|Description||MLN2480 is an oral, selective pan-Raf kinase inhibitor in chinical trials.|
MLN2480 inhibits MAPK pathway signaling in BRAF mutant and some RAS mutant preclinical cancer models at concentrations that are tolerated in vivo. It is found to activate phosphorylated MEK at very low concentrations, but inhibits this same activity at higher concentrations. The inhibitory effects of MLN-2480 are found to vary across models and genetic contexts. In vitro analysis of this drug combination of MLN2480 and TAK-733(an investigational allosteric MEK kinase inhibitor) in cell proliferation assays demonstrates synergistic activity .In addition, western blot analysis demonstrates the effect of MLN2480 in reversing feedback activation of MEK in response to TAK-733, leading to more concerted MAPK pathway inhibition.MLN-2480 only modestly inhibits PRAK.
|In vivo||In vivo, MLN2480 shows antitumor activity in melanoma, colon, lung, and pancreatic cancer xenograft models.MLN-2480 (37.5 mg/kg) is well tolerated in a tumor xenograft model. The combination of MLN-2480 (12.5 mg) and TAK-733 (1 mg/kg) is effective in an SK-MEL-30 xenograft model, but monotherapy with either compound produces negligible effects.|

* 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.
