A series of dinucleoside 5-polyphosphates UpnU (n = 2-7) was synthesized. Their relative potencies as agonists at the G-protein-coupled receptors P2Y1, P2Y2, P2Y4, and P2Y6 were determined by intracellular calcium measurements using fluorescent imaging techniques. The correlation of phosphate chain length to activities at these receptors is discussed.
