摘要

Abstract 4 (5)-(2, 2-diphenylethyl) imidazole 6a is described as being a potent (pK i= 8.16 for displacement of [3 H] p-amino-clonidine) and selective (selectivity=-log (pK i α 2-pK i α 1)= 81) α 2-adrenoreceptor antagonist (pA 2= 8.73 versus clonidine in the electrically stimulated guinea pig ileum) with additional activity as a norepinephrine uptake inhibitor (IC 50= 0.3 μM). An investigation of the structure-activity relationships of compounds closely related to ...
