  The potential rewarding and reinforcing effects of the substituted benzofurans 2-EAPB and 5-EAPB in rodents

  摘要：

  Accounts regarding the use of novel psychoactive substances continue to escalate annually. These include reports on substituted benzofurans (SBs), such as 1-(1-benzofuran-2-yl)-N-ethylpropan-2-amine (2-EAPB) and 1-(1-benzofuran-5-yl)-N-ethylpropan-2-amine (5-EAPB). Reports on the deaths and adverse consequences from the use of SBs warrant the investigation of their mechanism, possibly predicting the effects of similar compounds. Accordingly, we investigated the possible rewarding and reinforcing effects of 2-EAPB and 5-EAPB through conditioned place preference (CPP), self-administration, and locomotor sensitization tests. We also determined the possible influence of 2-EAPB and 5-EAPB administration on dopamine- and plasticity-related proteins in the nucleus accumbens and ventral tegmental area. 2-EAPB and 5-EAPB induced CPP at different doses and were self-administered by rats. Only 5-EAPB induced locomotor sensitization in mice. 2-EAPB and 5-EAPB did not alter the expressions of dopamine D1 and D2 receptors in the nucleus accumbens, nor changed tyrosine hydroxylase and dopamine transporter expressions in the ventral tegmental area. Both 2-EAPB and 5-EAPB enhanced deltaFosB, but not transcription factor cyclic AMP-response-element binding protein and brain-derived neurotrophic factor in the nucleus accumbens. Hence, the potential rewarding and reinforcing effects on rodents induced by 2-EAPB and 5-EAPB may possibly be associated with alterations in other neurotransmitter systems (besides mesolimbic) and/or neuro-plastic modifications.

  日期：2017.6

  cellulose‐based chiral stationary phase were achieved particularly with propane‐2‐ol and a mixture of isopropylamine and trifluoroacetic acid as organic modifier and additive to CO2, respectively. Methanol and basic additive isopropylamine were preferred on amylose‐based chiral stationary phase. The complementary enantioselectivity of the cellulose‐ and amylose‐based chiral stationary phases allows separation

  enantiomers may differ in their pharmacological effect. The aim of this study was to test a novel HPLC column for the enantioseparation of a set of 112 NPS coming from different chemical groups and collected by internet purchases during the years 2010–2018. The CSP, namely Lux® 5 μm i‐Amylose‐1, LC Column 250 x 4.6 mm, was run in normal phase mode under isocratic conditions, UV detection was performed

  这些术语背后隐藏着浴盐，熏蒸剂，清洁剂和空气清新剂，这些物质被算作“合法上限”。这些花哨的名字被用来装扮成合法的无害化合物，以规避市场营销的法律法规并增加销量。除了合成的经典非法药物（如苯丙胺，可卡因和摇头丸）以外，这些化合物的贸易（也称为新型精神活性物质（NPS））在当今并不罕见。在许多国家，NPS仍然不受药物管制。其中，有具有手性中心的兴奋剂，例如新的苯丙胺衍生物或卡西酮。关于两种可能的对映异构体的药理作用可能不同的事实知之甚少。这项研究的目的是测试一种新颖的HPLC色谱柱，该色谱柱用于对映分离2010年至2018年间通过互联网购买的来自不同化学族的112种NPS。CSP，即Lux®5μmi-Amylose-1，LC色谱柱250 x 4.6 mm，在等度条件下以正相模式运行，在245 nm和230 nm处进行UV检测，进样量为10μl，流速为为1毫升/分钟。使用由正己烷/异丙醇/二乙胺（90：10：0

Enantioresolution was achieved by simply adding native β‐cyclodextrin, acetyl‐β‐cyclodextrin, 2‐hydroxypropyl‐β‐cyclodextrin, or carboxymethyl‐β‐cyclodextrin as chiral selector additives to the background electrolyte.

  除了滥用众所周知的非法药物外，消费者还发现了新的合成化合物，它们具有相似的作用，但化学结构发生了微小变化。最初，创建这些所谓的新型精神活性物质（NPS）是为了规避因滥用毒品而引起的起诉法。在过去的十年中，此类化合物世代相传，最流行的化合物是合成的甲基吡啶酮衍生物，称为甲氧麻黄酮。卡西酮在结构上与苯丙胺有关；迄今为止，已经合成了120多种全新的衍生物，并通过Internet进行了交易。卡西酮具有手性中心。然而，关于其对映体的药理学知之甚少。但是，NPS还包含其他手性化合物，例如苯丙胺衍生物，氯胺酮，2-（氨基丙基）苯并呋喃，和吩啶。在我们的项目继续中，以前介绍的一种廉价，易于执行的手性毛细管电泳区分离卡西酮的方法已扩展到上述化合物类别。通过将天然β-环糊精，乙酰基-β-环糊精，2-羟丙基-β-环糊精或羧甲基-β-环糊精作为手性选择剂添加到背景电解质中，即可实现对映体拆分。51个手性NPS用作
