Bioactivity Comments
CP466722-induced disruption of ATM inhibits ATM-dependent phosphorylation events which results in cell cycle checkpoint defects. ATM inhibition has a radiosensitization effect in vitro [1]. CP466722 does not inhibit PI3K or closely related PI3K-like protein kinases (PIKKs), but inhibitory activities against Abl and Src kinases suggest these may be off-targets.
