A-196 is a potent and selective inhibitor of SUV420H1 and SUV420H2 ((IC50 values of 25 and 144 nM, respectively). In cells, A-196 induced a global decrease in H4K20me2 and H4K20me3 and a concomitant increase in H4K20me1. A-196 inhibited 53BP1 foci formation upon ionizing radiation and reduced NHEJ-mediated DNA-break repair but did not affect homology-directed repair.
