Abstract

Provided herein are oral care compositions comprising antifreeze proteins (AFPs) useful in methods of repairing or inhibiting dental erosion, promoting dental remineralization, and/or enhancing the anti-cavity effects of fluoride.

First claim

The invention claimed is:

1. A dentifrice comprising:
a. an antifreeze protein (AFP), which has been neutralized to approximately neutral or slightly basic pH;
b. an effective amount of fluoride and
c. an orally acceptable carrier,
wherein the AFP has the polypeptide sequence as set forth in SEQ ID NO: 1, SEQ ID NO: 2 or SEQ ID NO: 3, or a polypeptide sequence which arise from substitution, insertion or deletion of up to 5% of all amino acids, starting from the polypeptide sequence as set forth in SEQ ID NO: 1, SEQ ID NO: 2 or SEQ ID NO: 3, and which still has at least 50% of the biological property of the starting protein, and wherein the AFP is present in the dentifrice in an amount of from 0.01 weight % to 3 weight % by total weight of the dentifrice.

2. An oral care composition for use in repairing or inhibiting dental enamel erosion, promoting remineralization of dental enamel, and/or enhancing the anti-cavity effects of fluoride, said oral care composition comprising:
a. an AFP;
b. optionally an effective amount of fluoride; and
c. an orally acceptable carrier,
wherein the AFP has the polypeptide sequence as set forth in SEQ ID NO: 1, SEQ ID NO: 2 or SEQ ID NO: 3, or a polypeptide sequence which arise from substitution, insertion or deletion of up to 5% of all amino acids, starting from the polypeptide sequence as set forth in SEQ ID NO: 1, SEQ ID NO: 2 or SEQ ID NO: 3, and which still has at least 50% of the biological property of the starting protein, and wherein the AFP is present in the composition in an amount of from 0.01 weight % to 3 weight % by total weight of the composition.

3. The dentifrice of claim 1 wherein the AFP is coupled to a hydroxyapatite binding peptide which is selected from the group formed from SEQ ID NO:4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, and 19.

4. The dentifrice of claim 1 wherein the AFP is a homomer or heteromer of AFPs and coupled to a hydroxyapatite binding peptide which is selected from the group formed from SEQ ID NO:4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, and 19.

5. The dentifrice described in claim 1 wherein the dentifrice further comprises an effective amount of fluoride.

6. The dentifrice of claim 1 , wherein AFP has the polypeptide sequence as set forth in SEQ ID NO: 1, SEQ ID NO: 2 or SEQ ID NO: 3, or a polypeptide sequence which arise from substitution, insertion or deletion of up to 3% of all amino acids, starting from the polypeptide sequence as set forth in SEQ ID NO: 1, SEQ ID NO: 2 or SEQ ID NO: 3 and which still has at least 80% of the biological property of the starting protein, and wherein AFP is present in the composition in an amount of from 0.01 weight % to 3 weight % by total weight of the dentifrice.

7. The dentifrice of claim 1 , wherein AFP has the polypeptide sequence as set forth in SEQ ID NO: 1, SEQ ID NO: 2 or SEQ ID NO: 3, or a polypeptide sequence which arise from substitution, insertion or deletion of up to 1% of all amino acids, starting from the polypeptide sequence as set forth in SEQ ID NO: 1, SEQ ID NO: 2 or SEQ ID NO: 3 and which still has at least 90% of the biological property of the starting protein, and wherein AFP is present in the composition in an amount of from 0.01 weight % to 3 weight % by total weight of the dentifrice.

8. The dentifrice of claim 1 , wherein the AFP has the polypeptide sequence of SEQ ID NO: 1.

9. The dentifrice of claim 1 , wherein the AFP has the polypeptide sequence of SEQ ID NO: 2.

10. The dentifrice of claim 1 , wherein the AFP has the polypeptide sequence of SEQ ID NO: 3.

11. The oral care composition of claim 2 wherein the AFP is coupled to a hydroxyapatite binding peptide which is selected from the group formed from SEQ ID NO:4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, and 19.

12. The oral care composition of claim 2 wherein the AFP is a homomer or heteromer of AFPs and coupled to a hydroxyapatite binding peptide which is selected from the group formed from SEQ ID NO:4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, and 19.

13. The oral care composition described in claim 2 wherein the oral care composition further comprises an effective amount of fluoride.

14. The oral care composition of claim 2 , wherein AFP has the polypeptide sequence as set forth in SEQ ID NO: 1, SEQ ID NO: 2 or SEQ ID NO: 3, or a polypeptide sequence which arise from substitution, insertion or deletion of up to 3% of all amino acids, starting from the polypeptide sequence as set forth in SEQ ID NO: 1, SEQ ID NO: 2 or SEQ ID NO: 3 and which still has at least 80% of the biological property of the starting protein, and wherein AFP is present in the composition in an amount of from 0.01 weight % to 3 weight % by total weight of the composition.

15. The oral care composition of claim 2 , wherein AFP has the polypeptide sequence as set forth in SEQ ID NO: 1, SEQ ID NO: 2 or SEQ ID NO: 3, or a polypeptide sequence which arise from substitution, insertion or deletion of up to 1% of all amino acids, starting from the polypeptide sequence as set forth in SEQ ID NO: 1, SEQ ID NO: 2 or SEQ ID NO: 3 and which still has at least 90% of the biological property of the starting protein, and wherein AFP is present in the composition in an amount of from 0.01 weight % to 3 weight % by total weight of the composition.

16. The oral care composition of claim 2 , wherein the AFP has the polypeptide sequence of SEQ ID NO: 1.

17. The oral care composition of claim 2 , wherein the AFP has the polypeptide sequence of SEQ ID NO: 2.

18. The oral care composition of claim 2 , wherein the AFP has the polypeptide sequence of SEQ ID NO: 3.
