The TMZ/XL765 combination decreases serum GH and PRL of mice bearing GH3 xenografts. A and B, After treatment with DMSO, TMZ, XL765, or the XL765/TMZ combination, the blood of the nude mice xenograft with GH3 tumor was collected and serum rat-GH and rat-PRL were measured by IRMA (TMZ/XL765 combination vs TMZ or XL765 alone: ***P <.001).

TMZ, XL765, or the TMZ/XL765 combination treatment inhibits the cell proliferation and induces the cell apoptosis of GH3 cells in vivo. A and B, Ki-67 expression in the section of GH3 tumors treated with DMSO, TMZ, XL765, or the TMZ/XL765 combination was determined by IHC. Positive cells appear brown, whereas negative cells remain blue (n=10 tumors per group). Magnification, ?0 as indicated. CTRL, control. C and D , The apoptotic cells of tumor tissues from various treatments were detected by TUNEL staining. TUNEL-positive cells appear brown, whereas negative cells remain blue (n =10 tumors per group). Magnification, ?40 as indicated. (TMZ/XL765 combination vs TMZ or XL765 alone; *** P<0.001).

In vitro |
XL765 is active against class I PI3K (IC50 = 39, 113, 9 and 43 nM for p110α, β, γ and δ, respectively). XL765 also inhibits DNA-PK (IC50 = 150 nM) and mTOR (IC50 = 157 nM) but not XL-147 which shows IC50 values of > 15 μM. [1] XL765 treatment results in decreased cell viability in 13 PDA cell lines in a dose-dependent manner. XL765, a dual-target PI3K/mTOR inhibitor, inhibits cell growth and apoptosis in many more cell lines and at lower concentrations as compared to the PI3K-selective inhibitors XL147 and PIK90. The effect can be recapitulated by using combinations of single-targeted compounds. XL765 significantly reduces phosphorylation of the mTOR targets S6, S6K, and 4EBP1, which is associated with greater apoptosis induction rather than to PI3K inhibition alone. XL765 treatment causes accumulation of autophagosomes in MIAPaCa-2 cells, and results in significant dose-dependent AVO induction and LC3-II stimulation in MIAPaCa-2 cells stably expressing a LC3-GFP construct.

In vivo | The combination of XL765 (30 mg/kg) with chloroquine (50 mg/kg) results in significant inhibition of BxPC-3 xenograft growth in mice models, while XL765 alone at the same dose has no inhibitory effect. [2] Oral administration of XL765 results in greater than 12-fold reduction in median tumor bioluminescence compared to control and improvement in median survival in nude mice implanted intracranially with GBM 39-luc cells. XL765 in combination with temozolomide (TMZ) yields a 140-fold reduction in median bioluminescence with a trend toward improvement in median survival compared with TMZ alone. [3] |

Bio Calculators
Molarity Calculator
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).
Dilution Calculator
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.
