A-1155463, a highly potent and selective BCL-XL inhibitor, shows picomolar binding affinity to BCL-XL, and >1000-fold weaker binding to BCL-2 and related proteins BCL-W(Ki=19 nM) and MCL-1(Ki>440 nM).

Tumor growth rate (TGR) of tumors orthotopically implanted in rats on day 3, 7 and 10 compared to day 0. Rats were treated with doxorubicin, A-1155463 or a combination. Treatment with A-1155463 resulted in a significant decrease in TGR compared to control mice.
Oncogenesis, 2018, 7(9):74. A-1155463 purchased from Selleck.

|Description||A-1155463, a highly potent and selective BCL-XL inhibitor, shows picomolar binding affinity to BCL-XL, and >1000-fold weaker binding to BCL-2 and related proteins BCL-W(Ki=19 nM) and MCL-1(Ki>440 nM).|
A-1155463 disrupts BCL-XL-BIM but not BCL-2-BIM complexes in cells. A-1155463 kills BCL-XL-dependent Molt-4 cells (EC50=70 nM) but has no measurable cytotoxicity against BCL-2-dependent RS4;11 cells (EC50>5 mM). A-1155463 induces the hallmarks of apoptosis, as evidenced by the release of cytochrome c from mitochondria, caspase activation, and the accumulation of caspase-dependent sub-G0-G1 DNA content in BCL-XL-dependent H146 cells.
|In vivo||Following a single 5 mg/kg IP dose of A-1155463 in nontumor bearing SCID-Beige mice, platelet counts fall dramatically as measured at 6 h postdose and then rebound to normal levels within 72 h. Daily Dosing at 5 mg/kg IP to SCID-Beige mice that had been inoculated with BCL-XL-dependent H146 tumor cells for 14 days causes a statistically significant inhibition of tumor growth (maximum tumor growth inhibition = 44%), which is alleviated upon cessation of dosing.|
|In vitro||DMSO||80 mg/mL (119.44 mM)|
|In vivo||Add solvents to the product individually and in order(Data is from Selleck tests instead of citations):
2% DMSO+30% PEG 300+2% Tween 80+ddH2O
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 (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.
