Cyclodextrin cellular delivery system for oligonucleotides

摘要

Disclosed is a composition including an oligonucleotide complexed with a cyclodextrin. The oligonucleotide may be noncovalently associated with the cyclodextrin. Alternatively, the oligonucleotide may be covalently complexed with adamantane which is noncovalently associated with the cyclodextrin. Also disclosed are methods of enhancing the cellular uptake and intracellular concentration of oligonucleotides, methods of increasing the solubility of an oligonucleotide in a cell, and methods of treating a cell for viral infection or to prevent viral infection.
