Abstract

The present invention relates to the delivery of desired compounds (e.g., nucleic acids) into cells using releasable delivery systems which include complexing nucleic acids and delivery ligands.

Claims (4)

1 . A complex for delivering a nucleic acid to a mammal cell comprising: a nucleic acid non-covalently bound to a cationic first ligand such that the first ligand is covalently attached to a compound and the compound is non-covalently bound to a second ligand wherein the nucleic acid is releasable from the complex inside the mammal.

2 . The complex of claim 1 wherein the compound is a cyclodextrin.

3 . The complex of claim 1 wherein the first ligand consists of a polymer.

4 . The complex of claim 1 wherein the nucleic acid is selected from the list consisting of: DNA, RNA, double strand RNA, RNA oligonucleotides, ribozymes, antisense and polynucleotides.
