Cyclic ADP-ribose ammonium (cADPR ammonium) is a powerful calcium mobilization second messenger synthesized from NAD+ by an ADP-ribosyl cyclase. It primarily raises cytosolic calcium levels through Ryanodine receptor-mediated release from the endoplasmic reticulum, while also facilitating extracellular influx through the opening of TRPM2 channels [1][2][3].
Cyclic ADP-ribose (cADP-ribose) is a calcium mobilizing nucleotide that is biosynthesized from NAD+ by cADP-ribose synthases, including CD38. cADP-Ribose appears to activate calcium channels in intracellular membranes, which in turn activate ryanodine receptors. 8-bromo-cADP-Ribose is a stable, cell-permeable analog that blocks calcium release evoked by cADP-ribose in sea urchin egg homogenates with an IC50 value of 1.7 μM. It is commonly used to investigate intracellular signaling through cADP-ribose in isolated cells and tissues.

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.
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.
