  4-Heterocyclyl tetrahydropyridines as selective ligands for the human dopamine D4 receptor

  摘要：

  A series of 1,2,3,6-tetrahydropyridines 3 were synthesised, which resulted in selective high affinity dopamine Dq ligands. The SAR of heterocyclic replacements and aromatic substitution was investigated, leading to compounds of nanomolar binding affinity with excellent selectivity over both D-2 and D-3 receptors.

  A class of 1,2,3,6-tetrahydropyridine derivatives, substituted in the 4-position by a fused bicyclic heteroaromatic moiety and in the 1-position by an optionally substituted benzyl moiety, are ligands for dopamine receptor subtypes within the body, in particular the D.sub.4 subtype, and are therefore useful in the treatment and/or prevention of disorders of the dopamine system, in particular schizophrenia or depression.

  Diabetes is the primary cause of fatality and disability all over the world, in recent past, we have reported various classes of compounds as anti-glycating agents and we have also reported benzimidazole and benzothiazole derivatives as a potential class of anti-glycating agents. This encouraged us to evaluate the pyridinyl benzimidazole/pyridinyl benzothiazole derivatives 1-27 for yeast glucose uptake activity.

  In the present study, an equimolar mixture of pyridine carboxaldehyde derivatives (1 mmol) and sodium metabisulphite (1 mmol) in DMF (10 mL) was stirred for 10 to 15 min, followed by addition of o-phenylene diamine/2-aminothiophenol (1 mmol) into it and refluxed for 3 h. The progress of the reaction was monitored by TLC. After completion, the reaction mixture was poured into crushed ice. Precipitates were formed which were collected by filtration to produce compounds 1-27 in good yields. Recrystallization from methanol yielded pure crystals.

  Our present study showed that all compounds showed a varying degree of yeast glucose uptake activity in the range IC50 = 36.43-272.20 µM, compared to standard metronidazole (IC50 = 41.86 ± 0.09 µM). Compounds 5 (IC50 = 38.14 ± 0.17 µM), 6 (IC50 = 40.23 ± 0.20 µM), and 7 (IC50 = 36.43 ± 0.02 µM) showed an excellent yeast glucose uptake activity better than the standard.

  Pyridinyl benzimidazole/pyridinyl benzothiazole derivatives 1-27 were synthesized, structurally characterized, and evaluated for in vitro yeast glucose uptake activity. Compounds 5 (IC50 = 38.14 ± 0.17 µM), 6 (IC50 = 40.23 ± 0.20 µM), and 7 (IC50 = 36.43 ± 0.02 µM) demonstrated potent yeast glucose uptake activity as compared to standard metronidazole (IC50 = 41.86 ± 0.09 µM). This study identified a number of potential lead molecules which can be helpful in lowering the blood glucose level in hyperglycemia.

  背景：糖尿病是全球致死和致残的主要原因，最近，我们已报告各种类别的化合物作为抗糖基化剂，并且我们还报告苯并咪唑和苯并噻唑衍生物作为一种潜在的抗糖基化剂类。这激励我们评估吡啶基苯并咪唑/吡啶基苯并噻唑衍生物1-27对酵母葡萄糖摄取活性的作用。 方法：在本研究中，将吡啶羧醛衍生物（1 mmol）和亚硫酸钠（1 mmol）在DMF（10 mL）中等摩尔混合物搅拌10至15分钟，然后加入邻苯二胺/2-氨基硫酚（1 mmol）并回流3小时。通过薄层色谱监测反应进展。反应完成后，将反应混合物倒入碎冰中。形成沉淀，通过过滤收集，产生产率良好的化合物1-27。用甲醇再结晶得到纯晶体。 结果：我们的研究表明，所有化合物在酵母葡萄糖摄取活性范围内显示出不同程度的活性，IC50 = 36.43-272.20 µM，与标准甲硝唑（IC50 = 41.86 ± 0.09 µM）相比。化合物5（IC50 = 38.14 ± 0.17 µM）、6（IC50 = 40.23 ± 0.20 µM）和7（IC50 = 36.43 ± 0.02 µM）显示出优异的酵母葡萄糖摄取活性，优于标准物质。 结论：合成了吡啶基苯并咪唑/吡啶基苯并噻唑衍生物1-27，进行了结构表征，并评估了体外酵母葡萄糖摄取活性。化合物5（IC50 = 38.14 ± 0.17 µM）、6（IC50 = 40.23 ± 0.20 µM）和7（IC50 = 36.43 ± 0.02 µM）表现出强大的酵母葡萄糖摄取活性，与标准甲硝唑（IC50 = 41.86 ± 0.09 µM）相比。该研究确定了一系列潜在的先导分子，有助于降低高血糖水平。

  Benzoxazoles, benzothiazoles and benzimidazoles having substituents on the azole and benzene nuclei were synthesized evaluated for antifungal, insecticidal and herbicidal activities. It was found that benzimidazoles tended to exhibit antifungal activity while benzothiazoles tended to show herbicidal activity. Chloro, trifluoromethyl, methoxy and ethoxy groups at the 5 position were potent substituents, and the 2-pyridyl group at the 2 position is a common structural unit. Among several active derivatives, 7-chloro-2-(2-pyridyl) benzimidazole and 2-(2-pyridyl)-5-trifluoromethylbenzothiazole exhibited significant activity against Panonycus citri.
