    5-Aryl-1H-tetrazoles (1–24) were synthesized and screened for their xanthine oxidase (XO) inhibitory activity using allopurinol as standard inhibitor (IC50 = 2.0 ± 0.01 µM). Six compounds 3, 4, 5, 9, 21, and 24 exhibited significant to weak activities with IC50 values in the range of 7.4–174.2 µM. Active compounds were further subjected to kinetic and molecular docking studies to deduce their modes
    合成了5-芳基-1 H-四唑(1 – 24),并使用别嘌呤醇作为标准抑制剂(IC 50  = 2.0±0.01 µM),筛选了它们的黄嘌呤氧化酶(XO)抑制活性。六种化合物3,4,5,9,21,和24显示出显著弱活动带IC 50值在7.4–174.2 µM的范围内。进一步对活性化合物进行动力学和分子对接研究,以推导其抑制方式,并分别在原子平上研究其与蛋白质(XO)的相互作用。有趣的是,所有这些化合物都显示出竞争性的抑制方式。对接研究确定了配体与受体蛋白(XO)之间的几种重要相互作用。这些相互作用中的一些类似于XO的临床抑制剂(allopurinol和非布索坦)所表现出的相互作用。这项研究确定了5-芳基-1 H-四唑是一类新的黄嘌呤氧化酶抑制剂,值得进一步研究以治疗高尿酸血症和痛风。

    Tetrazoles are incredibly useful organic molecules with a wide range of applications from medicinal chemistry as carboxylic acid isosteres to high energy density materials in space research. In an effort to develop an easy protocol for the synthesis of tetrazoles from nitriles, we used nano‐Ag‐TiO2 as an efficient heterogeneous catalyst for the reaction of various nitriles and sodium azide to afford

  • A Novel and Efficient Nano Alumina Based Cu (II) Catalyst for Three- Component Synthesis of 5-Substituted-1H-Tetrazoles

    :

    Tetrazoles as one of the most important synthetic heterocyclic compounds have so many applications in organic chemistry, the photographic industry, coordination chemistry, explosives and in particular, medicinal chemistry. Numerous methods have been reported in the literature for synthesis of tetrazoles, but much of them have some drawbacks including the use of strong Lewis acids or expensive and toxic metals and employment of acidic media. Azides may react with acids to yield toxic and flammable HN3 gas. Furthermore, many methods used high polar solvents such as DMF at high temperatures and very tedious work-up. Heterogeneous catalysts are preferred because of owing to easy handling, safety, recoverability and reusability. Catalyst separation and recycling is highly desirable because catalysts are often very expensive. On the other hand, in spite of higher reactivity and selectivity of homogeneous catalysts, the difficulty of separating them from the reaction medium can lead to the problem of reusing the catalyst. Also, most homogeneous catalysts are thermally unstable. To benefit advantages of both types of catalysts, one solution is using nanoparticles. Their higher surface area is the advantages of nanoparticles, which allows them to enhance the reaction rate. Many commercially important catalysts include active nanoparticles spread on high area oxide supports. Such catalysts are highly complex materials that are optimized to work for plenty of turnovers at high reaction rates and with high selectivity. Aldehyde (1 mmol), hydroxylamine hydrochloride (0.10 mg, 1.5 mmol), sodium azide (0.10 g, 1.5 mmol), distilled water (5 mL) and nano Al2O3@PCH-Cu (II) (0.01g, 1.04% mol) were added to round bottom flask (25 mL) and stirred at room temperature. After the completion of the reaction, water (10 mL) was added into reaction mixture and filtered. Excess sodium azide and hydroxylamine hydrochloride are dissolved in water and the catalyst remains on the filter. Extraction of product with diethyl ether (3×10 mL) and then evaporation of ether afforded the product. The product was recrystallized using hot ethanol to obtain pure product. We synthesized a novel, stable, highly reactive and efficient nano-sized heterogeneous catalyst (nano Al2O3@PCH-Cu (II)). We characterized it by FT-IR, ICP, SEM, TGA and EDX analysis. This catalyst was used for the efficient one-pot three-component synthesis of 5-substituted-1H-tetrazoles. An one-pot three-component synthesis of 5-substituted-1Htetrazoles is conducted, a reaction between various benzaldehydes, hydroxyl amine hydrochloride and sodium azide in the presence of a novel and highly efficient nano alumina supported poly(carboxylic acid hydrazide) Cu(II) complex, nano Al2O3@PCH-Cu(II), as heterogeneous catalyst in H2O at room temperature. This method has very mild reaction conditions as well as the advantages of easy separation and reusability of the catalyst, very short reaction times, high yields and using H2O as green solvent. Furthermore, using this method very high TON and TOF values obtained for all isolated products.

    四唑是最重要的合成杂环化合物之一,在有机化学、摄影工业、配位化学、爆炸物和特别是药物化学中有许多应用。文献中已经报道了许多合成四唑的方法,但其中许多方法存在一些缺点,包括使用强Lewis酸或昂贵和有毒的属,以及使用酸性介质。另外,叠氮化物可能与酸反应产生有毒和易燃的HN3气体。此外,许多方法使用高极性溶剂,如DMF,在高温下非常繁琐。异质催化剂更受欢迎,因为易于处理、安全、可回收和可重复使用。催化剂的分离和循环利用非常理想,因为催化剂通常非常昂贵。另一方面,尽管均相催化剂的反应活性和选择性更高,但难以从反应介质中分离它们可能导致催化剂重复使用的问题。此外,大多数均相催化剂是热不稳定的。为了获得两种催化剂的优点,一种解决方案是使用纳米颗粒。纳米颗粒的高表面积是其优点,可以增强反应速率。许多商业重要的催化剂包括散布在高面积氧化物支撑物上的活性纳米颗粒。这种催化剂是高度复杂的材料,经过优化,可以在高反应速率和高选择性下进行大量的反应。 在圆底烧瓶(25 mL)中加入醛(1 mmol)、羟酸盐(0.10 mg,1.5 mmol)、叠氮(0.10 g,1.5 mmol)、蒸馏(5 mL)和纳米Al2O3@PCH-Cu(II)(0.01 g,1.04%mol),并在室温下搅拌。反应完成后,加入(10 mL)到反应混合物中并过滤。过量的叠氮和羟酸盐溶解在中,催化剂留在过滤器上。用乙醚(3×10 mL)提取产物,然后蒸发乙醚得到产物。用热乙醇重结晶得到纯品。 我们合成了一种新型、稳定、高反应性和高效的纳米级异质催化剂(纳米Al2O3@PCH-Cu(II))。我们通过FT-IR、ICP、SEM、TGA和EDX分析对其进行了表征。该催化剂用于5-取代-1H-四唑的高效一锅法三组分合成。在中,在室温下,使用新型和高效的纳米氧化铝支撑的聚(羧酸)Cu(II)复合物,纳米Al2O3@PCH-Cu(II)作为异质催化剂,反应各种苯甲醛、羟酸盐和叠氮。该方法具有非常温和的反应条件,易于分离和重复使用催化剂,反应时间非常短,产率高,并使用H2O作为绿色溶剂。此外,使用此方法获得了所有分离产品的非常高的TON和TOF值。
