    摘要:
    聚氢喹啉 (PHQ) 是 1,4-二氢吡啶的不对称 Hantzsch 衍生物,具有多种生物应用。在这项工作中,通过四组分反应 (4CR)以良好的产率合成了来自不同脂肪酸和脂肪醇原料的新型脂肪 2-和 3-取代 PHQ 衍生物。使用三种不同的抗氧化方法研究了脂肪 PHQ 的抗氧化活性。实验表明,源自2-硝基苯甲醛和脂肪棕榈酸(C16:0)和油酸(C18:1)链的化合物表现出更好的抗氧化活性。这表明,芳环中的邻位NO 2基团与PHQ核心中脂肪链的插入相结合有助于抗氧化活性。然而,在所有测试的脂肪PHQ中,源自油醇和2-硝基苯甲醛的脂肪2-取代化合物表现出最高的抗氧化活性(EC 50,2.11–4.69 μM),这与抗氧化剂标准丁基羟基甲苯的抗氧化活性相似( EC 50 , 1.98–6.47 μM) 和维生素 E (EC 50 , 1.19–5.88 μM)。此外,这种亲脂性化合物表现出比抗高血压药物硝苯地平更高的抗氧化活性(EC

    The 1,3‐dicarbonyl compounds are important building blocks to obtain products with various biological activities and technological applications. In this work, we used a simple transesterification method to develop fatty acetoacetates in a solvent‐free medium using a green catalyst, sulfamic acid (NH2SO3H), under microwave irradiation. The experimental results demonstrate good yields in a short reaction

The DHPs were tested for antioxidant activity using three different methods. The insertion of a long chain into the DHP core contributed to antioxidant potential, and compounds derived from nitro aldehydes have better antioxidant potential than

  • Organocatalytic Synthesis and Antitumor Activity of Novel 1,2,3-triazoles Derived from Fatty β-ketoesters
    作者:Fabiana K. Seixas、Diego Alves、Carolina B. Gomes、Caroline L. Corrêa、Diego C. Cabrera、Marcelo G. M. D'Oca、Martha Ruiz、Tiago Collares、Lucielli Savegnago
    DOI:10.2174/1573406417666210921143646
    日期:2022.5
    Background:

    Developing methods to synthesize highly functionalized and complex 1,2,3-triazoles from various combinations of substrates remains a significant challenge in organic synthesis. Thus, to the best of our knowledge, an organocatalytic approach to synthesize 1,2,3-triazoles derived from fatty acids has not been explored.

    Objective:

    In this sense, we describe here the organocatalyzed synthesis and preliminary results of antitumor and cytotoxic activity of a range of 1,2,3-triazoles derived from fatty esters.

    Methods:

    To synthesize 1,2,3-triazoles 3 derived from fatty β-ketoesters, we performed the reaction of appropriate aryl azides 2a-j with β-ketoesters 1a-c in the presence of 5 mol% of DBU using DMSO as a solvent at 70 °C for 24 h. The viability of 5637 cells was determined by measuring the reduction of soluble MTT to water-insoluble formazan. The IC50 concentration that inhibits 50% of cell growth and the results were obtained by at least three independent experiments in triplicate for each test.

    Results:

    Through enolate-mediated organocatalysis, 1,2,3-triazoles 3 derived from fatty β-ketoesters were synthesized in moderate to excellent yields by reacting fatty esters 1 with aryl azides 2 in the presence of a catalytic amount of 1,8-diazabicyclo[5.4.0]undec-7-ene (5 mol%). All compounds derived from palmitic acetoacetate 1a were evaluated regarding induced cytotoxicity in vitro in a human bladder cancer cell line, and compounds 3a, 3d, 3e, and 3g were shown to be promising alternatives for bladder cancer treatment and presented the lowest inhibitory concentration of IC50.

    Conclusion:

    We described a synthetic procedure to prepare 1,2,3-triazoles derived from fatty β-ketoesters by DBU-catalyzed 1,3-dipolar cycloaddition reactions of fatty esters with different aryl azides. Compounds derived from palmitic acetoacetate were screened for antitumor and cytotoxic activity in vitro in human bladder cancer cell lines, and compounds 3a, 3d, 3e, and 3g showed potential to treat bladder cancer.

    背景:开发从各种底物组合中合成高度官能化和复杂的1,2,3-三唑的方法在有机合成中仍然是一个重大挑战。据我们所知,尚未探索利用有机催化方法合成源自脂肪酸的1,2,3-三唑。 目标:在这方面,我们在这里描述了源自脂肪酯的一系列1,2,3-三唑的有机催化合成和抗肿瘤及细胞毒活性的初步结果。 方法:为了合成源自脂肪β-酮酸酯的1,2,3-三唑3,我们在DMSO溶剂中以70°C反应24小时,在适当的芳基叠氮化物2a-j与β-酮酸酯1a-c在5 mol% DBU存在下进行反应。通过测量可溶性MTT还原为水不溶性偶氮的减少来确定5637细胞的存活率。通过至少三次独立实验的三重复测得抑制50%细胞生长的IC50浓度,每次测试都得到结果。 结果:通过烯醇酸碱介导的有机催化,通过在1,8-二氮杂双环[5.4.0]十一烯(5 mol%)存在下,脂肪酯1与芳基叠氮化物2反应,合成了源自脂肪β-酮酸酯的1,2,3-三唑3,收率从中等到优良。所有源自棕榈酸乙酰乙酸酯1a的化合物在体外人类膀胱癌细胞系中对诱导细胞毒性进行了评估,化合物3a、3d、3e和3g显示出是治疗膀胱癌的有希望的替代方案,并且呈现出IC50的最低抑制浓度。 结论:我们描述了一种合成程序,通过DBU催化的脂肪酯与不同芳基叠氮化物的1,3-偶极环加成反应,制备了源自脂肪β-酮酸酯的1,2,3-三唑化合物。从棕榈酸乙酰乙酸酯衍生的化合物在体外人类膀胱癌细胞系中进行了抗肿瘤和细胞毒活性筛选,化合物3a、3d、3e和3g显示出治疗膀胱癌的潜力。
