  2-Heteroarylimino-5-arylidene-4-thiazolidinones as a new class of non-nucleoside inhibitors of HCV NS5B polymerase

  摘要：

  Hepatitis C virus (HCV) NS5B polymerase is an important and attractive target for the development of anti-HCV drugs. Here we report on the design, synthesis and evaluation of twenty-four novel allosteric inhibitors bearing the 4-thiazolidinone scaffold as inhibitors of HCV NS5B polymerase. Eleven compounds tested were found to inhibit HCV NS5B with IC50 values ranging between 19.8 and 64.9 RM. Compound 24 was the most active of this series with an IC50 of 5.6 mu M. A number of these derivatives further exhibited strong inhibition against HCV lb and 2a genotypes in cell based antiviral assays. Molecular docking analysis predicted that the thiazolidinone derivatives bind to the NS5B thumb pocketII (TP-II). Our results suggest that further optimization of the thiazolidinone scaffold may be possible to yield new derivatives with improved enzyme- and cell-based activity. (C) 2013 Elsevier Masson SAS.

  docked into thumb II site of HCV NS5B GT4a using rigid docking approach. Eighteen compounds (7a–r) that show good docking scores were synthesized and tested in vitro against NS5B GT4a. Compounds 7b and 7n showed the best inhibitory activity (IC50 = 0.338 and 0.342 µM, respectively). Compounds 7a, 7b, 7c, 7d, 7k, 7n, 7q, and 7r that have IC50 values less than 2 µM were assessed for cellular anti-HCV GT4a

  丙型肝炎病毒（HCV）基因型4a（GT4a）在埃及盛行。尽管具有很高的抵抗力，但它并没有获得必要的科学关注。由于HCV GT4a的晶体结构NS5B（RNA依赖性RNA聚合酶）到目前为止尚未解析，因此进行了同源建模以建立和验证该酶的3D模型。检测到配体结合位点，包括变构拇指II型口袋，并将其用于前导优化。虚拟设计了六十种新的4-噻唑烷酮衍生物，并使用刚性对接方法将其对接到HCV NS5B GT4a的Thumb II位点。合成了18个具有良好对接分数的化合物（7a–r），并在体外针对NS5B GT4a进行了测试。化合物7b和7n表现出最佳的抑制活性（IC50  = 0.338和0.342 µM。使用人肝癌细胞系（Huh 7.5）对IC 50值小于2 µM的化合物7a，7b，7c，7d，7k，7n，7q和7r进行了细胞抗HCV GT4a活性评估。病毒生长抑制的百分比在79.67和94.77％之间

  A series of thiadiazole derivatives were synthesized with differently substituted benzoic acids which were cyclized to give differently substituted thiazolidin-4-one. Elemental analysis, IR, $^1H$ NMR, $^13}C$ NMR and mass spectral data confirmed the structure of the synthesized compounds. The derivatives of these moieties were evaluated for anticonvulsant activity by MES model and neurotoxicity by rotarod method. The synthesized compounds showed good potential for anticonvulsant activity besides this, the compounds also showed neurotoxic effect. It was observed that compounds with $OCH_3$ at 3, 4 position of phenyl ring [5(a-l)] showed less protection against convulsions as compared to compounds having unsubstituted phenyl ring [4(a-l)].

  一系列噻二唑衍生物通过不同取代的苯甲酸环合得到不同取代的噻唑烷-4-酮。元素分析、红外、$^1H$ NMR、$^13}C$ NMR 和质谱数据证实了合成化合物的结构。这些基团的衍生物通过MES模型评估了它们的抗惊厥活性，并通过旋转棒方法评估了神经毒性。所合成的化合物显示出良好的抗惊厥活性潜力，此外，这些化合物还表现出神经毒性效应。观察发现，相比于具有未取代苯环的化合物[4(a-l)]，在苯环3, 4位带有$OCH_3$的化合物[5(a-l)]对抗惊厥的保护作用较弱。

  A series of thiadiazole derivatives were synthesized with differently substituted benzoic acids which were cyclized to give differently substituted thiazolidin-4-one. Elemental analysis, IR, $^1H$ NMR, $^13}C$ NMR and mass spectral data confirmed the structure of the newly synthesized compounds. The derivatives of these moieties were evaluated for antimicrobial activity. Most of the synthesized compounds showed good antimicrobial activity at 200 and $100\;\mu}g/mL$. Compounds showed most significant antibacterial activity against gram negative test organism Escherichia coli and most significant antifungal activity against test organisms Aspergillus niger and Candida albicans. It was observed that compounds with $OCH_3$ at 3, 4 position of phenyl ring [5(a-l)] were more potent against microbes as compared to compounds having unsubstituted phenyl ring [4(a-l)].
