Abstract

The peptides described herein can function as carrier peptides. These peptides can associate with (e.g., non-covalently bind) biologically active molecules or imaging agents to transport the biologically active molecules or imaging across the blood-brain barrier. In some cases, such transport may increase the effectiveness of the biological molecules or imaging agents.

Claims (234)

1. A complex, or a pharmaceutically acceptable salt thereof, comprising a biologically active molecule or an imaging agent associated with a carrier peptide, wherein the carrier peptide comprises the sequence:

(SEQ ID NO: 143)

[X]n-

L-R-X1-R-X2-X3-X4-H-L-R-X5-X6-X7-K-R-L-X8-R-D-X9

wherein:

X is lysine;

n is an integer from 4 to 20;

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; and

X9 is selected from the group consisting of A and L; and

wherein the biologically active molecule is chosen from a polypeptide; small molecule; antibody; antibody fragment; carbohydrate; polysaccharide; lipid; glycolipid; antigen; and antigenic peptide.

2. The complex of claim 1 , wherein the carrier peptide is selected from the group consisting of:
