Description

WH-4-023 is a potent and selective Lck and Src inhibitor with IC50 values of 2 and 6 nM, respectively [1]. It is also an inhibitor of IC50 values of 10, 22 and 60 nM for SIK 1, 2 and 3, respectively [2].

Lck and Src are cytoplasmic tyrosine kinases of the Src family expressed in T cells and NK cells [1]. SIKs restrict the formation of regulatory macrophages and that their inhibition greatly stimulates the production of IL-10 and other anti-inflammatory molecules [2].

WH-4-023 inhibited a number of protein tyrosine kinases that possess a Thr residue at the gatekeeper site, such as FGF and Ephrin receptors, Src family members (Src, Lck, and Yes) and BTK. WH-4-023 also inhibited the SIKs and did not inhibit any other member of the AMPK-related kinase subfamily, which all possess a large hydrophobic residue (Met or Leu) at the gatekeeper site. WH-4-023 inhibited SIK 1, 2 and 3 with IC50 values of 10, 22 and 60 nM, respectively. Also, WH-4-023 increased LPS-stimulated IL-10 production and greatly suppressed proinflammatory cytokine secretion [2].

实验参考方法

Kinase experiment[1]:

Lck kinase assays

To determine the inhibitory activity of WH-4-023 against Lck, kinase assays were conducted. The Lck HTRF kinase assay involved ATP-dependent phosphorylation of a biotinylated substrate peptide of gastrin with or without WH-4-023. The final concentration of ATP, gastrin and Lck were 0.5 μM, 1.2 μM and 250 pM, respectively. Buffer were made up as follows: 50 mM HEPES pH=7.5, 2 mM DTT, 5 mM MnCl2, 20 mM MgCl2, 50 mM NaCl, 0.05% BSA. The reaction was quenched and ended by adding 160 μL detection reagent. Detection reagent was prepared as follows: 50 mM Tris, pH=7.5, 3 mM EDTA, 100 mM NaCl, 0.05% BSA, 0.1% Tween-20. Before reading, streptavidin allophycocyanin and anti-phosphotyrosine Ab were added at a final concentration of 0.4 μg/mL and 0.025 nM, respectively. Assay plate was read with excitation at 320 nm and emission at 615 and 655 nm.

Applications

WH-4-023 is a potent and selective Src and Lck inhibitor with IC50 values of 6 and 2 nM, respectively[1].Naive human pluripotent cells were maintained in media containing WH-4-023. WH-4-023 improves the fraction of viable GFP+ cells. Withdrawal of the WH-4-023 results in a change in morphology and slight decrease of OCT4-DPE-GFP reporter activity[2].
