生物活性

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].

IC50 & Target

IC50: 5-30 μM (RAD51)[1]
体外研究
(In Vitro)

RI-1 (1-50 µM; 24 h) specifically inhibits homologous recombination (HR) in U2OS cells and stimulates single-strand annealing (SSA) in HEK293 cells[1].
RI-1 (5-20 µM; 30 min) inhibits HsRAD51 in a concentration-dependent manner[1].
RI-1 (20 µM; 8 h) disrupts the formation of RAD51 foci after DNA damage in immortalized human fibroblasts[1].
RI-1 (15-25 µM; 24 h) sensitizes human cancer cells (HeLa, MCF-7 and U2OS) to cross-linking chemotherapy[1].
