A cell-permeable 1H-Pyrrole-2,3-dione derivative that covalently binds to RAD51 at Cys319 and irreversibly destabilizes a protein-protein interface that is essential for filament formation and recombinase activity. Stimulates single strand annealing at a 5-30uM concentration. Inhibits subnuclear RAD51 foci formation following DNA damage without affecting replication protein A. Also, effectively sensitizes cancer cells to mitomycin C (~25uM) and generate synergistic cell kill in RAD51C mutant cells and with lesser effect on RAD51 complemented cells. Satisfies all four Lipinski rules for predicting drug likeness.
Storage and Stability:Lyophilized powder may be stored at -20°C. Stable for 12 months at -20°C. Reconstitute with sterile buffer or dH2O. Aliquot to avoid repeated freezing and thawing. Store at -20°C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
