ABSTRACT:
Compounds, compositions and methods for inhibiting gene expression are disclosed. The compounds comprise oligonucleotide sequences of from about 9 to about 200 bases having a diol at either or both termini. Preferred diols are polyalkyleneglycols, preferably polyethyleneglycols. Pharmaceutical compositions comprising the compounds and a physiologically acceptable carrier and methods of inhibiting gene expression in mammals comprising administering such compounds are also provided. Methods for inhibiting nuclease cleavage of compounds are also provided.
