  Synthesis and evaluation of arylpiperazine-reverse amides as biased dopamine D3 receptor ligands

  摘要：

  The dopamine D3 receptor (D3R) preferential ligands have been universally adopted as a strategy for the treatment of drug addiction and other neuropsychiatric disorders due to fewer side effects. However, the high sequence homology between D3R and the D2 receptor (D2R) challenges the development of D3R-biased compounds. Herein, we design and synthesize a novel series of reverse amide-piperazine hybrid ligands and evaluate their biological affinities in vitro. Compound 4d was found to be the most potent D3R-selective ligand among these hybrid derivatives. Molecular modeling revealed that extracellular loop 1 (EL1) and loop 2 (EL2) of D3R together likely contribute to D3R selectivity over D2R. In particular, Gly94 in EL1 of D3R may act as a molecular determinant for D3R specificity. (C) 2015 Elsevier Ltd. All rights reserved.

  设计，合成和评估作为多巴胺D 3受体激动剂的双芳基哌嗪-邻苯二甲酰亚胺†

  摘要：

  多巴胺D 3受体（D 3 R）是公认的治疗神经系统疾病和神经精神疾病的治疗靶标。特别地，已经验证了可以消除与多巴胺D 2受体（D 2 R）治疗剂相关的副作用的D 3 R选择性配体。但是，信号通路的高度同源性以及D 2 R和D 3 R之间的序列相似性使D 3 R选择性配体的开发具有挑战性。在本文中，我们基于片段和分子对接启发设计，设计并合成了一系列哌嗪-邻苯二甲酰亚胺双位配体。化合物9i在这些双位配体中，被鉴定为最有选择性的D 3 R配体。与参考化合物1和2相比，其选择性分别提高了9倍和2倍，并且比化合物2的效价高21倍。分子对接表明亮氨酸的取向2.64和Phe 7.39和在螺旋的结填料可能影响d特异性3 R经由d 2 R.功能评价揭示，d 3 R-选择性配体9i中在显示亚皮摩尔激动剂活性d 3与喹吡罗相比，R的效价提高了199倍。这些结果可能对双主题化合物作为选择性D 3 R配体的基于片段的设计有用。

In this study, homologation and bioisosterism techniques have been used in the designing of new 1,4-disubstituted piperazines and piperidines. These derivatives were synthesized and evaluated as potential triple reuptake inhibitors for studying the structure-activity relationships. The most advanced compound, 1-(4-(5-

  单胺转运蛋白调节着单胺神经递质的浓度，这对于重要的生理过程至关重要，其功能障碍会导致多种中枢神经系统疾病。目前，单胺转运蛋白似乎是这些疾病管理中的潜在靶标。在这项研究中，同源性和生物立体异构技术已被用于设计新的1,4-二取代哌嗪和哌啶。这些衍生物被合成并评估为潜在的三重再摄取抑制剂，用于研究结构-活性关系。最先进的化合物1-（4-（5-苯甲酰基-1H-四唑-1-基）丁基）-4-（3-苯丙基）哌嗪（2i）在体外测试中能够抑制单胺神经递质的再摄取（对于5-HT，IC50 = 158.7nM，对于NE，IC50 = 99nM，对于DA，IC50 = 97.5nM）。

  In the search for potent dual norepinephrine and dopamine reuptake inhibitors, several substituted arylpiperazine–tetrazoles were designed, synthesized and evaluated for their neurotransmitter reuptake inhibitory activities. Various derivatives exhibited selective and strong neurotransmitter reuptake inhibitory activity. In particular, compounds with a three-carbon linker displayed selective and stronger

  The limitations of established serotonin (5-hydroxytryptamine, 5-HT) and norepinephrine (NE) reuptake inhibitors necessitate the development of safer and more effective therapeutic agents. Based on the structures of 4-benzylpiperidine carboxamides and trazodone, arylpiperazine–benzylpiperidines with chemical scaffolds different from those of marketed drugs were designed, synthesized, and evaluated

  既定的5-羟色胺（5-羟色胺，5-HT）和去甲肾上腺素（NE）再摄取抑制剂的局限性需要开发更安全，更有效的治疗剂。根据4-苄基哌啶羧酰胺和曲唑酮的结构，设计，合成和评估化学支架与市售药物不同的芳基哌嗪-苄基哌啶，并评估其对神经递质再摄取的抑制活性。大多数合成化合物显示出比5-HT再摄取抑制更大的NE。其活性甚至大于标准药物盐酸文拉法辛。具有三碳连接基的衍生物表现出比具有二碳连接基的衍生物更好的活性。在新合成的化合物中，第2d表现出最强的神经递质再摄取抑制作用（ NE的IC 50 = 0.38μM，5-HT的IC 50 = 1.18μM）。生物学活性数据表明，芳基哌嗪-苄基哌啶具有开发作为治疗神经精神病和神经退行性疾病的新型治疗剂的潜力。
