Used in cancer research, particularly in studies involving breast and ovarian cancers. It was investigated for its ability to inhibit poly (ADP-ribose) polymerase (PARP), an enzyme involved in DNA repair. By blocking this enzyme, the compound aimed to enhance the effectiveness of chemotherapy and radiation by preventing cancer cells from repairing their DNA damage. Although it showed promise in early trials, later studies did not confirm significant clinical benefit, leading to discontinuation of further development for certain indications. Still, it contributed to the understanding of PARP inhibition in oncology.
