compounds were tested as activators of dopamine-sensitive adenylate cyclase (a measure of DA-1 agonist activity) and as renal vasodilators. All three O-methyl derivatives were much less potent than 1 in cyclase activation and as renal vasodilators. Weak inhibition of adenyl cyclase was also observed for all three compounds and one showed weak renal vasoconstrictor activity. Preliminary investigation of the
6-氯-2,3,4,5-四氢-1-(4-羟基苯基)-1 H -3-苯并ze庚因-7,8-二醇的三种可能的单-O-甲基衍生物(SK&F 82526)(1)已合成,以促进该化合物代谢物的分离和表征以及用于生物学测试。合成通常涉及制备适当取代的苯甲醛,将其转化为苯乙酸并将其转化为N-酰化芳基乙醇胺。由此形成的苯基乙酰胺被还原为胺,并且将它们脱保护并环化为所需的最终产物。在一种情况下,脱保护是在环化之后。测试了这些化合物作为多巴胺敏感的腺苷酸环化酶的活化剂(DA-1激动剂活性的量度)和肾血管扩张剂。所有三种O-甲基衍生物在环化酶激活和作为肾血管舒张剂方面的效力均远低于1。还观察到所有三种化合物对腺苷酸环化酶的抑制作用较弱,其中一种显示出弱的肾血管收缩活性。1的代谢的初步研究美国专利No.5,644,837公开了三种单甲氧基化合物中的两种是在大鼠和狗中以痕量形式形成的。在相关的研究中,对1的三甲氧基
