| In Vitro | SB 415286 (SB-415286) inhibits human GSK-3α with an IC50 of 77.5 nM, and a Ki of 30.75 nM. SB-415286 stimulates glycogen synthesis in the Chang human liver cell line with EC50 of 2.9 μM. SB-415286 stimulates glycogen synthase activity in Chang human liver cells. SB-415286 induces transcription of a β-catenin-LEF/TCF regulated reporter gene in HEK293 cells[1]. SB 415286 (SB-415286, 5-44 μM) attenuates B65 cell loss mediated by 1 mM H2O2. SB-415286 (5-44 μM) causes a significant dose-dependent decrease in the fluorescence intensity of DCF, and attenuates B65 ROS production as mediated by 1 mM H2O2. SB-415286 (5-44 μM) also attenuates ROS production in CGN mediated by 1 mM H2O2[2]. SB-415286 (50 µM) induces a substantial suppression of immunoprecipitated GSK3 activity by 97%[3]. |
| Kinase Assay | GSK-3 kinase activity is measured, in the presence or absence of SB-216763 or SB-415286, in a reaction mixture containing final concentrations of: 1 nM human GSK-3α or rabbit GSK3α; 50 mM MOPS pH 7.0; 0.2 mM EDTA; 10 mM Mg-acetate; 7.5 mM β-mercaptoethanol; 5% (w/v) glycerol; 0.01% (w/v) Tween-20; 10% (v/v) DMSO; 28 μM GS-2 peptide substrate. The GS-2 peptide sequence corresponds to a region of glycogen synthase that is phosphorylated by GSK-3. The assay is initiated by the addition of 0.34 μCi [33P]γ-ATP (IC50 determinations) or 2.7 μCi [33P]γ-ATP (Ki determinations). The total ATP concentration is 10 μM (IC50 determinations) or ranges from 0 to 45 μM (Ki determinations). Following 30 min incubation at room temperature the assay is stopped by the addition of one third assay volume of 2.5% (v/v) H3PO4 containing 21 mM ATP. Samples are spotted onto P30 phosphocellulose mats and these are washed six times in 0.5% (v/v) H3PO4. The filter mats are sealed into sample bags containing Wallac betaplate scintillation fluid. 33P incorporation into the substrate peptide is determined by counting the mats in a Wallac microbeta scintillation counter[1]. |
| Cell Assay | B65 cells are used after 24 h of in vitro culture. CGN are used after 7-8 days in vitro. Lithium and SB-415286 are dissolved in culture media and DMSO, respectively, and added to the neuronal preparation at the precise concentrations, 1 h before addition H2O2 (50 μM to 1 mM). To assess the loss in cell viability, we use the MTT [3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium] method. MTT is added to the cells at a final concentration of 250 μM and incubated for 1 h, allowing the reduction in MTT to produce a dark blue formazan product. Media are then removed, and cells are dissolved in dimethylsulfoxide. Formazan production is measured by the absorbency change at 595 nm using a microplate reader. Viability results are expressed as percentages. The absorbency measured from non-treated cells is taken to be 100%[2]. |
