Description:

WARNING: This product is for research use only, not for human or veterinary use.

BAY-1125976 is a potent and selective allosteric AKT1/2 inhibitor. BAY-1125976 exhibits high efficacy on AKT signaling-dependent tumor growth in mouse models. BAY 1125976 potently and selectively inhibited the activity of full-length AKT1 and AKT2 by binding into an allosteric binding pocket formed by kinase and PH domain. In vitro, BAY 1125976 inhibited cell proliferation in a broad panel of human cancer cell lines. BAY 1125976 exhibited strong in vivo efficacy in both cell line and patient-derived xenograft models such as the KPL4 breast cancer model (PIK3CAH1074R mutant), the MCF7 and HBCx-2 breast cancer models and the AKTE17K mutant driven prostate cancer (LAPC-4) and anal cancer (AXF 984) models.

More Info
The PI3K-AKT-mTOR signaling cascade is activated in the majority of human cancers, and its activation also plays a key role in resistance to chemo and targeted therapeutics. In particular, in both breast and prostate cancer, increased AKT pathway activity is associated with cancer progression, treatment resistance and poor disease outcome.
Product Data
Biological target:
BAY1125976 is an Akt1/Akt2 inhibitor with IC50 values of 5.2 nM and 18 nM for Akt1 and Akt2, respectively.
In vitro activity:
BAY 1125976 effectively reduced the basal levels of AKT phosphorylation in KPL-4 cells, at both T308 (phosphorylated exclusively by PI3K/PDK1) and S473 (phosphorylated by PI3K/PDK1 and mTORC2) with IC50 values of 0.9 and 1.1 nM, respectively. BAY 1125976 also blocked the activation of a downstream signaling molecule 4EBP1 by phosphorylation at mTOR substrate T70 with an IC50 of 35 nM. To show that BAY 1125976 does not only inhibit the activity of active AKT1 but also the activation of inactive AKT1, its influence on the phosphorylation of T308 by PDK1 was measured in vitro. The incubation of inactive AKT with BAY 1125976 completely inhibited phosphorylation by PDK1.

In vivo activity:
KPL-4 tumor bearing mice were used to investigate the inhibition of tumor growth by treatment with BAY 1125976. Treatment with different doses of BAY 1125976 resulted in potent antitumor efficacy (Figs. 2a and 2b). A clear, statistically significant dose-response was observed after daily oral treatment with 25 or 50 mg/kg BAY 1125976 with T/Cvolume ratios of 0.14 and 0.08, respectively (p < 0.001; Supporting Information Table S1). A once daily oral dose of 10 mg/kg was less efficacious showing higher T/Cvolume ratio of 0.43 (p > 0.05) and progressive disease as the predominant outcome. Daily administration of 25 or 50 mg/kg BAY 1125976 resulted in significant antitumor efficacy in MCF7-implanted nude mice compared with the control with T/Cvolume values of 0.25 and 0.25 (p < 0.001) and T/Cweight values of 0.33 and 0.37 (p < 0.001 and p = 0.0016), respectively (Figs. 2c and 2d and Supporting Information Table S1).
