Nickel-Catalyzed Decarbonylative Cycloaddition of Benzofuran-2,3-diones with Alkynes to Flavones

Using dppe as the ligand, the Nickel-catalyzed decarbonylative cycloaddition of benzofuran-2,3-diones with alkynes was established, and a variety of functional flavones were synthesized in 65–99% yields. Terminal alkynes with substituted phenyl groups and internal alkynes such as aryl acyl acetylenes and diphenylacetylenes are suitable for this reaction. The effects of bases on the reactions of different types of alkyne substrates were also investigated and discussed. (Figure presented.).

CELL SURFACE RECEPTOR BINDING COMPOUNDS AND CONJUGATES

The present disclosure provides a class of compounds including a ligand moiety that specifically binds to a cell surface receptor, such as a mannose-6-phosphate receptor (M6PR) or a cell surface asialoglycoprotein receptor (ASGPR). The cell surface M6PR or ASGPR binding compounds can trigger the receptor to internalize into the cell a bound compound. The ligand moieties of this disclosure can be linked to a variety of moieties of interest without impacting the specific binding to, and function of, the cell surface receptor, e.g., M6PR or ASGPR. Also provided are compounds that are conjugates of the ligand moieties linked to a biomolecule, such as an antibody, which conjugates can harness cellular pathways to remove specific proteins of interest from the cell surface or from the extracellular milieu. Also provided are methods of using the conjugates to target a polypeptide of interest for sequestration and/or lysosomal degradation.

Influence of functional groups on the self-assembly of liquid crystals

Functional groups in the molecule play an important role in the molecular organization process. To reveal the influence of functional groups on the self-assembly at interface, herein, the self-assembly structures of three liquid crystal molecules, which only differ in the functional groups, are explicitly characterized by using scanning tunneling microscopy (STM). The high-resolution STM images demonstrate the difference between the supramolecular assembly structures of three liquid crystal molecules, which attribute to the hydrogen bonding interaction and π-π stacking interaction between different functional groups. The density functional theory (DFT) results also confirm the influence of these functional groups on the self-assemblies. The effort on the self-assembly of liquid crystal molecules at interface could enhance the understanding of the supramolecular assembly mechanism and benefit the further application of liquid crystals.

Imidazolinium-based Multiblock Amphiphile as Transmembrane Anion Transporter

Transmembrane anion transport is an important biological process in maintaining cellular functions. Thus, synthetic anion transporters are widely developed for their biological applications. Imidazolinium was introduced as anion recognition site to a multiblock amphiphilic structure that consists of octa(ethylene glycol) and aromatic units. Ion transport assay using halide-sensitive lucigenin and pH-sensitive 8-hydroxypyrene-1,3,6-trisulfonate (HPTS) revealed that imidazolinium-based multiblock amphiphile (IMA) transports anions and showed high selectivity for nitrate, which plays crucial roles in many biological events. Temperature-dependent ion transport assay using 1,2-dipalmitoyl-sn-glycero-3-phosphocholine (DPPC) indicated that IMA works as a mobile carrier. 1H NMR titration experiments indicated that the C2 proton of the imidazolinium ring recognizes anions via a (C?H)+???X? hydrogen bond. Furthermore, all-atom molecular dynamics simulations revealed a dynamic feature of IMA within the membranes during ion transportation.

A Bimetallic Metal–Organic Framework Encapsulated with DNAzyme for Intracellular Drug Synthesis and Self-Sufficient Gene Therapy

Although chemotherapy is one of the most widely used cancer treatments, there are serious side effects, drug resistance, and secondary metastasis. To address these problems, herein we designed a bimetallic metal–organic framework (MOF) encapsulated with DNAzyme for co-triggered in situ cancer drug synthesis and DNAzyme-based gene therapy. Once in cancer cells, MOFs would disassemble and liberate copper ions, zinc ions, and DNAzyme under the acidic environment of lysosomes. Copper ions can catalyze the synthesis of the chemotherapeutic drug through copper-catalyzed azide–alkyne cycloaddition (CuAAC) reaction after being reduced to CuI; zinc ions act as the cofactor to activate the cleavage activity of DNAzyme. The anticancer drug is synthesized intracellularly and can kill cancer cells on site to minimize side effects to normal organisms. The activated DNAzyme starts gene therapy to inhibit tumor proliferation and metastasis by targeting and cleaving oncogene substrates.

Dynamics of Hydrogen Bonding in Three-Component Nanorotors

The dynamics of hydrogen bonding do not only play an important role in many biochemical processes but also in Nature's multicomponent machines. Here, a three-component nanorotor is presented where both the self-assembly and rotational dynamics are guided by hydrogen bonding. In the rate-limiting step of the rotational exchange, two phenolic O-H–N,N(phenanthroline) hydrogen bonds are cleaved, a process that was followed by variable-temperature 1H NMR spectroscopy. Activation data (ΔG≠298=46.7 kJ mol?1 at 298 K, ΔH≠=55.3 kJ mol?1, and ΔS≠=28.8 J mol?1 K?1) were determined, furnishing a rotational exchange frequency of k298=40.0 kHz. Fully reversible disassembly/assembly of the nanorotor was achieved by addition of 5.0 equivalents of trifluoroacetic acid (TFA)/1,8-diazabicyclo[5.4.0]undec-7-ene (DBU) over three cycles.
