2 Customer Reviews
The compounds BAY80-6946 and TG100713, which are respectively an alpha/beta- and a pan-isoforms inhibitors, demonstrated a very good ability to block Jurkat E6.1 proliferation with an IC50 slightly higher than 1 mM.

|Description||BAY 80-6946 (Copanlisib) is a potent pan-class I PI3K with IC50 of 0.5, 3.7, 6.4, and 0.7 nM in cell-free assays for PI3Kα/β/γ/δ , respectively. Phase 3.|
In both KPL4 cells and LPA-stimulated PC3 cells, BAY 80-6946 reduces pAKT levels. In a subset of human cancer cell lines with PIK3CA mutations and/or overexpression of HER2, BAY 80-6946 shows antiproliferative activity and induces apoptosis.  The combination of HER2-targeted therapies and BAY 80-6946 inhibits growth more effectively than either therapy used alone, and can restore sensitivity to trastuzumab and lapatinib in cells. 
|In vivo||In rat KPL4 or HCT116 tumor xenograft model, BAY 80-6946 (6 mg/kg, i.v.) induces 100% complete tumor regression. In nude mice with Lu7860 erlotinib-resistant, patient-derived NSCLC and MAXF1398 patient-derived luminal breast tumor models, BAY 80-6946 (14 mg/kg, i.v.) also causes tumor growth inhibition. |
Biochemical lipid kinase assays:The effect of BAY 80-6946 on PI3Kα, PI3Kβ, and PI3Kγ activity is measured by the inhibition of 33P incorporation into phosphatidylinositol (PI) in 384-well MaxiSorp® plates coated with 2 µg/well of PI and phosphatidylserine (PS) (1:1 molar ratio). In each PI3K isoform assay, 9 µL of reaction buffer (50 mM MOPSO, pH 7.0, 100 mM NaCl, 4 mM MgCl2, 0.1% BSA) containing 7.5 ng of His-tagged N-terminal truncated p110α or p110β protein, or 25 ng of purified human p110γ protein, is used. The reaction is started by adding 5 µL of a 40-µM ATP solution containing 20 µCi/mL [33>/sup>P]-ATP. After 2 hours incubation at room temperature, the reaction is terminated by addition of 5 µL of a 25-mM EDTA solution. The plates are washed and Ultima Gold™ scintillation cocktail (25 µL) is then added. The radioactivity incorporated into the immobilized PI substrate is determined with a BetaPlate Liquid Scintillation Counter.

* 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.
