The cells were treated with either brusatol (40 nM) or mubritinib (8 nM) alone and in combination for 2 h followed by treatment with increasing concentrations of oxaliplatin for 72 h. The differential impacts of Nrf2 and Her2 inhibition (A and B) in the survival rate of SW480/Res cells have been shown.

|Description||Mubritinib (TAK-165) is a potent inhibitor of HER2/ErbB2 with IC50 of 6 nM in BT-474 cell; no activity to EGFR, FGFR, PDGFR, JAK1, Src and Blk in BT-474 cell line. Phase 1.|
Mubritinib displays > 4000-fold selectivity over other tyrosine kinases, such as EGFR, FGFR, PDGFR, Jak1, Src and Blk. Mubritinib even at low concentration of 0.1 μM significantly blocks HER2 phosphorylation, leading to the downregulation of PI3K-Akt and MAPK pathway in cell line BT474 with high level of HER2. Mubritinib not only exhibits highly potent antiproliferative effect in ErbB2-overexpressing cancer cell line BT474 with an IC50 of 5 nM, but also displays marked antiproliferative effects in cell lines with HER2 expressed weakly with IC50 of 53 nM, 90 nM and 91 nM for LNCaP, LN-REC4 and T24, respectively. Mubritinib displays no inhibitory activities against PC-3 cells with HER2 expressed very faintly with IC50 of 4.62 μM, as well as EGFR-overexpressing HT1376 and ACHN cell lines with IC50 of >25 μM. 
|In vivo||Mubritinib significantly inhibits LN-REC4 xenograft with treatment/control tumor volume ratio of 26.5%. Although ineffective to inhibit the growth of UMUC-3 and ACHN cells in vitro (IC50s of 1.812 and >25 μM, respectively), oral administration of Mubritinib (10 or 20 mg/kg per day) significantly inhibits the growth of UMUC-3 and ACHN xenografts with treatment/control tumor volume ratio of 22.9% and 26%, respectively, as compared with Herceptin (20 mg/kg) which is ineffective to UMUC-3 tumor growth. |
Inhibition of HER2/erbB2 tyrosine kinase activity:BT-474 cells are seeded on 24-well plates and cultured overnight. Mubritinib is then added at various concentrations. After incubation for 2 hours, the cells are harvested directly into sodium dodecyl sulfate (SDS)-sample buffer (200 μL). Aliquots containing equal amounts of total cell extract are run on 7.5% to 15% gradient SDS–polyacrylamide gel electrophoresis (PAGE). Following electrophoresis, proteins are transferred onto a polyvinylidene fluoride (PVDF) membrane, for western blot analysis using a relevant primary antibody. Detection of protein is accomplished by an enhanced chemiluminescent (ECL) detection method. The extent of tyrosine phosphorylation of HER2/erbB2 is measured by the LAS-1000 plus lumino-image analyser. The concentration of Mubritinib that inhibits HER2/erbB2 phosphorylation by 50% (IC50) is calculated from a dose–response curve generated by least-squares linear regression of the response using SAS software.

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.
