Abstract

Adenosine, but not guanosine, was capable of blocking the inhibitory effect of 5,6-dichloro-1-beta-D-ribofuranosylbenzimidazole (DRB) on influenza virus multiplication in the chorioallantoic membrane in vitro. At virus inhibitory concentrations DRB caused marked inhibition in uptake of adenosine-8-C(14) into RNA of uninfected host cells, but it had little effect on uptake of C(14)-L-alanine into host cell proteins or on cellular oxygen consumption. The activity of DRB in inhibiting multiplication of the DNA-containing adenovirus was similar to its inhibitory activity on multiplication of the RNA-containing influenza virus. These and earlier results are discussed from the point of view of the important role of RNA in the reproduction of DNA-containing viruses.

摘要

腺苷而非鸟苷能够阻断5,6 - 二氯 - 1 - β - D - 呋喃核糖基苯并咪唑(DRB)对流感病毒在体外尿囊绒毛膜中增殖的抑制作用。在病毒抑制浓度下,DRB显著抑制未感染宿主细胞RNA对腺苷 - 8 - C¹⁴的摄取,但对C¹⁴ - L - 丙氨酸摄取到宿主细胞蛋白质中或对细胞耗氧量影响很小。DRB抑制含DNA的腺病毒增殖的活性与其对含RNA的流感病毒增殖的抑制活性相似。从RNA在含DNA病毒复制中的重要作用的角度对这些及早期结果进行了讨论。
