Fig 1. CC-223 is cytotoxic and anti-proliferative to cultured human HCC cells. Cultured HCC cell lines (HepG2, KYN-2 and Huh-7 lines), L02 normal hepatocytes as well as the primary human HCC cells ("HCC1/2/3" lines) were either left untreated ("C", same for all figures) or treated with designated concentration of CC-223 (10–1000 nM), cells were further cultivated in conditional medium for indicated time; Cell survival (A, B, C and E), and proliferation (D) were tested by listed assays. Data were expressed as mean ± SD (Same for all figures). n = 5 means five replicate wells (Same for Figs 1–4). * p <0.05 vs. "C".

|Description||CC-223 is a potent, selective, and orally bioavailable mTOR inhibitor with IC50 of 16 nM, >200-fold selectivity over the related PI3K-α. Phase 1/2.|
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. 
|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. |
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.

* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.
Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:
Mass (mg) = Concentration (mM) × Volume (mL) × Molecular Weight (g/mol)
*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and MSDS / COA (available on product pages).
Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:
Concentration (start) x Volume (start) = Concentration (final) x Volume (final)
This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )
* When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and MSDS / COA (available online).

Definitions of molecular mass, molecular weight, molar mass and molar weight:
Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
