1 Customer Review
The established (SQ20B/UMSCC47/SCC90 cells) or primary (“P1/P2/P3”) human NSCC cells as well as normal oral epithelial cells (“Epithelial cells”) were treated with indicated concentration of GDC-0349, rapamycin (“Rap”) or RAD001 for applied time, cell proliferation was tested by CCK-8 assay. Expression of listed proteins in primary human NSCC cells was tested by Western blot analysis (D, right panel). “UNTR” indicates untreated control cells. * p < 0.05 vs. “UNTR” cells. # p < 0.05 vs. GDC-0349-only cells.

|Description||GDC-0349 is a potent and selective ATP-competitive inhibitor of mTOR with Ki of 3.8 nM, 790-fold inhibitory effect against PI3Kα and other 266 kinases. Phase 1.|
GDC-0349 has remarkable selectivity over 266 kinases, including all isoforms of PI3K. GDC-0349 inhibits downstream markers of mTOR, including phospho-4EBP1 and phospho-Akt(S473) in an in vivo PK/PD study in mouse, consistent with an inhibition of both mTORC1 and mTORC2 complexes. 
|In vivo||GDC-0349 demonstrates pathway modulation and dose-dependent efficacy in mouse xenograft cancer models. When dosed orally once daily in athymic mice in a MCF7-neo/Her2 tumor xenograft model (PI3K mutation), GDC-0349 inhibits tumor growth in a dose-dependent manner. It is also efficacious in other xenograft models, including PC3 (PTEN null) and 786-O (VHL mutant). |

* 1 mg/ml means slightly soluble or insoluble.
* 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.
