Poly-(ADP-ribose)-polymerase (PARP) is a promising anti-cancer target as it plays a crucial role in the cellular reparation and survival mechanisms. A series of benzofuran-7-carboxamides was designed to maintain the required pharmacophore conformation through an intramolecular hydrogen bond. Twelve compounds were synthesized and the inhibitory effect on PARP activity of these compounds were tested and evaluated. The results showed that all the target compounds displayed potency against the PARP enzyme, and compound 7c was the most potent one with an IC₅₀value of 20.5 nmol稬^-1.

Key words: PARP inhibitor, Benzofuran-7-carboxamide, anti-tumor , synthesis
