A stable terbium(III) metal-organic framework as a dual luminescent sensor for MnO4- ions and nitroaromatic explosives

A new terbium(III) metal-organic framework [Tb-2(BTZ)(mu(2)-H2O)(mu(3)-OH)(2)] (ZH-101, H(2)BTZ = 3.5-bis(4′-carboxy-phenyl)-1,2,4-triazole) was synthesized with BTZ ligands under solvothermal conditions for the luminescent study. It is constructed of [Tb-2(mu(2)-O)(mu(3)-O)2](n) 2D layered structure and is further connected by BTZ ligands with rich triazole-N sites to form a water-gable 3D net framework. ZH-101 displays excellent chemical stability in common organic solvents and water in the wide pH range of 0-11. The luminescence test experiment of ZH-101 in water containing different anions shows selective fluorescence quenching for MnO4- with low detection limit (0.16 mM). In addition, ZH-101 also displays excellent luminescence stability in different solvents and can selectively detect nitroaromatic explosives in DMF solutions, especially for 4-nitrophenol with K-sv = 3.38 x 10(4) M-1, and low detection limit of 0.20 mM. It still retains original fluorescence intensity and chemical stability after five cycles experiments, exhibiting remarkable long-term cycle and reversibility. Therefore, ZH-101 is a competitive and promising candidate for sensing MnO4- ions and nitroaromatic explosives.

The Catalytic Activity of Carbon-Supported Cu(I)-Phosphine Complexes for the Microwave-Assisted Synthesis of 1,2,3-Triazoles

A set of Cu(I) complexes with 3,7-diacetyl-1,3,7-triaza-5-phosphabicyclo-[3.3.1]nonane (DAPTA) phosphine ligands viz. [CuX(kappa P-DAPTA)(3)] (1: X = Br; 2: X = I) and [Cu(mu-X)(kappa P-DAPTA)(2)](2) (3: X = Br; 4: X = I) were immobilized on activated carbon (AC) and multi-walled carbon nanotubes (CNT), as well as on these materials after surface functionalization. The immobilized copper(I) complexes have shown favorable catalytic activity for the one-pot, microwave-assisted synthesis of 1,2,3-triazoles via the azide-alkyne cycloaddition reaction (CuAAC). The heterogenized systems with a copper loading of only 1.5-1.6% (w/w relative to carbon), established quantitative conversions after 15 min, at 80 degrees C, using 0.5 mol% of catalyst loading (relative to benzyl bromide). The most efficient supports concerning heterogenization were CNT treated with nitric acid and NaOH, and involving complexes 2 and 4 (in the same order, 2 CNT-ox-Na and 4_CNT-ox-Na). The immobilized catalysts can be recovered and recycled by simple workup and reused up to four consecutive cycles although with loss of activity.

Spectroscopic and electrochemical recognition of H2PO4- based on a ruthenium complex with 2-picolinamide

A ruthenium polypyridyl complex 4(PF6) with 2-picolinamide as an anionic N <^> N bidentate ligand is synthesized and characterized, including single-crystal X-ray analysis. As an effective anion receptor in CH2Cl2, complex 4(PF6) shows selective spectroscopic and electrochemical recognition towards H2PO4- over other anions tested (F-, Cl-, Br-, I-, HP2O73-, HSO4-, AcO- and NO3-). Job’s plot and mass spectral analyses support that an adduct is formed between 4 and H2PO4- with a 1:2 binding stoichiometry. The absorption spectral titration of 4(PF6) with H2PO4- yields a global association constant in the order of 10 8 L-2.mol(-2) and an optical detection limit of 1.4 x 10(-6) mol.L-1. In response to the presence of H2PO4-, the Ru(II/III) redox couple of 4(PF6) displays a two-wave behavior accompanied by a large negative shift from + 0.74 to + 0.45 V vs Ag/AgCl. H-1 NMR spectral titration analyses suggest that effective hydrogen bonding interactions are present between 4 and H2PO4-, which are believed responsible for the observed spectroscopic and electrochemical response of 4(PF6) toward H2PO4-.

