Biological Activity for NU 7441

NU 7441 is a potent and selective DNA-PK inhibitor (IC₅₀ = 14 nM). Selective for DNA-PK over a range of kinases including mTOR, PI 3-K, ATM and ATR. Potentiates the effects of doxorubicin (Cat. No. 2252) and etoposide (Cat. No. 1226) in vitro and etoposide in vivo. Also enhances CRISPR-Cas9-mediated homology-directed repair (HDR) efficiency 2 to 3-fold, and decreases nonhomologous end-joining (NHEJ) frequency ~40%.
