K562 and K562R cells were pre-treated for 1 h with CGK733 (5 μM), then treated with CTD (10 μM) for 24 h, and protein levels of cleaved PARP, Mcl-1, and phosphorylated H3 were determined by Western blotting. GAPDH served as a normal control.

|Description||CGK 733 is a potent and selective inhibitor of ATM/ATR with IC50 of ~200 nM.|
CGK733 is able to confer robust growth to senescent cells that have ceased proliferation. Senescence-associated β-galactosidase (SA–β-gal) activity disappears in CGK733-treated cells. CGK733 shows greater potency in inhibiting ATM/ATR than LY294002 (IC50 , ~5 μM for ATM and ATR), a pan-inhibitor of PI3K and PIKKs.  CGK733 (30 μM) treated for 24h causes ~60% cell death in senescent MCF-7 cells.  CGK733 (20 μM) induces the loss of cyclin D1 via the ubiquitin- dependent proteasomal degradation pathway in MCF-7 and T47D breast cancer cell lines. CGK733 at concentrations ranging from 0.6- 40 μM, inhibits proliferation of MCF-7 and T47D estrogen receptor (ER) positive breast cancer cells, MDA-MB436 ER negative breast cancer cells, LnCap pros-tate cancer cells and HCT116 colon cancer cells. Furthermore, CGK733 also suppresses proliferation of non- transformed mouse BALB/c 3T3 embryonic fibroblast cells. The CGK733-mediated inhibition of proliferation is dose dependent and significant at doses as low as 2.5 μM.

* 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.
