Biological Activity

Description Tideglusib (NP031112, NP-12) 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.

In vitro

Tideglusib irreversibly inhibits GSK-3, reduces tau phosphorylation, and prevents apoptotic death in human neuroblastoma cells and murineprimary neurons. [1] 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.

GSC11 cells were treated with 2.5 µM or 5 µM tideglusib for 36 h, and cell lysates were assessed by immunoblotting.

(e) GSC11 and GSC20 cells were treated with different concentration of tideglusib for 7d. IC50 values for each cell line were calculated using the GraphPad Prism 6 software (mean ± s.e.m., n=3 independent experiments). (f) GSC11 and GSC20 cells were treated with dimethyl sulfoxide (DMSO), temozolomide (TMZ; 100 µM), tideglusib (2.5 µM), or TMZ plus tideglusib for the indicated times, and cell proliferation was assessed by XTT assays (mean ± s.e.m., n=3 independent experiments, paired Student’s t-test). P values were analyzed by comparing TMZ or tideglusib along versus the combination of the two and shown. 

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. [2] 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.

Bio Calculators

Molarity Calculator

Molarity Calculator

Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:

Mass (mg) = Concentration (mM) × Volume (mL) × Molecular Weight (g/mol)

  • Mass
    Molecular Weight

*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).

Dilution Calculator

Dilution Calculator

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 )

  • C1

* 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

  • Question 1:

    I want to deliver S2823 via i.p. injection, can you suggest one?

  • Answer:

    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.
