BML210 is primarily utilized in biochemical research as a potent and selective inhibitor of the PARP-1 enzyme, which plays a critical role in DNA repair mechanisms. Its application is significant in studies focused on understanding cellular responses to DNA damage and the development of therapeutic strategies for cancer. By inhibiting PARP-1, BML210 induces synthetic lethality in cancer cells with defective DNA repair pathways, making it a valuable tool in preclinical cancer research. Additionally, it is used to explore the role of PARP-1 in various biological processes, including inflammation and neurodegeneration, providing insights into potential treatments for related diseases.
