Temperature Control of the Self-Assembly Process of 4-Aminoquinoline Amphiphile: Selective Construction of Perforated Vesicles and Nanofibers, and Structural Restoration Capability. Chemistry 2024; 30:e202400134. [PMID: 38361463 DOI: 10.1002/chem.202400134] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/14/2024] [Revised: 02/13/2024] [Accepted: 02/14/2024] [Indexed: 02/17/2024]
Abstract
The construction of diverse and distinctive self-assembled structures in water, based on the control of the self-assembly processes of artificial small molecules, has received considerable attention in supramolecular chemistry. Cage-like perforated vesicles are distinctive and interesting self-assembled structures. However, the development of self-assembling molecules that can easily form perforated vesicles remains challenging. This paper reports a lower critical solution temperature (LCST) behavior-triggered self-assembly property of a 4-aminoquinoline (4-AQ)-based amphiphile with a tetra(ethylene glycol) chain, in HEPES buffer (pH 7.4). This property allows to form perforated vesicles after heating at 80 °C (> LCST). The self-assembly process of the 4-AQ amphiphile can be controlled by heating at 80 °C (> LCST) or 60 °C (< LCST). After cooling to room temperature, the selective construction of the perforated vesicles and nanofibers was achieved from the same 4-AQ amphiphile. Furthermore, the perforated vesicles exhibited slow morphological transformation into intertwined-like nanofibers but were easily restored by brief heating above the LCST.

Abstract
In situ self-assembly of peptides into well-defined nanostructures represents one of versatile strategies for creation of bioactive materials within living cells with great potential in disease diagnosis and treatment. The intimate relationship between amino acid sequences and the assembling propensity of peptides has been thoroughly elucidated over the past few decades. This has inspired development of various controllable self-assembling peptide systems based on stimuli-responsive naturally occurring or non-canonical amino acids, including redox-, pH-, photo-, enzyme-responsive amino acids. This review attempts to summarize the recent progress achieved in manipulating in situ self-assembly of peptides by controllable reactions occurring to amino acids. We will highlight the systems containing non-canonical amino acids developed in our laboratory during the past few years, primarily including acid/enzyme-responsive 4-aminoproline, redox-responsive (seleno)methionine, and enzyme-responsive 2-nitroimidazolyl alanine. Utilization of the stimuli-responsive assembling systems in creation of bioactive materials will be specifically introduced to emphasize their advantages for addressing the concerns lying in disease theranostics. Eventually, we will provide the perspectives for the further development of stimulus-responsive amino acids and thereby demonstrating their great potential in development of next-generation biomaterials.

Abstract
Purpose A new approach to monitor drug release and image inflammatory reactions in vitro and in vivo based on FRET mechanism was reported. Methods In this study, mixed micelles containing a synthesized fluorescent donor DAN-PPS-mPEG and its quencher DAB-PPS-mPEG were prepared. Their stabilities, self-assembling and oxidation-responsiveness towards oxidants were tested in vitro and in vivo. Results The conjugated polymers were synthesized and the morphological change and the fluorescent spectra of the prepared micellar system were measured. After incubating the DAN/DAB-PPS-mPEG mixed micelles with stimulated L929 fibroblast cells, the result of confocal laser microscopy showed fluorescence restoration of the micelles. Furthermore, an acute inflammatory injury mouse model was used to test the micelles in vivo. The micelles showed its ability to visualize the inflammatory site in the abdomen of the mice. Conclusion The results confirmed that DAN/DAB-PPS-mPEG mixed micelles can respond to oxidants and release encapsulated cargos with corresponding fluorescence restoration, and visualize the inflammatory cells in vitro and inflammatory reactions in vivo.

