Cyclic ADP-ribose ammonium (cADPR ammonium) is a potent calcium mobilization second messenger synthesized from NAD+ by ADP-ribosyl cyclase. It raises cytosolic calcium levels through Ryanodine receptor-mediated release from the endoplasmic reticulum and facilitates extracellular influx via TRPM2 channels [1][2][3].

ADP-ribose/PARP-IN-1 (Compound Ex.16) is a conjugated compound composed of a disease-targeting segment, a PARP inhibitor section, a cleavable linker, and a chelating agent. It targets specific sites via its disease-targeting part, delivering the PARP inhibitor selectively to tumor cells. Under suitable conditions, the cleavable linker releases the PARP inhibitor to hinder DNA damage repair by inhibiting PARP, while the chelating agent transports a radionuclide for cytotoxic action. This compound is applicable in prostate cancer research.

Cyclic ADP-Ribose (ammonium salt) (cADPR) is an endogenous NAD⁺ metabolite that triggers Ca²⁺ release from ER stores via ryanodine receptors and is synthesized by CD38 and CD157.
