  7,8-dimethoxy-5-(4-methoxyphenyl)-2,3,4,5-tetrahydro-1H-3-benzazepine 在 三溴化硼 、 potassium carbonate 作用下， 以 二氯甲烷 、 水 、 N,N-二甲基甲酰胺 为溶剂， 反应 3.0h， 生成 N-allyl-2,3,4,5-tetrahydro-1-(4-hydroxyphenyl)-1H-3-benzazepine-7,8-diol hydrobromide

  Dopamine agonists related to 3-allyl-6-chloro-2,3,4,5-tetrahydro-1-(4-hydroxyphenyl)-1H-3-benzazepine-7,8-diol, 6-position modifications

  摘要：

  The N-allyl derivative (SK&F 85174) of 6-chloro-2,3,4,5-tetrahydro-1-(4-hydroxyphenyl)-1H-3-benzazepine-7,8-diol (SK&F 82526) retains the DA-1 agonist potency of the latter compound but unlike the parent also shows substantial DA-2 agonist activity. In a previous study of N-substituted benzazepines these combined agonist effects were shown to be uniquely associated with the N-allyl group. A continuation of this research has examined dependency of combined DA-2/DA-1 agonist activities on 6-position modification with the specific objective of developing an agonist with maximum effectiveness and potency at the DA-2 receptor subtype. DA-2 agonist activity was measured in a rabbit ear artery assay, and DA-1 agonist activity was determined in an adenylate cyclase assay. Replacing chloro with bromo retains the activity pattern and the potency of the chloro compound; replacement with a hydrogen causes a decrease of both DA-1 and DA-2 receptor activating potency. Introduction of a 6-methyl group causes loss of DA-2 agonist activity and reduction in DA-1 agonist potency. Substitution with a 6-fluoro provides the best balance of DA-2 and DA-1 agonist activities; this compound was moderately potent in both assays.

  Certain 6-halo-1-phenyl-2,3,4,5-tetrahydro-1H-3-benzazepines were found to be potent D-1 dopamine agonists. The 1-(4-hydroxyphenyl) analogues did not have central nervous system activity because their high polarity inhibited entry into the brain. However, these compounds were potent renal vasodilators. Fenoldopam, the 6-chloro analogue, is an especially significant member of the series, and its synthesis
