Application

VE-821 has been used as an inhibitor of ATM- and Rad3-related (ATR) protein in human cancer cells.

Biochem/physiol Actions

VE-821 is a potent ATP-competitive inhibitor of the DNA damage response (DDR) kinase Ataxia telangiectasia-mutated (ATM) and ATM- and Rad3-related (ATR) with a Ki of 13 nM. VE-821 has minimal cross-reactivity against the related PIKKs ATM, DNA-dependent protein kinase (DNA-PK), mTOR and PI3-kinase-γ (Ki of 16 μM, 2.2 μM, >1 μM and 3.9 μM, respectively) and against a large panel of unrelated protein kinases. VE-821 used alone caused death in a large fraction of cancer cell populations and also showed strong synergy with genotoxic agents. VE-821 increased sensitivity of cells to radiation and also sensitized cancer cells to a variety of chemotherapeutic agents.

Other Notes

VE-821 has been expertly reviewed and recommended by the Chemical Probes Portal. For more information, please visit the VE-821 probe summary on the Chemical Probes Portal website.

Protection of telomere 1 (POT1), the telomeric single-stranded DNA (ssDNA)-binding protein in the shelterin complex, has been implicated in the DNA damage response, tumorigenesis and aging. Telomere dysfunction induced by telomere deprotection could accelerate cellular senescence in primary human cells.
