In vitro
In vitro	SP600125 is originally characterized as a selective ATP-competitive inhibitor of c-Jun N-terminal kinase JNK. In Jurkat T cells, SP600125 inhibits the phosphorylation of c-Jun with IC50 of 5 μM to 10 μM. In CD4+ cells, such as Th0 cells isolated from either human cord or peripheral blood, SP600125 blocks cell activation and differentiation and inhibits the expression of inflammatory genes COX-2, IL-2, IL-10, IFN-γ, and TNF-α, with IC50 of 5 μM to 12 μM. ^[1] However, later studies reveal that SP600125 also suppresses aryl hydrocarbon receptor (AhR) ^[2], Mps1 ^[3], and a panel of other serine/threonine kinases, including Aurora kinase A, FLT3, MELK, and TRKA ^[4]. In a mouse beta cells MIN6, SP600125 (20 μM) induces the phosphorylation of p38 MAPK and its downstream CREB-dependent promoter activation. ^[5] In HCT116 cells, SP600125 (20 μM) blocks the G2 phase to mitosis transition and induces endoreplication. This ability of SP600125 is independent of JNK inhibition, but due to its inhibition of CDK1-cyclin B activation upstream of Aurora A and Polo-like kinase 1. ^[6]
Kinase Assay	In Vitro Kinase Assays
Kinase Assay	The potency of SP600125 towards kinases, including MPS1, JNK, and Aurora kinase A, is determined based on the specific measurement of radioactive phosphotransfer to the substrate. For each enzyme, the absolute K_m values for ATP and the specific substrate are initially determined and each assay is then run at optimized [ATP] (2·αK_m) and [substrate] (5·K_m) concentrations. MPS1 activity is measured using 5 nM of MPS1 recombinant protein in 50 mM HEPES pH 7.5, 2.5 mM MgCl₂, 1 mM MnCl₂, 1 mM DTT, 3 μM NaVO₃, 2 mM β-glycerophosphate, 0.2 mg/mL BSA, 200 μM P38-βtide substrate-peptide (KRQADEEMTGYVATRWYRAE), and 8 μM ATP with 1.5 nM ³³P-γ-ATP. Ten serial 1:3 dilutions (from 30 μM to 1.5 nM) of SP600125 are tested and IC50 determined.
Cell Research	Cell lines	HCT116, A2780, and U2OS cells
	Concentrations	0–5 μM
	Incubation Time	72 hours
	Method	Cells are seeded in 384 well-plates. One day after seeding, the cells are treated with SP600125 for 72 hours and the plates are then processed using a CellTiter-Glo assay. Inhibitory activity is evaluated comparing treated versus control data and IC50 value of proliferation is calculated.
