Poly(ADP-ribose) polymerase-1 (PARP-1), a critical DNA repair enzyme in the base excision repair pathway, has been pursued as an attractive cancer therapeutic target. Intervention with PARP-1 has been proved to be more sensitive to cancer cells carrying BRCA1/2 mutations. Several PARP-1 inhibitors have been available on market for the treatment of breast, ovarian and prostatic cancer. Promisingly, the newly developed proteolysis targeting chimaeras (PROTACs) may provide a more potential strategy based on the degradation of PARP-1. Here we report the design, synthesis, and evaluation of a proteolysis targeting chimaera (PROTAC) based on the combination of PARP-1 inhibitor olaparib and the CRBN (cereblon) ligand lenalidomide. In SW620 cells, our probe-quality degrader compound 2 effectively induced PARP-1 degradation which results in anti-proliferation, cells apoptosis, cell cycle arresting, and cancer cells migratory inhibition. Thus, our findings qualify a new chemical probe for PARP-1 knockdown.

Poly(ADP-ribose)polymerase (PARP) is a significant therapeutic target for the treatment of numerous human diseases. Olaparib has been approved as a PARP inhibitor. In this paper, a series of new compounds were designed and synthesized with Olaparib as the lead compound. In order to evaluate the inhibitory activities against PARP1 of the synthesized compounds, in vitro PARP1 inhibition assay and intracellular PARylation assay were conducted. The results showed that the inhibitory activities of the derivatives were related to the type of substituent and the length of alkyl chain connecting the aromatic ring. 3-(4,5-Dimethyl- 2-thiazolyl)-2,5-diphenyl-2H-tetrazolium bromide (MTT)-based assay also proved that these compounds demonstrating strong inhibition to PARP1 also have high anti-proliferative activities against BRCA2-deficient cell line (Capan-1). Analysis of the entire results suggest that compound 23 with desirable inhibitory efficiency may hold promise for further in vivo exploration of PARP inhibition.