Abstract
Supramolecular assemblies based on oligo(ethylene glycol) (OEG) building blocks are well-known for their neutral chemical property and thermal-responsive behavior. Here, the cyclic "CLOSED" and linear "OPEN" typologies of OEGs led to dramatic difference in the sensitivity to guanidinium-containing species. From thermodynamic studies, the association constant (Ka) between the "CLOSED" form amphiphile and guanidinium salt was determined to be 28.7 M-1, whereas there was no detectable binding affinity for the "OPEN" form. Therefore, considering ion specificity, the present results establish that crown ether derivatives with "CLOSED" and "OPEN" topologies provide an easy-to-access model pair with designed ion-recognition sites and special functional moieties and geometries (like the binding pockets of enzymes or ion channels in cellular members) that allow the manipulation of the intercrossed relationship between supramolecular solutes, waters, and guanidinium salts. These supramolecular forces in aqueous solution offered an alternative strategy to fabricate thermal-responsive systems in ionic medium.

Abstract
Organic selenides are famous for their coordination and catalytic functions in the organic phase, albeit challenging for aqueous medium. Herein, the combination of a hydrophilic body of crown ether and substitution of one oxygen atom with a selenium one provides a new type of design route for organic selenide entities with charming functions in aqueous solution. The selenacrown ether C9Se presented here intrinsically shows an amphiphile-like property. Its nanosphere structure in water readily expands the catalysis of organic selenide to aqueous substrates in thiol/disulfide conversion.

Abstract
Transient increase of reactive oxygen species (ROS) is vital for some physiological processes, whereas the chronic and sustained high ROS level is usually implicated in the inflammatory diseases and cancers. Herein, we report the innovative redox-responsive theranostic micellar nanoparticles that are able to load anticancer drugs through coordination and hydrophobic interaction and to fluorescently monitor the intracellular redox status. The nanoparticles were formed by the amphiphilic block copolymers composed of a PEG segment and a selenide-containing hydrophobic polycarbonate block with a small fraction of coumarin-based chromophore. Under the alternative redox stimulation that might be encountered in the physiological process of some healthy cells, these nanoparticles underwent the reversible changes in size, morphology, and fluorescence intensity. With the assistance of small model compounds, we clarified the chemistry behind these changes, that is, the redox triggered reversible transformation between selenide and selenoxide. Upon the monotonic oxidation similar to the sustained high ROS level of cancer cells, the nanoparticles could be disrupted completely, which was accompanied by the drastic decrease in fluorescence. Cisplatin and paclitaxel were simultaneously coloaded in the nanoparticles with a moderate efficacy, and the coordination between selenide and platinum improved the stability of the drug-loaded nanoparticles against dilution. The naked nanoparticles are cytocompatible, whereas the dual drug-loaded nanoparticles exhibited a concentration dependent and synergistic cytotoxicity to triple-negative breast cancer (TNBC) cells. Of importance, the drug-loaded nanoparticles are much more toxic to TNBC cells than to normal cells due in part to ROS overproduction in the former cell lines.

Abstract
A series of water-soluble tertiary amines (TAs) are introduced into an oil-in-water (O/W) emulsion stabilized by sodium oleate (NaOA). TAs convert into bicarbonate salts upon bubbling of CO2, which could induce the increase of ionic strength of the aqueous phase, form ion pairs with NaOA by electrostatic interaction, and finally result in demulsification. ζ-Potential, conductivity, pH value, 1H NMR, separation rate, and interfacial tension are applied to figure out the effects of number of tertiary amine groups and different positions of the hydroxyl group. TA with an increasing number of tertiary amine groups can further stabilize the O/W emulsion and accelerate the process of demulsification by bubbling CO2. More tertiary amine groups bring about a more stable emulsion and faster demulsification by bubbling CO2. The position of the hydroxyl group is a key factor affecting the solubility of the corresponding ion pair formed with NaOA. The better the water solubility, the slower the demulsification. The worse the water solubility of the ion pair, the more perfect the demulsification is. More importantly, water-soluble TA, with proper structure, could bring about perfect demulsification.

Abstract
Carbon dots (CDs) are new materials with applications in bioimaging, optical devices, catalysis, and many other fields. Their advantages, such as ease of large-scale preparation, low-costing precursors, highly tunable photoluminescence, satisfactory biocompatibility, and photostability against photobleaching, make them competitive alternatives to conventional semiconductor-based quantum dots and organic dyes. To overwhelm other luminescent materials in applications, their functionalities still need to be improved in spite of the abovementioned advantages. In recent years, it has been proven that heteroatom doping is an effective approach to improve the optical and electronic performance of CDs by tuning their carbon skeleton matrices and chemical structures. In this review, the development of non-metal-heteroatom-doped CDs, including heteroatom categories, preparation methods, and physicochemical properties, are discussed. Progressive trends in heteroatom-doped CDs are also discussed at the end of this review.

