RI-1

RI-1 is a RAD51 inhibitor, with IC50s ranging from 5 to 30 μM. RI-1 binds covalently to the surface of RAD51 protein at cysteine 319. RI-1 inactivates RAD51 by directly binding to a protein surface that serves as an interface between protein subunits in RAD51 filaments. RI-1 can disrupt homologous recombination in human cells[1].
