Poly(ADP-ribose)polymerase-1 (PARP-1) has emerged as a promising anticancer drug target due to its key role in the DNA repair process. In this work, a novel series of 1-benzyl-quinazoline-2,4(1H,3H)-dione derivatives were designed and synthesized as human PARP-1 inhibitors, structure-activity relationships were conducted and led to a number of potent PARP-1 inhibitors having IC50 values of single or double digit nanomolar level. Compound 7j was a potent PARP-1 and PARP-2 inhibitor and it could selectively kill the breast cancer cells MX-1 and MDA-MB-468 with mutated BRCA1/2 and PTEN, respectively, in comparison with homologous recombination proficient cell types such as breast cancer cells MDA-MB-231. In addition, compound 7j displayed the strongest potentiation effect on temozolomide in MX-1 cells (PF50=3.77) in this series of PARP-1 inhibitors.
