Poly(ADP-ribose) Polymerase Inhibitors Small Molecules and Peptides

Poly (ADP-ribose) polymerase (PARP) catalyzes the post-translational modification of proteins by the addition of multiple ADP-ribose moieties. PARP transfers ADP-ribose from nicotinamide dinucleotide (NAD) to Glu/Asp residues on the substrate protein, and also polymerizes ADP-ribose to form long/branched chain polymers. Tankyrase proteins also display PARP activity.

PARP-1, one of 5 confirmed PARPs, is the most abundant and highly expressed PARP enzyme. PARP-1 detects and relocates to single ...
