Abstract:

Herein, we present a facile synthesis of three azide-functionalized fluorophores and their covalent attachment as triazoles in Huisgen-type cycloadditions with model alkynes. Besides two ortho- and para-bromo-substituted benzaldehydes, the azide functionalization of a fluorene-based structure will be presented. The copper(I)-catalyzed azide–alkyne cycloaddition (CuAAC) of the so-synthesized azide-functionalized bromocarbaldehydes with terminal alkynes, exhibiting different degrees of steric demand, was performed in high efficiency. Finally, we investigated the photophysical properties of the azide-functionalized arenes and their covalently linked triazole derivatives to gain deeper insight towards the effect of these covalent linkers on the emission behavior.

Full text

Abstract:

Mesitylene was used as a core in seven new tritopic nitrogen containing linkers. Three of the linkers, each containing three nitrile groups, were obtained through Suzuki, Sonogashira and Heck-type coupling reactions. Next, these were converted to tetrazol-5-yl moieties by the cycloaddition of sodium azide to the nitrile functionalities. The last linker, containing three 1,2,3-triazol-4-yl moieties, was synthesized by the Huisgen cycloaddition of phenyl azide to the corresponding alkyne. The latter was obtained via a Corey–Fuchs reaction sequence from the previously reported formyl derivative. As the proof of concept for their potential in MOF design, one of the nitriles was used to build an Ag-based network.

Full text

Abstract:

Many clinically relevant therapeutic agents are formed from the conjugation of small molecules to biomolecules through conjugating linkers. In this study, two novel conjugating linkers were prepared, comprising a central coumarin core, functionalized with a dimaleimide moiety at one end and a terminal alkyne at the other. In our first design, we developed a protein labelling method that site-specifically introduces an alkyne functional group to a dicysteine target peptide tag that was genetically fused to a protein of interest. This method allows for the subsequent attachment of azide-functionalized cargo in the facile synthesis of novel protein-cargo conjugates. However, the fluorogenic aspect of the reaction between the linker and the target peptide was less than we desired. To address this shortcoming, a second linker reagent was prepared. This new design also allowed for the site-specific introduction of an alkyne functional group onto the target peptide, but in a highly fluorogenic and rapid manner. The site-specific addition of an alkyne group to a protein of interest was thus monitored in situ by fluorescence increase, prior to the attachment of azide-functionalized cargo. Finally, we also demonstrated that the cargo can also be attached first, in an azide/alkyne cycloaddition reaction, prior to fluorogenic conjugation with the target peptide-fused protein.

Abstract:

In this study, the synthesis of a telechelic linker bearing both azide and thiol functional groups was described. The reaction conditions were investigated to optimize the reaction yield. The product was analyzed using thin layer chromatography (TLC) and proton nuclear magnetic resonance (1H NMR). The employment of the obtained azide–thiol linker in heterogeneous polymer “click” functionalization was demonstrated for the first time, which was monitored by an online FT–IR method. The obtained telechelic azide–thiol linker is envisioned to be useful chemical tools to link macromolecular chains via orthogonal click reactions.

A new series of compounds was prepared from 6-methoxyquinolin-8-amine or its N-(2-aminoethyl) analogue via Ugi-azide reaction. Their linkers between the quinoline and the tert-butyltetrazole moieties differ in chain length, basicity and substitution. Compounds were tested for their antiplasmodial activity against Plasmodium falciparum NF54 as well as their cytotoxicity against L-6-cells. The activity and the cytotoxicity were strongly influenced by the linker and its substitution. The most active compounds showed good activity and promising selectivity.

Abstract:

The C-terminal tetrapeptide Gly-Pro-Ala-Thr of TMV coat protein was linked to poly- (L-lysine) of 37,300 and 80,000 daltons and to human serum albumin using different ratios of tetrapeptide to carrier. The new hydrazidosuccinyl HSc cross-linker effected the specific amino terminal attachment of the tetrapeptide by azide coupling. The synthetic peptide and its conjugates were controlled by various methods including 13C NMR and CD. Using a conjugate containing 74 tetrapeptide residues linked to poly(L-lysine) of 80,000 daltons for screening of monoclonal antibody by ELISA, 5.8 fmol of peptide were detectable. The serological and biological properties of the monoclonal antibody were assayed by indirect ELISA and by quantitative determination of virus neutralization. This neutralization could be reversed by the poly(L-lysine)-tetrapeptide conjugate but not by the free tetrapeptide.

Abstract:

In this article, a drug delivery system with a near-infrared (NIR) light-responsive feature was successfully prepared using a block copolymer poly(ethylene oxide)-b-poly(glycidyl methacrylate)-azide (PEO-b-PGMA-N3) and a cross-linker containing a Se-Se bond through “click” chemistry. Doxorubicin (DOX) was loaded into the core-cross-linked (CCL) micelles of the block copolymer along with indocyanine green (ICG) as a generator of reactive oxygen species (ROS). During NIR light exposure, ROS were generated by ICG and attacked the Se-Se bond of the cross-linker, leading to de-crosslinking of the CCL micelles. After NIR irradiation, the CCL micelles were continuously disrupted, which can be a good indication for effective drug release. Photothermal analysis showed that the temperature elevation during NIR exposure was negligible, thus safe for normal cells. In vitro drug release tests demonstrated that the drug release from diselenide CCL micelles could be controlled by NIR irradiation and affected by the acidity of the environment.

