Abstract

Random sequence oligonucleotides that have antiviral activity are described, along with their use as antiviral agents. In many cases, the oligonucleotides are greater than 40 nucleotides in length. Also described are methods for the prophylaxis or treatment of a viral infection in a human or animal, and a method for the prophylaxis treatment of cancer caused by oncoviruses in a human or animal. The methods typically involve administering to a human or animal in need of such treatment, a pharmacologically acceptable, therapeutically effective amount of at least oligonucleotide that does not act by a sequence complementary mode of action.

Claims

1. A method for the treatment of a viral infection in a subject, comprising administering to a subject in need of such treatment a therapeutically effective amount of at least one pharmacologically acceptable phosphorothioated oligonucleotide formulation comprising SEQ ID NO:

22 having an antiviral activity, said viral infection being caused by a virus selected from the group consisting of HCV, HBV, Influenza A, RSV, HSV-1, HSV-2, Ebola and CMV, wherein said antiviral activity of said oligonucleotide occurs principally by a sequence independent mode of action.

2. A method for the treatment of a viral infection in a subject, comprising administering to a subject in need of such treatment a therapeutically effective amount of at least one pharmacologically acceptable phosphorothioated oligonucleotide formulation comprising SEQ ID NO:

24 having an antiviral activity, said viral infection being caused by a virus selected from the group consisting of HCV, HBV and HSV-1, wherein said antiviral activity of said oligonucleotide occurs principally by a sequence independent mode of action.
