the ability of 2-ohe2 ( ic50 = 20-30 micro m ) to inhibit ligand binding to alpha 1 receptors was comparable to that of norepinephrine ( ic50 = 10-20 micro m ) , whereas for dopamine receptors in striatum and pituitary 2-ohe2 was an order of magnitude less effective than dopamine ( ic50 = 12 micro m ) in reducing binding of 3h ligands .
