|Description||BMS-265246 is a potent and selective CDK1/2 inhibitor with IC50 of 6 nM/9 nM in a cell-free assay. It is 25-fold more selective for CDK1/2 than CDK4.|
BMS265246 inhibits the activity of CDK4/cycD with IC50 of 0.23 μM and prevents A2780 Cytox with IC50 of 0.76 μM. BMS265246 which binds to CDK2 shows the inhibitor resides coincident with the ATP purine binding site and forms important H-bonds with Leu83 on the protein backbone. BMS265246 exhibits CDK1 and CDK2 potency that is 25- and 11-fold more potent versus CDK1 and CDK2, respectively. BMS265246 represents the most potent CDK/CDK2 selective analogue from this chemotype.  A recent study shows that BMS-265246 inhibits cell proliferation with EC50 ranging from 0.293 μM-0.492 μM in HCT-116 cells. After treatment of BMS-265246, the dominant cell populations are G2-arrested cells having 4N DNA content, large round nuclei, and low DNA intensity. 
CDK1/Cyclin B1 Kinase Assay:Kinase reactions consists of 100 ng of baculovirus expressed GST-CDK1/cyclin B1 complex, 1 μg histone H1, 0.2 μCi 33P γ-ATP, 25 μM ATP in 50 μL of kinase buffer (50 mM Tris, pH 8.0, 10 mM MgCl2, 1 mM EGTA, 0.5 mM DTT). Reactions are incubated for 45 min at 30 °C and stopped by the addition of cold trichloroacetic acid (TCA) to a final concentration of 15%. TCA precipitates are collected onto GF/C unifilter plates using a Filtermate universal harvester, and the filters are quantitated using a TopCount 96 well liquid scintillation counter. Dose response curves are generated to determine the concentration required to inhibit 50% of kinase activity (IC50). BMS265246 is dissolved at 10 mM in DMSO and evaluated at six concentrations, each in triplicate. The final concentration of DMSO in the assay equals 2%. IC50 values are derived by nonlinear regression analysis and have a coefficient of variance (SD/mean, n = 6) = 16%.

|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 (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.
