Description

General description

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 5-30 µM concentration. Inhibits subnuclear RAD51 foci formation following DNA damage without affecting replication protein A. Also, effectively sensitizes cancer cells to mitomycin C (~25 µM) 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.
