Biochem/physiol Actions
Potent and selective DNA-dependent protein kinase (DNA-PK) inhibitor in vitro and in vivo.
NU7441 is a potent and selective DNA-dependent protein kinase inhibitor (DNA-PK IC50 = 14 nM; IC50 = 1.7 μM/mTOR, 5 μM/PI3Kα, >100 μM/ATM & ATR) that effectively sensitizes cancer cells to the cytotoxic effects of both ionizing radiation and the topoisomerase II inhibitor etoposide in cultures (0.5 μM; SW620 & LoVo cells) and in vivo (10 mg/kg via daily i.p. in mice with human colon cancer SW620 xenografts).
