title: First enzymatic synthesis of an N1-cyclised cADPR (cyclic-ADP ribose) analogue with a hypoxanthine partial structure: discovery of a membrane permeant cADPR agonist.
abstract: Nicotinamide 8-Br-hypoxanthine dinucleotide (8-Br-NHD+) was cyclised at the N1 position by the ADP-ribosyl cyclase from Aplysia californica to give cyclic 8-Br-inosine diphosphoribose (8-Br-N1-cIDPR), a novel membrane-permeant agonist of Ca2+ release in human T cells.
