A simple method to fabricate redox-responsive composite hydrogel films via incorporating chitosan (CS) micro spheres into carboxymethyl cellulose (CMC) hydrogel using a di-sulphide cross-linker cystamine dihydrochloride (CYS) have done in this paper. Dual drugs, an anticancer, 5-Fluorouracil (5-FU) and an antibiotic, Tetracycline Hydrochloride (TH) were used as model drugs. The prepared composite hydrogel films were characterized using FTIR, SEM, rheology measurement, mechanical and swelling tests. Our results showed that the well dispersed spherical CS microspheres endowed hydrogel film increased mechanical properties and swellability. In vitro drug release displayed an accelerated release under weak acidic or reducing media. The in vitro cytotoxicity and cell apoptosis studies showed the drug-loaded composite film caused enhanced inhibition to HepG2 cells in presence of glutathione (GSH). Moreover, the film has exhibited excellent antimicrobial efficacy against E.coli and Staphylococcus aureus. Therefore, our simple and effective dual drug-loaded system has the potential to be used for cancer therapy in the future. (C) 2019 Elsevier B.V. All rights reserved.

Sequence specific molecules with high folding ability (i.e., foldamers) can be used to precisely control the distribution and projection of side chains in space and have recently been introduced as tailored systems for delivering nucleic acids into cells. Designed oligourea sequences with an amphipathic distribution of Arg- and His-type residues were shown to form tight complexes with plasmid DNA, and to effectively promote the release of DNA from the endosomes. Herein, we report the synthesis of new cell-penetrating foldamer sequences in which the foldamer segment is conjugated via a reducible disulfide bond to a ligand that binds cell-surface expressed nucleoproteins with the idea that this system could facilitate both assemblies with nucleic acids and cell entry. This new system was evaluated for delivery of DNA in several cell lines and was found to compare favorably with all comparators tested (DOTAP and b-PEI as well as a number of known cell penetrating peptides) in various cell lines and particularly in culture medium containing up to 50% of serum. These results suggest that this dual molecular platform which is long lasting and noncytotoxic could be of practical use for in vivo applications.

Isotactic polypropylene (PP) is one of the most popular plastics. However, the remarkably low surface energy of PP prevents the surface functionalization of PP. We studied the surface functionalization of PP by dip-coating with a maleic anhydride-grafted chlorinated polypropylene (MPO)/methacrylate-based terpolymer mixture. A methacrylate-based terpolymer (PMFP) was synthesized, which contained perfluoroalkyl (R-f)-conjugated monomers and poly(ethylene glycol)-conjugated monomers. Tape-peeling tests revealed that MPO successfully immobilized PMFP on a PP surface, although PMFP was less adhesive to PP. X-ray photoelectron spectroscopy (XPS), contact angle, and protein adsorption measurements revealed that the R-f groups and PEG chains in PMFP were segregated to the outermost surface of the dip-coated layer. The surface segregation of these moieties produced a low-fouling surface on the PP substrate. In addition, we synthesized a terpolymer that contained R-f groups and PEG chains with carboxy groups at their termini (PMFB) and used it to dip-coat a PP substrate. The surface segregation of side chains in PMFB induced the presentation of carboxy groups at the outermost surface, which were used as reactive sites for enzyme immobilization.

Melphalan (MEL) is an effective chemotherapeutic agent for treatment of retinoblastoma (Rb) which is the most common childhood malignancy. However, the inherent cardiopulmonary toxicity and hazardous integration limit its therapeutic effect on RB. N-Acetylheparosan (AH), a natural heparin-like polysaccharide in mammals with long circulation effect and good biocompatibility, was linked by d-alpha-tocopherol acid succinate (VES) via and cystamine (CYS) to synthesize reduction-responsive N-acetylheparosan-CYS-Vitamin E succinate (AHV) copolymers. In addition, CYS was replaced by adipic acid dihydrazide (ADH) to obtain a control of non-reduction-responsive polymers N-acetylheparosan-ADH-Vitamin E succinate (ADV). MEL-loaded AHV micelles (MEL/AHV) as well as ADV micelles (MEL/ADV) were prepared with small particle size and high drug loading content. In vitro drug release showed that MEL/AHV micelles presented obvious reduction-triggered release behavior compared with MEL/ADV. In vitro antitumor effects were investigated using WERI-Rb-1 retinoblastoma cells. Cytotoxicity experiments showed that the IC50 of MEL/AHV was significantly lower than that of free MEL and MEL/ADV, suggesting that MEL/AHV enhanced the cytotoxicity against retinoblastoma cells. Furthermore, MEL/AHV micelles were more easily uptaken by multiple pathways compared with MEL/ADV and free MEL. Therefore, MEL/AHV might be a potential delivery system for enhanced delivery of melphalan to Rb cells. (C) 2019 Elsevier B.V. All rights reserved.

