Treatment of diseases and conditions mediated by increased phosphorylation
View Patent ↗The invention provides methods for the treatment of diseases and conditions mediated by increased phosphorylation, such as inflammation and cancer. The invention also provides methods for the inhibition of increased phosphorylation in cells, tissues and organs. The methods utilize a phosphate acceptor compound (PAC). The invention also provides products comprising a PAC.
1. A pharmaceutical composition consisting essentially of a phosvitin or a phosvitin fragment of at least 20 consecutive amino acids including at least one phosphorylatable amino acid which is at least 70% dephosphorylated and a pharmaceutically-acceptable carrier, wherein the pharmaceutical composition is not an aqueous solution or a lyophilized material.
2. The composition of claim 1 wherein the phosvitin is chicken phosvitin.
3. The composition of claim 2 wherein the phosvitin or fragment thereof is at least about 90% dephosphorylated.
4. The composition of claim 3 wherein the phosvitin or fragment thereof is unphosphorylated.
5. The composition of claim 1 wherein the phosvitin or fragment thereof is at least about 90% dephosphorylated.
6. The composition of claim 5 wherein the phosvitin or fragment thereof is unphosphorylated.
7. A pharmaceutical composition which is formulated for topical administration to an animal and which is not an aqueous solution, the composition consisting essentially of a phosvitin or a phosvitin fragment of at least 20 consecutive amino acids including at least one phosphorylatable amino acid which is at least 70% dephosphorylated and a pharmaceutically-acceptable carrier.
8. The composition of claim 7 wherein the phosvitin is chicken phosvitin.
9. The composition of claim 8 wherein the phosvitin or fragment thereof is at least about 90% dephosphorylated.
10. The composition of claim 9 wherein the phosvitin or fragment thereof is unphosphorylated.
11. The pharmaceutical composition of any one of claim 8 or 9 - 10 which is formulated for topical administration to the skin of an animal.
12. The pharmaceutical composition of any one of claim 8 or 9 - 10 which is drops, a spray, an aerosol or an inhalant.
13. The pharmaceutical composition of any one of claim 8 or 9 - 10 which is a powder or a foam.
14. The pharmaceutical composition of any one of claim 8 or 9 - 10 which is a lotion, a gel, a cream, an ointment or a paste.
15. The pharmaceutical composition of claim 14 which is an ointment or a cream.
16. The composition of claim 7 wherein the phosvitin or fragment thereof is at least about 90% dephosphorylated.
17. The composition of claim 16 wherein the phosvitin or fragment thereof is unphosphorylated.
18. The pharmaceutical composition of any one of claim 7 , 16 or 17 which is formulated for topical administration to the skin of an animal.
19. The pharmaceutical composition of any one of claim 1 , 7 , 16 or 17 which is drops, a spray, an aerosol or an inhalant.
20. The pharmaceutical composition of any one of claim 1 , 7 , 16 or 17 which is a powder or a foam.
21. The pharmaceutical composition of any one of claim 1 , 7 , 16 or 17 which is a lotion, a gel, a cream, an ointment or a paste.
22. The pharmaceutical composition of claim 21 which is an ointment or a cream.
23. A kit for contacting a cell, a tissue or an organ that has been removed from an animal, the kit comprising:
(a) a container holding a phosvitin or fragment of at least 20 consecutive amino acids including at least one phosphorylatable amino acid which is at least 70% dephosphorylated; and
(b) instructions describing how to use the kit to contact a cell, tissue or organ with the phosvitin or fragment thereof in the kit.
24. A pharmaceutical composition comprising a phosvitin or a phosvitin fragment of at least 20 consecutive amino acids including at least one phosphorylatable amino acid which is at least 70% dephosphorylated and has a targeting molecule covalently attached to it and a pharmaceutically-acceptable carrier.
25. The composition of claim 24 wherein the composition is formulated for topical administration to an animal.
