Checkpoint kinase 2 is a serine/threonine protein which functions as an important transducer in apoptosis or DNA repair following activation by DNA damage. Inhibition of checkpoint kinase 2 is thought to sensitize p53-mutated or p53-deficient cancerous cells but protect normal tissue following DNA-damage caused by ionizing radiation or chemotherapeutic agents. The development of checkpoint kinase inhibitors for the treatment of cancer has therefore been a major objective in drug discovery over the past decade. Several inhibitors have been co-crystallized in the active site of checkpoint kinase 2 revealing important features of effective inhibitors. Some of these inhibitors have entered clinical trials in the last decade. This review describes and discusses the most recent inhibitors of checkpoint kinase 2 as reported in the literature, including an evaluation of biological activity.
