Two series (degree of polymerization: 20-200) of polylysines with Z and TFA protecting groups were synthesized, and their behavior in a range of analytical methods was investigated. Gel permeation chromatography of the smaller polypeptides reveals a bimodal distribution, which is lost in larger polymers. With the help of GPC, NMR, circular dichroism (CD), and MALDI-TOF, it was demonstrated that the bimodal distribution is not due to terminated chains or other side reactions. Our results indicate that the bimodality is caused by a change in secondary structure of the growing peptide chain that occurs around a degree of polymerization of about 15. This change in secondary structure interferes strongly with the most used analysis method for polymers – GPC – by producing a bimodal distribution as an artifact. After deprotection, the polypeptides were found to exhibit exclusively random coil conformation, and thus a monomodal GPC elugram was obtained. The effect can be explained by a 1.6-fold increase in the hydrodynamic volume at the coil-helix transition. This work demostrates that secondary structures need to be carefully considered when performing standard analysis on polypeptidic systems.

A dual stimulus-responsive mPEG-SS-PLL15-glutaraldehyde star (mPEG-SS-PLL15-star) catiomer is developed and biologically evaluated. The catiomer system combines redox-sensitive removal of an external PEG shell with acid-induced escape from the endosomal compartment. The design rationale for PEG shell removal is to augment intracellular uptake of mPEG-SS-PLL 15-star/DNA complexes in the presence of tumor-relevant glutathione (GSH) concentration, while the acid-induced dissociation is to accelerate the release of genetic payload following successful internalization into targeted cells. Size alterations of complexes in the presence of 10 mM GSH suggest stimulus-induced shedding of external PEG layers under redox conditions that intracellularly present in the tumor microenvironment. Dynamic laser light scattering experiments under endosomal pH conditions show rapid destabilization of mPEG-SS-PLL15-star/DNA complexes that is followed by facilitating efficient release of encapsulated DNA, as demonstrated by agarose gel electrophoresis. Biological efficacy assessment using pEGFP-C1 plasmid DNA encoding green fluorescence protein and pGL-3 plasmid DNA encoding luciferase as reporter genes indicate comparable transfection efficiency of 293T cells of the catiomer with a conventional polyethyleneimine (bPEI-25k)-based gene delivery system. These experimental results show that mPEG-SS-PLL15-star represents a promising design for future nonviral gene delivery applications with high DNA binding ability, low cytotoxicity, and high transfection efficiency.

Reduction-sensitive, amphiphilic dextran derivatives were developed from disulfide-linked dextran-g-poly-(N-epsilon-carbobenzyloxy-l-lysine) graft polymer (Dex-g-SS-PZLL), and used as theranostic nanocarriers for chemotherapy and MR imaging. Dex-g-SS-PZLLs were synthesized by click conjugation between azidized dextran (Dex-N3, 40 kD) and alpha-alkyne-SS-PZLL (degree of polymerization = 10, 15 and 25). The chemical structures of dextran derivatives were characterized by Fourier transform infrared spectroscopy and nuclear magnetic resonance analyses. Owing to their amphiphilic nature, these copolymers can self-assemble into spherical nanosized micelles in an aqueous medium, as confirmed by fluorometry, transmission electron microscopy and dynamic light scattering. Interestingly, the hydrodynamic radii of the micelles (65-100 nm in diameter) were dependent on the block length of PZLL, and their critical micelle concentrations were in the range of 0.020-0.007 mg mL-1, which decreased as the length of PZLL increased. The anticancer drug doxorubicin (DOX) and superparamagnetic iron oxide (SPIO) nanoparticles (NPs), as the magnetic resonance imaging (MRI) contrast agent, were simultaneously encapsulated in the hydrophobic core of the micelles by the dialysis method. The release profiles of encapsulated DOX from SPIO/DOX-loaded micelles were shown to be rapid in the presence of 10 mM glutathione (GSH) within 24 h, whereas less than 30% DOX was released from reduction insensitive Dex-g-PZLL micelles in 48 h. Only about 35% DOX was released from Dex-g-SS-PZLL micelles in the same timeframe. According to the in vitro cytotoxicity test, it was found that reduction-sensitive micelles showed higher toxicity to HepG2 cancer cells than the reduction-insensitive micelles incubated with equivalent DOX concentration. Flow cytometry and fluorescence microscopy analyses further demonstrated that the reduction-sensitive micelles exhibited faster drug release behavior than reduction-insensitive micelles, which also led to higher cytotoxicity. The SPIO/DOX-loaded micelles demonstrated excellent MRI contrast enhancement, and the r2 relaxivity values of the SPIO/DOX-loaded micelles were up to 261.3 Fe mM-1 s-1. Consequently, these reduction-sensitive amphiphilic dextran derivatives are promising theranostic nanocarriers for MR imaging and chemotherapy.

We report the preparation and characterization of charged, amphiphilic block copolypeptides that form stable vesicles and micelles in aqueous solution. Specifically, we prepared and studied the aqueous self-assembly of a series of poly(L-lysine)-b-poly(L-leucine) block copolypeptides, KxL y, where x ranged from 20 to 80 and y ranged from 10 to 30 residues, as well as the poly(L-glutamatic acid)-b-poly(L-leucine) block copolypeptide, E60L20. Furthermore, the vesicular assemblies show dynamic properties, indicating a high degree of membrane fluidity. This characteristic provides stimuli-responsive properties to the vesicles and allows fine adjustment of vesicle size using liposome-based extrusion techniques. Vesicle extrusion also provides a straightforward means to trap solutes, making the vesicles promising biomimetic encapsulants.
