8-Br-ADPR
8-Br-ADPR (8-Bromoadenosine-5'-O-diphosphoribose) is a TRPM2 inhibitor and ADPR signaling pathway antagonist. 8-Br-ADPR inhibits glucagon-mediated nuclear calcium signaling and downstream CaMKII/CREB phosphorylation by blocking ADPR-induced TRPM2 activation. 8-Br-ADPR significantly reduces gluconeogenic gene expression and blood glucose levels in diabetic models. 8-Br-ADPR effectively blocks ADPR-mediated calcium signal transduction in NK cells, inhibits immune synapse formation, granzyme B release and cytolytic activity against melanoma cells. 8-Br-ADPR is widely used in studies related to diseases such as diabetes, melanoma and lymphoma.
