A light controlled cavitand wall regulates guest binding.

ABSTRACT: Here we report a cavitand with a photochemical switch as one of the container walls. The azo-arene switch undergoes photoisomerization when subjected to UV light producing a self-fulfilled cavitand. This process is thermally and photochemically reversible. The reported cavitand binds small molecules and these guests can be ejected from the cavitand through this photochemical process.

Guest recognition in a partially bridged deep cavitand.

Project description:The synthesis of a new deep cavitand partially bridged via disulfide bonds is described. Its thermodynamic and kinetic complexation parameters are compared with those of an unbridged analogue. The disulfide bridges cause deviations in ?H and ?S but result in only small differences in ?G of complexation. The bridges increase the activation barrier for guest dissociation and lead to complexes with enhanced kinetic stability.

Lipid bilayer environments control exchange kinetics of deep cavitand hosts and enhance disfavored guest conformations.

Project description:The effects on the molecular recognition properties of water-soluble deep cavitand hosts upon embedding them in phosphocholine lipid bilayer environments have been studied by 2D NMR experiments. By employing suitable guests containing 19F or 13C nuclei that can be encapsulated inside the host, 2D EXSY NMR experiments can be used to analyze and compare the in/out guest exchange rates in aqueous solution, isotropically tumbling micelles, or magnetically ordered bicelles. These analyses show that embedding the deep cavitands in lipid bilayers slows the guest exchange rate, due to the lipids acting as a "compression sleeve" around the host, restricting guest egress. This effect also enhances guest conformations in the host that are not observed in free solution, such as axial cyclohexane conformers and ketone hydrates.

Crystal structure of a host-guest complex between mephedrone hydro-chloride and a tetra-phospho-nate cavitand.

Project description:A new supra-molecular complex (I) between the tetra-phospho-nate cavitand Tiiii[C3H7,CH3,C6H5] [systematic name: 2,8,14,20-tetra-propyl-5,11,17,23-tetra-methyl-6,10:12,16:18,22:24,4-tetra-kis-(phenyl-phospho-nato-O,O')resorcin[4]arene] and mephedrone hydro-choride {C11H16NO+·Cl-; systematic name: meth-yl[1-(4-methyl-phen-yl)-1-oxopropan-2-yl]aza-nium chloride} has been obtained and characterized both in solution and in the solid state. The complex of general formula (C11H16NO)@Tiiii[C3H7,CH3,C6H5]Cl·CH3OH or C11H16NO+·Cl-·C68H68O12P4·CH3OH, crystallizes in the monoclinic space group P21/c with one lattice methanol mol-ecule per cavitand, disordered over two positions with occupancy factors of 0.665?(6) and 0.335?(6). The mephedrone guest inter-acts with the P=O groups at the upper rim of the cavitand through two charge-assisted N-H?O hydrogen bonds, while the methyl group directly bound to the amino moiety is stabilized inside the ? basic cavity via cation?? inter-actions. The chloride counter-anion is located between the alkyl legs of the cavitand, forming C-H?Cl inter-actions with the aromatic and methyl-enic H atoms of the lower rim. The chloride anion is also responsible for the formation of a supra-molecular chain along the b-axis direction through C-H?Cl inter-actions involving the phenyl substituent of one phospho-nate group. C-H?O and C-H?? inter-actions between the guest and adjacent cavitands contribute to the formation of the crystal structure.

Host-guest supra-molecular inter-actions between a resorcinarene-based cavitand bearing a -COOH moiety and acetic acid.

Project description:The cavitand 5,11,17,23-tetra-methyl-4,24:6,10:12,16:18,22-tetra-kis-(methyl-enedi-oxy)resorcin[4]arene functionalized at the upper rim with a carb-oxy-lic acid group, CavCOOH-in, of chemical formula C37H32O10, was synthesized in order to study its supra-molecular inter-actions with acetic acid in the solid state. Crystals suitable for X-ray diffraction analysis were obtained by slow evaporation of a di-chloro-methane-acetone solution of CavCOOH-in, to which glacial acetic acid had been added. The resulting compound, C37H32O10·2C2H4O2 (1) crystallizes in the space group P and its asymmetric unit consists of one mol-ecule of cavitand and two mol-ecules of acetic acid, one of which is encapsulated inside the aromatic cavity and disordered over two positions with a refined occupancy ratio of 0.344 (4):0.656 (4). The guest inter-acts with the host primarily through its methyl group, which (in both orientations) forms C-H⋯π inter-actions with the benzene rings of the cavitand. The crystal structure of 1 is dominated by O-H⋯O and C-H⋯O hydrogen bonding due to the presence of acetic acid and of the carb-oxy-lic group functionalizing the upper rim. Further stabilization is provided by offset π-π stacking inter-actions between the aromatic walls of adjacent cavitands [inter-centroid distance = 3.573 (1) Å].

Blue Light Regulates Cell Wall Structure and Carbohydrate Metabolism of Soybean Hypocotyl.

