  • Dual Nicotinic Acetylcholine Receptor α4β2 Antagonists/α7 Agonists: Synthesis, Docking Studies, and Pharmacological Evaluation of Tetrahydroisoquinolines and Tetrahydroisoquinolinium Salts

    We describe the synthesis of tetrahydroisoquinolines and tetrahydroisoquinolinium salts together with their pharmacological properties at various nicotinic acetylcholine receptors. In general, the compounds were α4β2 nAChR antagonists, with the tetrahydroisoquinolinium salts being more potent than the parent tetrahydroisoquinoline derivatives. The most potent α4β2 antagonist, 6c, exhibited submicromolar
    我们描述了四氢异喹啉盐和四氢异喹啉盐的合成以及它们在各种烟碱乙酰胆碱受体上的药理特性。通常,这些化合物是α4β2nAChR拮抗剂,四氢异喹啉盐比母体四氢异喹啉衍生物更有效。最有效的α4β2拮抗剂,6C,显示出亚微摩尔的结合ķ我和功能IC 50值和该受体在α4β4和α3β4nAChRs的高选择性。(S)-6c对映异构体在α4β2处基本上是无活性的,(R)-6cα4β2拮抗剂是比参考β2-nAChR拮抗剂DHβE稍微有效的α4β2拮抗剂。α4β2活性仅存在于(R)-对映异构体中的观察与对接研究完全一致。几种四氢异喹啉鎓盐也对α7nAChR表现出激动剂活性。体内初步评估显示,(R)-5c和(R)-6c在小鼠强迫游泳试验中均具有抗抑郁样作用,支持α4β2nAChR拮抗剂对该适应症的治疗潜力。

    1-arylmethyl-1,2,3,4-tetrahydro-2,2-dimethylisoquinolinium iodides with methanolic KOH gave stilbene derivatives, for example, (E)-N-22-[2-(phenyl)ethenyl]-4,5-dimethoxyphenyl}ethyl-N,N-dimethylamine. Photochemical electrocyclization of these stilbenes afforded the corresponding phenanthrene alkaloids/phenanthrene derivatives.

  • Methyl-Laudanosine: A New Pharmacological Tool to Investigate the Function of Small-Conductance Ca<sup>2+</sup>-Activated K<sup>+</sup>Channels
    作者:Jacqueline Scuvee-Moreau、Jean-François Liegeois、Laurent Massotte、Vincent Seutin
    DOI:10.1124/jpet.302.3.1176

    Small-conductance Ca2+-activated K+ channels (SK channels) underlie the prolonged postspike afterhyperpolarization (AHP) observed in many central neurons and play an important role in modulating neuronal activity. However, a lack of specific and reversible blockers of these channels hampers their study in various experimental conditions. Because previous work has shown that bicuculline salts block these channels, we examined whether related alkaloids, namely laudanosine quaternary derivatives, would produce similar effects. Intracellular recordings were performed on rat midbrain dopaminergic neurons and hippocampus CA1 pyramidal cells. Binding experiments were performed on rat cerebral cortex membranes. Laudanosine, methyl-laudanosine, and ethyl-laudanosine blocked the apamin-sensitive AHP of dopaminergic neurons with mean IC50 values of 152, 15, and 47 μM, respectively. The benzyl and butyl derivatives were less potent. Methyl-laudanosine had no effect on the Ih current, action potential parameters, or membrane resistance of dopaminergic cells, or on the decrease in input resistance induced by muscimol, indicating a lack of antagonism at GABAA receptors. Interestingly, 100 μM methyl-laudanosine induced a significant increase in spiking frequency of dopaminergic neurons but not of CA1 pyramidal cells, suggesting the possibility of regional selectivity. Binding experiments on laudanosine derivatives were in good agreement with electrophysiological data. Moreover, methyl-laudanosine has no affinity for voltage-gated potassium channels, and its affinity for SK channels (IC504 μM) is superior to its affinity for muscarinic (IC50114 μM) and neuronal nicotinic (IC50 ≥367 μM) receptors . Methyl-laudanosine may be a valuable pharmacological tool to investigate the role of SK channels in various experimental models.
    小传导 Ca2+ 激活 K+ 通道(SK 通道)是在许多中枢神经元中观察到的尖峰后超极化(AHP)延长的基础,在调节神经元活动中发挥着重要作用。然而,这些通道缺乏特异性和可逆性的阻断剂,阻碍了在各种实验条件下对它们的研究。由于之前的研究表明双丘氨酸盐类能阻断这些通道,我们研究了相关生物碱(即月桂苷四元衍生物)是否会产生类似的效果。我们在大鼠中脑多巴胺能神经元和海马 CA1 锥体细胞上进行了细胞内记录。在大鼠大脑皮层膜上进行了结合实验。鸦胆子碱、甲基鸦胆子碱和乙基鸦胆子碱阻断了多巴胺能神经元对阿帕明敏感的AHP,其平均IC50值分别为152、15和47 μM。苄基和丁基衍生物的效力较弱。甲基-月桂苷对多巴胺能细胞的 Ih 电流、动作电位参数或膜电阻,或对 muscimol 引起的输入电阻下降没有影响,这表明它对 GABAA 受体缺乏拮抗作用。有趣的是,100 μM 甲基-月桂苷能显著增加多巴胺能神经元的尖峰频率,但不能增加 CA1 锥体细胞的尖峰频率,这表明可能存在区域选择性。月桂苷衍生物的结合实验与电生理数据十分吻合。此外,甲基-月桂苷对电压门控钾通道没有亲和力,而它对 SK 通道的亲和力(IC504 μM)优于它对毒蕈碱受体(IC50114 μM)和神经元烟碱受体(IC50 ≥367 μM)的亲和力。甲基-鸦片甙可能是研究 SK 通道在各种实验模型中作用的一种有价值的药理学工具。
