Isoform specificity of different chemical inhibitors of GSK3. Lysates of HCT116p53KO cells were harvested 24 hs after treatment with different GSK3 inhibitors and GSK3A/B activation/inactivation checked by western blot: a mix of pSer21-GSK3A and pSer9-GSK3B antibodies and antibody cross-reacting with both pTyr279-GSK3A and pTyr216-GSK3B were used to assess the specificity of the inhibitor for GSK3A.

|Description||Tideglusib is an irreversible, non ATP-competitive GSK-3β inhibitor with IC50 of 60 nM in a cell-free assay; fails to inhibit kinases with a Cys homologous to Cys-199 located in the active site. Phase 2.|
Tideglusib irreversibly inhibits GSK-3, reduces tau phosphorylation, and prevents apoptotic death in human neuroblastoma cells and murineprimary neurons.  Tideglusib (2.5 μM) inhibits glutamate-induced glial activation as evidenced by decreased TNF-α and COX-2 expression in rat primary astrocyte or microglial cultures. Tideglusib (2.5 μM) also exerts a potent neuroprotective effect on cortical neurons from glutamate-induced excitotoxicity as evidenced by significant reduction in the number of Annexin-V-positive cells in rat primary astrocyte or microglial cultures. 
|In vivo||Tideglusib (50 mg/kg) injected into the adult male Wistar rats hippocampus dramatically reduces kainic acid-induced inflammation and has a neuroprotective effect in the damaged areas of the hippocampus.  Tideglusib (200 mg/kg, oral) results in lower levels of tau phosphorylation, decreased amyloid deposition and plaque-associated astrocytic proliferation, protection of neurons in the entorhinal cortex and CA1 hippocampal subfield against cell death, and prevention of memory deficits in APP/tau double transgenic mice. |

* 1 mg/ml means slightly soluble or insoluble.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.
Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:
Mass (g) = Concentration (mol/L) × Volume (L) × Molecular Weight (g/mol)
*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and MSDS / COA (available on product pages).
Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:
Concentration (start) x Volume (start) = Concentration (final) x Volume (final)
This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )
* When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and MSDS / COA (available online).

Definitions of molecular mass, molecular weight, molar mass and molar weight:
Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.

Frequently Asked Questions
I want to deliver S2823 via i.p. injection, can you suggest one?
This compound can be dissolved in 4% DMSO+corn oil at 2.5 mg/ml clearly. This is the highest concentration, since its solubility in DMSO is pretty low.
