Abstract
Stimuli-responsive behaviors and controlled release in liposomes are pivotal in nanomedicine. To this end, we present an approach using a photoresponsive azobenzene nanocluster (AzDmpNC), prepared from azobenzene compounds through melting and aggregation. When integrated with liposomes, they form photoresponsive vesicles. The morphology and association with liposomes were investigated by using transmission electron microscopy. Liposomes loaded with calcein exhibited a 9.58% increased release after UV exposure. To gain insights into the underlying processes and elucidate the mechanisms involved. The molecular dynamic simulations based on the reactive force field and all-atom force field were employed to analyze the aggregation of isomers into nanoclusters and their impacts on phospholipid membranes, respectively. The results indicate that the nanoclusters primarily aggregate through π-π and T-stacking forces. The force density inside the cis-isomer of AzDmpNC formed after photoisomerization is lower, leading to its easier dispersion, rapid diffusion, and penetration into the membrane, disrupting the densification.

Abstract
AbstractVisible-light-responsive azobenzene derivative in which a functional group having cell membrane permeability and a fluorophore were bonded was synthesized. This compound localized to the hydrophobic part in the lipid membrane of the liposome, and when the light corresponding to the transition absorption of azobenzene was irradiated, morphological change of the liposome was observed. When this compound was loaded into living cells, this molecule localized to the lysosome and when irradiated with light of the same wavelength caused cell death. These observed changes are thought to be due to photoisomerization of azobenzene derivatives.

Abstract
The light-responsive nanochannel of rhodopsin gained wider research interest from its crucial roles in light-induced biological functions, such as visual signal transduction and energy conversion, though its poor stability and susceptibility to inactivation in vitro have limited its exploration. However, the fabrication of artificial nanochannels with the properties of physical stability, controllable structure, and easy functional modification becomes a biomimetic system to study the stimulus-responsive gating properties. Typically, light-responsive molecules of azobenzene (Azo), retinal, and spiropyran were introduced into nanochannels as photo-switches, which can change the inner surface wettability of nanochannels under the influence of light; this ultimately results in the photoresponsive nature of biomimetic nanochannels. Furthermore, the fine-tuning of their stimulus-responsive properties can be achieved through the introduction of host–guest systems generally combined with a non-covalent bond, and the assembling process is reversible. These host–guest systems have been introduced into the nanochannels to form different functions. Based on the host–guest system of light-responsive reversible interaction, it can not only change the internal surface properties of the nanochannel and control the recognition and transmission behaviors but also realize the controlled release of a specific host or guest molecules in the nanochannel. At present, macrocyclic host molecules have been introduced into nanochannels including pillararenes, cyclodextrin (CD), and metal–organic frameworks (MOFs). They are introduced into the nanochannel through chemical modification or host–guest assemble methods. Based on the changes in the light-responsive structure of azobenzene, spiropyran, retinal, and others with macrocycle host molecules, the surface charge and hydrophilic and hydrophobic properties of the nanochannel were changed to regulate the ionic and molecular transport. In this study, the development of photoresponsive host and guest-assembled nanochannel systems from design to application is reviewed, and the research prospects and problems of this photo-responsive nanochannel membrane are presented.

Abstract
Ultrafast water permeation in aquaporins is promoted by their hydrophobic interior surface. Polytetrafluoroethylene has a dense fluorine surface, leading to its strong water repellence. We report a series of fluorous oligoamide nanorings with interior diameters ranging from 0.9 to 1.9 nanometers. These nanorings undergo supramolecular polymerization in phospholipid bilayer membranes to form fluorous nanochannels, the interior walls of which are densely covered with fluorine atoms. The nanochannel with the smallest diameter exhibits a water permeation flux that is two orders of magnitude greater than those of aquaporins and carbon nanotubes. The proposed nanochannel exhibits negligible chloride ion (Cl-) permeability caused by a powerful electrostatic barrier provided by the electrostatically negative fluorous interior surface. Thus, this nanochannel is expected to show nearly perfect salt reflectance for desalination.