Antibacterial Activity of Fluorobenzoylthiosemicarbazides and Their Cyclic Analogues with 1,2,4-Triazole Scaffold

The development of drug-resistant bacteria is currently one of the major challenges in medicine. Therefore, the discovery of novel lead structures for the design of antibacterial drugs is urgently needed. In this structure-activity relationship study, a library of ortho-, meta-, and para-fluorobenzoylthiosemicarbazides, and their cyclic analogues with 1,2,4-triazole scaffold, was created and tested for antibacterial activity against Gram-positive bacteria strains. While all tested 1,2,4-triazoles were devoid of potent activity, the antibacterial response of the thiosemicarbazides was highly dependent on substitution pattern at the N4 aryl position. The optimum activity for these compounds was found for trifluoromethyl derivatives such as 15a, 15b, and 16b, which were active against both the reference strains panel, and pathogenic methicillin-sensitive and methicillin-resistant Staphylococcus aureus clinical isolates at minimal inhibitory concentrations (MICs) ranging from 7.82 to 31.25 mu g/mL. Based on the binding affinities obtained from docking, the conclusion can be reached that fluorobenzoylthiosemicarbazides can be considered as potential allosteric d-alanyl-d-alanine ligase inhibitors.

Construction of an IMiD-based azide library as a kit for PROTAC research

As a promising protein degradation strategy, PROTAC technology is increasingly becoming a new star in cancer treatment. Here we report the efficient construction of an IMiD-based azide library via a quick one-step conversion of the existing IMiD-based amine library. This new azide library can act as a kit to endow PROTAC libraries with triazole moieties for various POIs through a highly effective ‘click reaction’ and then help to rapidly screen out lead degraders that are valuable for drug development. Its power in fleetly identifying potent degraders has been verified on two oncogenic proteins, BCR-ABL and BET, the degraders of which showed comparable potency to or even higher potency than the reported PROTACs in degrading target proteins and effectively inhibiting cancer cell proliferation.

Application of 464-48-2, Because enzymes can increase reaction rates by enormous factors and tend to be very specific, typically producing only a single product in quantitative yield, they are the focus of active research.you can also check out more blogs about 464-48-2.

Cu(I)-N-heterocyclic carbene-catalyzed base free C-N bond formation of arylboronic acids with amines and azoles

A new N-heterocyclic carbene (NHC) precursor of imidazolium chloride and its corresponding Cu(I)-NHC complex 1 was synthesized. The complex 1 was found to be a highly effective catalyst for Chan-Evans-Lam coupling of arylboronic acid with amines and azoles (including imidazole, pyrazole and triazole), without addition of base at room temperature. Various substituents on three substrates can be tolerated, giving the desired coupling products in good to excellent yields (62-94%). The method is practical and offers an alternative to the corresponding copper-catalyzed Chan-Evans-Lam process for the construction of C-N bonds. (C) 2020 Published by Elsevier Ltd.

Evaluation of some new heterocycles bearing 2-oxoquinolyl moiety as immunomodulator against highly pathogenic avian influenza virus (H5N8)

The hydrazide obtained from furan-2(3H)-one integrated with a quinolin-2(1H)-one core reported previously by our research group was utilized as a building block synthon to obtain some pyrrolone, pyridazinone, oxadiazole, and triazole derivatives through treating with some carbon electrophilic reagents, for example, chloroacetyl chloride, benzoyl chloride, acetic anhydride, carbon disulfide, 3,4-dimethoxybenzaldehyde, and 2-oxoquinolin-3-carbaldehyde to achieve the target heterocycles. The newly synthesized compounds were evaluated as immunomodulator against highly pathogenic avian influenza virus (H5N8). The compounds 1, 11, and 17 displayed the highest potency (100% protection).

Effects of Network Structures on the Tensile Toughness of Copper-Catalyzed Azide-Alkyne Cycloaddition (CuAAC)-Based Photopolymers

