Details for Patent: 7,196,069

Title:High affinity RNA ligands of basic fibroblast growth factor
Abstract: Methods are described for the identification and preparation of nucleic acid ligand solutions to basic fibroblast growth factor (bFGF). Included in the invention are nucleic acid ligands to bFGF which are inhibitors of bFGF and 2'-amino-modified RNA ligands to bFGF.
Inventor(s): Janjic; Nebojsa (Boulder, CO), Gold; Larry (Boulder, CO)
Assignee: Gilead Sciences, Inc. (Forster City, CA)
Filing Date:Jul 06, 2004
Application Number:10/885,403
Claims:1. A pharmaceutical composition comprising a non-naturally occurring nucleic acid ligand to basic fibroblast growth factor (bFGF), wherein said nucleic acid ligand inhibits the binding of bFGF to its receptor on the surface of a cell.

2. The composition of claim 1 wherein said nucleic acid ligand is single-stranded.

3. The composition of claim 2 wherein said nucleic acid ligand is an RNA ligand.

4. The composition of claim 3 wherein said nucleic acid ligand is comprised of 2'NH.sub.2(2'-amino)modified nucleotides.

5. A method of inhibiting the binding of basic fibroblast growth factor (bFGF) to its receptor on the surface of a cell in vivo comprising administering to said cell the pharmaceutical composition of claim 1.

6. The method of claim 5 wherein said nucleic acid ligand is single-stranded.

7. The method of claim 6 wherein said nucleic acid ligand is an RNA ligand.

8. The method of claim 7 wherein said nucleic acid ligand is comprised of 2'NH.sub.2(2'-amino)modified nucleotides.

9. The method of claim 8 wherein said nucleic acid ligand comprises SEQ ID NO:104.
