A series of 2-(tetrahydroisoquinolin-2-ylmethyl)- and 2-(isoindolin-2-ylmethyl)imidazolines were prepared and tested for alpha 1- and alpha 2-adrenoceptor affinity with radioligand binding. Several compounds, 5-fluoro-(5h), 5-chloro-(5j), 5,8-dimethoxy- (5r), and 5,8-dimethoxy- (5r),1-methyl- (5s) 2-(tetrahydroisoquinolin-2- ylmethyl)imidazoline, were found to be selective alpha 2-adrenoceptor ligands
制备一系列2-(四氢异喹啉-2-基甲基)-和2-(异吲哚-2-基甲基)咪唑啉,并通过放射性配体结合测试α1-和α2-肾上腺素受体的亲和力。几种化合物5-氟-(5h),5-氯-(5j),5,8-二甲氧基-(5r)和5,8-二甲氧基-(5r),1-甲基-(5s)2-(基于[3H]育亨宾从大鼠大脑皮膜的置换,发现四氢异喹啉-2-基甲基)咪唑啉是选择性的α2-肾上腺素受体配体。一种化合物2-[((8-氯四氢异喹啉-2-基)甲基]咪唑啉(5m)与[3H]育亨宾相比,对[3H] idazoxan标记的α2-肾上腺素受体的亲和力显示出36倍的差异-标记的位点,可能是α2-肾上腺素受体亚型的证据。
