|Description||Copanlisib (BAY 80-6946) 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.

2.Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such as vortex, ultrasound or hot water bath can be used to aid dissolving.
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.
