VE-821

Ataxia-telangiectasia and Rad3-related protein (ATR) is a serine/threonine kinase that activates DNA processes related to the DNA damage response. VE-821 is an ATP-competitive inhibitor of ATR (IC50 = 26 nM). It augments DNA damage and cell death of cancer cells in response to radiation under normal and hypoxic conditions. VE-821 also sensitizes cancer cells to chemotherapy.Formal Name: 3-amino-6-[4-(methylsulfonyl)phenyl]-N-phenyl-2-pyrazinecarboxamide. CAS Number: 1232410-49-9. Synonyms: ATR Inhibitor IV.
