  Chronobiotic activity of N-[2-(2,7-dimethoxyfluoren-9-yl)ethyl]-propanamide. Synthesis and melatonergic pharmacology of fluoren-9-ylethyl amides

  摘要：

  A series of fluoren-9-yl ethyl amides (2) were synthesized and evaluated for human melatonin MT1 and MT2 receptor binding. N-[2-(2,7-dimethoxyfluoren-9-yl)ethyl]propanamide (2b) was selected and evaluated in functional assays measuring intrinsic activity at the human MT1 and MT2 receptors and demonstrated full agonism at both receptors. The chronobiotic properties of 2b were demonstrated in both acute and chronic rat models where 2b produced an acute phase advance of 32 min at 1 mg/kg and chronically entrained free-running rats with a mean effective dose of 0.23 mg/kg. Compound 2b is significantly less efficacious than melatonin in constricting human coronary artery. (C) 2004 Elsevier Ltd. All rights reserved.

  In the presence of catalytic [IrCp*Cl2}2] and Ag2CO3, Li2CO3 as the base, and acetone as the solvent, benzoic acids react with arenediazonium salts to give the corresponding diaryl‐2‐carboxylates under mild conditions. This CH arylation process is generally applicable to diversely substituted substrates, ranging from extremely electron‐rich to electron‐poor derivatives. The carboxylate directing

  在催化[IrCp * Cl 2 } 2 ]和Ag 2 CO 3，Li 2 CO 3为碱，丙酮为溶剂的情况下，苯甲酸与槟榔重氮盐反应生成相应的二芳基-2-羧酸盐温和的条件。这种CH芳基化过程通常适用于各种取代的底物，范围从极富电子的至贫电子的衍生物。羧酸根导向基团是广泛可得的，可以无痕地除去或用于进一步的衍生作用。通过使用重氮盐可实现与卤化物交叉偶联的正交性，即使存在碘取代基也可将其偶联。
