GSK583 (1 μM) exhibits excellent selectivity in a panel of 300 kinases, including p38α and VEGFR2. GSK583 potently and dose dependently inhibits MDP-stimulated tumor necrosis factor-alpha (TNFα) production with an IC50 of 8 nM. GSK583 demonstrates only a modest reduction in potency when profiled in a similar MDP-induced TNFα production assay in human whole blood (IC50 = 237 nM) and rat whole blood (IC50 = 133 nM)[1].

Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

Protocol
A fluorescent polarization based binding assay is developed to quantitate interaction of novel test compounds at the ATP binding pocket of RIP2K by competition with a fluorescently labeled ATP competitive ligand. Full length FLAG His tagged RIP2K is purified from a baculovirus expression system and is used at a final assay concentration of twice the KD apparent. A fluorescent labeled ligand that is reversible and competitive with the inhibitors is used at a final assay concentration of 5 nM. Both the enzyme and ligand are prepared in solutions in 50 mM HEPES pH 7.5, 150 mM NaCl, 10 mM MgCl2, 1 mM DTT, and 1 mM CHAPS. Test compounds are prepared in 100% DMSO, and 100 nL is dispensed to individual wells of a multiwell plate. Next, 5 μL of RIP2K is added to the test compounds at twice the final assay concentration and incubated at room temperature for 10 min. Following the incubation, 5 μL of the fluorescent labeled ligand solution is added to each reaction at twice the final assay concentration and incubated at room temperature for at least 10 min. Finally, samples are read on an instrument capable of measuring fluorescent polarization. Test compound inhibition is expressed as percent (%) inhibition of internal assay controls. For concentration response experiments, normalized data are fit using the following four parameter logistic equation: y = A + ((B-C))/(1+(10x)/(10C)D), where y is the % activity (% inhibition) at a specified compound concentration, A is the minimum % activity, B is the maximum % activity, C = log10(IC50), D = Hill slope, x = log10(compound concentration [M]), and pIC50 = (−C).

Mice[1]
Female C57Bl/6 mice (for cytokine analyses) or male Balb/c mice (for peritoneal neutrophil analyses) (n=10/treatment group) are dosed orally 15 min prior to MDP challenge with vehicle or GSK583 (0.1, 1, or 10 mg/kg). For peritoneal neutrophil analysis, mice are sacrificed at 4 h post-MDP challenge (30 μg, i.p.) and peritoneal fluid is collected by lavage. Peritoneal neutrophils are quantified by FACS analysis.
Rats[1]
Female Crl:CD(SD) rats (n=8/treatment group) are dosed orally with vehicle or GSK583 15 min prior to MDP challenge (150 μg/rat, IV). At 2 h post MDP challenge, rats are sacrificed and terminal serum is prepared from blood collected via cardiac stick. Serum cytokine levels (IL-6, IL-8 or KC, IL-1β, and TNFα) are quantified by the MSD platform.
