Nanoparticles with active-targeting and stimuli-responsive behavior are a promising class of engineered materials able to recognize the site of cancer disease, targeting the drug release and limiting side effects in the healthy organs. In this work, new dual pH/redox-responsive nanoparticles with affinity for folate receptors were prepared by the combination of two amphiphilic dextran (DEX) derivatives. DEXFA conjugate was obtained by covalent coupling of the polysaccharide with folic acid (FA), whereas DEXssPEGCOOH derived from a reductive amination step of DEX was followed by condensation with polyethylene glycol 600. After self-assembling, nanoparticles with a mean size of 50 nm, able to be destabilized in acidic pH and reducing media, were obtained. Doxorubicin was loaded during the self-assembling process, and the release experiments showed the ability of the proposed system to modulate the drug release in response to different pH and redox conditions. Finally, the viability and uptake experiments on healthy (MCF-10A) and metastatic cancer (MDA-MB-231) cells proved the potential applicability of the proposed system as a new drug vector in cancer therapy.

A well-defined functional star polymer nanoparticle was prepared using an “ arm first” approach via RAFT polymerization. In this work, N-adamantylacrylamide and N-succinimidyl acrylate were copolymerized with N-isopropylacrylamide sucessfully. The obtained diblock copolymer regarded as an “ arm” endowed the star polymer with multiple conjugate functions. By adjusting the amount of crosslinking agent, the size and polydispersity of the star polymer were controlled. With the star polymer as the scaffold, a sequential multi-enzyme system was constructed, where HRP was placed in the inner layer through covalent conjugation, and b-cyclodextrin-modified GOx was assembled in the outer layer through hostguest recognition. More interestingly, the activity of the enzyme modified by b-cyclodextrin was improved. In addition to the enhanced thermal stability, this multienzyme system also exhibited a reduced Km value (from 2.18 mM to 0.39 mM) and an excellent substrate affinity. The specificity constant (Kcat/Km) for GOx in the star polymer@ HRP@ GOx system was 1.7-fold higher than that of the free HRP with free GOx system. This strategy will promote the development of biocatalysis reactions and biosensors as a promising method.

Polymer based core cross-linked nanoparticles (CCNPs) have generated a lot of interest as potential stimuli-responsive drug delivery systems. In the present work, we have synthesized smart redox-responsive water soluble polymeric CCNPs by cross-linking water-soluble PEG based copolymers with bis(acryloyl)cystamine via isoxazoline bond formation through a 1,3-dipolar cycloaddition reaction (click reaction) without using a copper catalyst, in a water-THF mixed solvent. The successful synthesis of CCNPs was confirmed by NMR, GPC and FT-IR measurements. Size distribution of the precursor copolymers and the CCNPs was determined by DLS measurement. AFM and FESEM images have confirmed globular morphology of these CCNPs. Their high stability in a physiological environment makes them effective as potent drug carriers with high loading capacity. MTT assays confirmed the biocompatibility of the synthesized CCNPs. Favourable cellular internalization of these DOX loaded CCNPs into cancer cells and redox-responsive release of DOX therefrom make these CCNP potentially smart vehicles to deliver anticancer drugs into cancer cells.

The utilization of agrochemicals in crop production is often inefficient due to lack of appropriate carriers, raising in the significant concerns of ecological environment and public health. To enhance the efficiency of agrochemical delivery, a novel cellulose-based hydrogel was constructed in this work by cross-linking dopamine (DA)-modified carboxymethyl cellulose (CMC) with cystamine (CYS) in the presence of Fe3+ ions. The hydrogels displayed reversible sol-gel transitions upon exposure to stimulation of changes in pH and redox, leading to the controllable release of model agrochemical (6-benzyladenine). Compared with single-triggered condition, the hydrogel doubled the cumulative release when co-triggered by pH and redox. The dynamic metal/catechol complexation and disulfide bonding coexist in the hydrogel networks, enabling occurrence of dynamic reaction under a variety of environmental conditions. The finite element method (FEM) was employed to simulate the hydrogel to provide a theoretical insight into the tested drug delivery. Benefitting from the reversibly cross linked networks and the excellent biodegradability of the hydrogels, we anticipate that this dual-responsive, polysaccharide-based hydrogel will offer diverse applications to reach the full potential in sustainable advancement of crop production.

