yl)amino]-3-(aryloxy)propan-2-ols was synthesized together with several 1-[(3,4-dimethoxyphenethyl)amino]-3-(aryloxy)propan-2-ols. Their affinity to beta 1- and beta-2-adrenoceptors was determined and compared with the affinity of known beta-blockers. We were able to confirm the substantial cardioselectivity of 1-(3,4-dimethoxyphenethyl)-3-[(4-substituted aryl)oxy]propan-2-ols when compared to those
合成了一系列的1-[((4-羟基苯乙基)氨基] -3-(芳氧基)丙烷-2-醇和几个1-[((3,4-二甲氧基苯乙基)氨基] -3-(芳氧基)丙烷-2。 -ols。确定了它们对β1和β2肾上腺素受体的亲和力,并将其与已知β受体阻滞剂的亲和力进行了比较。当与具有1-(4-羟基苯乙基)基团的那些相比时,我们能够确认1-(3,4-二甲氧基苯乙基)-3-[(4-取代的芳基)氧基]丙烷-2-醇的基本心脏选择性。在存在3,4-二甲氧基苯乙基的情况下,3-(芳氧基)部分对己内酰胺基的4个取代基的大小增加导致对大鼠心室肌β1-肾上腺素受体的亲和力大大高于在存在下4-羟基苯乙基或异丙基;这种组合还具有最高的心脏选择性。
