Values are EC50 (nM). Experiments involved at least four replicates. Receptor subtype involvement is given (•) under the description of each preparation. Physiological responses are as follows: feline iris=contraction; Swiss 3T3 cells=Ca2+ ↑; rabbit jugular vein=relaxation; guinea-pig ileum=contraction; guinea pig vas deferens=inhibition of field stimulated contraction; human platelets (TP)=aggregation; human platelets (DP, IP)=inhibition of ADP induced aggregation.
