Cayman Ku-0060648

Ku-0060648 is an ATP-competitive inhibitor of DNA-dependent protein kinase (DNA-PK) and an inhibitor of PI3K. In a cell-free assay, it has IC₅₀s of 5, 4, 0.5, <0.1, and 594 nM for DNA-PK, PI3Kα, PI3Kβ, PI3Kδ, and PI3Kγ, respectively. In cells, the level of PI3K inhibition is variable, depending upon the cell line utilized. In MCF-7 cells, it has IC₅₀s of 19 and 39 nM, for DNA-PK and PI3K, respectively, while in SW620 cells, it has an IC₅₀ of 170 nM for DNA-PK but >10,000 nM for PI3K. Ku-0060648 is useful for Cas9 editing due to its DNA-PK inhibition, which reduces the frequency of non-homologous end joining and increases homology-directed recombination. It also shows promise in cancer research in vitro and in vivo.^,
