BEZ235 (NVP-BEZ235) is a potent dual inhibitor of PI3K and mTOR. BEZ235 (NVP-BEZ235) is able to effectively and specifically block the dysfunctional activation of the PI3K pathway and induce G (1) arrest. It also inhibits the growth of human cancer in animal models. For Class I PI3K family, NVP-BEZ235 biochemical IC50 are 4nM against p110α, 75nM against p110β, 7nM against p110σ, 5nM against p110γ.

Cell lines | MKN45, BT474, SNU216 and NCI-N87 cell lines |
Preparation method | Cell viability assay Cells were seeded at a density of 2000 cells per well in a 96-well plate and incubated overnight in complete medium. Cells were treated with either trastuzumab, BEZ235, Everolimus, AZD6244 alone, or trastuzumab combined with BEZ235 or Everolimus or AZD6244. After 72 h of incubation, cell viability was determined using the MTS tetrazolium substrate (CellTiter 96 Aqueous One Solution Cell Proliferation Assay, Promega, Madison, WI, USA) following the manufacturer’s instructions. The absorbance was measured at 490 nm using a spectrophotometer. All experiments were repeated three times with at least triplicate readings for each concentration. |

Animal A (mg/kg) = Animal B (mg/kg) multiplied by | Animal B Km |
Animal A Km |
For example, to modify the dose of Compound A used for a mouse (20 mg/kg) to a dose based on the BSA for a rat, multiply 20 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for Compound A of 10 mg/kg.
