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.

Multi-drug delivery focuses on different signaling pathways in cancer cells that have synergistic anti-proliferative effects. In this study, we developed multi-prodrug nanocarriers (MPDNCs) consisting of poly (l-lysine)-carboxylate PTX (PLL-PTX) and hyaluronic acid-conjugated GEM (HA-GEM) for CD44-targeted synergistic biliary cancer therapy. An invitro study of cell viability and mRNA expression levels and an invivo study showed that MPDNCs more effectively inhibit proliferation in CD44-overexpressing cancer cells (HuCCT1) than in cells with lower CD44 expression (SCK) by synergistically inducing apoptosis. Consequently, these results demonstrate that MPDNCs are prodrugs with synergistic cancer therapeutic efficacy and effective cellular uptake at target cells compared to free drugs, indicating their strong potential as efficient multi-drug-carrying nano-platforms for cancer treatment.

Two thermo- and pH-sensitive polypeptide-based copolymers, poly(N-isopropylacrylamide-co-N-hydroxymethylacrylamide)-b-poly(L-lysine) (P(NIPAAm-co-HMAAm)-b-PLL, P1) and poly(N-isopropylacrylamide-co-N- hydroxymethylacrylamide)-b-poly(glutamic acid) (P(NIPAAm-co-HMAAm)-b-PGA, P2), have been designed and synthesized by the ring-opening anionic polymerization of N-carboxyanhydrides (NCA) with amino-terminated P(NIPAAm-co-HMAAm). It was found that the block copolymers exhibit good biocompatibility and low toxicity. As a result of electrostatic interactions between the positively charged PLL and negatively charged PGA, P1 and P2 formed polyion complex (PIC) micelles consisting of polyelectrolyte complex cores and P(NIPAAm-co-HMAAm) shells in aqueous solution. The thermo- and pH-sensitivity of the PIC micelles were studied by UV/Vis spectrophotometry, dynamic light scattering (DLS), and transmission electron microscopy (TEM). Moreover, fluorescent PIC micelles were achieved by introducing two fluorescent molecules with different colors. Photographs and confocal laser scanning microscopy (CLSM) showed that the fluorescence-labeled PIC micelles exhibit thermo- and pH-dependent fluorescence, which may find wide applications in bioimaging in complicated microenvironments.

Peptides of homochiral alpha- aminoxy acids of nonpolar side chains can form a 1.88-helix. In this paper, we report the conformational studies of alpha- aminoxy peptides 1-3, which have functionalized side chains, in both non- polar and polar solvents. 1H NMR, XRD, and FTIR absorption studies confirm the presence of the eight-membered-ring intramolecular hydrogen bonds (the N-O turns) in nonpolar solvents as well as in methanol. CD studies of peptides 1-3 in different solvents indicate that a substantial degree of helical content is retained in methanol and acidic aqueous buffers. The introduction of functionalized side chains in alpha-aminoxy peptides provides opportunities for designing biologically active peptides.

We developed a method in preparing size-controllable gold nanoparticles (Au NPs, 2-6 nm) capped with glutathione by varying the pH (between 5.5 and 8.0) of the solution before reduction. This method is based on the formation of polymeric nanoparticle precursors, Au(I)-glutathione polymers, which change size and density depending on the pH. Dynamic light scattering, size exclusion chromatography, and UV-vis spectroscopy results suggest that lower pH values favor larger and denser polymeric precursors and higher pH values favor smaller and less dense precursors. Consequently, the larger precursors led to the formation of larger Au NPs, whereas smaller precursors led to the formation of smaller Au NPs. Using this strategy, Au NPs functionalized with nickel(II) nitriloacetate (Ni-NTA) group were prepared by a mixed-ligand approach. These Ni-NTA functionalized Au NPs exhibited specific binding to 6x-histidine-tagged Adenovirus serotype 12 knob proteins, demonstrating their utility in biomolecular labeling applications.

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.

Enhanced delivery of biodegradable mPEG-PLGA-PLL nanoparticles loading Cy3-labelled PDGF-BB siRNA by UTMD to rat retina

We investigated the efficacy and safety of ultrasound (US)-targeted microbubble (MB) destruction (UTMD)-enhanced delivery of monomethoxypoly(ethylene glycol)-poly(lactic-co-glycolic acid)-poly-l-lysine (mPEG-PLGA-PLL) nanoparticles (NPs) loading Cy3-labelled platelet-derived growth factor BB (PDGF-BB) siRNA to rat retina in vivo. Eighty Wistar rats were divided into five groups (G). The right eyes, respectively, received an intravitreal injection as follows: normal saline (NS) (G1), NPs and NS (G2), NPs and MBs (G3), NPs and NS (G4) and NPs and MBs (G5). In G4 and G5, the eyes were exposed to US for 5 mins. Twenty-four hours after transfection, the uptake and distribution of Cy3-labelled siRNA in rat retina were observed by fluorescent microscope. The percentage of Cy3-labelled siRNA-positive cells was evaluated by flow cytometer. The levels of PDGF?BB mRNA in retinal pigment epithelium (RPE) cells and secreted PDGF?BB proteins were also measured. Hematoxylin and eosin staining and frozen sections were used to observe tissue damage. Our results showed that the number of Cy3-labelled siRNA-positive cells in G5 was significantly higher than those of the other groups (P<0.05 for all comparisons). The maximum efficiency of siRNA uptake in neural retina was 18.22¡À1.67%. In G4 and G5, a small number of Cy3-labelled siRNA-positive cells were also detected in the pigmented cell layer of the retina. NPs loading siRNA delivered with UTMD could more effectively down-regulate the mRNA and protein expression of PDGF?BB than NPs plus US (P=0.014 and P=0.007, respectively). Histology showed no evident tissue damage after UTMD-mediated NPs loading siRNA transfection. UTMD could be used safely to enhance the delivery of mPEG-PLGA-PLL NPs loading siRNA into rat retina. We¡¯ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, the role of 1202-04-6, and how the biochemistry of the body works.Reference of 1202-04-6
