4-amino-1,8-Naphthalimide is a novel inhibitor of PARP with IC50 value of 180 nM .
The poly(ADP-ribose) polymerases (PARPs) is a nuclear enzyme that catalyzes a transfer of the ADP-ribose moiety of NAD+ to acceptor protein with a concomitant release of nicotinamide. PARPs play important roles in DNA repair, cell differentiation, control of cell cycle, transformation, transcription, and alteration of chromatin architecture .
4-amino-1,8-Naphthalimide (4-ANI) is a novel PARP inhibitor and a radiation sensitizer. In exponentially growing hamster lung fibroblasts (V79), rat prostate carcinoma (R3327-AT1) and human prostate carcinoma (DU145) cells, 4-ANI significantly potentiated the cytotoxicity of gamma-irradiation in a dose dependent way and is not cytotoxic in the absence of radiation. 4-ANI was used to study the role of PARP activity in a variety of cell systems .
