General description
A cell-permeable pyrido-pyrimidine compound that acts as a highly selective and potent inhibitor against both mTORC1 & mTORC2 (IC50 = ~10 nM against mTOR activity in raptor or rictor immunoprecipitate from HEK293 with 100 µM ATP), with much reduced potency against MKK1 and PI 3-Kα (IC50 ~9 µM) and little or no activity toward more than 200 other protein and lipid kinases, including Akt, ATR, DNA-PK, PDK1, and PI 3-Kβ/γ/δ. Shown to effectively inhibit cellular mTOR phosphorylation on Ser2448/2481 as well as the phosphorylation and activation of mTORC1/2 downstream effector molecules such as Akt, S6K, 4E-BP1, but not RSK or Erk1/2, kinases that are not regulated by mTOR. Although Ku-63794 is shown not to affect IGF-1-induced Akt phosphorylation on Ser308 by PDK1 in mTORC2 knockout MEF cultures, Ku-63794 treatment of mTORC2-expressing MEF cells is shown to inhibit IGF-1-induced Akt Ser308 phosphorylation.
