Abstract

Official abstract text for this publication.

Disclosed herein are surfactant peptide nanostructures wherein the peptides have repeating hydrophobic amino acids in an integer equal to or less than four. The peptide nanostructures are useful for therapeutic applications, including for delivery of drugs and siRNA.

First claim

Opening claim text (preview).

What is claimed is: 1. A drug delivery composition, said drug delivery composition comprising a peptide that consists of the amino acid sequence of AAAK (SEQ ID NO:1), wherein the peptide is present at a concentration of at least 0.01% (w/v) in an aqueous solution that has a pH from about 6 to about 8, and wherein the peptide is complexed with an siRNA. 2. The drug delivery composition of claim 1 , wherein the aqueous solution is at an ionic strength of up to 0.3 M. 3. The drug delivery composition of claim 1 , wherein the aqueous solution is isotonic. 4. The drug delivery composition of claim 1 , wherein the siRNA is for delivery to a cancer cell. 5. The drug delivery composition of claim 1 , wherein each amino acid is a D-amino acid. 6. The drug delivery composition of claim 1 , wherein the peptide is amidated at the C-terminus and acetylated at the N-terminus.