Abstract
We developed a photoreactive molecular glue, BPGlue-N3, which can provide a universal strategy to enhance the efficacy of DNA aptamers by temporary-to-permanent stepwise stabilization of their conjugates with target proteins. As a proof-of-concept study, we applied BPGlue-N3 to the SL1 (DNA aptamer)/c-Met (target protein) conjugate system. BPGlue-N3 can adhere to and temporarily stabilize this aptamer/protein conjugate multivalently using its guanidinium ion (Gu+) pendants that form a salt bridge with oxyanionic moieties (e.g., carboxylate and phosphate) and benzophenone (BP) group that is highly affinitive to DNA duplexes. BPGlue-N3 is designed to carry a dual-mode photoreactivity; upon exposure to UV light, the temporarily stabilized aptamer/protein conjugate reacts with the photoexcited BP unit of adhering BPGlue-N3 and also a nitrene species, possibly generated by the BP-to-N3 energy transfer in BPGlue-N3. We confirmed that SL1, covalently conjugated with c-Met, hampered the binding of hepatocyte growth factor (HGF) onto c-Met, even when the SL1/c-Met conjugate was rinsed prior to the treatment with HGF, and suppressed cell migration caused by HGF-induced c-Met phosphorylation.

Abstract
Nowadays, reversible friction regulation has become the focus of scientists in terms of the flexible regulatory structure of photosensitive materials and theories since this facilitates rapid development in this field. Meanwhile, as an external stimulus, light possesses great potential and advantages in spatiotemporal control and remote triggering. In this work, we demonstrated two photo-isomerized organic molecular layers, tetra-carboxylic azobenzene (NN4A) and dicarboxylic azobenzene (NN2A), which were selected to construct template networks on the surface of the highly oriented pyrolytic graphite (HOPG) to study the friction properties, corresponding to the arrangement structure of self-assembled layers under light regulation. First of all, the morphology of the self-assembled layers were characterized by a scanning tunneling microscope (STM), then the nanotribological properties of the template networks were measured by atomic force microscope (AFM). Their friction coefficients are respectively changed by about 0.6 and 2.3 times under light control. The density functional theory (DFT) method was used to calculate the relationship between the force intensity and the friction characteristics of the self-assembled systems under light regulation. Herein, the use of external light stimulus plays a significant role in regulating the friction properties of the interface of the nanometer, hopefully serving as a fundamental basis for further light-controlling research for the future fabrication of advanced on-surface devices.

Abstract
Clay nanosheets (CNSs) have been widely used in the design of nanocomposite biomaterials. CNSs display a disk-like morphology with strong negatively charged surfaces. It has been shown that guanidinium-containing molecules can bind CNSs through noncovalent salt-bridge interactions and thus serve as "molecular glues" for CNSs. Making use of the guanidinium side chain in arginine, here, we designed novel arginine-rich elastomeric proteins to engineer protein-CNS nanocomposite hydrogels. Our results showed that these arginine-rich proteins can interact with CNSs effectively and can cross-link CNSs into hydrogels. Rheological measurements showed that mechanical properties of the resultant hydrogels depended on the arginine content in the arginine-rich proteins as well as CNS/protein concentration. Compared with hydrogels constructed from CNSs or proteins alone, the novel protein-CNS nanocomposite hydrogels show much improved mechanical properties. Our work opens up a new avenue to engineer functional protein hydrogels for various applications.

Abstract
Nano-clays (NCs) as a representative type of nano-materials are a source of inspiration for design of new biomedical materials with excellent performances. Research has shown that guanidinium ions (Gu+) can form non-covalent salt-bridge interactions with NCs, serving as "molecular glue" in the fabrication of NC-based composites. However, synthesis of the Gu+-containing molecules is always not easy. Since the natural amino acid arginine (Arg) possesses Gu+, Arg could potentially be a replacement for the synthetic molecules. To prove this possibility, nano-composites were constructed by combining model anisotropic NCs with Arg-modified nano-hydroxyapatite (nHAP-Arg) and polyarginine (poly-Arg), respectively. Formation of molecular interactions between NCs and nHAP-Arg/poly-Arg was demonstrated by enhanced gelation behaviour of NCs. Through taking the unique advantage of Arg, this study can be readily implemented in constructing a variety of NC-based composites with diverse functionalities that are necessary for potential applications in tissue engineering and regenerative medicine.

