Virazole is a synthetic nucleoside active in tissue culture against at least 16 DNA and RNA viruses. Applied topically, it inhibits herpetic keratitis in rabbits and tail lesions induced by herpes, vaccinia, and vesicular stomatitis viruses in mice. Injected intraperitoneally into mice, it inhibits splenomegaly and hepatomegaly induced by Friend leukemia virus and respiratory infections caused by influenza AO, A2, and B viruses and parainfluenza 1 virus. infections is also effective. 

EFFICACY OF RIBAVIRIN AGAINST INFLUENZA VIRUS IN TISSUE CULTURE AND IN MICE

TLDR
Efficacy against influenza virus type A, A2, and B infections in mice has been confirmed by us, and the results of experiments that bear on the effects of the drug on the infectious process are presented.

Molecular mechanisms of action of ribavirin.

TLDR
The major mechanisms of action of ribavirin are described, reported to slow the development of AIDS in HIV-infected patients and to be able to treat infections due to HIV.

Inhibition of Respiratory Syncytial Virus Replication in vitro by a Pyrazole Dicarboxamide Analogue of Ribavirin

1-β-D-Ribofuranosylpyrazole-3,4-dicarboxamide (GR-92938X) was found to be an inhibitor of respiratory syncytial virus in vitro, with a potency equivalent to that of ribavirin. The compound was more

1-β-d-Ribofuranosyl-1,2,4-triazole-3-carboxamide (Virazole) was found to possess significant antiviral activity against aerosol-induced or intranasally induced influenza A0, A2, and B virus

An evaluation of a new antiviral agent "virazole" against influenza virus infections.

A new antiviral agent Virazole (1-B-D-Ribofuranosyl-1, 2, 4-triazole-3-carboxamide) was tested for its antiviral effect against influenza A virus infections both in vitro and in vivo. Withoutt any

Effect of Ribavirin on Murine Cytomegalovirus Infection

Ribavirin (1-β-d-ribofuranosyl-1,2,4-triazole-3-carboxamide), a new synthetic nucleoside, inhibited murine cytomegalovirus in cell culture. This was shown by the inhibition of viral cytopathic effect

SEARCHING FOR ANTIVIRAL MATERIALS FROM MICROBIAL FERMENTATIONS

TLDR
This report is an account of a joint endeavor at Parke-Davis and Southern Research Institute (Birmingham, Ala.) to obtain antiviral materials from microbial fermentations, beginning with culture isolation and ending with preparation of chemical concentrates.

Use of disposable micro tissue culture plates for antiviral and interferon induction studies.

TLDR
A reproducible test system requiring small amounts of test compound was developed for evaluating antiviral and interferon-inducing activity and known active compounds evaluated in this microplate system had activity similar to that seen in macro in vitro systems.

TLDR
A safe and relatively inexpensive laboratory apparatus for the experimental airborne infection of as many as 100 mice at a time and has been used for the production of murine pulmonary tuberculosis with tubercle bacilli cultivated in Tween-albumin liquid medium.
