A novel class of potent influenza virus inhibitors: Polysubstituted acylthiourea and its fused heterocycle derivatives
摘要:
A series of polysubstituted and fused heterocycle derivatives of acylthiourea was prepared and the biological activity against influenza virus was evaluated. Of the analogues that demonstrated IC(50)s < 0.1 mu M, acylthiourea derivatives 16 and 50 were further investigated as candidates with the most potential for future development. The SAR of these compounds are discussed and they represent a novel class of highly potent and selective inhibitors of influenza virus. (c) 2005 Published by Elsevier Ltd.

A series of substituted-nicotinyl thioureaderivativescontainingpyrimidinering were synthesized in good to excellent yield using PEG-400 as solid–liquid phasetransfer catalyst underultrasonicirradiation. The structures of all newly synthesized compounds were elucidated and confirmed by IR, 1H NMR and elemental analysis. The preliminary biological tests show that some of the target compounds present
在超声辐射下,使用PEG-400作为固液相转移催化剂,合成了一系列含有嘧啶环的取代烟酰胺基硫脲衍生物,收率良好。通过IR,1 H NMR和元素分析阐明并确认了所有新合成的化合物的结构。初步的生物学测试表明,某些目标化合物对双子叶植物的根和茎具有良好的抑制活性,对单子叶植物是安全的。
