  Synthesis of Natural Flutimide and Analogous Fully Substituted Pyrazine-2,6-diones, Endonuclease Inhibitors of Influenza Virus

  摘要：

  Flutimide, a fully substituted 1-hydroxy-3H-pyrazine-2,6-dione, is a fungal metabolite isolated from a new species of Delitschia. cofertaspora. It has been shown to selectively inhibit cap-dependent endonuclease activity of influenza virus A. The inhibition of this activity is a target for the potential development of a therapeutic agent to treat influenza infections. A convergent total synthesis of flutimide starting from L-leucine has been described. The synthetic methodology has been extended to include the synthesis of specifically designed aromatic analogues of flutimide, some of which exhibited greater than 7-fold improvement in activity, The most potent compounds were those with p-fluorobenzylidene or p-methoxybenzylidene substitutions at C-5 of 3H-pyrazine-2,6-dione and showed IC50 values of 0.9 and 0.8 muM, respectively. The details of the rationale for the synthetic design, syntheses, and biological activities of these analogues are described.