Effect of replacing main-chain ureas with thiourea and guanidinium surrogates on the bactericidal activity of membrane active oligourea foldamers. Bioorg Med Chem 2017; 25:4245-4252.

Abstract
Membrane-active foldamers have recently emerged as potential mimics of antimicrobial peptides (AMPs). Amphiphilic cationic helical N,N'-linked oligoureas are one such class of AMP mimics with activities in vitro against a broad range of bacteria including Bacillus anthracis, a Gram-positive sporulating bacillus and causing agent of anthrax. Here we have used site-selective chemical modifications of the oligourea backbone to gain additional insight into the relationship between structure and function and modulate anthracidal activity. A series of analogues in which urea linkages at selected positions are replaced by thiourea and guanidium surrogates have been prepared on solid support and tested against different bacterial forms of B. anthracis (germinated spores and encapsulated bacilli). Urea→thiourea and urea→guanidinium replacements close to the negative end of the helix dipole led to analogues with increased potency and selectivity for B. anthracis versus mammalian cells.

Abstract
Water-soluble linear polymers GumBAn (m/n = 18/6, 12/12, and 6/18) with multiple guanidinium ion (Gu(+)) and boronic acid (BA) pendants in their side chains were synthesized as ATP-responsive modulators for enzyme activity. GumBAn polymers strongly bind to the phosphate ion (PO4(-)) and 1,2-diol units of ATP via the Gu(+) and BA pendants, respectively. As only the Gu(+) pendants can be used for proteins, GumBAn is able to modulate the activity of enzymes in response to ATP. As a proof-of-concept study, we demonstrated that trypsin (Trp) can be deactivated by hybridization with GumBAn. However, upon addition of ATP, Trp was liberated to retrieve its hydrolytic activity due to a higher preference of GumBAn toward ATP than Trp. This event occurred in a much lower range of [ATP] than reported examples. Under cellular conditions, the hydrolytic activity of Trp was likewise modulated.

Abstract
Water-soluble bioadhesive polymers bearing multiple guanidinium ion (Gu+) pendants at their side-chain termini (Glue n -BA, n = 10 and 29) that were conjugated with benzamidine (BA) as a trypsin inhibitor were developed. The Glue n -BA molecules are supposed to adhere to oxyanionic regions of the trypsin surface, even in buffer, via a multivalent Gu+/oxyanion salt-bridge interaction, such that their BA group properly blocks the substrate-binding site. In fact, Glue10-BA and Glue29-BA exhibited 35- and 200-fold higher affinities for trypsin, respectively, than a BA derivative without the glue moiety (TEG-BA). Most importantly, Glue10-BA inhibited the protease activity of trypsin 13-fold more than TEG-BA. In sharp contrast, m Glue27-BA, which bears 27 Gu+ units along the main chain and has a 5-fold higher affinity than TEG-BA for trypsin, was inferior even to TEG-BA for trypsin inhibition.

