Biochem/physiol Actions

KU-0060648 is a very potent dual inhibitor of DNA-PK and PI3K. The IC50 values for inhibition of DNA-PK in MCF7 and SW620 cells are 19 and 170 nM, respectively. The compound KU-0060648 inhibits MCF7 PI3K activity with an IC50 of 39 nM, but is inactive against PI3K in SW620, suggesting a cell-dependent mechanism of inhibition. KU-0060648 increases sensitivity to DNA damaging cytotoxic drugs such as etoposide and doxorubicin in tumor cell lines expressing DNA-PK. KU-0060648 stimulates Cas9 (CRISPR associated protein 9) mediated genome editing by enhancing the rate of homology directed-repair (HDR) and decreasing the rate of NHEJ (non-homologous end-joining).
KU-0060648 is observed to inhibit proliferation and initiate apoptosis in hepatocellular carcinoma. KU-0060648 is useful in chemotherapy as it increases the efficiency of double stranded breaks initiated by anticancer drugs.

DNA double-strand breaks (DSB) are the most cytotoxic lesions induced by topoisomerase II poisons. Nonhomologous end joining (NHEJ) is a major pathway for DSB repair and requires DNA-dependent protein kinase (DNA-PK) activity. DNA-PK catalytic subunit (DNA-PKcs) is structurally similar to

Poly(ADP-ribosyl)polymerase (PARP) synthesizes poly(ADP-ribose) (PAR), which is anchored to proteins. PAR facilitates multiprotein complexes' assembly. Nuclear PAR affects chromatin's structure and functions, including transcriptional regulation. In response to stress, particularly genotoxic stress, PARP activation facilitates DNA damage repair. The PARP