In the present study, photoinitiated copper-catalyzed azide-alkyne cycloaddition (CuAAC) polymerization was utilized to form structurally diverse glassy polymer networks. Systematic alterations in the monomer backbone rigidity (e.g., cyclic or aliphatic groups with a different length of the backbone) and the reactive functional group density (e.g., tetra-, tri-, di-, and monofunctional azide and alkyne monomers) were used to provide readily tailorable network structures with cross-link densities (estimated from the rubbery modulus) varying by a factor of over 20. All eight of the resultant networks exhibited glass transition temperatures (T-g(s)) between 50 and 80 degrees C with the tensile toughness ranging from 28 to 61 MJ m(-3). A nearly linear dependence of yield stress and elongation at break (broadly defined as strength and ductility, respectively) on the T-g and rubbery modulus was established in these triazole networks. When a flexible dialkyne monomer (five carbon spacing between alkynes) was incorporated into a network composed of a tri-alkyne and di-azide monomer, the elongation at break was improved from 166 to 300%, while the yield stress was reduced from 36 to 23 MPa. Additionally, the polymer ductility was also varied by incorporating monofunctional azides as chain ends into the network-replacing a sterically hindered stiff mono-azide with a more flexible mono-azide increased the elongation at break from 24 to 185% and the tensile toughness from 6 to 28 MJ m(-3).

Antifungal Activity of Melaleuca alternifolia Essential Oil (TTO) and Its Synergy with Itraconazole or Ketoconazole against Trichophyton rubrum

Over the past 20-30 years, Trichophyton rubrum represented the most widespread dermatophyte with a prevalence accounting for 70% of dermatophytosis. The treatment for cutaneous infections caused by Trichophyton spp. are imidazoles (ketoconazole (KTZ)) and triazoles (itraconazole (ITZ)). T. rubrum can develop resistance to azoles after prolonged exposure to subinhibitory concentrations resulting in therapeutic failures and chronic infections. These problems have stimulated the search for therapeutic alternatives, including essential oils, and their potential use in combination with conventional antifungals. The purpose of this study was to evaluate the antifungal activity of tea tree oil (TTO) (Melaleuca alternifolia essential oil) and the main components against T. rubrum and to assess whether TTO in association with KTZ/ITZ as reference drugs improves the antifungal activity of these drugs. We used a terpinen-4-ol chemotype (35.88%) TTO, and its antifungal properties were evaluated by minimum inhibitory and minimum fungicidal concentrations in accordance with the CLSI guidelines. The interaction between TTO and azoles was evaluated through the checkerboard and isobologram methods. The results demonstrated both the fungicide activity of TTO on T. rubrum and the synergism when it was used in combination with azoles. Therefore, this mixture may reduce the minimum effective dose of azole required and minimize the side effects of the therapy. Synergy activity offered a promise for combination topical treatment for superficial mycoses.

Evaluation of bi-functionalized alumina-epoxy nanocomposite coatings for improved barrier and mechanical properties

The effect of embedding bi-functionalised alumina nanoparticle in epoxy resin and its electrochemical and mechanical properties has been extensively investigated. An amino (-NH2) and thio (-SH) functionalized nano alumina particles were synthesized and characterized by Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), Thermogravimetric analysis (TGA), and SEM/EDX technique. The colloidal behaviour of alumina-epoxy nanocomposite was influenced effectively by the presence of 3-amino-1, 2, 4-triazole-5-thiol (3ATT) as bi-functional group. The physical, thermal, mechanical and electrical properties of the nanocomposite exhibited strong dependence on the nature of functionalization. The pure epoxy resin and bifunctionalized alumina-epoxy nanocomposite were coated on the mild steel and their protective properties against corrosion were analysed by electrochemical techniques. The current measured at the scratch by scanning electrochemical microscopy (SECM) was much lower (2.5 nA) for the bi-functionalized alumina-epoxy nanocomposite coated steel than pure epoxy coated steel (10.0 nA) at 40 d immersion in seawater. Enhancement of the coating resistance was observed by electrochemical impedance spectroscopy (EIS) for the bi-functionalized alumina-epoxy nanocomposite coated steel (R-c = 2598.35 k Omega.cm(2)) compared with pure epoxy coated steel (R-c = 9.45 k Omega.cm(2)) at 40 d immersion in seawater. Addition of 3 wt% of bi-functionalized alumina nanoparticle in the epoxy matrix significantly improved its inhibitive and protective properties against corrosion. Surface morphological studies were done by FE-SEM/EDX technique. Mechanical properties have been greatly improved by the reinforcement of bi-functionalized alumina in the epoxy resin. It is reported for the first time that the barrier and mechanical properties of nanocomposite consisting of epoxy-bi-functionalized/alumina nanoparticles with -NH2 and thiol (-SH) are improved significantly. A possible mechanism has also been proposed for the investigated coatings.
