ETP-46464 is used as an ATR inhibitor in the treatment of cancer-associated mutations. | [Biological Activity]
etp-46464 is a potent and selective inhibitor for atr (ic50 = 25 nm).atr (atm- and rad3-related) is a member of pikk (phosphatidylinositol 3-kinase-like kinases) that regulates the dna damage response pathways. it is a dna damage sensor that is activated upon genotoxic stresses (e.g. ionizing radiation, uv radiation and dna replication stalling) and phosphorylates its downstream substrates (e.g. p53, brca1 and chek1).etp-46464 abolished the g2/m checkpoint. it caused the presence of micronuclei or completely fragmented nuclei in cells under ionizing radiation. cells treated simultaneously with hydroxyurea and etp-46464 exhibited elevated atm and chk2 phosphorylation. in u2os cells, etp-46464 promoted the breakage of stalked replication forks.
