title: Mechanism of interferon action III--significance of pppA2'p5'A2'p5'A in the antiviral action of interferon.
abstract: This paper is to evidence that the antiviral effect of pppA2'P5'A2'P5'A(2'-5'P3A3) could cover a wide spectrum of viruses, the RNA viruses such as influenza H3N2/77, influenza H1N1/77, ECHO11, rhino, Sendai, Sindbis and VSV, and the DNA viruses such as herpes (type I). In addition, the antiviral effect of 2'-5'P3A3 on ECHO11 virus, as compared with other viruses, is more efficient than that of IFN. It seems likely that 2'-5'P3A3 plays an important role in the antiviral action of IFN. After comparing the action of 2'-5'P3A3 with interferon (IFN), it has appeared that the action of 2'-5'P3A3 is something parallel to that of IFN for most viruses. For a few viruses, however, considerable differences have been observed.
