Description: YU238259 Is a Novel Inhibitor of Homology-Dependent DNA Repair. YU238259 exhibits potent synthetic lethality in the setting of DNA damage response and DNA repair defects. YU238259 specifically inhibits homology-dependent DNA repair, but not non-homologous end-joining, in cell-based GFP reporter assays. Treatment with YU238259 is not only synergistic with ionizing radiation, etoposide, and PARP inhibition, but this synergism is heightened by BRCA2 deficiency.

Further, growth of BRCA2-deficient human tumor xenografts in nude mice is significantly delayed by YU238259 treatment even in the absence of concomitant DNA-damaging therapy. The cytotoxicity of these small molecules in repair-deficient cells results from an accumulation of unresolved DNA double-strand breaks. YU238259 or related small molecules may have clinical benefit to patients with advanced BRCA2-negative tumors, either as a monotherapy or as an adjuvant to radiotherapy and certain chemotherapies.
