MK-4827 (also known as Niraparib)（Cat No.:I000230）is a potent, selective inhibitor of poly(ADP-ribose) polymerase (PARP), an enzyme involved in DNA repair. By inhibiting PARP, MK-4827 induces synthetic lethality in cancer cells with deficiencies in homologous recombination repair mechanisms, such as those with BRCA1/2 mutations. This makes it particularly effective in treating ovarian, breast, and other cancers with such genetic vulnerabilities. MK-4827 has shown promise in both preclinical and clinical studies, making it a valuable tool in oncology research and a potential therapeutic option for targeted cancer treatment.