Abstract:

A set of 6- to 24-valent clusters was constructed with terminal deoxynojirimycin (DNJ) inhibitory heads through C6 or C9 linkers by way of Cu(I)-catalyzed azide-alkyne cycloaddition (CuAAC) reactions between mono- or trivalent azido-armed iminosugars and calix[8]arene scaffolds differing in their valency and their rigidity but not in their size. The power of multivalency to upgrade the inhibition potency of the weak DNJ inhibitor (monovalent DNJ Ki being at 322 and 188 µM for C6 or C9 linkers, respectively) was evaluated on the model glycosidase Jack Bean α-mannosidase (JBα-man). Although for the clusters with the shorter C6 linker the rigidity of the scaffold was essential, these parameters had no influence for clusters with C9 chains: all of them showed rather good relative affinity enhancements per inhibitory epitopes between 70 and 160 highlighting the sound combination of the calix[8]arene core and the long alkyl arms. Preliminary docking studies were performed to get insights into the preferred binding modes.

Abstract:

We determined the interaction sites of the cytochrome P450's protein-partners: 2B4 (d-2B4) and NADPH-cytochrome P450 of reductase (d-Fp). While in operation, these proteins are forming the complexes. We used 4-4'-dithio(bisphenyl)azide linker for non-specific covalent coupling of d-2B4 complexes with d-Fp in Emulgen-913 - monomerized system. Covalently-linked peptides in this complex were identified with ESI-MS/MS. Several sites of these proteins' binding with each other were revealed. Based on them, a model of intermolecular protein interactions was created. The model includes 5 cross-linker-stabilized contact sites of d-2B4 with d-Fp involving the following peptides of d-2B4 and d-Fp: 1) d-2B4423-433 и d-Fp 102-109; 2) d-2B4324-336 и d-Fp570-585; 3) d-2B4327-336 и d-Fp452-464; 4) d-2B4 192-197 и d-Fp456-464; 5) d-2B4 134-139 и d-Fp406-425.Herein, in the latter two cases, the peptides of d-Fp are located in their inter-domain slit and stabilize protein-protein complex via nanoprobe cross-linker; therefore, the formation of d-2B4/d-Fp complexes in these sites may involve aminoacid residues d-Fp456-464 and d-Fp406-425 surrounding inter-domain slit.

A new CuII–azide complex, {(C4H12N2)[Cu5(N3)12]·4H2O}n, has been synthesized by the reaction of piperazine, Cu(OAc)2·2H2O (OAc is acetate) and NaN3. In the structure, μ2-1,1- and μ3-1,1,1-azide anions bridge five CuIIcations to form a linear pentanuclear cluster unit, which is further linked by μ2-1,1- and μ2-1,3-azide anions to form a two-dimensional condensed [Cu5(N3)12]nlayer. The diprotonated piperazine and the solvent water molecules are hydrogen bonded to the coordination layers to form a three-dimensional supramolecular network.

Abstract:

2-Azidomethyl-5-ethynylfuran, a new ambivalent compound with both azide and alkyne moieties that can be used as a self-clickable monomer, is synthesized starting directly from renewable biomass. The reactivity of the azide group linked to furfural is tested via the efficient preparation of a broad range of furfural-containing triazoles in good to excellent yields using a ‘green’ copper(I)-catalyzed azide–alkyne cycloaddition procedure. Access to new bio-based chemicals and oligomeric materials via a click-chemistry approach is also demonstrated using this bio-derived building block.

Abstract:

Fifteen hybrid-mutant lines and two direct mutant lines were studied in terms to their technological quality in 2000 and 2001 vegetation years. The hybrid-mutant lines were produced using chemical mutagen sodium azide at a concentration of 1mM on F<sub>2</sub> seeds. For parent cultivars, promising and well adapted Bulgarian and foreign common winter wheat cultivars were used. The direct mutant lines were obtained by gamma-irradiation and sodium azide treatment of dry seed from cultivars. The differences of the following three characteristics: quality index, softening of dough and energy for dough deformation (W) of MX 77/14 compared to the total mean value are positive and statistically significant. Crude protein, softening of dough, and energy for dough deformation (W) of MX 84/37 are also significantly different in relation to the total mean value. Both wheat lines refer to the group of common winter wheat with very good technological quality. This fact was confirmed of higher values of energy for dough deformation (W), than strong wheat cultivar Pobeda.

Abstract:

Introducing new physicochemical properties into proteins through genetically encoded Uaa (unnatural amino acid) incorporation can lead to the generation of proteins with novel properties not normally accessible with the 20 natural amino acids. Phenyl azide chemistry represents one such useful addition to the protein repertoire. Classically used in biochemistry as a non-specific photochemical protein cross-linker, genetically encoding phenyl azide chemistry at selected residues provides more powerful routes to post-translationally modify protein function in situ. The two main routes are modulation by light (optogenetics) and site-specific bio-orthogonal modification (bioconjugation) via Click chemistry. In the present article, we discuss both approaches and their influence on protein function.
