  Synthesis and antiviral activity of some new 1H-1,2,4-triazole derivatives

  摘要：

  A series of new 1H-1,2,4-triazole derivatives was synthesised and evaluated in vitro for activity against various DNA and RNA viruses. Compounds 1-benzyl-5-(4-methylphenyl)-3-(2-pyrazinyl)-1H-1,2,4-triazole 2b, 1-benzyl-5-(3-methylphenyl)-3-(2-pyrazinyl)-1H-1,2,4-triazole 2c and 1-[(2-hydroxyethoxy)methyl]-5-(3-methylphenyl)-3-(2-pyrazinyl)-1H-1,2,4-triazole 4h proved active against reovirus-1, and compounds 1-[(2-hydroxyethoxy)methyl]-5-phenyl-3-(2-pyrazinyl)-1H-1,2,4-triazole 4f and 1-[(2-hydroxyethoxy)methyl]-5-(3-methylphenyl-3-(2-pyrazinyl)-1H-1,2,4-triazole 4h against parainfluenza-3 virus, in Vero cells at concentrations that were 5- to 40-fold lower than the cytotoxic concentrations required to alter normal cell morphology.
