Biological Activity

Description SB216763 is a potent and selective GSK-3 inhibitor with IC50 of 34.3 nM for GSK-3α and equally effective at inhibiting human GSK-3β. SB216763 activates autophagy.
Targets
GSK-3α [1]
(Cell-free assay)		 GSK-3β [1]
(Cell-free assay)
34.3 nM ~34.3 nM
In vitro SB 216763 displays similar potency for GSK-3β with 96% inhibition at 10 μM while exhibiting minimal activity against 24 other protein kinases including PKBα and PDK1 with IC50 of >10 μM. SB 216763 stimulates glycogen synthesis in human liver cells with EC50 of 3.6 μM, and induces dose-dependent transcription of a β-catenin-LEF/TCF regulated reporter gene in HEK293 cells with a maximum 2.5-fold induction at 5 μM. [1] SB 216763 protects the cerebellar granule neurones from apoptotic cell death induced by LY-294002 or potassium-deprivation in a concentration-dependent manner, with a maximal neuroprotection at 3 μM in contrast with the effect of lithium chloride at which 10 mM is required. SB 216763 at 3 μM also completely prevents death of chicken dorsal root ganglion sensory neurones induced by LY-294002 regardless of NGF. SB 216763 treatment at 5 μM markedly inhibits the GSK-3-dependent phosphorylation of neuronal-specific microtubule-associated protein tau in cerebellar granule neurones or recombinant tau in HEK293 cells, and induces increased levels of cytoplasmic β-catenin in both cells mimicking the effect of Wnt-mediated inhibition of GSK-3. [2] In pancreatic cancer cell lines including BXPC-3, MIA-PaCa2, PANC1, ASPC1, and CFPAC, SB 216763 treatment at 25-50 μM reduces cell viability in a dose-dependent manner, and leads to significant increase in apoptosis by 50% at 72 hours due to the specific down regulation of GSK-3β, while has no effect in HMEC or WI38 cell lines. [3]
In vivo Administration of SB 216763 at 20 mg/kg significantly prevents lung inflammation and the subsequent fibrosis in bleomycin (BLM)-induced pulmonary inflammation and fibrosis model in mice by significantly blocking the production of inflammatory cytokines MCP-1 and TNF-α by macrophages, and significantly improves the survival of BLM-treated mice. SB 216763 treatment causes a significant reduction in BLM-induced alveolitis by inhibiting alveolar epithelial cell damage. [4]

Protocol (from reference)

Kinase Assay:[1]
  • GSK-3 activity assay

    GSK-3 kinase activity is measured, in the presence of various concentrations of SB 216763, in a reaction mixture containing final concentrations of 1 nM human GSK-3α, 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, and 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. The total ATP concentration is 10 μM. Following 30 minutes 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 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.
Cell Assay:[3]
  • Cell lines

    BXPC-3, MIA-PaCa2, PANC1, ASPC1, and CFPAC cells

  • Concentrations
