Biological Activity

NU 7026 is an ATP-competitive inhibitor of DNA-dependent protein kinase (DNA-PK). Displays selectivity over other PIKK family enzymes (IC50 values are 0.23, 13.0, > 100 and > 100 μM for DNA-PK, PI3K, ATM and ATR respectively). Radiosensitizes both proliferating and quiescent mouse embryonic fibroblast cells to IR and inhibits DSB repair.

I used the DNA-PK inhibitor (NU7026) to treat human osteosarcoma cells (U2OS) and assessed if the inhibition worked by blotting for pDNA-PKcs (S2056). The inhibitor works extremely well!
