During the last dopamine (DA) symposium at Southampton we reviewed the characteristics of the DA vascular receptor and compared these data with characteristics of putative DA receptors identified in other areas (Goldberg, 1978). At that time we had studied more than 200 close structural analogs of DA and found that only a few compounds were active as DA agonists. Most of our studies were conducted in the canine renal vascular bed pretreated with phenoxybenzamine (POB) to prevent alpha-adrenergic vasoconstriction. A positive compound had to increase renal blood flow following intra-arterial administration and be specifically antagonized by a DA antagonist: haloperidol, in the initial investigations, and sulpiride in later studies. On the basis of the results obtained with this technique, we established a potency series of agonists as follows: DA = epinine = A-6,7-DTN = N-methyl -A-6,7-DTN > N,N-di-n-propyl DA > N-n-propyl apomorphine > apomorphine (partial agonist). Ergot derivatives and piribedil were totally inactive. When we compared the DA activity of these compounds on presynaptic and ganglionic preparations in which DA inhibits sympathetic activity, we found the potency series and relative activity of these agonists to be totally different.
