体外活性
PF-3644022 potently inhibits TNFα production with similar activity (IC50 of 160 nM), in the human U937 monocytic cell line or peripheral blood mononuclear cells. PF-3644022 blocks TNFα and IL-6 production in LPS-stimulated human whole blood (IC50: 1.6 and 10.3 μM, respectively). 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].
体内活性
PF-3644022 (3-100 mg/kg; oral gavage; twice a day; for 12 days; Lewis rats) treatment displays dose-dependent inhibition of chronic paw swelling. It is measured on day 21 after 12 days of oral dosing (ED50: 20 mg/kg)[1].
