| In vitro |
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. [1] AZD6244 is sensitive to Raf mutations in breast cancer cell lines and Ras mutations in NSCLC cell lines. [2] |

| 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. [1] 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. [3] 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.

Protocol
| Kinase Assay: |
+ Expand
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. |

Bio Calculators
Molarity Calculator
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).
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 )
* 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.
