  Favourable involvement of α2A-adrenoreceptor antagonism in the I2-imidazoline binding sites-mediated morphine analgesia enhancement

  摘要：

  Aim of the present study was to obtain novel alpha(2)-adrenoreceptor (alpha(2)-AR) antagonists, possibly endowed with subtype-selectivity. Therefore, inspired by the non subtype-selective alpha(2)-AR antagonist idazoxan, we designed 1,4-dioxane derivatives bearing an aromatic area in position 5 or 6 and the imidazoline nucleus in position 2. Among the novel molecules 1-6, compound 2, with a trans stereochemical relationship between 5-phenyl and 2-imidazoline groups, was able to antagonize the sole alpha(2A)-subtype. Moreover, 2 showed an affinity at I-2-imidazoline binding sites (I-2-IBS) comparable to that at alpha(2A)-AR. In in vivo studies 2 strongly increased morphine analgesia. This interesting behaviour appeared to be induced by the favourable involvement of alpha(2A)-AR antagonism in the I-2-IBS-mediated morphine analgesia enhancement. (C) 2012 Elsevier Ltd.

  Structure−Activity Relationships in 1,4-Benzodioxan-Related Compounds. 9. From 1,4-Benzodioxane to 1,4-Dioxane Ring as a Promising Template of Novel α_1D-Adrenoreceptor Antagonists, 5-HT_1A Full Agonists, and Cytotoxic Agents

  摘要：

  Novel 1,4-dioxane compounds structurally related to WB 4101 (1) were prepared in order to investigate the possibility that the quite planar 1,4-benzodioxane template of I might be replaced by the less conformationally constrained 1,4-dioxane ring. The biological profiles of the new compounds were assessed using binding assays at human cloned alpha(1)-adrenoreceptor (alpha(1)-AR) subtypes and 5-HT1A receptors, expressed in Chinese hamster ovary and HeLa cell membranes, respectively, and by functional experiments in isolated rat vas deferens (alpha(1A)), spleen (alpha(1B)), and aorta (alpha(1D)). Moreover, the cytotoxic effects of the novel compounds were determined in PC-3 prostate cancer cells. The results showed that the properly substituted 1,4-dioxane nucleus proved to be a suitable scaffold for selective alpha(1D)-AR antagonists (compound 14), potential anticancer agents (compound 13), and full 5-HT1A receptor agonists (compound 15). In particular, compound 15 may represent a novel lead in the development of highly potent 5-HT1A receptor full agonists useful as antidepressant and neuroprotective agents.

  multitarget behavior has been highlighted for the 5,5-diphenyl-1,4-dioxane and 1,4-benzodioxane derivatives 6 and 9, respectively, which displayed potent D2R antagonism, 5-HT1AR and D4R agonism, as well as potent D3R partial agonism. They also behaved as low-potency 5-HT2AR antagonists and 5-HT2CR partial agonists. Such a profile might be a promising starting point for the discovery of novel antipsychotic agents

  在寻找靶向多巴胺 D 3受体 (D 3 R) 的新型双位化合物时，N -(2,3-二氯苯基)哌嗪核（主要药效团）已与 6,6- 或 5,5-二苯基连接-1,4-二恶烷-2-甲酰胺或 1,4-苯并二恶烷-2-甲酰胺支架（二级药效团）由未取代或 3-F-/3-OH-取代的丁基链构成。这种支架杂交策略导致发现了可能对中枢神经系统疾病有用的有效的 D 3 R 选择性或多靶标配体。特别地，6,6-二苯基-1,4-二恶烷衍生物3显示出D 3R 优先分布，而 5,5-二苯基-1,4-二恶烷和 1,4-苯二恶烷衍生物6和9分别显示出有效的 D 2 R 拮抗作用，5-HT 的多靶点行为1A R 和 D 4 R 激动，以及有效的 D 3 R 部分激动。它们还表现为低效 5-HT 2A R 拮抗剂和 5-HT 2C R 部分激动剂。这样的概况可能是发现新型抗精神病药物的一个有希望的起点。