The aim of this work was to obtain a novel onco-theranostic system for early diagnosis and improved chemotherapeutic outcome. Hybrid nanogels with magnetic and dual responsive properties were fabricated by covalently attaching superparamagnetic iron oxide nanoparticles (SPIONs) with a disulfide-modified alginate derivative, while simultaneously encapsulating the anticancer drug doxorubicin. The resulting nanogels exhibited magnetic-targeted characteristics, high drug loading content, co-triggered release behavior, high toxicity to tumor cells, low side effects to normal cells, and magnetic resonance imaging (MRI) functions. These findings proved that the hybrid nanogels have great potential as novel tumor-targeting nano-theranostic agents for simultaneous MRI imaging and efficient anti-tumor treatment.

Recommanded Product: 2,2′-Disulfanediyldiethanamine dihydrochloride. I found the field of Biochemistry & Molecular Biology; Chemistry very interesting. Saw the article Synthesis and Guest-Binding Properties of pH/Reduction Dual-Responsive Cyclophane Dimer published in 2021.0, Reprint Addresses Hayashida, O (corresponding author), Fukuoka Univ, Dept Chem, Fac Sci, Nanakuma 8-19-1, Fukuoka 8140180, Japan..

A water-soluble cyclophane dimer having two disulfide groups as a reduction-responsive cleavable bond as well as several acidic and basic functional groups as a pH-responsive ionizable group 1 was successfully synthesized. It was found that 1 showed pH-dependent guest-binding behavior. That is, 1 strongly bound an anionic guest, 6-p-toluidinonaphthalene-2-sulfonate (TNS) with binding constant (K/M-1) for 1:1 host-guest complexes of 9.6 x 10(4) M-1 at pH 3.8, which was larger than those at pH 7.4 and 10.7 (6.0 x 10(4) and 2.4 x 10(4) M-1, respectively), indicating a favorable electrostatic interaction between anionic guest and net cationic 1. What is more, release of the entrapped guest molecules by 1 was easily controlled by pH stimulus. Large favorable enthalpies (Delta H) for formation of host-guest complexes were obtained under the pH conditions employed, suggesting that electrostatic interaction between anionic TNS and 1 was the most important driving force for host-guest complexation. Such contributions of Delta H for formation of host-guest complexes decreased along with increased pH values from acidic to basic solutions. Upon addition of dithiothreitol (DTT) as a reducing reagent to an aqueous PBS buffer (pH 7.4) containing 1 and TNS, the fluorescence intensity originating from the bound guest molecules decreased gradually. A treatment of 1 with DTT gave 2, having less guest-binding affinity by the cleavage of disulfide bonds of 1. Consequently, almost all entrapped guest molecules by 1 were released from the host. Moreover, such reduction-responsive cleavage of 1 and release of bound guest molecules was performed more rapidly in aqueous buffer at pH 10.7.

In this study, reduction-sensitive self-assembled polymer nanoparticles based on poly (lactic-co-glycolic acid) (PLGA) and chondroitin sulfate A (CSA) were developed and characterized. PLGA was conjugated with CSA via a disulfide linkage (PLGA-ss-CSA). The critical micelle concentration (CMC) of PLGA-ss-CSA conjugate is 3.5 mu g/mL. The anticancer drug doxorubicin (DOX) was chosen as a model drug, and was effectively encapsulated into the nanoparticles (PLGA-ss-CSA/DOX) with high loading efficiency of 15.1%. The cumulative release of DOX from reduction-sensitive nanoparticles was only 34.8% over 96h in phosphate buffered saline (PBS, pH 7.4). However, in the presence of 20mM glutathione-containing PBS environment, DOX release was notably accelerated and almost complete from the reduction-sensitive nanoparticles up to 96h. Moreover, efficient intracellular DOX release of PLGA-ss-CSA/DOX nanoparticles was confirmed by CLSM assay in A549 cells. In vitro cytotoxicity study showed that the half inhibitory concentrations of PLGA-ss-CSA/DOX nanoparticles and free DOX against A549 cells were 1.141 and 1.825 mu g/mL, respectively. Therefore, PLGA-ss-CSA/DOX nanoparticles enhanced the cytotoxicity of DOX in vitro. These results suggested that PLGA-ss-CSA nanoparticles could be a promising carrier for drug delivery.
