title: Novel nucleobase-simplified cyclic ADP-ribose analogue: A concise synthesis and Ca(2+)-mobilizing activity in T-lymphocytes.
abstract: A purine nucleobase-simplified cyclic ADP ribose (cADPR) analogue was synthesized, in which a 1,2,3-triazole-4-amide was constructed, instead of a purine moiety, and the northern ribose was replaced by an ether strand. Compound exhibits calcium release activity in intact T-lymphocytes and indicates that it is a membrane-permeable cADPR mimic. Thus, the cADPR analogue containing 1,2,3-triazole-4-amide provides a novel template for further designing cADPR analogues and elucidating their structure-activity relationships.