A multifunctional drug delivery system (MDDS) based on near-infrared (NIR) imaging was developed in various conformations for the accurate diagnosis and therapy of cancer. However, it remains challenging to develop an ideal structure for an MDDS with both exact and variable functionality. Herein, we report a fluorescence color-changeable branched-form heptamethine cyanine dye (PEG-4-CyP) that has both a simple structure and various functionality. The PEG-4-CyP was not only able to construct the nanoparticle (NP) structure by encapsulating DOX (PEG-4-CyP/DOX), but also showed change in the NIR fluorescence color by reacting with glutathione (GSH). The PEG-4-CyP/DOX was broken down in the redox microenvironment inside cancers because of the reduction reaction of PEG-4-CyP to GSH. As a result, the NP disruption, DOX release, and reactivity of PEG-4-CyP to GSH were visualized by NIR fluorescence color-change. Moreover, PEG-4-CyP/DOX showed an excellent chemophototherapeutic effect in cancer cells. This NIR fluorescence color-change strategy demonstrates the applicability of PEG-4-CyP as a novel MDDS able to provide a variety of information with a simple NP structure.

Many of new chemical discovered in pharmaceutical industry are hydrophobic compounds. Various techniques have been used to overcome solubility problems of hydrophobic drugs in aqueous media. In the meantime, dendrimers have been considered for sustainability, nanoscale size, high carry capacity, tunable terminal functional groups in terms of drug delivery and solubility. In this work, we have synthesized poly(propylene imine) (PPI) dendrimer up to fifth generation using reduction of nitrile groups after Michael addition and also, polyamidoamine (PAMAM) dendrimer up to fourth generation using Michael addition and amidation reactions. fourth and fifth generations of PPI dendrimer and fourth and third generations of PAMAM dendrimer in different concentrations were used to evaluate the solubility of two hydrophobic drugs (tetracycline and dexamethasone). Furthermore, cytotoxicity of dendrimers and dendrimers/drugs hybrids was studied. The results showed that with increasing concentrations and also the generation of dendrimers, the solubility of these two hydrophobic drugs was increased. Cytotoxicity study through MTT assay against Osteoblast-like cell line (MG-63 cells) showed that dendrimers were relatively cytotoxic where adding dexamethasone caused higher cytotoxicity. However, tetracycline showed no significant effect on cytotoxicity whereas prevented cell proliferation.

A series of isocyanate-free polyurethanes (NIPUs), showing an intrinsic thermo-healing performance, have been synthesized from sustainable vegetable oil-based cyclic carbonates and bio-based amines. The bio-based contents of the NIPUs are higher than 78%. Their thermo-mechanical and self-healing performances are tailored simply by varying the feed ratios of the amines employed. The biomass linoleic acid dimer-based diamine plays a positive role in maintaining the higher thermal stability and good elasticity of the prepared NIPUs, the cycloaliphatic isophorone diamine contributes to high tensile strength, and cysteine-derived disulfide-containing cystamine (CA) enhances the self-healing efficiency. The combination of intrinsic hydrogen bonds existed in the NIPU matrix with the dynamic exchange reactions of disulfide bonds and the enhanced flexibility of NIPU networks results in 98.1% self-healing efficiency at 25 degrees C. The contributions of disulfide bonds and hydrogen bonds to the healing efficiency were estimated by adjusting the composition of NIPUs, showing that the contribution of disulfide bonds to the healing ability is about 45.3% even at a low amount of CA (6.0 wt%).

A new kind of redox responsive nanoparticles was prepared through the modification and crosslinking reaction of xanthan gum. The nanoparticles had regular spherical shapes with diameters ranging from 110 to 180 nm. The nanoparticles showed good redox responsiveness. Doxorubicin (DOX) was loaded in the nanoparticles via ionic interaction with SO3-, for increasing the drug loading rate and avoiding drug leakage. The in vitro drug release could be controlled by pH and reduction conditions simulated to the internal environment of tumor cells. The nanoparticles were biocompatible and could be potentially applied as anti-cancer drug vehicles for targeted release.
