Abstract

The present invention relates to a conjugate of cell penetrating peptide and an active ingredient; and its use. Specifically, a conjugate including a cell penetrating peptide which is a peptide comprising any one amino acid sequence of SEQ ID NO: 2 to SEQ ID NO: 178, a fragment of any one sequence of SEQ ID NO: 2 to SEQ ID NO: 178, or a peptide having above 80% homology with the above-mentioned sequence; and a composition comprising the same are disclosed.

Claims (18)

1. A conjugate comprising a cell penetrating carrier peptide and an active ingredient,

wherein the carrier peptide is 12 amino acids in length and consists of the amino acid sequence of SEQ ID NO: 105.

2. The conjugate according to claim 1 , wherein the active ingredient is a protein, nucleic acid, peptide, lipid, mineral, sugar, nano-particle, contrast agent, or drug.

3. The conjugate according to claim 1 , wherein the carrier peptide is bonded to the active ingredient via a covalent bond and optionally mediated by a linker.

4. The conjugate according to claim 1 , wherein the carrier peptide is bonded to the active ingredient via a non-covalent bond.

5. The conjugate according to claim 2 , wherein the active ingredient is a protein or a peptide.

6. The conjugate according to claim 5 , wherein the active ingredient is a cytokine, antibody, fragment of antibody, therapeutic enzyme, soluble receptor or ligand.

8. The conjugate according, to claim 2 , wherein the contrast agent comprises iron.

9. The conjugate according to claim 8 , wherein the contrast agent is a ferrocene carboxylate.

10. A contrast agent comprising the conjugate of claim 1 .

11. A cell comprising the contrast agent according to claim 10 .

12. The cell according to claim 11 , wherein the cell is a stem cell.

13. A composition comprising the conjugate according to claim 1 as an active ingredient; wherein the composition is selected from a pharmaceutical composition, a cosmetic composition, and a health food composition.

14. The composition according to claim 13 , wherein the composition is a pharmaceutical composition.

15. The composition according to claim 13 , wherein the composition is a cosmetic composition.

16. The composition according to claim 13 , wherein the composition is a health food composition.
