|Description||AR-A014418 (GSK-3β Inhibitor VIII) is an ATP-competitive, and selective GSK3β inhibitor with IC50 and Ki of 104 nM and 38 nM in cell-free assays, without significant inhibition on 26 other kinases tested.|
|Features||Cell-permeable GSK3-selective inhibitor.|
AR-A014418 inhibits tau phosphorylation at a GSK3-specific site (Ser-396) in 3T3 fibroblasts expressing human four-repeat tau protein with IC50 of 2.7 μM, and protects cultured N2A cells from death induced by blocking PI3K/PKB pathway. In hippocampal slices, AR-A014418 inhibits neurodegeneration mediated by beta-amyloid peptide.  While in NGP and SH-5Y-SY cells, AR-A014418 reduces neuroendocrine markers and suppresses neuroblastoma cell growth. 
|In vivo||In ALS mouse model with the G93A mutant human SOD1, AR-A014418 (0-4 mg/kg, i.p.) delays the onset of symptoms, improves motor activity, slows down disease progression, and postpons the endpoint of the disease.  In addition, AR-A014418 produces inhibition effect on acetic acid- and formalin-induced nociception in mice by modulating NMDA and metabotropic receptor signaling as well as TNF-α and IL-1β transmission in the spinal cord. |
GSK3 Scintillation Proximity Assay:The competition experiments are carried out in duplicate with 10 concentrations of the inhibitor in clear-bottomed microtiter plates. The biotinylated peptide substrate, biotin-AAEELDSRAGS(PO3H2)PQL, is added at a final concentration of 2 μM in an assay buffer containing 6 milliunits of recombinant human GSK3 (equal mix of both α and β), 12 mM MOPS, pH 7.0, 0.3 mM EDTA, 0.01% β-mercaptoethanol, 0.004% Brij 35, 0.5% glycerol, and 0.5 μg of bovine serum albumin/25 μl and preincubated for 10-15 min. The reaction is initiated by the addition of 0.04 μCi of [γ-33P]ATP and unlabeled ATP in 50 mM Mg(Ac)2 to a final concentration of 1 μM ATP and assay volume of 25 μl. Blank controls without peptide substrate are used. After incubation for 20 min at room temperature, each reaction is terminated by the addition of 25 μl of stop solution containing 5 mM EDTA, 50 μM ATP, 0.1% Triton X-100, and 0.25 mg of streptavidin-coated SPA beads corresponding to ∼35 pmol of binding capacity. After 6 h the radioactivity is determined in a liquid scintillation counter. Inhibition curves are analyzed by non-linear regression using GraphPad Prism.

1.Please make sure the liquid is clear before adding the next solvent.
2.Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such as vortex, ultrasound or hot water bath can be used to aid dissolving.
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)
*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and SDS / 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 SDS / 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.
