Application Number: | 15/246,232 |
Patent Claims: | 1. A peptide comprising the sequence: TABLE-US-00006 (SEQ ID NO: 1) A.sub.p-L.sub.n-B.sub.m
wherein: (a) A is an immunoglobulin affinity ligand comprising the sequence H-W-R-G-W-Z (SEQ ID NO:26); (b) L is a linker; and (c) B is a blood-brain barrier agent comprising the sequence: TABLE-US-00007 (SEQ ID NO: 3) L-R-X1-R-X2-X3-X4-H-L-R-X5-X6-X7-K-R-L-X8-R-D-X9; wherein: X1 is selected from the group consisting of A, L, S, and V; X2 is selected from the group consisting of L and M; X3 is selected from the group consisting of A and S; X4 is selected from the group consisting of N, S, and T; X5 is selected from the group consisting of K and N; X6 is selected from the group consisting of L, M, and V; X7 is selected from the group consisting of R and P; X8 is selected from the group consisting of L and M; X9 is selected from the group consisting of A and L; n is an integer from 0 to 50; m is an integer from 1 to 3; and p is an integer from 1 to 4. 2. The peptide of claim 1, wherein the immunoglobulin affinity ligand can non-covalently binds a therapeutic immunoglobulin. 3. The peptide of claim 2, wherein the therapeutic immunoglobulin is an IgG immunoglobulin. 4. The peptide of claim 1, wherein p is 1. 5. The peptide of claim 1, wherein the linker is one or more hydrophilic amino acids. 6. The peptide of claim 5, wherein the linker is one or more lysines. 7. The peptide of claim 6, wherein n is 4. 8. The peptide of claim 1, wherein the blood-brain barrier agent is TABLE-US-00008 (SEQ ID NO: 4) L-R-V-R-L-A-S-H-L-R-K-L-R-K-R-L-L-R-D-A. 9. A complex comprising: (a) the peptide of claim 1; and (b) a therapeutic immunoglobulin. 10. The complex of claim 9, wherein the blood-brain barrier agent is TABLE-US-00009 (SEQ ID NO: 4) L-R-V-R-L-A-S-H-L-R-K-L-R-K-R-L-L-R-D-A. 11. The complex of claim 9, wherein the therapeutic immunoglobulin is selected from the group consisting of cetuximab, bococizumab, dinutuximab, racotumomab, ralpancizumab, and bevacizumab. 12. The complex of claim 9, where the peptide comprises the sequence: TABLE-US-00010 (SEQ ID NO: 42) H-W-R-G-W-Z-K-K-K-K-L-R-V-R-L-A-S-H-L-R-K-L-R-K-R- L-L-R-D-A. 13. A method of transporting a therapeutic immunoglobulin across the blood-brain barrier of a patient, the method comprising: (a) administering to the patient an effective amount of a peptide comprising the sequence: TABLE-US-00011 (SEQ ID NO: 1) A.sub.p-L.sub.n-B.sub.m wherein: i. A is an immunoglobulin affinity ligand comprising the sequence H-W-R-G-W-Z (SEQ ID NO:26); ii. L is a linker; and iii. B is a blood-brain barrier agent comprising the sequence: TABLE-US-00012 (SEQ ID NO: 3) L-R-X1-R-X2-X3-X4-H-L-R-X5-X6-X7-K-R-L-X8-R- D-X9; wherein: X1 is selected from the group consisting of A, L, S, and V; X2 is selected from the group consisting of L and M; X3 is selected from the group consisting of A and S; X4 is selected from the group consisting of N, S, and T; X5 is selected from the group consisting of K and N; X6 is selected from the group consisting of L, M, and V; X7 is selected from the group consisting of R and P; X8 is selected from the group consisting of L and M; X9 is selected from the group consisting of A and L; n is an integer from 0 to 50; m is an integer from 1 to 3; and p is an integer from 1 to 4; and (b) concurrently administering to the patient an effective amount of the therapeutic immunoglobulin. 14. The method of claim 13, wherein the immunoglobulin affinity ligand non-covalently binds the therapeutic immunoglobulin. 15. The method of claim 14, wherein the therapeutic immunoglobulin is an IgG immunoglobulin. 16. A method of treating a neurological disorder in a patient, the method comprising: (a) administering to the patient an effective amount of a peptide comprising the sequence: TABLE-US-00013 (SEQ ID NO: 1) A.sub.p-L.sub.n-B.sub.m wherein i. A is an immunoglobulin affinity ligand comprising the sequence H-W-R-G-W-Z (SEQ ID NO:26); ii. L is a linker; and iii. B is a blood-brain barrier agent comprising the sequence: TABLE-US-00014 (SEQ ID NO: 3) L-R-X1-R-X2-X3-X4-H-L-R-X5-X6-X7-K-R-L-X8-R-D-X9; wherein: X1 is selected from the group consisting of A, L, S, and V; X2 is selected from the group consisting of L and M; X3 is selected from the group consisting of A and S; X4 is selected from the group consisting of N, S, and T; X5 is selected from the group consisting of K and N; X6 is selected from the group consisting of L, M, and V; X7 is selected from the group consisting of R and P; X8 is selected from the group consisting of L and M; X9 is selected from the group consisting of A and L; n is an integer from 0 to 50; m is an integer from 1 to 3; and p is an integer from 1 to 4; and (b) concurrently administering to the patient an effective amount of a therapeutic immunoglobulin. 17.
