The present study was designed to demonstrate the existence in canine aorta of α<SUB>1</SUB>-adrenoceptor subtypes, α<SUB>1High</SUB> and α<SUB>1Low</SUB>, that have different binding affinities for <SUP>3</SUP>H-prazosin and to assess the binding affinity of several drugs for each subtype by a displacement experiment. A radioligand binding assay with <SUP>3</SUP>H-prazosin revealed the presence of two α<SUB>1</SUB>-adrenoceptor subtypes in the canine aorta. One of them which has a high affinity for prazosin was designated as α<SUB>1High</SUB> (K<SUB>d</SUB>: 12.40 pM, B<SUB>max</SUB>: 21.88 fmol/mg protein), and the other type was designated as α<SUB>1Low</SUB>(K<SUB>d</SUB>: 506.03 pM, B<SUB>max</SUB>: 88.22 fmol/mg protein). The pK<SUB>i</SUB> values of several drugs for each subtype were determined, and all drugs used in the present study, except for benoxathian and chlorethylclonidine, showed significant differences between the pK<SUB>1</SUB> values for α<SUB>1High</SUB> and those for α<SUB>1Low</SUB>. Although it is difficult to characterize each α<SUB>1High</SUB> and α<SUB>1Low</SUB> into α<SUB>1A</SUB> or α<SUB>1B</SUB> by only the displacement potency, one structural characteristic to distinguish between α<SUB>1High</SUB> and α<SUB>1Low</SUB> could be evaluated.
