VE-821 is an inhibitor of ataxia telangiectasia and Rad3-related (ATR) kinase, a chromatin-remodeling protein that senses DNA damage and activates the DNA damage checkpoint to induce cell cycle arrest. VE-821 exhibits anticancer activity, inducing chromosome fragmentation, apoptosis, and cell death in vitro. VE-821 decreases phosphorylation of Chk1 and induces G2 phase cell cycle arrest in pancreatic cancer cells and leukemia cells, sensitizing them to the effects of radiation.