Project description:Soybean stem elongation and thickening are related to cell wall composition. Plant morphogenesis can be influenced by blue light, which can regulate cell wall structure and composition, and affect stem growth and development. Here, using proteomics and metabolomics, differentially expressed proteins and metabolites of hypocotyls grown in the dark and under blue light were studied to clarify the effects of blue light on the cell wall structure and carbohydrate metabolism pathway of soybean hypocotyls. Results showed that 1120 differential proteins were upregulated and 797 differential proteins were downregulated under blue light treatment, while 63 differential metabolites were upregulated and 36 differential metabolites were downregulated. Blue light promoted the establishment of cell wall structure and composition by regulating the expression of both the enzymes and metabolites related to cell wall structural composition and nonstructural carbohydrates. Thus, under blue light, the cross-sectional area of the hypocotyl and xylem were larger, the longitudinal length of pith cells was smaller, elongation of the soybean hypocotyl was inhibited, and diameter was increased.

GCR1 and GPA1 coupling regulates nitrate, cell wall, immunity and light responses in Arabidopsis.

Project description:G-protein signaling components have been attributed many biological roles in plants, but the extent of involvement of G-protein coupled receptor 1 (GCR1) with the Gα (GPA1) remained unknown. To address this, we have performed transcriptomic analyses on Arabidopsis gpa1-5gcr1-5 double mutant and identified 656 differentially expressed genes (DEGs). MapMan and Gene Ontology analyses revealed global transcriptional changes associated with external stimulus, cell wall organization/biogenesis and secondary metabolite process among others. Comparative transcriptomic analyses using the single and double mutants of gcr1-5 and gpa1-5 identified 194, 139 and 391 exclusive DEGs respectively, whereas 64 DEGs were common to all three mutants. Further, pair wise comparison of DEGs of double mutant with single mutants of gcr1-5 or gpa1-5 showed about one-third and over half common DEGs, respectively. Further analysis of the DEGs exclusive to the double mutant using protein-protein interaction networks revealed molecular complexes associated with nitrate and light signaling and plant-pathogen interactions among others. Physiological and molecular validation of nitrate-response revealed the sensitivity of germination to low N in the double mutant and differential expression of nitrate transporter (and nitrate reductase in all three mutants). Taken together, GCR1 and GPA1 work in partnership as well as independently to regulate different pathways.

Light-responsive MXenegel via interfacial host-guest supramolecular bridging.

Project description:Living in the global-changing era, intelligent and eco-friendly electronic components that can sense the environment and recycle or reprogram when needed are essential for sustainable development. Compared with solid-state electronics, composite hydrogels with multi-functionalities are promising candidates. By bridging the self-assembly of azobenzene-containing supramolecular complexes and MXene nanosheets, we fabricate a MXene-based composite gel, namely MXenegel, with reversible photo-modulated phase behavior. The MXenegel can undergo reversible liquefication and solidification under UV and visible light irradiations, respectively, while maintaining its conductive nature unchanged, which can be integrated into traditional solid-state circuits. The strategy presented in this work provides an example of light-responsive conducting material via supramolecular bridging and demonstrates an exciting platform for functional soft electronics.

Multiaddressable molecular rectangles with reversible host-guest interactions: modulation of pH-controlled guest release and capture.

Project description:A series of multiaddressable platinum(II) molecular rectangles with different rigidities and cavity sizes has been synthesized by endcapping the U-shaped diplatinum(II) terpyridine moiety with various bis-alkynyl ligands. The studies of the host-guest association with various square planar platinum(II), palladium(II), and gold(III) complexes and the related low-dimensional gold(I) complexes, most of which are potential anticancer therapeutics, have been performed. Excellent guest confinement and selectivity of the rectangular architecture have been shown. Introduction of pH-responsive functionalities to the ligand backbone generates multifunctional molecular rectangles that exhibit reversible guest release and capture on the addition of acids and bases, indicating their potential in controlled therapeutics delivery on pH modulation. The reversible host-guest interactions are found to be strongly perturbed by metal-metal and ?-? interactions and to a certain extent, electrostatic interactions, giving rise to various spectroscopic changes depending on the nature of the guest molecules. Their binding mode and thermodynamic parameters have been determined by 2D NMR and van't Hoff analysis and supported by computational study.

Exploring pH Dependent Host/Guest Binding Affinities.

Project description:When the electrostatic environment surrounding binding partners changes between unbound and bound states, the net uptake or release of a proton is possible by either binding partner. This process is pH-dependent in that the free energy required to uptake or release the proton varies with pH. This pH-dependence is typically not considered in conventional free energy methods where the use of fixed protonation states is the norm. In the present paper, we apply a simple two-step approach to calculate the pH-dependent binding free energy of a model cucubit[7]uril host/guest system. By use of λ-dynamics with an enhanced sampling protocol, adaptive landscape flattening, pKa shifts and reference binding free energies upon complexation were determined. This information enables the construction of pH-dependent binding profiles that accurately capture the pKa shifts and reproduce binding free energies at the different pH conditions that were observed experimentally. Our calculations illustrate a general framework for computing pH-dependent binding free energies but also point to some issues in modeling the molecular charge distributions within this series of molecules with CGenFF. However, by introducing some minor charge modifications to the CGenFF force field, we saw significant improvement in accuracy of the calculated pKa shifts.
