Biological Activity

Description VE-821 is a potent and selective ATP competitive inhibitor of ATR with Ki/IC50 of 13 nM/26 nM in cell-free assays, shows inhibition of H2AX phosphorylation, minimal activity against PIKKs ATM, DNA-PK, mTOR and PI3Kγ.
Targets
ATR [1]
(Cell-free assay)
13 nM(Ki)
In vitro

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:

[2]

- 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
Cell Research:

[2]

- Collapse
  • Cell lines: H2AX cells
  • Concentrations: --
  • Incubation Time: 96 hours
  • Method:

    Cells are plated in 96-well plates and allowed to adhere overnight. The following day, compounds are added at the indicated concentrations in a final volume of 200μL, and the cells are then incubated for 96 h. MTS reagent (40μL) isthen added, and 1 h later, absorbance at 490 nm ismeasured using a SpectraMax Plus 384 plate reader. Synergy and antagonism are assessed using Macsynergy software.

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.
