Abstract
The disclosure is generally directed toward the design and synthesis of peptide amphiphile (PA) molecules that comprises a peptide configured to inhibit angiogenesis. The peptide amphiphile comprises a hydrophobic tail, peptide sequence capable of beta-sheet formation; and a peptide, wherein the peptide is configured to inhibit angiogenesis. Optionally the PA further comprises a flexible linker between the peptide sequence capable of beta-sheet formation and the peptides. Further this disclosure is directed to nanostructures comprising peptide amphiphiles configured to inhibit angiogenesis.
Claims21
-22. (canceled)
A composition comprising peptide amphiphile molecules comprising:
- (a) a hydrophobic tail comprising a C6-C22 alkyl group;
- (b) a peptide comprising VA and capable of beta sheet formation;
- (c) a peptide configured to inhibit angiogenesis;
- and (d) a flexible peptide linker between the peptide comprising VA and the peptide configured to inhibit angiogenesis;
- wherein the peptide amphiphile molecules self-assemble in aqueous solution into nanofibers having comprising a hydrophobic core, stabilized by beta-sheet formation down a long axis of the nanofiber, and displaying the peptide configured to inhibit angiogenesis on the nanofiber surface.
