CCT244747 is primarily used in research settings as a potent and selective inhibitor of CHK1 (Checkpoint Kinase 1). It plays a significant role in studying the DNA damage response pathway, particularly in cancer research. By inhibiting CHK1, it helps researchers understand how cancer cells respond to DNA damage and explore potential therapeutic strategies. This compound is often utilized in preclinical studies to evaluate its efficacy in sensitizing cancer cells to chemotherapy or radiation, thereby enhancing their effectiveness. Additionally, it aids in investigating the mechanisms of cell cycle regulation and apoptosis, providing insights into novel cancer treatments.
