| Synonyms | BAY 80-6946 2HCl; BAY806946 dihydrochloride; BAY80-6946; BAY-80-6946; BAY-806946; BAY 806946 dihydrochloride |
| In Vitro | 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. 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. Kinase Assay: 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(R) 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(TM) scintillation cocktail (25 μL) is then added. The radioactivity incorporated into the immobilized PI substrate is determined with a BetaPlate Liquid Scintillation Counter. Cell Assay: Cell proliferation over a 72-hour period is determined using the CellTiter-Glo(R) 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(TM) 1420 multilabel HTS counter after a 10-minute reaction with CellTiter-Glo(R) 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. |

| 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. |
| Animal model | Rats bearing KPL4 or HCT116 xenografts |
