1 Customer Review
Human glioma U87MG cells (A-C) and U251MG cells (D), as well as HCN-1a neuronal cells (D) or primary human astrocytes (“Astrocytes”, D) were either left untreated (“C”) or treated with applied concentrations of GSK621 for indicated periods of time, cell survival was tested by MTT assay (A and D) and clonogenicity assay (B); Cell death was also tested by the trypan blue staining assay (C). Experiments in this figure were repeated four times, and similar results were obtained. Data were presented as mean ± SD. * p <0.05 vs. “C”.

|Description||GSK621 is a specific and potent AMPK activator.|
In AML cell lines and primary AML samples, GSK621 markedly increases phosphorylation at AMPKα T172, a marker of AMPK activation. In a set of 20 cell lines, GSK621 reduces the proliferation of all 20 lines with IC50 ranged from 13-30 μM, and increases apoptosis in 17 (85%) lines. In addition, GSK621 also triggers autophagy, which partially contributes to AML cell death. 
|In vivo||In nude mice bearing MOLM-14 xenografts, GSK621 (30 mg/kg, i.p.) reduces leukemia growth and significantly extends survival by enhancing AMPK activity and the induction of apoptosis. |
AMPK enzymatic assay:HEPG2 cells are treated with increasing doses of A-769662 or GSK621, and ACC S79 phosphorylation is assessed as a surrogate marker for AMPK activation using a commercially available ELISA kit.
|In vitro||DMSO||97 mg/mL (197.99 mM)|
|In vivo||Add solvents to the product individually and in order(Data is from Selleck tests instead of citations):
2% DMSO+30% PEG 300+5% Tween 80+ddH2O
For best results, use promptly after mixing.
* 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.
