  • Patent number: 8293764
    Abstract: Contemplated compounds disrupt interaction between BRCA2 and RAD51, likely by binding to RAD51. Based on the crucial role of the BRCA2-RAD51 complex formation in DNA repair and the role of RAD51 in the control of entry into S-phase from G1, numerous compositions and methods are presented. Among other advantageous uses, contemplated compounds may be employed as protective agents for non-neoplastic cells in chemotherapy before exposure of the cells to a chemotherapeutic drug, and/or as DNA-damage sensitizer for neoplastic cells.
