a-c, Inhibitors of BRAFV600E (PLX4032) and MEK1/2 (PD98059 or AZD6244) increase PGC1α and ID2 expression (a, b) and repress integrin expression and signalling (b, c). Cells were treated with indicated concentration of inhibitors for 6 h (a, b) or 24 h (c). d, e, PLX4032 increases the interaction between ID2 and TCF4 (d) and decreases the occupancy of TCF4 at the promoters of integrin genes (e). f–g, PGC1α and ID2 are partially required for PLX4032-mediated inhibition of invasion and metastasis. For in vitro assays (f), A375 cells were incubated with 1 μM PLX4032 for 10 h. Images represent one picture captured per membrane with the scale bar representing 200 μm. Values in a, b, e and f represent mean±s.d. of independent biological triplicates; *P<0.05 and **P<0.01 by Student's t-test in a, b, e, f.

|Description||Selumetinib (AZD6244) is a potent, highly selective MEK inhibitor with IC50 of 14 nM for MEK1 and Kd value of 530 nM for MEK2. It also inhibits ERK1/2 phosphorylation with IC50 of 10 nM, no inhibition to p38α, MKK6, EGFR, ErbB2, ERK2, B-Raf, etc. Phase 3.|
|Features||First MEK inhibitor being tested in Phase II clinical trials.|
AZD6244 is not competitive with ATP and inactivates the ERK1/2 phosphorylation with IC50 concentrations below 40 nM. AZD6244 also inhibits the growth of primary HCC cells through inhibition of ERK1/2 and p90RSK phosphorylation, accompanied with elevation of the cleavage of caspase-3 and caspase-7, and cleaved poly(ADP)ribose polymerase. AZD6244 has little effects on the p38, c-Jun-NH2-kinase, phosphatidylinositol 3-kinase, and MEK5/ERK5 pathways.  AZD6244 is sensitive to Raf mutations in breast cancer cell lines and Ras mutations in NSCLC cell lines. 
|In vivo||AZD6244 significantly inhibits phosphorylation of ERK1/2 in 2-1318, 5-1318, 26-1004 and 4-1318 xenografts and induces apoptosis in primary 2-1318 cells by activating the caspase pathway.  AZD6244 could inhibit the tumor growth in HT-29 xenograft, which is a colorectal tumor model carrying a B-Raf mutation, at a dose of 100 mg/kg and the tumor growth inhibition of AZD6244 is better than it of Gemcitabine.  Otherwise AZD6244 could inhibit HCC xenografts tumor growth, which associated with increased apoptosis and down-regulation of cell cycle regulators, including cyclin D1, Cdc-2, CDK2 and 4, cyclin B1, and c-Myc. |
Assay of MEK Kinase Activity:Anti-MEK1 antibody is used to immunoprecipitate MEK1 molecules. MEK kinase activity is measured as the ability of immuno-isolated MEK1 to activate recombinant ERK1 in a coupled assay using MBP as the end point of the assay. Phosphorylated MBP is resolved on a 14% SDS-PAGE gel and vacuum-dried before exposure to X-ray film.

* 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.
