In vitro

In both KPL4 cells and LPA-stimulated PC3 cells, BAY 80-6946 reduces pAKT levels. In a subset of human cancer cell lines with PIK3CA mutations and/or overexpression of HER2, BAY 80-6946 shows antiproliferative activity and induces apoptosis. [1] The combination of HER2-targeted therapies and BAY 80-6946 inhibits growth more effectively than either therapy used alone, and can restore sensitivity to trastuzumab and lapatinib in cells. [2]

BT-474 cells were treated with DMSO, MK2206 (2μM), or BAY 80-6946 (50nM) and viable cells were counted at indicated times, demonstrating loss in viable cell number with PI3K inhibition. Results were reported as a mean of triplicate with standard errors.

In vivo In rat KPL4 or HCT116 tumor xenograft model, BAY 80-6946 (6 mg/kg, i.v.) induces 100% complete tumor regression. In nude mice with Lu7860 erlotinib-resistant, patient-derived NSCLC and MAXF1398 patient-derived luminal breast tumor models, BAY 80-6946 (14 mg/kg, i.v.) also causes tumor growth inhibition. [1]

Biochemical lipid kinase assays:

The effect of BAY 80-6946 on PI3Kα, PI3Kβ, and PI3Kγ activity is measured by the inhibition of 33P incorporation into phosphatidylinositol (PI) in 384-well MaxiSorp® plates coated with 2 µg/well of PI and phosphatidylserine (PS) (1:1 molar ratio). In each PI3K isoform assay, 9 µL of reaction buffer (50 mM MOPSO, pH 7.0, 100 mM NaCl, 4 mM MgCl2, 0.1% BSA) containing 7.5 ng of His-tagged N-terminal truncated p110α or p110β protein, or 25 ng of purified human p110γ protein, is used. The reaction is started by adding 5 µL of a 40-µM ATP solution containing 20 µCi/mL [33>/sup>P]-ATP. After 2 hours incubation at room temperature, the reaction is terminated by addition of 5 µL of a 25-mM EDTA solution. The plates are washed and Ultima Gold™ scintillation cocktail (25 µL) is then added. The radioactivity incorporated into the immobilized PI substrate is determined with a BetaPlate Liquid Scintillation Counter.

  • Cell lines: A series of cancer cell lines
  • Concentrations: ~5 μM
  • Incubation Time: 72 hours
  • Method: Cell proliferation over a 72-hour period is determined using the CellTiter-Glo® luminescent cell viability kit. Briefly, cells are plated in separate microtiter plates. Following an overnight incubation at 37ºC, luminescence values in the t=0 hour plates are determined. Test compounds diluted in growth medium are added to the t=72 hour plates, and the cells are then incubated for 72 hours at 37ºC. Luminescence values are determined with a Wallac 1420 Victor2™ 1420 multilabel HTS counter after a 10-minute reaction with CellTiter-Glo® solution. The percentage inhibition of cell growth is calculated by subtracting the luminescence values in the t=0 hour plates from the corresponding values in the t=72 hour plates. Differences in values between drug-treated cells and controls are used to determine the percentage inhibition of cell growth.
