【 摘 要 】
Novel cADPR mimics, which integrate nucleobase, northern and southern ribose modifications were synthesized. The key steps of the synthesis were a Cu(I)-catalyzed Hüisgen [3+2] cycloaddition and a microwave-assisted intramolecular pyrophosphorylation. Preliminary biological investigations showed that these cADPR mimics are membrane-permeating agonists of the calcium signaling pathway. The introduction of chlorine or fluorine at the 2'-position of the southern riboses led to a decrease of activity. The existence of a hydrophobic group on the 3'-OH of the southern riboses does not obviously alter the agonistic activity.
