Hep-2 (D) or SCC-9 (E) cells were treated with PI3K/Akt and mTOR dual inhibitor LY 294002 (LY, 1 umol/L), mTORC1 inhibitor rapamycin (0.5 umol/L), mTORC1/2 dual inhibitor AZD2014 (0.1 uM), INK-128 (0.1 uM) or AZD8055 (0.1 uM) for 72 h, cell viability was analyzed. The mean of three independent experiments performed in triplicate was shown. Statistical significance was analyzed by ANOVA. *p < 0.01 vs Control. **p < 0.01 vs. AZD8055 group.

|Description||Sapanisertib (INK 128, MLN0128) is a potent and selective mTOR inhibitor with IC50 of 1 nM in cell-free assays; >200-fold less potent to class I PI3K isoforms, superior in blocking mTORC1/2 and sensitive to pro-invasion genes (vs Rapamycin). Phase 1.|
INK 128 exhibits an enzymatic inhibition activity against mTOR and more than 100-fold selectivity to PI3K kinases.  As TORC1/2 inhibitor, INK 128 inhibits both the phosphorylation of S6 and 4EBP1, the downstream substrates of TORC1, and selectively inhibits AKT phosphorylation at Ser473, the downstream substrate of TORC2. Furthermore, INK 128 also shows potent inhibition effects on cell lines resistant to rapamycin and pan-PI3K inhibitors. 
|In vivo||In a ZR-75-1 breast cancer xenograft model, INK 128 shows tumor growth inhibition efficacy at a dose of 0.3 mg/kg/day.  Daily, oral administration of INK 128 inhibits angiogenesis and tumor growth in multiplexenograft models. |
|In vitro||DMSO||62 mg/mL (200.43 mM)|
|Ethanol||2 mg/mL (6.46 mM)|
|In vivo||Add solvents to the product individually and in order:
30% PEG400+0.5% Tween80+5% propylene glycol
For best results, use promptly after mixing.
* 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 (g) = Concentration (mol/L) × Volume (L) × 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.
