3'-5' L-capped-antisense oligodeoxynucleotides targeted at the SV40 T-antigen gene: pharmacological and biological properties.
This paper reports on some pharmacological and biological properties of 22-mer antisense oligodeoxynucleotides which contain an L-deoxyribonucleoside at each terminus. Compared with natural compounds, of which they retain the DNA hybridizing ability and the cell uptake mechanism, the L-22-mers exhibited an increased resistance to phosphodiesterase degradation, an apparent higher intracellular concentration and a longer intracellular half life. Antiviral activity was not prominent.
