In vitro
In vitro In a panel of cell lines, CC-223 inhibits both mTORC1 (S6RP and 4EBP1) and mTORC2 [AKT(S473)] markers with IC50 ranges of 27 to 184 nM for pS6RP, 120 to 1,050 nM for p4EBP1 and 11 to 150 nM for pAKT(S473), respectively. CC-223 also inhibits cell growth and induces apoptosis across a number of cancer cell lines. [1]
Kinase Assay Kinase assays mTOR.
Reagents are prepared as follows:”Simple Tor buffer”: 10mM Tris pH 7.4, 100mM NaCl, 0.1% Tween-20, 1mM DTT. Recombinant mTOR is diluted in this buffer to an assay concentration of 0.200ug/mL. ATP/Substrate solution: 0.075 mM ATP, 12.5 mM MnCl2, 50 mM Hepes, pH 7.4, 50mM β-GOP, 250 nM Microcystin LR, 0.25 mM EDTA, 5 mM DTT, and 3.5 μg/mL GST-p70S6. Dilution Curve: A 10-point, 1:3 dilution of compounds are prepared in neat DMSO at 50 times the final assay concentration. Detection reagent mix: 50 mM HEPES, pH 7.4 0.01% Triton X-100, 0.01% BSA, 0.1 mM EDTA, 12.7 ug/mL Cy5-anti-GST antibody, 9 ng/ml anti-phospho p70S6 antibody (Thr389), 627ng/mL anti-mouse IgG labeled with Lance Eu. To 20 uL of the Simple Tor buffer is added 0.5 uL of the compound Dilution Curve in DMSO. The final concentration range for compound is 30 to 0.0015 μM. To initiate the reaction, 5 μL of the ATP/substrate solution is added to the above. The reaction is allowed to run for 60 minutes. The assay is stopped by adding 5 μL of 60 mM EDTA. Ten (10) μL of detection reagent mix is then added, and the mixture is allowed to sit at least 2 hours before reading on a Perkin Elmer Envision microplate reader set to detect Europium-based TR-FRET.

Concentrations ~ 10 μM
Incubation Time 72 h
Method Compound is spotted via an acoustic dispenser (EDC ATS-100) into an empty 384-well plate. Cells are diluted to desired densities and added directly to the compound-spotted plates. Cells are allowed to grow for 72 hours. Viability is assessed via Cell Titer-Glo. All data are normalized and represented as a percentage of the DMSO-treated cells. Results are then expressed as GI50 and/or IC50 values.
In Vivo
In vivo In PC-3 tumor-bearing mice, CC-223 (25 mg/kg, p.o.) inhibits both mTORC1 and mTORC2. CC-223 (25 mg/kg, p.o.) also results in tumor growth inhibition by 47% to 95% in xenograft models of prostate, glioma, breast, lung, and colon. [1]
