Novel chitosan-cystamine-retinoic acid conjugate (CS-SS-RA) was synthesized and could self-assemble into redox-sensitive micelles in aqueous environment with low critical micelle concentration value. CS-SS-RA micelles were characterized with spherical shape, desirable particle size, negative zeta potential, high paclitaxel (PTX) loading and encapsulation efficiency and redox-sensitivity. Hemolysis and cytotoxicity studies proved the safety of CS-SS-RA micelles for intravenous administration. Cytotoxicity study against HepG2 cells and the growth inhibition study on three-dimensional multicellular tumor spheroids (MCTSs) revealed that PTX-loaded CS-SS-RA micelles exhibited higher antitumor activity than free PTX. The in vitro cellular uptake profiles of FITC-labeled CS-SS-RA micelles evaluated via confocal laser scanning microscopy and flow cytometry indicated that CS-SS-RA micelles could enhance cellular uptake efficiency of PTX, and their internalization by HepG2 cells were mediated by clathrin-mediated endocytosis and macropinocytosis. These results demonstrated that CS-SS-RA micelles could be developed as a promising platform for intracellular delivery of hydrophobic antitumor agents.

The reduced graphene oxide (rGO) modified natural rubber composite (NR) filled with high contents of silica was prepared by a wet compounding and latex mixing process using a novel interface modifier cystamine dihydrochloride (CDHC) with coagulation ability. CDHC acts as a coagulation agent through electrostatic interaction with rGO, SiO2, and latex rubber particles during the latex-based preparation process, while in the obtained silica/graphene/natural rubber composites, CDHC acts as an interface modifier. Compared with the composites prepared by the conventional mechanical mixing method, the dispersion of both rGO and SiO2 in the composites made by a wet compounding and latex mixing process is improved. As a result, the obtained silica/graphene/natural rubber composite prepared by this new method has good comprehensive properties. A Dynamic Mechanical Test suggests that the tan delta values of the composites at 60 degrees C decrease, indicating a low rolling resistance with increasing the graphene content at a low strain, but it increases at a higher strain. This unique feature for this material provides an advantage in the rubber tire application.

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.

Multidrug resistance (MDR) is a major reason for anticancer chemotherapy failure, and P-glycoprotein (P-gp) over-expressing on tumor cells is considered as the important target to overcome MDR. Emerging reports have showed that vitamin E (VE) can cause significant reversal of MDR due to inhibition of ATPase activity. Accordingly, we synthesized hyaluronic acid (HA) conjugated vitamin E succinate (VES) polymer, which can self-assemble into micelles and thus achieve high drug (paclitaxel (PTX) used as model drug) encapsulation as well as tumor accumulation owing to the enhanced permeability and retention (EPR) effect and HA active targeting ability. In addition, the linker between HA and VES utilized in this work was disulfide bond with reduction-sensitive property, which would respond to high glutathione (GSH) concentration in tumor cytoplasmic environment and trigger HA-CYS-VES polymer disassociation and drug release. In vitro, PTX loaded HA-CYS-VES demonstrated enhanced cytotoxicity, high apoptosis-inducing activities and reversal effects of PTX on MCF-7/Adr cells, compared to PTX. Also, cellular uptake and intracellular PTX accumulation tests displayed that PTX loaded HA-CYS-VES could more efficiently enter tumor cells and selectively release drug in cytosol so as to facilitate its function on microtubule. More importantly, PTX loaded HA-CYS-VES showed better tumor targeting ability, improved antitumor efficacy and low adverse effects on tumor-bearing mice. In conclusion, PTX loaded HA-CYS-VES exhibited a great potential for reversing MDR in anticancer chemotherapeutics.

In this paper, a novel redox-responsive nanoparticles has been designed for targeted delivery of docetaxel (DTX). Chondroitin sulfate (CS) was used to construct the nanoparticles due to the ability of tumor targeting through binding with CD44 receptor that overexpresses on the surfaces of various tumor cells. A redox-responsive small-molecular DTX prodrug was prepared through modifying with cystamine containing disulfide bonds (Cys-DTX). Then the DTX prodrug was grafted to the CS to construct the amphiphilic polymer (CS-ss-DTX). Further, Cys-DTX/CS-ss-DTX nanoparticles were formed by self-assembly of amphiphilic polymer and incorporation of free Cys-DTX prodrug. This category of nanosized DTX delivery system was expected for not only exhibiting high permeability and cytotoxicity of Cys-DTX prodrug, but also targeting transportation of encapsulated redox-responsive Cys-DTX prodrug. According to results of related researches on physicochemical properties and biological evaluation, the novel redox-responsive Cys-DTX/CS-ss-DTX nanoparticles increased amount of DTX released from the nanoparticles in reductive environment, improved permeability in tumor tissues, enhanced cytotoxicity and decreased side effects compared with free DTX. All of these results showed that this kind of Cys-DTX/CS-ss-DTX nanoparticles were worthy of being expectation in tumor chemotherapy in future.

