ATR inhibitor AZD6738 prevent NCI‐H929 TP53−/− cell growth in NSG mice. NSG mice were subcutaneously injected with 106 NCI‐H929 TP53−/− cells (left panel). After 1 week, mice with detectable tumors were randomly distributed into four groups of seven mice and treated with AZD6738 (25 mg/kg; i.g., 5 times a week for 2 weeks), as indicated by the arrows (middle panel). The graphs represent the tumor volume kinetics (mean±SD, middle panel) and the tumor volume on Day 12 (right panel).
