Structure-function of alpha1-adrenergic receptors
WebWe have utilized a rat primary hepatocyte culture system to show that the alpha 1-adrenergic receptor can be activated in a stereoselective manner by a series of phenethylamines and catecholimidazolines resulting in the stimulation of DNA synthesis as determined by [3H]thymidine incorporation. WebFor all 1 -AR ligands, there is a so-called Easson-Stedman hypothesis for illustrating their interaction with the receptors as revealed in Fig. (3), in which states that catecholamines bind with ...
