Ribavirin 5'-triphosphate (RTP), derived from the broad-spectrum antiviral compound ribavirin (Virazole), can selectively inhibit influenza virus ribonucleic acid polymerase in a cell-free assay. Ribavirin and its 5'-monophosphate have no effect on the polymerase. The inhibition is competitive with respect to adenosine 5'-triphosphate and guanosine 5'-triphosphate. RTP also inhibits ApG- and GpC-stimulated influenza virus ribonucleic acid polymerase. Since ribavirin is phosphorylated in the cell, the inhibition of influenza multiplication in the cell may also be caused by RTP.
利巴韦林5'-三磷酸(RTP)由广谱抗病毒化合物利巴韦林(病毒唑)衍生而来,在无细胞试验中可选择性抑制流感病毒核糖核酸聚合酶。利巴韦林及其5'-单磷酸对该聚合酶无作用。这种抑制作用在三磷酸腺苷和三磷酸鸟苷方面具有竞争性。RTP还抑制ApG和GpC刺激的流感病毒核糖核酸聚合酶。由于利巴韦林在细胞内被磷酸化,细胞内流感增殖的抑制也可能由RTP引起。
