| Zusammenfassung: | Since drug carriers are envisaged to be used in a wide variety of situations and environments, nanocarriers with diverse properties, such as biocompatibility, biodegradability, nonimmunogenicity, adequate particle size, robustness, and cell permeability, are required. Here, we report the construction of novel nanocapsules with the above-mentioned features by the self-assembly of peptides composed of oligoproline and oligoleucine (i.e., H-Pro10Leu4-NH2 and H-Pro10Leu6-NH2). The peptides self-organized via hydrogen bonds and hydrophobic interactions between oligoleucine moieties to form vesicle-like nanocapsules with cationic oligoproline exposed on the surface. The guest encapsulation experiments revealed that the nanocapsules were capable of uptake of both water-soluble and insoluble compounds. Furthermore, positively charged and/or oligoproline-based peptides are known to improve cell permeability and cellular uptake, suggesting that the peptide nanocapsules are good candidates for nanocarriers to complement liposomes and polymer micelles |
