Antitumor agent-28 is a compound that specifically targets and inhibits the activity of the ataxia telangiectasia mutated (ATM) kinase. By doing so, it effectively impedes the progression of ATM-mediated diseases and demonstrates significant anti-cancer activity.
ATR-IN-4, a potent inhibitor of ATR (Ataxia telangiectasia mutated gene Rad 3-associated kinase), restricts the growth of DU145 prostate cancer cells and NCI-H460 lung cancer cells, with IC 50 values of 130.9 nM and 41.33 nM, respectively.
