  Discovery and structure–activity relationships study of novel thieno[2,3-b]pyridine analogues as hepatitis C virus inhibitors

  摘要：

  Current treatment for hepatitis C is barely satisfactory, there is an urgent need to develop novel agents for combating hepatitis C virus infection. This study discovered a new class of thieno[ 2,3-b] pyridine derivatives as HCV inhibitors. First, a hit compound characterized by a thienopyridine core was identified in a cell-based screening of our privileged small molecule library. And then, structure activity relationship study of the hit compound led to the discovery of several potent compounds without obvious cytotoxicity in vitro (12c, EC50 = 3.3 mu M, SI > 30.3, 12b, EC50 = 3.5 mu M, SI > 28.6, 10l, EC50 = 3.9 mu M, SI > 25.6, 12o, EC50 = 4.5 mu M, SI > 22.2, respectively). Although the mechanism of them had not been clearly elucidated, our preliminary optimization of this class of compounds had provided us a start point to develop new anti-HCV agents.

  摘要：

  吡啶甲酸和吡啶甲酸盐化合物是一类卓越的合成植物生长素除草剂。近年来，两种新的吡啶甲酸酯类化合物甲基卤昔芬（ArylexTM 活性）和氟吡唑醚苄基（RinskorTM 活性）已作为新型除草剂上市。以其结构骨架为模板，设计合成了33个4-amino-3,5-dicholor-6-(5-aryl-substituted-1-pytazolyl)-2-picolinic acid化合物，用于发现具有强效除草作用的化合物活动。测试化合物对拟南芥根部生长的抑制活性，结果表明化合物V-7的IC50值比商业除草剂halauxifen-methyl低45倍。分子对接分析表明，化合物 V-7 与受体生长素信号转导 F-box 蛋白 5 (AFB5) 的对接比毒草胺更密集。根据这些 IC50 值构建自适应三维定量构效关系模型，以指导下一步的合成策略。新化合物的除草试验表明，化合物V-8在300 gha-1剂量下

• Synthesis, Fungicidal Activity and Mode of Action of 4-Phenyl-6-trifluoromethyl-2-aminopyrimidines against Botrytis cinerea

  日期：——

  Anilinopyrimidines are the main chemical agents for management of Botrytis cinerea. However, the drug resistance in fungi against this kind of compounds is very serious. To explore new potential fungicides against B. cinerea, a series of 4-phenyl-6-trifluoromethyl-2-amino-pyrimidine compounds (compounds III-1 to III-22) were synthesized, and their structures were confirmed by 1H-NMR, IR and MS. Most of these compounds possessed excellent fungicidal activity. The compounds III-3 and III-13 showed higher fungicidal activity than the positive control pyrimethanil on fructose gelatin agar (FGA), and compound III-3 on potato dextrose agar (PDA) indicated high activity compared to the positive control cyprodinil. In vivo greenhouse results indicated that the activity of compounds III-3, III-8, and III-11 was significantly higher than that of the fungicide pyrimethanil. Scanning electron micrography (SEM) and transmission electron micrography (TEM) were applied to illustrate the mechanism of title compounds against B. cinerea. The title compounds, especially those containing a fluorine atom at the ortho-position on the benzene ring, could maintain the antifungal activity against B. cinerea, but their mechanism of action is different from that of cyprodinil. The present study lays a good foundation for us to find more efficient reagents against B. cinerea.

  苯胺嘧啶类是防治灰葡萄孢的主要化学药剂。然而，真菌对此类化合物的耐药性非常严重。为了探索新的防治灰葡萄孢的潜在杀菌剂，合成了一系列4-苯基-6-三氟甲基-2-氨基嘧啶类化合物(III-1至III-22)，并通过1H-NMR、IR和MS确认了其结构。这些化合物大多具有优异的杀菌活性。化合物III-3和III-13在果糖明胶琼脂(FGA)上的杀菌活性高于阳性对照嘧菌胺，化合物III-3在马铃薯葡萄糖琼脂(PDA)上的活性表明其与阳性对照环丙酰菌胺相比具有高活性。温室试验结果表明，化合物III-3、III-8和III-11的活性显著高于杀菌剂嘧菌胺。通过扫描电子显微镜(SEM)和透射电子显微镜(TEM)说明了这些化合物对灰葡萄孢的作用机制。这些化合物，特别是含有苯环上邻位氟原子的化合物，能够维持对灰葡萄孢的抗真菌活性，但其作用机制与环丙酰菌胺不同。本研究为我们寻找更高效的防治灰葡萄孢的药剂奠定了良好的基础。
