Bioactivity Comments
RP-3500 is selective for ATR and it inhibits ATR kinase activity in biochemical and cell-based assays. It exhibits 30-fold selectivity over mammalian target of rapamycin (mTOR) and >2,000-fold selectivity over ataxia telangiectasia mutated (ATM) kinase, DNA-dependent protein kinase (DNA-PK), and phosphatidylinositol 3-kinase alpha (PI3Kα) in vitro [1].