The objective of this study was to synthesize and characterize cystamine dihydrochloride (CYS) crosslinked carboxymethyl cellulose/quaternized chitosan (CMC/HACC) composite hydrogel film. Firstly, the glycidyl-based quaternary ammonium chitosan derivative (HACC) was synthesized using nucleophilic substitution reaction. Then HACC was analyzed by FTIR, (HNMR)-H-1 spectra and the composite films at different blending ratio of CMC and HACC were studied by rheology measurement, mechanical and swelling tests. When the composite films were prepared under optimized conditions (CMC: HACC = 7:1), they showed excellent mechanical properties (with improved 93.3% tensile strength and 2.3% elongation at break) and swellability (equilibrium swelling ratio increased 270%) compared to pure CMC film. 5-Fluorouracil (5-FU) was used as drug model which has broad-spectrum anticancer properties. The 5-FU/CMC/HACC composite films showed redox and pH responsive of drug release properties along with well biocompatibility. The in vitro cytotoxicity and cell apoptosis studies showed the drug loaded composite films with obvious toxicity against HepG2 cells especially in the presence of GSH. In addition, CMC/HACC composite films showed good antibacterial against S. aureus and E. coli, while pure CMC film had no antimicrobial activities. It can be concluded that CMC/HACC composite films can be potentially used as targeted drug delivery system. (C) 2019 Elsevier B.V. All rights reserved.

Triptolide (TP) is one of the most common systemic treatments for inflammatory and immune diseases in China for centuries. However, TP exhibits some disadvantages, such as poor solubility in water, poor bioavailability, liver toxicity, renal toxicity, and other side effects. In order to reduce the adverse effects of TP, researchers have developed numerous strategies to address the adverse properties of triptolide. Nano-carrier-based triptolide delivery systems represent an emerging technology and are one of the strategies of nanomedicine that combines diagnostic and therapeutic applications in a single agent. In this approach, we developed a glutathione-activated carrier-free nanodrug of triptolide (CyssTPN) as a trackable drug delivery system. In this system, CyssTP self-assemble to form a carrier-free nanodrug, which possesses a monodisperse spherical morphology with hydrodynamic average sizes of about 50 nm. In addition, CyssTPN had good stability under different physiological conditions (pH, high salt, etc.). Apart from cellular imaging and cell uptake, CyssTPN can be tracked by the activation of TP ability in real-time and applied for cancer cell treatment efficiently. The result showed that CyssTPN could improve solubility, reduce the side effects, and increase the bioavailability of triptolide. It could also track triptolide activation timely and tumor therapy successfully.

In this study, an organic nanodrug delivery platform was constructed as a biocompatible cancer chemotherapeutic system, in which clinically approved sorafenib was loaded in the redox-responsive polymeric micelles, enabling dose-control release of drug to cancer tissues. In addition, visualizing tumor microenvironment changes is also essential for cancer chemotherapy, which can provide a priori and feedback control of drug delivery with reduced side effects. Therefore, second near-infrared window (NIR-II) dual-modal optical coherence tomography (OCT) and photoacoustic imaging were performed for real-time visualization of the tumor microenvironment changes in vivo during chemotherapy. In particular, the tumor angiogenesis, the vascular networks density change, and the quantitative total hemoglobin concentration and oxygen saturation of cancer tissues were carefully characterized for individually optimized cancer chemotherapy. It was discovered that the final tumor growth inhibition by dual-modal imaging-guided dose-control chemotherapy can be up to 94.6% during a 30-day treatment, which is much higher than the efficacy from presently utilized tumor treatment options. Herein, the combination of a redox-responsive theranostic agent and NIR-II dual-modal OCT and photoacoustic imaging paved a novel avenue both for guiding dosage control of antiangiogenic drugs to avoid toxic effects and for monitoring and inspecting tumor microenvironment changes while substantially enhancing tumor penetration and antitumor efficacy.

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.
