The therapeutic effectiveness of six antiviral agents and certain combinations were evaluated under the same experimental conditions during systemic HVH infection of mice. The agents used were adenine arabinoside (ARA-A), cytosine arabinoside (ARA-C), idoxuridine (IDU), polyinosinic polycytidylic acid (In Cn), interferon, and phosphonoacetic acid (PAA). Treatment with ARA-A begun as late as 3 days after the virus infection was highly effective in preventing death. Interferon begun on Day 4 prolonged survival. In similar experiments, no antiviral effect of either IDU or PAA could be demonstrated, while therapy with ARA-C potentiated the infection. Of the drug combinations tested, none was more effective than the better agent alone. Unexpectedly a protective and nontoxic dose of ARA-A when combined with a nontoxic dose of In Cn resulted in a synergistic mortality in uninfected mice.
