Adenosine 5′-diphosphoribose sodium (ADP ribose sodium) is a nicotinamide adenine nucleotide (NAD⁺) metabolite. Adenosine 5′-diphosphoribose sodium is the most potent and primary intracellular Ca²⁺-permeable cationTRPM2 channelactivator. Adenosine 5′-diphosphoribose sodium also can enhanceautophagy^[1][2].

TRPM2 channel^[1][2]
Autophagy^[1]

In mouse embryonic fibroblasts (MEFs), H₂O₂treatment demonstrates that the activation of poly(ADP-ribose) (PAR) polymerase-1 (PARP-1) produced Adenosine 5′-diphosphoribose (ADP ribose), which is an activating signal for TRPM2 channels, thereby promoting Ca²⁺elevation through extracellular Ca²⁺influx and (or) lysosomal Ca²⁺release. This process eventually activates early or late autophagy in response to different degrees of oxidative stress^[1][1].
TRPM2 channels are activated by binding of Adenosine 5′-diphosphoribose (ADP ribose) to the intracellular NUDT9-homology (NUDT9-H) domain unique to TRPM2 and located at its C terminus. In addition to ADPR, intracellular Ca²⁺is an essential coactivator: TRPM2 channels open only in the combined presence of both ligands^[2].
