Ku-0063794 Chemical Structure
BEZ235 (NVP-BEZ235)is a dual ATP-competitive phosphatidylinositol 3-kinase (PI3K) and mammalian target of rapamycin (mTOR) inhibitor of p110α, p110γ, p110δ and p110β with IC50 of 4 nM, 5 nM, 7 nM and 75 nM,respectively.
Deforolimus (Ridaforolimus) is a small-molecule inhibitor of mTOR.
PI-103 is a potent, cell-permeable, ATP-competitive PI3K family member inhibitor with IC50 of 2, 8, 20, 26, 48, 83, 88, 150 nM for DNA-PK, p110α, mTORC1, PI3-KC2β, p110δ, mTORC2, p110β, and p110γ, respectively.
Rapamycin also known as Sirolimus & Rapamune is an mTOR inhibitor. Rapamycin Sirolimus inhibits cell motility by suppression of mTOR-mediated pathways.
Temsirolimus (Torisel) is a mTOR inhibitor.
Everolimus (RAD001) also known as SDZ-RAD, Certican, Zortress and Afinitorm is an mTOR inhibitor available at Selleck with IC50 of 0.63 nM.
WYE-354 is an mTOR inhibitor with an IC50 of 5 nM.
GSK1059615 is a pan-PI3K reversible inhibitor,IC50:PI3Kα(0.4 nM), β (0.6 nM),γ (5 nM),δ (2 nM) and mTOR(12 nM).
XL765 is a mixed mTOR/PI3k inhibitor with IC50 of 157, 39, 113, 9 and 43 nM for mTOR, p110α, β, γ and δ, respectively.
AZD8055 is a potent, selective, and orally bioavailable ATP-competitive mTOR kinase inhibitor with an IC50 of 0.8 nM.
Ku-0063794 is a specific inhibitor of mTOR, which inhibits both mTORC1 and mTORC2 with an IC50 of approximately 10 nM, but does not suppress the activity of 76 other protein kinases or seven lipid kinases, including Class 1 PI3Ks at 1000-fold higher concentrations. Ku-0063794 is cell permeant, suppresses activation and hydrophobic motif phosphorylation of Akt, S6K and SGK. Ku-0063794 also suppressed cell growth and induced a G1-cell-cycle arrest. Ku-0063794 is a prototype of mTOR inhibitor AZD8055 currently in Phase I/II trial in Advance Solid Tumors, Lymphoma and Endometrial Carcinoma. [1]

For MTT assays, cells (2,000 ~ 5,000 cells/well) were subcultured into 96-well plates according to their growth properties. Cell proliferation was assayed at 72 hr after treatment of KU-0063794 by adding 20 μl of 5 mg/ml 3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) solution per 100 μl of growth medium. After incubating for 3-4 h at 37°C, the media were removed and 150 µl/well of MTT solvent (either absolute DMSO or isopropanol containing 4 mM HCl and 0.1% Nonidet-40) was added to dissolve the formazan. The absorbance of each well was measured by ELx808 (BioTek, Winooski, VT) or Wallac Victor2 (Perkin-Elmer Life Sciences, Boston, MA) Microplate Reader. Viable cells are presented as percent of control, vehicle-treated cells.
