Characteristics of 1251-lodocyanopindolol Binding to 8-Adrenergic and Serotonin-1B Receptors of Rat Brain: Selectivity of 19-Adrenergic Agents

The present study was designed to examine the specificity of (3-adrenergic antagonists for al-, 192-adrenergic and 5HT1B-serotonergic receptors by the compe titive interaction with 1251-iodocyanopindolol (1251-ICYP) as a radioligand. The 81 -adrenoceptors were preferred by acebutolol, atenolol, betaxolol, practolol, and I-, dl and d-metoprolol, while butoxamine and ICI-118,551 preferred 82-adre...

Downregulation of myocardial beta-adrenergic receptors. Receptor subtype selectivity.

T he desensitization (loss of response) and downregulation (loss of receptors) of p-adrenergic receptors (,BAR) have been observed in several cardiac conditions, including certain forms of heart failure and hypertension. The inability of the failing heart to respond to inotropic agents such as catecholamines represents a major clinical problem. The downregulation of 131AR associated with certai...

Beta-Adrenergic Receptors

ion fluxes in these cells, we have now examined the possibility that the decrease in beta receptor number might be associated with concomitant changes in catecholamine-dependent potassium ion transport. Hypothyroid turkey erythrocytes display decreased sensitivity to isoproterenol-stimulated potassium influx. Half-maximal stimulation of potassium influx occurs at 9.2±+1.7 nM in hypothyroid cell...
