UPF 1069 is primarily utilized in research settings as a selective PARP-1 inhibitor, making it a valuable tool for studying the role of PARP-1 in cellular processes. It is often employed in experiments focused on DNA repair mechanisms, particularly in understanding how PARP-1 inhibition affects cell survival and genomic stability. This compound is also used in studies exploring its potential therapeutic applications, such as in cancer research, where PARP-1 inhibition can sensitize cancer cells to treatments like chemotherapy and radiation. Additionally, UPF 1069 is applied in neuroprotective studies to investigate its effects on oxidative stress and inflammation in neurodegenerative diseases. Its ability to modulate PARP-1 activity makes it a key compound in both basic and applied biomedical research.
