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 surface chemistry of colloidal silica has tremendous effects on its properties and applications. Commonly the design of silica particles is based on their de novo synthesis followed by surface functionalization leading to tailormade properties for a specific purpose. Here, the design of robust precursor polymer-decorated silica nano- and microparticles is demonstrated, which allows for easy post-modification by polymer embedded thiolactone chemistry. To obtain this organic-inorganic hybrid material, silica particles (SiO2P) were functionalized via surface-initiated atom transfer radical polymerization (SI-ATRP) with poly(2-hydroxyethyl acrylate) (PHEA)-poly(thiolactone acrylamide (PThlAm) co-polymer brushes. Exploiting the versatility of thiolactone post-modification, a system was developed that could be used in three exemplary applications: 1) the straightforward molecular post-functionalization to tune the surface polarity, and therefore the dispersibility in various solvents; 2) the immobilization of metal nanoparticles into the polymer brushes via the in situ formation of free thiols that preserved catalytic activity in a model reaction; 3) the formation of redox-responsive, permeable polymer capsules by crosslinking the thiolactone moieties with cystamine dihydrochloride (CDH) followed by dissolution of the silica core.

Amphiphilic derivatives of (+/-)-trans-1,2-diselenane-4,5-diol (DSTox) decorated with long alkyl chains or aromatic substituents via ester linkages were applied as glutathione peroxidase (GPx)-like catalysts. The reduction of H2O2 with the diselenide catalysts was accelerated through a GPx-like catalytic cycle, in which the diselenide (Se-Se) bond was reduced to the diselenolate form ([Se-,Se-]) by coexisting dithiothreitol, and the generated highly active [Se-,Se-] subsequently reduced H2O2 to H2O retrieving the original Se-Se form. In the lipid peroxidation of lecithin/cholesterol liposomes induced by 2,2′-azobis(2-amidinopmpane) dihydrochloride (AAPH), on the other hand, the Se-Se form directly reduced lipid peroxide (LOOH) to the corresponding alcohol (LOH), inhibiting the radical chain reaction, to exert the antioxidative effect. Thus, the two GPx-like catalytic cycles can be switched depending on the peroxide substrates. Furthermore, hydrophilic compounds with no or short alkyl groups (C3) showed high antioxidative activities for the catalytic reduction of H2O2, while lipophilic compounds with long alkyl chains (C6-C14) or aromatic substituents were more effective antioxidants against lipid peroxidation. In addition, these compounds showed low cytotoxicity in cultured HeLa cells and exhibited sufficient anti-lipid peroxidative activities, suggesting their potentials as selenium-based antioxidative drugs.

The four-arm star copolymers poly(methacrylic acid)-poly(2-hydroxyethyl methacrylate-disulfide similar to)-poly(poly(ethylene glycol) methyl ether methacrylate) (4AS-PMAA(x)-(PHEMA-SS similar to)(y)-PPEGMA(z)) with four different block ratios were synthesized and could self-assembled into cross-linked polymer micelles for the exploration of the structure-property relationship. The cross-linked polymer micelles in aqueous solution had low critical micelle concentration (CMC) values (1.9-4.6 mg/L), which exhibited better stability than non-cross-linked micelles. The CMC value decreased with the increase of the length of inner PMAA core and hydrophobic PHEMA cross-linked middle layer. The blank and doxorubicin (DOX)-loaded micelles with different block ratios were prepared by dialysis with the particle sizes of 120-240 nm. The longer inner PMAA core and cross-linked middle layer enhanced the drug loading content (DLC) results and led to relatively bigger particle sizes of polymer micelles. The in vitro DOX release data revealed that DOX-loaded micelles had low DOX cumulative release percentages of 18-37% after 110 h at pH 7.4, but up to 83-90% when introducing reductant GSH at pH 5.0. The 4AS-PMAA(21.2)-(PHEMASS approximate to)(13.1)-PPEGMA(5.1) micelles with the longest PMAA core had the largest cumulative release of 90.1%. The DOX release process and mechanism of the micelles at different conditions fitted well with the semi-empirical equation. Overall, the results demonstrated that the block ratios and pH/redox-responsiveness of these four-arm star copolymers could be well-controlled and their self-assembled cross-linked micelles as anticancer drug carrier system could be improved by optimizing the different ratios.

The replacement of the opposing nitrogen atoms in 1,4,8,11-tetraazacyclotetradecane (cyclam) with two sulfur atoms in 1,8-dithia-4,11-diazacyclotetradecane (dithiacyclam) enables the electrochemical reduction of protons and CO(2)via the corresponding nickel(ii) complex at more positive potentials. In addition, a 10-fold enhancement in the proton reduction rate of [Ni(dithiacyclam)](2+) relative to [Ni(cylcam)](2+) was observed. The study provides vital insight into Nature’s choice of employing predominantly sulfur based ligand platforms in achieving biological proton and CO2 reductions.

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.

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.

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.

Introducing clickable groups onto polymer microspheres allows the microspheres to be facilely functionalized via a click reaction. In this report, we have synthesized monodisperse PMMA microspheres with clickable double bonds on the surface by one-step RAFT-assisted dispersion photopolymerization using a cyclohexyl-containing macro-RAFT agent as a stabilizer. This macro-RAFT agent, named P(THPAA-b-AA)-TTC, was synthesized by RAFT-mediated block copolymerization of a cyclohexyl-containing monomer (THPAA, obtained by esterification of cis-1,2,3,6-tetrahydrophthalic with 2-hydroxyethyl acrylate) and acrylic acid. The obtained microspheres were analyzed by H-1 NMR and Iodometric method, indicating that the content of carbon double bonds on the microspheres increased with increasing the amount of P(THPAA-b-AA)-TTC in the polymerization feed. We then used a thiolated biotin to perform the photo-click reaction with the cyclohexene double bond on the micro spheres, thereby attaching the biotin unit onto the microspheres. The biotinylated PMMA microspheres were found to be able to effectively immobilize fluorescein isothiocyanate streptavidin (FITC-SAv) via the specific adsorption of biotin to streptavidin, and thus exhibited clear fluorescence under confocal microscope. This study provides a convenient and feasible way to prepare surface-functionalized microspheres, which has great potential in biological applications as well as other fields.
