  新型芳基哌嗪与作为血清素 5-HT1A/5-HT7 受体配体的柔性接头与部分约束接头

  摘要：

  合成了一系列具有灵活且部分受限的烷基接头的新型长链芳基哌嗪 (LCAP) 衍生物，并在体外作为潜在的血清素 5-HT1A 和 5-HT7 受体配体进行了研究。使用萘二甲酰亚胺和 2H-1,3-苯并恶嗪-2,4(3H)-二酮作为酰亚胺，以及 1-(2-甲氧基苯基)哌嗪 (o-OMe-PhP) 和 1 ,2,3,4-四氢异喹啉 (THIQ) 作为胺药效团。间隔结构的修改包括引入灵活的五亚甲基和六亚甲基链以及部分受限的间和对二甲苯基部分。一般而言，新化合物对 5-HT1A 的活性高于对 5-HT7 受体的活性，并且 o-OMe-PhP 衍生物比其各自的 THIQ 类似物表现出更高的亲和力。间隔修饰对观察到的体外活性几乎没有影响。在 o-OMe-PhP 系列中，除了含有间二甲苯基部分的配体的结合略有减少外，化合物对两种受体的效力没有实质性变化，而对于 THIQ 衍生物，具有明确的构效关系仅在化合物与

  The (2-methoxyphenyl) piperazine (MPP) was selected as the functional group and conjugated to dithiocarbamate through different spacers. A series of new MPP derivatives (MPPnDTC, n = 2–6) were synthesized and radiolabelled with 99mTc-nitrido core or 99mTc-tricarboxyl core as potential 5-HT1A receptor imaging agents. All the six 99mTc-labelled complexes were lipophilic and neutral. Biodistribution results showed that those radiotracers had moderate initial brain and hippocampus uptake. There have no significant relation was observed between the biological properties of these tracers with the length of its carbon chain. The radioactivity concentrations of hippocampus of 99mTcN-MPP2DTC, 99mTcN-MPP3DTC, 99mTcN-MPP4DTC, 99mTcN-MPP5DTC, 99mTcN-MPP6DTC and 99mTc(CO)3-MPP3DTC at 2 min post-injection time (p.i.) were 0.43, 1.15, 0.99, 1.04, 1.13 and 0.83 %ID/g, respectively.

  选择（2-甲氧基苯基）哌嗪（MPP）作为功能团，通过不同间隔基与二硫代氨基甲酸盐偶联。合成了一系列新的MPP衍生物（MPPnDTC，n = 2–6），并以99mTc-氮杂核或99mTc-三羧基核进行放射性标记，作为潜在的5-HT1A受体成像剂。所有六个99mTc标记的配合物都是亲脂性的和中性的。生物分布结果显示，这些放射性示踪剂在初始阶段具有适度的脑和海马体摄取。这些示踪剂的生物学特性与其碳链长度之间没有显著关系。99mTcN-MPP2DTC、99mTcN-MPP3DTC、99mTcN-MPP4DTC、99mTcN-MPP5DTC、99mTcN-MPP6DTC和99mTc(CO)3-MPP3DTC在注射后2分钟的海马体放射性浓度分别为0.43、1.15、0.99、1.04、1.13和0.83 %ID/g。

• N-(phthalimidoalkyl) derivatives of serotonergic agents: a common interaction at 5-HT1A serotonin binding sites?

  Several classes of agents are known to bind at central 5-HT1A serotonin sites In order to challenge the hypothesis that these agents bind in a relatively similar manner (i.e., share common aryl and terminal amine sites), we prepared N-(phthalimidobutyl) derivatives of examples of several such agents. With regard to arylpiperazines, we had previously shown that introduction of this functionality at the terminal amine is tolerated by the receptor and normally results in a significant (greater than 10-fold) enhancement in affinity. The results of the present study show that this bulky functionality is also tolerated by the receptor when incorporated into examples of all other major classes of 5-HT1A agents (e.g., 2-aminotetralin, phenylalklamine, indolylalkylamine, and (aryloxy)alkylamine derivatives). The length of the alkyl chain that separates the terminal amine from the phthalimido group is of major importance, and a four-carbon chain appears optimal. Alteration of the length of this chain can have a significant influence on affinity; decreasing the chain length from four to three carbon atoms can reduce affinity by an order of magnitude, and further shortening can have an even more pronounced effect.
• Synthesis and in vitro binding studies of piperazine-alkyl-naphthamides: Impact of homology and sulphonamide/carboxamide bioisosteric replacement on the affinity for 5-HT1A, α2A, D4.2, D3 and D2L receptors

  日期：2010.9

  A series of carboxamide and sulphonamide alkyl(ethyl to hexyl) piperazine analogues were prepared and tested for their affinity to bind to a range of receptors potentially involved in psychiatric disorders. These chemical modifications led us to explore the impact of homology and bioisosteric replacement of the amide group. All of these compounds possessed a high affinity for 5-HT1A receptors, irrespective of the size of the linker, the carboxamide derivative with a pentyl linker had the highest affinity for alpha(2A) receptor sites and also a high affinity for 5-HT1A and D3 receptors. The sulphonamide analogue with a hexyl linker possessed a high affinity for 5-HT1A, D4.2 and D3 receptors. (C) 2010 Elsevier Ltd. All rights reserved.
