AN3CA (B), JHUEM2 (D), and MFE296 (H) cells were treated with the indicated doses of BGJ398 and BYL719 alone or in combination for 96 hours, and an SRB assay was subsequently performed.

A549 cell was trypsinized and plated at 50% confluence in DMEM. 16 hours later, BYL719 was added at final concentrations of 0, 1, 5, 10 and 20uM. Another 24 hours later, cells were harvested in RIPA with protease and phosphatase inhibitor cocktail. Total protein concentration was measured by BCA method. Lysates equivalent to 20ug total protein were subject to Western Blot, using total- AKT, pS473-AKT, pT286-CyclinD1 and beta-actin (internal control) antibodies.

|Description||Alpelisib (BYL719) is a potent and selective PI3Kα inhibitor with IC50 of 5 nM in a cell-free assay, and minimal effect on PI3Kβ/γ/δ. Phase 2.|
BYL719 inhibits the proliferation of breast cancer cell lines harboring PIK3CA mutations, correlating with inhibition of various downstream signaling components of the PI3K/Akt pathway. 
|In vivo||BYL719(>270 mg/d) shows statistically significant dose-dependent anti-tumor efficacy in PIK3CA mutant xenograft models in rodents. BYL719 has a low clearance, a half-life of 8.5 h and its exposure increases dose proportionally between 30mg/d and 450mg/d, displaying a low inter-individual variability in Cmax and AUC in human. BYL719(270mg/d) shows first signs of clinical efficacy include 1 confirmed partial response in a patient with ER+ breast cancer, and significant PET responses (PMR) and/or tumor shrinkage are achieved in 8 out of 17 evaluated patients. |
|In vitro||DMSO||88 mg/mL (199.33 mM)|
|Ethanol||2 mg/mL (4.53 mM)|
|In vivo||Add solvents to the product individually and in order(Data is from Selleck tests instead of citations):
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.
