Telomerase-IN-3 is primarily used in research focused on cancer treatment and aging studies. It functions as a telomerase inhibitor, targeting the enzyme telomerase, which is often overactive in cancer cells, allowing them to divide indefinitely. By inhibiting telomerase, this compound can potentially limit the uncontrolled growth of cancer cells, making it a promising candidate for anticancer drug development. Additionally, its role in telomerase inhibition provides insights into cellular aging processes, as telomerase activity is closely linked to telomere maintenance and cellular lifespan. Researchers utilize Telomerase-IN-3 to explore therapeutic strategies for age-related diseases and to better understand the mechanisms of cellular immortality in cancer.
