BAY1125976

BAY 1125976 is a selective allosteric AKT1/2 inhibitor,exhibits high efficacy on AKT signaling-dependent tumor growth in mouse models. BAY1125976 inhibits the activity of AKT1 (IC50 = 5.2 nM at 10 µM ATP and 44 nM at 2 mM ATP) and AKT2 (IC50 = 18 nM at 10 µM ATP and 36 nM at 2 mM ATP) very potently.Whereas BAY1125976 is almost inactive on AKT3 (IC50 = 427 nM at 10 µM ATP).

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.[1].

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].

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 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.
