in potency for competition ligand binding assays using [32P]NAADP. In contrast, several 5-substituted NAADP derivatives showed high potency for binding and full agonist activity for Ca2+ release. 5-Azido-NAADP was shown to release calcium from seaurchin egg homogenates at low concentration and to compete with [32P]NAADP in a competition ligand binding assay with an IC50 of 18 nM, indicating that this
