Number of γH2AX foci per cell of irradiated (2 Gy) SAS cells treated with inhibitors against ATM (ATMi, KU55933), DNA-PK (DNA-PKi, KU57788), or ATR (ATRi, AZD6738) with or without LY364947.

AZD6738 (AZD) synergizes with cytarabine (ara-C) to induce apoptosis and proliferation inhibition in AML cells. (a) OCI-AML3 cells were treated with cytarabine and AZD6738, alone or in combination, for 24 h and then subjected to annexin V-FITC/PI staining and flow cytometry analyses. CI values were calculated using CompuSyn software. Combined drug treatments were compared to single drug treatment using 1-way ANOVA with Bonferroni post hoc test. ***indicates p < 0.001. (b and c) OCI-AML3 cells were treated with cytarabine and AZD-6738, alone or in combination, for 24 h. Whole cell lysates were subjected to Western blotting and probed with the indicated antibodies.

MyLa2000 cells were irradiated with UVA at dose 1.6 J/cm2. Kinase inhibitors were added at the following concentrations: 10 μM VE-821, 1 μM VE-822, 1.6 μM Chir-124, 1 μM AZD6738, 1 μM MK8776 (selected basing on toxicity studies performed previously; data not shown) 30 minutes before irradiation (30 min before UVA), immediately before irradiation (0 min before UVA) or immediately after irradiation (0 min after UVA). Cell viability was analyzed 48 hours after treatment by PI exclusion assay.

|Description||AZD6738 is an orally active, and selective ATR kinase inhibitor with IC50 of 1 nM. Phase 1/2.|
In four Kras mutant cell lines: H23, H460, A549, and H358, AZD6738 inhibits ATR kinase activity and impairs cell viability. In ATM-deficient H23 cells, AZD6738 strongly synergizes with cisplatin to induce rapid cell death.  In p53 or ATM defective cells, AZD6738 treatment results in replication fork stalls and accumulation of unrepaired DNA damage, resulting in cell death by mitotic catastrophe. 
|In vivo||In nude mice bearing H460 and H23 tumors, AZD6738 (50 mg/kg, p.o.) results in tumor growth inhibition (TGI), and the the combination with cisplatin causes rapid regression of ATM-deficient H23 tumors.  In nude mice bearing LoVo xenografts, a combination of AZD6738 (50 mg/kg) + IR (2 Gy) avoids toxicity while still maintaining efficacy. |

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.
