  Synthesis and Anti-HSV-1 Activity of 6 Substituted Pyrazolo[3,4-d]Pyridazin-7-one Nucleosides

  摘要：

  a new series of 6-substituted N-1- and N-2 -beta-D-ribofuranosyl-pyrazolo[3,4-d]pyridazin-7(6H)-one derivatives (8a-g, 9b-d and 9f-g) has been prepared in the aim to explore the structure-activity relationships and improve the antiviral activity of a series of N-1-and N-2-beta-D-ribofuranosyl-pyrazolo[4,3-d] pyrimidin-7(6H)-one derivatives previously reported by us. The studied compounds were preliminary tested for their in vitro antiviral activity against HSV-1. Among them 8f and 9f were found 2 fold more active than those belonging to the parent series.
