Biological Activity

Description ETP-46464 is a potent and selective inhibitor of ATR with IC50 of 25 nM.
Targets
mTOR [1] ATR [1] DNA-PK [1] PI3Kα [1] ATM [1]
0.6 nM 14 nM 36 nM 170 nM 545 nM
In vitro ETP-46464 shows almost full activity against ATR at 100 nM. ETP-46464 inhibits the activity of PI3Kα, mTOR and DNA-PKcs with IC50s of 170, 0.6 and 36 nM. ETP-46464 is able to promote the breakage of stalled replication forks. Exposure to ETP-46464 leads the generation of substantial amounts of DNA damage in replicating cells. 1 μM ETP-46464 abrogates the ionizing radiation-induced G2/M checkpoint and leads to the presence of micronuclei or completely fragmented nuclei in cells. ETP-46464 is particularly toxic for p53-deficient cells, which is exacerbated by replicative stress-generating conditions such as the overexpression of cyclin E. [1]
Features Selective ATR inhibitor and particularly toxic to p53-deficient cancer cells. Often used as a pharmacologic probe due to its ideal pharmacological properties.
