Repair of DNA double-strand breaks (DSBs) is critical for the maintenance of genome integrity, cell survival, and prevention tumorigenesis. Three pathways are responsible for the repair of DNA DSBs: homologous recombination (HR), single strand annealing (SSA) and non-homologous end joining (NHEJ). DNA-dependent Protein Kinase (DNAPK), the key component of the NHEJ pathway, becomes an important target for cancer therapy. A large number of small molecules exhibit inhibitory activities against DNA-PK in an ATP-competitive manner. This paper reviews the recent developments of a diversity of small molecule DNA-PK inhibitors, with emphasis on their structural features, biological activities, and structure-activity relationships (SARs).

Keywords: Anticancer, anticancer agents, ATP-competitive inhibitors, chemo- and radio-potentiation, DNA-dependent protein kinase (DNA-PK), DNA double-strand breaks (DSBs), DNA-PK inhibitors, DNA-PK catalytic subunit, PI3K, cytotoxicity, inhibitory activity, kinase selectivity.
