Safety
For Research Use Only. Not for use in diagnostic or therapeutic procedures, and not for human or veterinary use. Handle in accordance with your institution's chemical hygiene plan.
In Vitro
ATR-IN-23 has significant inhibitory potency against ATR (IC50 = 1.5 nM) and strong antiproliferative activity against LoVo cells (IC50 = 0.073 μM)[1]. Against HT-29 cells, ATR-IN-23 shows moderate antiproliferative potency (IC50 = 0.161 μM)[1].
In Vivo
ATR-IN-23 causes acute toxicity at a maximum concentration of 2000 mg/kg and has moderate safety in ICR mice[1]. In BALB/c nude mice, ATR-IN-23 (50 mg/kg; once or twice daily; p.o.; 21 days) shows moderate antitumor efficacy[1].
