Description
Summary:Herein, we report on the synthesis of a small set of linear precursors of an inosine analogue of cyclic ADP-ribose (cADPR), a second messenger involved in Ca<sup>2+</sup> mobilization from ryanodine receptor stores firstly isolated from sea urchin eggs extracts. The synthesized compounds were obtained starting from inosine and are characterized by an N1-alkyl chain replacing the &#8220;northern&#8221; ribose and a phosphate group attached at the end of the N1-alkyl chain and/or 5&#8242;-sugar positions. Preliminary Ca<sup>2+</sup> mobilization assays, performed on differentiated C2C12 cells, are reported as well.
