OLIGONUCLEOTIDE COMPOUND AND METHOD FOR TREATING NIDOVIRUS INFECTIONS

摘要

A method and oligonucleotide compound for inhibiting replication of a nidovirus in virus-infected animal cells are disclosed. The compound (i) has a nuclease-resistant backbone, (ii) is capable of uptake by the infected cells, (iii) contains between 8-25 nucleotide bases, and (iv) has a sequence capable of disrupting base pairing between the transcriptional regulatory sequences in the 5′leader region of the positive-strand viral genome and negative-strand 3′subgenomic region. In practicing the method, infected cells are exposed to the compound in an amount effective to inhibit viral replication.
