产品介绍

PF-3644022 是一种有效的，选择性的，口服活性的，具有 ATP 竞争性的MAPKAPK2 (MK2)抑制剂，IC₅₀为 5.2 nM，K_i为 3 nM。PF-3644022 还抑制 MK3 和 p38 调节/激活激酶 (PRAK)，IC₅₀分别为 53 nM 和 5.0 nM。PF-3644022 有效抑制 TNFα 的产生并具有抗炎作用。

生物活性

PF-3644022 is a potent, selective, orally active and ATP-competitiveMAPKAPK2 (MK2)inhibitor with anIC₅₀of 5.2 nM and aK_iof 3 nM. PF-3644022 also inhibits MK3 andp38 regulated/activated kinase (PRAK)withIC₅₀s of 53 nM and 5.0 nM, respectively. PF-3644022 potently inhibits TNFα production and has anti-inflammatory effect^[1].

IC₅₀& Target

IC50: 5.2 nM (MK2), 5.0 nM (PRAK) and 53 nM (MK3)^[1].
Ki: 3 nM (MK2)^[1]

体外研究
(In Vitro)

The inhibitory activity of PF-3644022 against other MAPKAP kinase family members is evaluated. Other than MNK2 with anIC₅₀of 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 (IC₅₀of 160 nM). PF-3644022 blocks TNFα and IL-6 production in LPS-stimulated human whole blood withIC₅₀values 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].

体内研究
