|Description||TAK-632 is a potent pan-Raf inhibitor with IC50 of 8.3 nM and 1.4 nM for B-Raf(wt) and C-Raf in cell-free assays, respectively, showing less or no inhibition against other tested kinases.|
|Features||Orally bioavailable, pan-raf inhibitor that targets both wild-type and mutant forms.|
TAK-632 inhibits phosphorylation of MEK and ERK in melanoma A375 cells (BRAFV600E) with IC50 of 12 nM and 16 nM, respectively. In human melanoma HMVII cells (NRASQ61K/BRAFG469V), TAK-632 also shows strong inhibition of pMEK and pERK with IC50 of 49 nM and 50 nM, respectively. Moreover, TAK-632 also exhibits antiproliferative activity in both A375 and HMVII cells with GI50 of 66 nM and 200 nM, respectively.  TAK-632 induces RAF dimerization but inhibits the kinase activity of the RAF dimer because of its slow dissociation from RAF. The combination of TAK-632 and TAK-733 exhibits synergistic antiproliferative effects in BRAF- and NRAS-mutated melanoma cells. 
|In vivo||TAK-632 shows superior oral bioavailability in both rats and dogs. TAK-632 (3.9–24.1 mg/kg, p.o.) exhibits dose-dependent antitumor efficacy without severe body weight reduction in a melanoma A375 (BRAFV600E) xenograft model and a human melanoma HMVII (NRASQ61K/BRAFG469V) xenograft in rats.  In NRAS-mutant melanoma SK-MEL-2 xenograft model, TAK-632 (60 or 120 mg/kg, p.o.) also exhibits potent antitumor efficacy without severe toxicity. |
Kinase Profile Assay:Assays for serine/threonine kinases using radio labeled [γ-33P] ATP are performed in 96 well plates. BRAF and c-RAF are expressed as N-terminal FLAG-tagged protein using a baculovirus expression system. The reaction conditions are optimized for each kinase: BRAF (25 ng/well of enzyme, 1 μg/well of GST-MEK1(K96R), 0.1 μCi/well of [γ-32P] ATP, room temperature, 20 min reaction); c-RAF (25 ng/well of enzyme, 1 μg/well of GST-MEK1 (K96R), 0.1 μCi/well of [γ-32P] ATP, room temperature, 20 min reaction). Enzyme reactions are performed in 25 mM HEPES, pH 7.5, 10 mM magnesium acetate, 1 mM dithiothreitol and 0.5 μM ATP containing optimized concentration of enzyme, substrate and radiolabeled ATP as described above in a total volume of 50 μL. Prior to the kinase reaction, compound and enzyme are incubated for 5 min at reaction temperature as described above. The kinase reactions are initiated by adding ATP. After the reaction period as described above, the reactions are terminated by the addition of 10% (final concentration) trichloroacetic acid. The [γ-33P] or [γ-32P]-phosphorylated proteins are filtered in GFC filter plates with a Cell Harvester and then the plates are washed out with 3% phosphoric acid. The plates are dried, followed by the addition of 40 μL of MicroScint0. The radioactivity is counted by a TopCount scintillation counter.

Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:
Mass (mg) = Concentration (mM) × Volume (mL) × 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.
