DPQ is widely used in scientific research, particularly in the study of cellular processes and mechanisms. It is often employed as an inhibitor of poly(ADP-ribose) polymerase (PARP), an enzyme involved in DNA repair and programmed cell death. By inhibiting PARP, DPQ helps researchers understand the role of this enzyme in conditions such as cancer, neurodegenerative diseases, and inflammation. Additionally, DPQ is utilized in experiments exploring the effects of DNA damage and the pathways involved in cellular stress responses. Its application extends to pharmacological studies, where it aids in the development of potential therapeutic agents targeting PARP-related mechanisms. Overall, DPQ serves as a valuable tool in advancing knowledge in molecular biology and drug discovery.
