BAY 1125976 inhibits activation of AKT in cell lines carrying the AKT-activating mutation E17K. In KU-19-19 bladder cancer cells activation by phosphorylation is inhibited at AKT1-S473 and 4EBPI-T70 with IC50 values of 35 and 100 nM, respectively. In the prostate cancer cell line LAPC-4, the phosphorylation of AKT1-S473, T308 and 4EBP1-T70 is inhibited with IC50 values of 0.8, 5.6 and 35 nM, respectively. Treatment of LAPC-4 cells with BAY 1125976 results in an inhibition of PRAS40 phosphorylation at T246 as a direct target of AKT1 activity with an IC50 of ∼141 nM. BAY 1125976 inhibits the proliferation of the breast cancer cell lines BT-474, T47D, MCF7, ZR-75–1, EVSA-T, MDA-MB-453, KPL-4 and BT20 as well as the prostate cancer cell lines LNCaP and LAPC-4 with submicromolar IC50 values. Breast cancer cell lines of luminal type show strong inhibition of cell proliferation following BAY 1125976 treatment..
Treatment with different doses of BAY 1125976 results in potent antitumor efficacy in KPL-4 tumor bearing mice. A clear, statistically significant dose-response is observed after daily oral treatment with 25 or 50 mg/kg BAY 1125976 with T/Cvolume ratios of 0.14 and 0.08, respectively. Daily administration of 25 or 50 mg/kg BAY 1125976 results in significant antitumor efficacy in MCF7-implanted nude mice compared with the control with T/Cvolume values of 0.25 and 0.25 and T/Cweight values of 0.33 and 0.37, respectively. BAY 1125976 displays good antitumor efficacy in vivo in AKT1E17K mutated models..

1.Please make sure the liquid is clear before adding the next solvent.
2.Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such as vortex, ultrasound or hot water bath can be used to aid dissolving.
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.
