amino alcohols is incorporated in its preferred conformation in the ring of the 2-(3,4-dihydroxyphenyl)-morpholines 9 and 10 (2-DPMs) and in the ring of the 3-(3,4-dihydroxyphenyl)-3-piperidinols 11 and 12 (3-DPPs), respectively, were synthesized and assayed for their adrenergic activity on various isolated preparations. The 2-DPMs and the 3-DPPs showed an alpha- and beta-agonist activity comparable
去甲肾上腺素(NE,7)和异丙肾上腺素(ISO,8)的两种环状类似物,其中这些氨基醇的C(1)-C(2)侧链以其优选的构象结合在2的环中分别合成了-(3,4-二羟基苯基)-吗啉9和10(2-DPM),以及在3-(3,4-二羟基苯基)-3-哌啶子基11和12(3-DPP)的环中。并测定了它们对各种分离制剂的肾上腺素能活性。2-DPM和3-DPP显示出与NE和ISO以及反式-2-氨基-5,6-二羟基四氢萘-1-醇13和14相当的α和β激动剂活性(2 -ADTN),代表NE和ISO的另一种半刚性类似物。通过比较所检查化合物的立体结构及其药理特性,有可能暗示一种空间状况,其中所检查的肾上腺素能药物的药效基团(芳基部分,胺氮以及醇或醚苄氧基)应在受体部位相互作用。这种空间状况与在NE和ISO的首选构型中发现的状况相对应。也可以构建两个理论的三维分子模型,分别提供有关直接激活α-和β-肾上腺素受体的空间需求的信息。
