In a search for a new structural type of β-adrenergic antagonist. a series of trans-2-(N-substituted amino)-1, 2, 3, 4-tetrahydronaphthalen-1-ol derivatives (3-36) was synthesized in several steps from 3, 4-dihydro-1 (2H)-naphthalenone (37) having a variety of substituents at the 5-, 6-, 7-and 8-positions. Compounds 3-36 were tested in vitro for β-adrenergic activity. Among them, 2-benzhydrylamino-6-chloro-1, 2, 3, 4-tetrahydronaphthalen-1-ol (28c) was found to show a fairly potent β-adrenergic blocking activity.
为了寻找一种新结构类型的 β-肾上腺素能拮抗剂,我们从 5、6、7 和 8 位上具有各种取代基的 3、4-二氢-1(2H)-萘酮(37)出发,通过几个步骤合成了一系列反式-2-(N-取代氨基)-1,2,3,4-四氢萘-1-醇衍生物(3-36)。体外测试了 3-36 号化合物的 β 肾上腺素能活性。其中,2-二苯甲基氨基-6-氯-1,2,3,4-四氢萘-1-醇(28c)显示出相当强的β-肾上腺素能阻断活性。
