CAY10760 is an inhibitor of the protein-protein interaction between RAD51 recombinase and BRCA2 (EC50 = 19 µM in a cell-free competitive ELISA).1 It decreases homologous recombination by 54% in wild-type BRCA2-expressing BxPC-3 pancreatic cancer cells when used at a concentration of 20 µM. CAY10760 (20 µM) decreases proliferation of BxPC-3, as well as mutant BRCA2-expressing Capan-1, cancer cells when used alone or in combination with the poly(ADP-ribose) polymerase (PARP) inhibitor olaparib .
