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. Expand
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. Expand
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 moreExpand

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 anyExpand
Broad-spectrum antiviral activity of the carbocyclic analog of 3-deazaadenosine.
TLDR
In its activity against vesicular stomatitis virus, parainfluenza virus, measles and reo virus, C-c3 Ado proved about 100 times more potent than other established broad-spectrum antiviraL agents such as ribavirin (virazole) and (S)-DHPA ((S)-9-(2,3-dihydroxypropyl)adenine). Expand
Effect of Ribavirin on Murine Cytomegalovirus Infection

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. Expand
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. Expand
