AB A 15-mer C-5 propyne modified phosphorothioate oligodeoxynucleotide
antisense to rev was approximately 5-fold more effective in providing
viral inhibition compared to a 28-mer unmodified phosphorothioate
oligodeoxynucleotide targeted to the same sequence and previously shown
to inhibit HIV-1 in a sequence-dependent manner. The antiviral effect
was obtained by lipofection or simple addition of 0.2-1 microM modified
oligodeoxynucleotide to the culture medium of H9 cells chronically
infected with the HIV-1LAI isolate of human immunodeficiency virus type
1. We conclude that C-5 propyne oligodeoxynucleotides in accordance with
previous findings by others are superior to unmodified phosphorothioates
in providing inhibition of HIV-1 in a sequence-dependent manner and that
this inhibition can be conferred by oligodeoxynucleotides in free
solution.
