Biological Activity

KU-0063794 is a potent and selective mTOR inhibitor with IC50 values of approximately 10 nM for mTORC1 and mTORC2.But KU-0063794 does not inhibit the activity of 76 other protein kinases and seven lipid kinases at 1000-fold higher concentrations. KU-0063794 also inhibited growth of T47D breast cancer cells with a GI50 of 0.35 µM.

Cell Experiment
Cell lines MEFs cell line
Preparation method Cell growth. MEFs were seeded in 24-well plates (20000 cells per 1.91 cm2 well) and grown overnight in the presence of 10% foetal bovine serum. Cells were then treated in the presence or absence or rapamycin or Ku-0063794 and the medium was changed every 24 h with freshly dissolved inhibitors. Every 24 h of treatment, cells were washed once with PBS, and fixed in 4% (v/v) paraformaldehyde in PBS for 15 min. After washing once with water, the cells were stained with 0.1% Crystal Violet in 10% ethanol for 20 min and washed three times with water. Crystal Violet was extracted from cells with 0.5 ml of 10% (v/v) ethanoic (acetic) acid for 20 min. The eluate was then diluted 1:10 in water, and absorbance at 590 nm was quantified.

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.
