  Synthesis and pharmacological evaluation of novel N-aryl-3,4-dihydro-1′H-spiro[chromene-2,4′-piperidine]-1′-carboxamides as TRPM8 antagonists

  摘要：

  A novel series of N-aryl-3,4-dihydro-1'H-spiro[chromene-2,4'-piperidine]-1'-carboxamides was identified as transient receptor potential melastatin 8 (TRPM8) channel blockers through analogue-based rational design, synthesis and screening. Details of the synthesis, effect of aryl groups and their substituents on in-vitro potency were studied. The effects of selected functional groups on the 4-position of the chromene ring were also studied, which showed interesting results. The 4-hydroxy derivatives showed excellent potency and selectivity. Optical resolution and screening of alcohols revealed that (R)-(-)-isomers were in general more potent than the corresponding (S)-(+)-isomers. The isomer (R)-(-)-10e (IC50: 8.9 nM) showed a good pharmacokinetic profile upon oral dosing at 10 mg/kg in Sprague-Dawley (SD) rats. The compound (R)-(-)-10e also showed excellent efficacy in relevant rodent models of neuropathic pain. (C) 2013 Elsevier Ltd. All rights reserved.

  鉴定螺[色烯-2,4'-哌啶]作为有效、选择性和 Gq 偏向的 5-HT2C 受体部分激动剂

  摘要：

  基于我们之前的先导化合物1，通过结构修饰设计和合成了一系列螺哌啶，并通过细胞信号转导测定进行评估，以发现具有 G q偏向的 5-HT 2C受体 (5-HT 2C R) 选择性激动剂。螺哌啶的构效关系 (SAR) 研究发现螺[色烯-2,4′-哌啶]是一种新型 5-HT 2C R 选择性激动剂化学型。在这个新系列中，7-氯类似物8被确定为最有效和最具选择性的 5-HT 2C R 部分激动剂 ( E max = 71.09%)，EC 50值为 121.5 nM，并且没有观察到对 5-HT 2A的活性R 或 5-HT 2B R。此外，化合物8对 β-arrestin 没有表现出募集活性，并且在 10 μM 时表现出对 hERG 的低抑制作用。这些发现可能为开发更有效的 G q偏向 5-HT 2C R 部分激动剂作为有用的药理学工具化合物或潜在的候选药物铺平道路。

  Cyclization of the benzoylpiperidine in lead compound 2 generated a series of novel and highly potent spiropiperidine-based stearoyl-CoA desaturase (SCD)-1 inhibitors. Among them, 1'-6-[5-(pyridin-3-ylmethyl)-1,3,4-oxadiazol-2-yl]pyridazin-3-yl}-5-(trifluoromethyl)-3,4-dihydrospiro[chromene-2,4'-piperidine] (19) demonstrated the most powerful inhibitory activity against SCD-1, not only in vitro but also in vivo (C57BL/6 J mice). With regard to the pharmacological evaluation, 19 showed powerful reduction of the desaturation index in the plasma of C57BL/6 J mice on a non-fat diet after a 7-day oral administration (q.d.) without causing notable abnormalities in the eyes or skin up to the highest dose (3 mg/kg) in our preliminary analysis.

  On the basis of a spirocyclic ether screening lead, a series of acyclic sulfones have been identifed as high-affinity, selective 5-HT2A receptor antagonists. Bioavailability lacking in the parent, 1-(2-(2,4-difluorophenyl)ethyl)-4-(phenylsulfonyl)piperidine (12), was introduced by using stability toward rat liver microsomes as a predictor of bioavailability. By this means, the 4-cyano- and 4-carboxamidophenylsulfonyl derivatives 26 and 31 were identified as orally bioavailable, brain-penetrant analogues suitable for evaluation in animal models. Bioavailability was also attainable by N substitution leading to the N-phenacyl derivative 35. IKr activity detected through counterscreening was reduced to insignificant levels in vivo with the latter compound.
