 potently inhibits TNFα production and has anti-inflammatory effect[1].

IC50: 5.2 nM (MK2), 5.0 nM (PRAK) and 53 nM (MK3)[1]. Ki: 3 nM (MK2)[1] |
| In Vitro | The inhibitory activity of PF-3644022 against other MAPKAP kinase family members is evaluated. Other than MNK2 with an IC50 of 148 nM, other family members are largely not inhibited, showing at least several hundred-fold selectivity versus MK2[1]. In the human U937 monocytic cell line or peripheral blood mononuclear cells, PF-3644022 potently inhibits TNFα production with similar activity (IC50 of 160 nM). PF-3644022 blocks TNFα and IL-6 production in LPS-stimulated human whole blood with IC50 values of 1.6 and 10.3 μM, respectively. Inhibition of TNFα in U937 cells and blood correlates closely with inhibition of phospho-heat shock protein 27, a target biomarker of MK2 activity[1]. |
| In Vivo | PF-3644022 (3-100 mg/kg; oral gavage; twice a day; for 12 days; Lewis rats) treatment shows dose-dependent inhibition of chronic paw swelling measured on day 21 after 12 days of oral dosing, with ED50 value of 20 mg/kg[1]. Animal Model: Female Lewis rats (125-140 g) injected with streptococcal cell wall[1] Dosage: 3 mg/kg, 10 mg/kg, 30 mg/kg, 50 mg/kg, 100 mg/kg Administration: Oral gavage; twice a day; for 12 days Result: Showed dose-dependent inhibition of chronic paw swelling measured on day 21 after 12 days of oral dosing. |
