pA-2′-p

In pA-2′-p phosphate groups are attached to both the ribose 2′ position and the ribose 5′ position of adenosine. It is an inhibitor of P2Y₁  and exhibits non-selective antagonism at recombinant and human platelet P2X₁ receptors. pA-2′-p inhibits ADP-induced platelet shape change and aggregation but it does not affect ADP-induced inhibition of adenylyl cyclase.
