                                摘要:
                                A series of 4H-pyrazolo[1,5-a]pyrimidin-7-one derivatives was synthesized and evaluated for inhibitory activity against HCV NS5B RNA-dependent RNA polymerase. A number of these compounds exhibited potent activity in enzymatic assay. The synthesis and structure-activity relationship are also described. (C) 2009 Elsevier Ltd.
