Abstract:
Poly(ADP-ribose) polymerases (PARPs) are a family of enzymes, which show differences in structure, cellular location and functions. However, all these enzymes possess poly(ADP-ribosyl)ation activity. Overactivation of PARP enzymes has been implicated in the pathogenesis of several diseases, including stroke, myocardial infarction, diabetes, shock, neurodegenerative disorder and allergy. The best studied of these enzymes (PARP-1) is involved in the cellular response to DNA damage so that in the event of irreparable DNA damage overactivation of PARP-1 leads to necrotic cell death. Inhibitors of PARP-1 activity in combination with DNA-binding antitumor drugs may constitute a suitable strategy in cancer chemotherapy. In addition, PARP inhibitors may be also useful to restore cellular functions in several pathophysiological states and diseases. This review gives an update of the state-of-the-art concerning PARP enzymes and their exploitation as pharmacological targets in several illnesses.
