CAM833

CAM833 (CAM-833) is a potent, specific chemical inhibitor of the RAD51-BRCA2 interaction and RAD51 oligomerization with Kd of 366 nM;CAM833 inhibited RAD51 foci formation 6 h after exposure to 3 Gy IR, in a concentration-dependent manner with an IC50 of 6 uM, causeed a concentration-dependent decrease in RAD51 foci accompanied by increased DNA damage in A549 cells.CAM833 inhibted RAD51 molecular clustering at DNA damage sites visualized by SMLM, suppressed homologous recombination and potentiated cell-cycle arrest.CAM833 potentiated the growth suppressive effect of PARP1 inhibition in BRCA2 wild-type cells, as well as dose-dependent growth inhibition when combined with ionizing radiation.
