  Enhancing a CH−π Interaction to Increase the Affinity for 5-HT_1A Receptors

  摘要：

  An electrostatic interaction related to a favorable position of the distal phenyl ring and a phenylalanine residue in the binding pocket would explain the higher 5-HT1A affinity of a 4-phenyl-1,2,3,6-tetrahydropyridine (THP) analogue compared to the corresponding 4-phenylpiperazine analogue. To explore a possible reinforcement of this interaction to increase the affinity for 5-HT1A receptors, different 4-substituted-phenyl analogues were synthesized and tested. The most important increase of affinity is obtained with two electron-donating methyl groups in positions 3 and 5.

  ZM241385衍生物在人腺苷A2A受体上的结合动力学

  摘要：

  经典药物的设计和开发主要依赖于亲和力或效价驱动的结构-活性关系（SAR）。迄今为止，给定化合物的结合动力学已被很大程度上忽略，其重要性现在越来越被人们所认识。在本研究中，除了对腺苷A 2A受体（A 2A R）进行传统的SAR分析外，我们还进行了广泛的结构动力学关系（SKR）研究。由24 A 2A R化合物组成的化合物，所有三唑三嗪衍生物均类似于原型拮抗剂ZM241385（4-（2-（（7-氨基-2-（呋喃-2-基）-[1,2,4]三唑[1， 5一] [1,3,5] triazin-5-基）氨基）乙基）苯酚）在亲和力上仅显示微小差异，尽管它们与受体的解离速率差异很大。我们相信，像我们对A 2A R所做的那样，SKR和SAR分析的这种结合对于G蛋白偶联受体的超家族将具有普遍的重要性，因为它可以作为调整配体之间相互作用的新策略和受体。

• Benzyne‐Induced Ring Opening Reactions of DABCO: Synthesis of 1,4‐Disubstituted Piperazines and Piperidines

  strategies for its synthesis to date have required multistep methods and have been very limited, such as the use of SNAr‐type reactions. Herein, we describe a synthetic methodology employing benzynes, 1,4‐diazabicyclo(2.2.2)octane (DABCO), and nitrogen nucleophiles to access these privileged organic compounds. The established protocol proved to be a transition‐metal‐free, mild reaction that proceeded via

  2-（4-苯基哌嗪-1-基）乙-1-胺支架是结构上重要的基序，在药物和药物化学中经常出现。尽管该部分具有重要意义，但迄今为止，其合成的一般策略仍需要多步方法，并且非常局限，例如使用S N Ar型反应。在这里，我们描述了一种合成方法，该方法使用苯炔，1,4-二氮杂双环（2.2.2）辛烷（DABCO）和氮亲核试剂来访问这些特权有机化合物。业已证明的既定规程是无过渡金属的轻度反应，其反应是通过由苯甲酸和DABCO形成的季铵盐进行的。
• Chemical Modifications on 4-Arylpiperazine-Ethyl Carboxamide Derivatives Differentially Modulate Affinity for 5-HT1A, D4.2, and α2A Receptors: Synthesis and In Vitro Radioligand Binding Studies

  A series of substituted 4-aryl-piperazine-ethyl heteroarylcarboxamides were prepared and tested in in vitro radioligand binding studies. The presence of a quinoxaline has a favourable impact in terms of serotonin 5-HT1A versus dopamine D4.2 receptor selectivity. Compounds with a 3-CF3 group at the distal phenyl ring are the most effective in terms of affinity and selectivity for 5-HT1A versus D4.2 receptors. A 4-phenyl-1,2,3,6-tetrahydropyridine in place of the corresponding 4-phenyl-piperazine side chain is also favourable not only for the affinity for 5-HT1A and D4.2 receptors but also in some cases for α 2A-adrenoceptors.

  我们制备了一系列取代的 4-芳基哌嗪-乙基杂芳基羧酰胺，并在体外放射性配体结合研究中进行了测试。喹喔啉的存在对血清素 5-HT1A 与多巴胺 D4.2 受体的选择性具有有利影响。就对 5-HT1A 受体和 D4.2 受体的亲和力和选择性而言，远端苯环上带有 3-CF3 基团的化合物最为有效。用 4-苯基-1,2,3,6-四氢吡啶取代相应的 4-苯基-哌嗪侧链也不仅有利于提高对 5-HT1A 和 D4.2 受体的亲和力，而且在某些情况下还有利于提高对 α 2A 肾上腺素受体的亲和力。

  日期：2004.8.1

  A small molecule library of piperazinylalkylisoxazole derivatives containing about 600 compounds was designed, synthesized and evaluated for blocking effects on T-type Ca2+ channel. Several ligands were identified to possess high inhibitory activity against the T-type Ca2+ channel. The compound 21 with trifluoromethyl substituents at C-3-position of phenyl group (W) and C-2-position of phenyl group (R-2) showed the highest inhibitory activity with IC50 value of 1.02 muM, which is comparable to that of mibefradil.

• Pharmacophore-based design, synthesis, biological evaluation, and 3D-QSAR studies of aryl-piperazines as α1-adrenoceptor antagonists
  作者：Min-Yong Li、Hao Fang、Lin Xia

  DOI：10.1016/j.bmcl.2005.05.003

  日期：2005.7

  Phenyl-piperazines were designed and synthesized based on pharmacophore for uro-selective alpha(1)-adrenoceptor antagonists and 3D chemical database searching. Within this series, three compounds, 2, 3, and 13, showed similar or better alpha(1)-AR antagonistic activity compared with prazosin. The 3D-QSAR study of these compounds may provide useful information for the development of novel aryl-piperazines as uro-selective alpha(1)-adrenoceptor antagonists, which can be used for the treatment of BPH with fewer side effects.
