3′-Azidothymidine (AZT) was the first approved antiviral for the treatment of human immunodeficiency virus (HIV). Reported efforts in clicking the 3′-azido group of AZT have not yielded 1,2,3-triazoles activeagainstHIV or any other viruses. We report herein the first AZT-derived 1,2,3-triazoles with submicromolar potencies against HIV-1. The observed antiviral activities from the cytopathic effect
3'-叠氮胸苷(AZT)是第一个被批准用于治疗人类免疫缺陷病毒(HIV)的抗病毒药物。据报道,点击 AZT 的 3'-叠氮基团的努力并未产生对 HIV 或任何其他病毒具有活性的 1,2,3-三唑。我们在此报告了第一个 AZT 衍生的 1,2,3-三唑,具有亚微摩尔抗 HIV-1 效力。通过单复制周期测定证实了基于细胞病变效应(CPE)的测定中观察到的抗病毒活性。结构-活性-关系 (SAR) 研究揭示了抗病毒活性的两个关键结构特征:庞大的芳环和三唑上的 1,5-取代模式。相应三磷酸盐的生化分析显示,与 AZT 相比,ATP 介导的核苷酸切除效率较低,这与分子模型一起表明了三唑优先易位到 HIV 逆转录酶 (RT) P 位点的机制。这一机制得到了观察到的三唑类似物对 AZT 抗性 HIV 变体的耐药性倍数降低的证实(AZT 为 9 倍,而 AZT 为 56 倍)。

Cycloaddition of different acetylenic compounds on the azido function of 3′-azido-2′,3′-dideoxythymidine and 3′-azido-2′,3′-dideoxyuridine afforded products with a 1,2,3-triazol-1-yl substituent in the 3′-position. In contrast with the parent compounds, these triazolyl derivatives had no appreciable activity against human immunodeficiency virus (HIV-1).

midine (AZT) derivatives based on triazoles and triazolium salts for HIV-1 infection. The compounds were synthesized via click chemistry with Cu(I) and Ru(II) catalysts. Triazolium salts were synthesized by reaction with methyl iodide or methyl triflate in good yields. The antiviral activity of the compounds was tested using two methodologies: In method one the activity was measured on infected cells;

describe an efficient and rapid access to 3′-deoxy-3′-(4-substituted-1,2,3-triazol-1-yl)-thymidine derivatives using 1,3-dipolar cycloadditionreactioncatalyzed by copper(I). Innovative conditions allow us to generate target compounds in a one-pot reaction mixing 3′-azido-3′-deoxythymidine, alkyne, copper sulfate pentahydrate, sodium ascorbate and tris(benzyltriazolylmethyl)amine in a water:tert-butanol

relies on salvage of nucleosides for DNA synthesis and Up thymidine kinase (UpTK) provides the necessary thymidine nucleotides. The anti-HIV compound 3́-azido-3′-deoxythymidine (AZT) is a good substrate for TK. Methods for a rapid and efficient synthesis of new 3′-α-[1,2,3]triazol-3′-deoxythymidineanalogs from AZT under Huisgen conditions are described. Thirteen 3′-analogues were tested with human cytosolic
致病性支原体小脲原体( Up ) 会引起机会性感染,并依赖于核苷的挽救来进行 DNA 合成,而Up胸苷激酶 ( Up TK) 则提供必需的胸苷核苷酸。抗 HIV 化合物 3́-azido-3'-deoxythymidine (AZT) 是 TK 的良好底物。描述了在胡伊斯根条件下从 AZT 快速有效合成新的 3'-α-[1,2,3]三唑-3'-脱氧胸苷类似物的方法。使用人胞质胸苷激酶 (hTK1) 和Up TK测试了 13 种 3'-类似物。在所有情况下,Up TK 的新类似物均表现出比 hTK1 更高的效率(K m / V最大值) 。尽管如此,hTK1 仍优先被 10 个测试类似物中的 9 个抑制。构建了Up TK 和 hTK1的结构模型并用于解释动力学结果。两种酶的活性位点内的核苷有两种不同的结合模式,其中一种在细菌酶中占主导地位,另一种在 hTK1 中占主导地位。这些结果将有助于抗支原体核苷的未来开发。