Abstract
Multiresponsive wormlike micelles (WLMs) remain a significant challenge in the construction of smart soft materials based on surfactants. Herein, we report the preparation of a viscoelastic wormlike micellar solution based on a new redox-responsive surfactant, sodium dodecylselanylpropyl sulfate (SDSePS), and commercially available benzyl tertiary amine (BTA) in the presence of CO2. In this system, SDSePS can be reversibly switched on (selenide) and off (selenoxide) by a redox reaction, akin to that previously reported for benzylselanyl or phenylselanyl surfactants. By alternately adding H2O2 and N2H4·H2O, WLMs can be reversibly broken and formed because of the transformation of the hydrophilic headgroup of SDSePS, originating from the reversible formation of selenoxide. Moreover, WLMs can also be switched on and off by cyclically bubbling CO2 and N2 because of the variation of the binding interaction between SDSePS and BTA, resulting from the reversible protonation of BTA. This interesting and unique multiresponsive behavior makes the current WLMs a potential candidate for smart control of the "sol-gel" transition or substantial thickening of solutions.

Abstract
At present, more and more researchers around the world are paying attention to stimuli-responsive surfactants. In this paper, we have reported a microemulsion prepared from the tertiary amine TMPDA (N,N,N',N'-tetramethyl-1,3-propanediamine) and the anionic surfactant SDS (sodium dodecyl sulphate), which has good carbon dioxide response characteristics. The molar ratio of TMPDA to SDS is 1 : 2. By introducing CO2 into the microemulsion that consists of SDS, TMPDA, n-hexane, n-butanol and water, the tertiary amine TMPDA molecules can be protonated to form quaternary ammonium species. The protonated tertiary amine TMPDA can be assembled with SDS by electrostatic interactions to form a pseudogemini surfactant (SDS-TMPDA-SDS). The pseudogemini surfactant can dissolve in the aqueous phase which makes the microemulsion break down eventually. By bubbling N2 after CO2 into the same system at 50 °C for 3 hours, the pseudogemini surfactant SDS-TMPDA-SDS disintegrates into SDS and TMPDA, respectively. At the same time, the microemulsion also recovers its initial state. Such a reversible transition could be repeated for several cycles from monophase to complete phase separation.

Abstract
Artificial enzymes capable of achieving tunable catalytic activity through stimuli control of enzymatic structure transition are of significance in biosensor and biomedicine research. Herein we report a novel smart glutathione peroxidise (GPx) mimic with modulatory catalytic activity based on redox-induced supramolecular self-assembly. First, an amphiphilic Fmoc-phenylalanine-based selenide was designed and synthesized, which can self-assemble into nanospheres (NSs) in aqueous solution. The NSs demonstrate extremely low GPx activity. Upon the oxidation of hydroperoxides (ROOH), the selenide can be quickly transformed into the selenoxide form. The change of the molecular structure induces complete morphology transition of the self-assemblies from NSs to nanotubes (NTs), resulting in great enhancement in the GPx catalytic activity. Under the reduction of GSH, the selenoxide can be further reversibly reduced back into the selenide; therefore the reversible switch between the NSs and NTs can be successfully accomplished. The relationship between the catalytic activity and enzymatic structure was also investigated. The dual response nature makes this mimic play roles of both a sensor and a GPx enzyme at the same time, which can auto-detect the signal of ROOH and then auto-change its activity to achieve quick or slow/no scavenging of ROOH. The dynamic balance of ROOH is vital in organisms, in which an appropriate amount of ROOH does benefit to the metabolism, whereas surplus ROOH can cause oxidative damage of the cell instead and this smart mimic is of remarkable significance. We expect that such a mimic can be developed into an effective antioxidant drug and provide a new platform for the construction of intelligent artificial enzymes with multiple desirable properties.