Abstract
The possibility to arrange biological molecules into ordered nanostructures is an important issue in nano- and biotechnology. Nature offers a wide range of molecular "bricks" (e.g., proteins, oligonucleotides, etc.) that spontaneously assemble into more complex hierarchical systems with unique functionalities. Such molecular building blocks can be also used for the construction of nanomaterials with peculiar properties (e.g., DNA origami). In some cases, molecular glues able to bind biomolecules and to induce their assembly can be used to control the final structure and properties in a convenient way. Here we provide molecular-level description of how molecular glues designed to stick to the surface of microtubules (MTs) can control and transform the α/β-tubulin assembly upon temperature decreasing. By means of all-atom molecular dynamics (MD) simulations, we compared the adhesion to the MT surface of three molecular glues bearing the same guanidinium ion surface adhesive groups, but having different architecture, i.e., linear or dendritic backbone. Our evidence demonstrates that the adhesive properties of the different molecular glues are dependent on the shape they assume in solution. In particular, adhesion data from our MD simulations explain how globular- or linear-like molecular glues respectively stabilize MTs or transform them into a well-defined array of α/β-tubulin rings at 15 °C, where MTs naturally depolymerize. The comprehension of the MT transformation mechanism provides a useful rationale for designing ad hoc molecular glues to obtain ordered protein nanostructures from different biological materials.

Abstract
The complexes [Ru(bpy)2(pyESO)](PF6)2 and [Os(bpy)2(pyESO)](PF6)2, in which bpy is 2,2'-bipyridine and pyESO is 2-((isopropylsulfinyl)ethyl)pyridine, were prepared and studied by (1)H NMR, UV-visible and ultrafast transient absorption spectroscopy, as well as by electrochemical methods. Crystals suitable for X-ray structural analysis were grown for [Ru(bpy)2(pyESO)](PF6)2. Cyclic voltammograms of both complexes provide evidence for S→O and O→S isomerization as these voltammograms are described by an ECEC (electrochemical-chemical electrochemical-chemical) mechanism in which isomerization follows Ru(2+) oxidation and Ru(3+) reduction. The S- and O-bonded Ru(3+/2+) couples appear at 1.30 and 0.76 V versus Ag/AgCl in propylene carbonate. For [Os(bpy)2(pyESO)](PF6)2, these couples appear at 0.97 and 0.32 V versus Ag/AgCl in acetonitrile, respectively. Charge-transfer excitation of [Ru(bpy)2(pyESO)](PF6)2 results in a significant change in the absorption spectrum. The S-bonded isomer of [Ru(bpy)2(pyESO)](2+) features a lowest energy absorption maximum at 390 nm and the O-bonded isomer absorbs at 480 nm. The quantum yield of isomerization in [Ru(bpy)2(pyESO)](2+) was found to be 0.58 in propylene carbonate and 0.86 in dichloroethane solution. Femtosecond transient absorption spectroscopic measurements were collected for both complexes, revealing time constants of isomerizations of 81 ps (propylene carbonate) and 47 ps (dichloroethane) in [Ru(bpy)2(pyESO)](2+). These data and a model for the isomerizing complex are presented. A striking conclusion from this analysis is that expansion of the chelate ring by a single methylene leads to an increase in the isomerization time constant by nearly two orders of magnitude.

Abstract
Adenylate kinase shows a conformational transition (OPEN and CLOSED forms) during substrate binding and product release to mediate the phosphoryl transfer between ADP and ATP/AMP. The protein motional characteristics will be useful to construct switching systems of fluorophore properties caused by the catalytic cycle of the enzyme. This paper demonstrates in situ reversible switching of a fluorophore property driven by the conformational transition of the enzyme. The pyrene-conjugated mutant adenylate kinase is able to switch the monomer/excimer emission property of pyrene on addition of ADP or P(1)P(5)-di(adenosine-5')pentaphosphate (Ap5A, a transition state analog). The observation under the dilute condition (~0.1 μM) indicates that the emission spectral change was caused by the motion of a protein molecule and not led by protein-protein interactions through π-π stacking of pyrene rings. The switching can be reversibly conducted by using hexokinase-coupling reaction. The fashion of the changes in emission intensities at various ligand concentrations is different between ADP, Mg(2+)-bound ADP, and Mg(2+)-bound Ap5A. The emission property switching is repeatable by a sequential addition of a substrate in a one-pot process. It is proposed that the property of a synthetic molecule on the enzyme surface is switchable in response to the catalytic cycle of adenylate kinase.
