4 Customer Reviews
iKras p53L/+ cells were treated with AZD8330 (50 nM), BKM120 (150 nM), or Rapamycin (20 nM) for 18 hr. As control, cells were cultured in the presence or absence of doxycycline for 24 hr, and cell lysates were blotted for phospho-Akt, phospho-Erk, phospho-S6, and Myc.

(B) MEK inhibition suppressed proliferation of lung cancer cells harboring mutant or wild-type EGFR. A549 and PC-9 cells were incubated in the presence of various concentrations of AZD-8330 or TAK-733. Cell extracts were prepared after 1 h of treatment and immunoblotted with the indicated antibodies (upper panel). Cell growth was measured by MTT assay after 72 h (lower panel).

Effect of MEK inhibitor AZD-8330 in A549 cells. A549 cells were incubated with increasing concentrations of AZD-8330 for 2 h. The cell lysates were harvested and phosphorylation of indicated proteins was determined by Western blotting.

|Description||AZD8330 is a novel, selective, non-ATP competitive MEK 1/2 inhibitor with IC50 of 7 nM. Phase 1.|
AZD8330 potently and strongly inhibits MEK 1/2. AZD8330 has no inhibitory activity against over 200 other kinases including at concentrations up to 10 μM. AZD8330 demonstrates sub-nanomolar potency in mechanistic (pERK) and low to sub-nanomolar potency in functional (proliferation) assays in MEK 1/2 inhibitor sensitive cell lines. 
|In vivo||In a Calu-6 rat xenograft pharmacokinetic/pharmacodynamic (PK/PD) model a single, 1.25 mg/kg oral dose of AZD8330 inhibits ERK phosphorylation by > 90% for between 4 and 8 hours. Doses as low as 0.4 mg/kg once daily are sufficient for > 80% tumor growth inhibition in the Calu-6 nude rat xenograft model. In the Calu-6 model, AZD8330 inhibits tumor growth in a dose-dependent fashion, at 0.3 mg/kg and 1.0 mg/kg once daily. |
MEK1 enzymatic assays:NH2-terminal hexahistidine tagged, constitutively active MEK1 (S218D, S222D ΔR4F) is expressed in baculovirus-infected Hi5 insect cells and purified by immobilized metal affinity chromatography, ion exchange, and gel filtration. The activity of MEK1 is assessed by measuring the incorporation of [γ- 33P]phosphate from [γ-33P]ATP onto ERK2. The assay is carried out in a 96-well polypropylene plate with an incubation mixture (100 μL) composed of 25 mM HEPES (pH 7.4), 10 mM MgCl2, 5 mM β-glycerolphosphate, 100 μM sodium orthovanadate, 5 mM DTT, 5 nM MEK1, 1 μM ERK2, and 0 to 80 nM AZD8330 (final concentration of 1% DMSO). The reactions are initiated by the addition of 10 μM ATP (with 0.5 μC k[γ-33P]ATP/well) and incubated at room temperature for 45 min. An equal volume of 25% trichloracetic acid is added to stop the reaction and precipitate the proteins. Precipitated proteins are trapped onto glass fiber B filter plates, excess labeled ATP is washed off with 0.5% phosphoric acid, and radioactivity is counted in a liquid scintillation counter. ATP dependence is determined by varying the amount of ATP in the reaction mixture. The data are globally fitted.

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.
