  Mapping the Melatonin Receptor. 7. Subtype Selective Ligands Based on β-Substituted N-Acyl-5-methoxytryptamines and β-Substituted N-Acyl-5-methoxy-1-methyltryptamines

  摘要：

  A series of beta-substituted and beta,beta-disubstituted N-acyl 5-methoxy-1-methyltryptamines and 5-methoxy-tryptamines have been prepared as melatonin analogues to investigate the nature of the binding site of the melatonin receptor. The affinity of analogues was determined in a radioligand binding assay using cloned human MT(1) and MT(2) receptor subtypes expressed in NIH 3T3 cells. Agonist and antagonist potency of all analogues was measured using the pigment aggregation response of a clonal line of Xenopus laevis melanophores. beta-Methylmelatonin ( 17a) and beta,beta-dimethylmelatonin ( 17b), though showing a slight decrease in binding at human receptors, show an increase in potency on Xenopus. N-Butanoyl 5-methoxy-1-methyl-beta,beta-trimethylenetryptamine ( 12c) is an antagonist at human MT1 receptors but an agonist at MT2, while N-butanoyl 5-methoxy-1-methyl-beta,beta-tetramethylenetryptamine ( 13c) is an antagonist at MT1 but had no action at MT2 and is one of the first examples of an MT1 selective antagonist.

  A new, general, one pot method for introducing carbocyclic rings alpha to a nitrile moiety is described. Treatment of readily available arylacetonitriles with potassium bis(trimethylsilyl)amide and subsequent alkylation with α, ω-dibromo or dichloroalkanes in tetrahydrofuran under anhydrous conditions at 0 °C produces cycloalkyl adducts in good yields and short reaction times.

  描述了一种新的通用一锅法，用于在腈基前引入碳环。将 readily available 的芳基乙腈与氨基钾双(trimethylsilyl)处理，随后在无水条件下于0 °C的四氢呋喃中与α,ω-二溴或二氯烷烃进行烷基化，可以在短反应时间内以良好的产率生成环烷基附加物。
