Concise synthesis of novel acyclic analogues of cADPR with an ether chain as the northern moiety

Abstract

To study the properties of hydrolysates of cyclic adenosine diphosphate ribose (cADPR), a series of novel acyclic analogues of cADPR with an ether chain as the northern moiety and 8-substituted adenine or hypoxanthine as the base moiety were synthesized via an N1 substitution construction, followed by bisphosphorylation, phosphoramidition or pyrophosphorylation. These compounds also provide various precursors for synthesizing cADPR analogues.
