Abstract
Adenosine 5′‐diphosphate (ADP) induces human platelet aggregation and noncompetitively inhibits stimulated human platelet adenylate cyclase; it has been suggested that these two effects are mediated by separate ADP receptors on the platelet surface. Adenosine 5′‐triphosphate and seven adenine nucleotide analogues were tested as inhibitors of both effects of ADP on human platelets, and were found to be competitive. pA2 values were calculated for each antagonist for inhibition of both effects of ADP, and a good correlation (correlation coefficient 0.87; P < 0.01) was found between the pA2 values for inhibition of ADP‐induced aggregation and the pA2 values for inhibition of the effect of ADP on stimulated adenylate cyclase. Such a correlation does not support the suggestion that ADP‐induced aggregation and the inhibition by ADP of stimulated adenylate cyclase are mediated by two separate receptors.
