Antisense antiviral agent and method for treating ssRNA viral infection
First Claim
Patent Images
1. A method of inhibiting infection by an HCV virus in a subject, comprising administering to the subject, a therapeutically effective amount of a morpholino oligonucleotide composed of 12 to 30 morpholino subunits that is substantially complementary to the target sequence set forth in SEQ ID NO:
- 37, wherein the oligonucleotide has a Tm, with respect to binding to the target sequence of greater than about 50°
C., and wherein the morpholino subunits are linked by uncharged phosphorodiamidate linkages interspersed with at least two and up to eight phosphorodiamidate linkages containing piperazine groups.

Abstract
The invention provides antisense antiviral compounds and methods of their use in inhibition of growth of viruses of the picornavirus, calicivirus, togavirus and flavivirus families, as in treatment of a viral infection. The antisense antiviral compounds have morpholino subunits linked by uncharged phosphorodiamidate linkages interspersed with cationic phosphorodiamidate linkages.
