Adenosine diphosphate ribose (ADPR) is an ester molecule formed into chains by the enzyme poly ADP ribose polymerase.[1] ADPR is created from cyclic ADP-ribose (cADPR) by the CD38 enzyme using nicotinamide adenine dinucleotide (NAD+) as a cofactor.[1]

ADPR binds to and activates the TRPM2 ion channel.[2] ADPR is the most potent agonist of the TRPM2 channel.[3] cADPR also binds to TPRM2, and the action of both molecules is synergistic, with both molecules enhancing the action of the other molecule in activating the TRPM2 channel.[4]
