Abstract
Aim: Endosome escape is essential for developing effective nonviral gene delivery systems. Herein, three endosome-disrupting peptides (HA2(1–20), GALA and KALA) were incorporated into a multicomponent oligonucleotide delivery system to identify which peptide imparted the most favorable endosome escape and toxicity profile. Materials & methods: Copper (I)-catalyzed azide-alkyne cycloaddition was used to construct multicomponent delivery vectors. The systems were evaluated for size, toxicity, cellular uptake and endosome escape activity. Results: Each system condensed plasmid DNA to form nanosized particles. The highest cellular uptake and endosome escape were associated with GALA and KALA containing systems, with KALA incorporation correlating with greater toxicity. Conclusion: GALA was selected as the most promising endosome-disrupting peptide for incorporation into the nanosized oligonucleotide delivery system.

Abstract
A novel random copolypeptide of ornithine, arginine, glycine, and aspartic acid [Poly(ornithine-co-arginine-co-glycine-co-aspartic acid), Poly(O,R,G,D)] has been prepared through ring-opening polymerization of N-δ-carbobenzoxy-l-ornithine N-carboxyanhydride [Orn(Cbz)-NCA)], l-glycine N-carboxyanhydride (Gly-NCA) and β-benzyl l-aspartate N-carboxyanhydride [Asp(Bn)-NCA], following by subsequent deprotection and guanidization. The structure of Poly(O,R,G,D) was confirmed by nuclear magnetic resonance (NMR) spectroscopy and gel permeation chromatography (GPC). Low cytotoxicity of Poly(O,R,G,D) was confirmed from MTT assay. The Poly(O,R,G,D) contain some internal sequences of RXXR (X = O, R, G, or D) that could be proteolytically cleaved to expose the cryptic CendR element and bind to Neuropilin-1. This would lead to vascular and tissue permeabilization. Therefore trypsin-cleaved Poly(O,R,G,D) increase the vascular leakage of Evans blue from dermal microvessels at the injection site in vivo skin permeability assay. The intratumoral injection of the Poly(O,R,G,D) significantly enhanced the concentration of cisplatin-loaded nanoparticles in MCF-7 solid tumors. These results show that Poly(O,R,G,D) could increase the vascular leakage and tissue penetration of nanoparticles in a solid tumor and can be used as a potential polymeric tumor-penetrating agent.

Abstract
Atomistic simulations of model nonpolar nanotubes in a Stockmayer liquid are carried out for varying nanotube diameter and nanotube-solvent interactions to investigate solvophobic interactions in generic dipolar solvents. We have considered model armchair type single-walled nonpolar nanotubes with increasing radii from (5,5) to (12,12). The interactions between solute and solvent molecules are modeled by the well-known Lennard-Jones and repulsive Weeks-Chandler-Andersen potentials. We have investigated the density profiles and microscopic arrangement of Stockmayer molecules, orientational profiles of their dipole vectors, time dependence of their occupation, and also the translational and rotational motion of solvent molecules in confined environments of the cylindrical nanopores and also in their external peripheral regions. The present results of structural and dynamical properties of Stockmayer molecules inside and near atomistically rough nonpolar surfaces including their wetting and dewetting behavior for varying interactions provide a more generic picture of solvophobic effects experienced by simple dipolar liquids without any specific interactions such as hydrogen bonds.

Abstract
Block polypeptides are an emerging class of materials that have the potential to be used in many biomedical applications, including the field of drug delivery. We have previously developed a negatively charged block copolypeptide, poly(L-glutamate)60-b-poly(L-leucine)20 (E60L20), which forms spherical vesicles in aqueous solution. Since these vesicles are negatively charged, they are minimally toxic toward cells. However, the negative charge also inhibits these vesicles from effectively being internalized by cells, which can be problematic as many therapeutics have intracellular targets. To overcome this limitation of the E60L20 vesicles, transferrin (Tf) was conjugated onto the vesicle surface, since the receptor for Tf is overexpressed on cancer cells. The enhanced uptake of the Tf-conjugated vesicle was verified through confocal microscopy. Furthermore, endocytosis and immunostaining experiments confirmed that the Tf conjugated on the vesicle surface plays a critical role in the internalization and subsequent intracellular trafficking behavior of the vesicles.

Abstract
An arginine-leucine block copolypeptide (R60 L20 ) is synthesized, which is capable of forming vesicles with controllable sizes, able to transport hydrophilic cargo across the cell membrane, and exhibit relatively low cytotoxicity. The R60 L20 vesicles also possess the ability to deliver DNA into mammalian cells for transfection. Although the transfection efficiency is lower than that of the commercially available transfection agent Lipofectamine 2000, the R60 L20 vesicles are able to achieve transfection with significantly lower cytotoxicity and immunogenicity. This behavior is potentially due to its stronger interaction with DNA which subsequently provides better protection against anionic heparin.
