VE-821 shows excellent selectivity for ATR with minimal cross-reactivity against the related PIKKs ATM, DNA-PK, mTOR and PI3K (Kis of 16 μM, 2.2 μM, >1 μM and 3.9 μM, respectively. VE-821 alone commits a large fraction of cancer cell populations to death, but it only reversibly limits cell cycle progression in normal cells, with minimal death or long-term detrimental effects. VE-821 along with cisplatin treatment shows the most marked synergy. [1] VE-821 inhibits H2AX cell growth with IC50 of 800 nM. [2] |

Protocol
| Kinase Assay: |
- Collapse
Kinase inhibition: The ability of compounds to inhibit ATR, ATM or DNAPK kinase activity istested using a radiometric-phosphate incorporation assay. A stock solution isprepared consisting of the appropriate buffer, kinase, and target peptide. To this isadded the compound of interest, at varying concentrations in DMSO to a final DMSO concentration of 7%. Assays are initiated by addition of an appropriate [γ-33P]ATP solution and incubated at 25 ℃. Assays are stopped, after the desired time course, by addition of phosphoric acid and ATP to a final concentration of 100 mM and 0.66μM, respectively. Peptides are captured on a phosphocellulose membrane, prepared as per manufacturer |

Bio Calculators
Molarity Calculator
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 SDS / COA (available on product pages).
Dilution Calculator
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 SDS / 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.
