pNP-ADPr is a colorimetric substrate employed in the first continuous activity assays for Poly(ADP-ribose) glycohydrolase (PARG) and ADP-ribosyl hydrolase 3 (ARH3). Its utilization facilitates research on poly(ADP-ribose) polymerase (PARP) enzymes.
PDD00017238 demonstrates a robust inhibitory effect on Poly(ADP-ribose) Glycohydrolase (PARG), displaying EC50 values of 40 nM in biochemical assay and 55 nM in cell POM assessment.
