製品説明 VE-821(ATR inhibitor IV) 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
In vitro

VE-821(ATR inhibitor IV) 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.  [1]

VE-821(ATR inhibitor IV) inhibits H2AX cell growth with IC50 of 800 nM. [2]

Kinase Assay 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

実験の流れ

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.
