The poly (ADP-ribose) polymerase (PARP) inhibitors play a crucial role in cancer therapy. However, most approved PARP inhibitors have lower selectivity to PARP-1 than to PARP-2, so they will inevitably have side effects. Based on the different catalytic domains of PARP-1 and PARP-2, we developed a strategy to design and synthesize highly selective PARP-1 inhibitors. Compounds Y17, Y29, Y31 and Y49 showed excellent PARP-1 inhibition, and their IC50 values were 0.61, 0.66, 0.41 and 0.96 nM, respectively. Then, Y49 (PARP-1 IC50 = 0.96 nM, PARP-2 IC50 = 61.90 nM, selectivity PARP-2/PARP-1 = 64.5) was proved to be the most selective inhibitor of PARP-1. Compounds Y29 and Y49 showed stronger inhibitory effect on proliferation in BRCA1 mutant MX-1 cells than in other cancer cells. In the MDA-MB-436 xenotransplantation model, Y49 was well tolerated and showed remarkable single dose activity. The design strategy proposed in this paper is of far-reaching significance for the further construction of the next generation of selective PARP-1 inhibitors.
