Rh-Catalyzed Formal [3+2] Cyclization for the Synthesis of 5-Aryl-2-(quinolin-2-yl)oxazoles and Its Applications in Metal Ions Probes

Main observation and conclusion A facile and efficient strategy for the synthesis of 5-aryl-2-(quinolin-2-yl)oxazoles via rhodium-catalyzed formal [3+2] cyclization of 4-aryl-1-tosyl-1H-1,2,3-triazoles with quinoline-2-carbaldehydes has been described. The protocol employs mild conditions and offers good yields of diverse 2,5-aryloxazole derivatives with a broad reaction scope. It is amenable to gram-scale synthesis and easily transformation. Moreover, this 5-aryl-2-(quinolin-2-yl)oxazole skeleton is indeed a new fluorophore and its applications in metal ions probes are also investigated and showed fluorescent responses to mercury ion.

Dual-supramolecular contacts induce extreme Hofmann framework distortion and multi-stepped spin-crossover

An extended nitro-functionalised 1,2,4-triazole ligand has been used to induce considerable lattice distortion in a 2-D Hofmann framework material via competing supramolecular interactions. Single crystal X-ray diffraction analyses on [Fe-3(N-cintrz)(6)(Pd(CN)(4))(3)]center dot 6H(2)O (N-cintrz: (E)-3-(2-nitrophenyl)acrylaldehyde) reveal a substantial deviation from a regular Hofmann structure, in particular as the intra- and inter-layer contacts are dominated by hydrogen-bonding interactions rather than the typical pi-stacking arrays. Also, the 2-D Hofmann layers show an assortment of ligand conformations and local Fe-II coordination environments driven by the optimisation of competing supramolecular contacts. Temperature-dependent magnetic susceptibility measurements reveal a two-step spin crossover (SCO) transition. Variable temperature structural analyses show that the two crystallographically distinct Fe-II centres, which are arranged in stripes (2 : 1 ratio) within each Hofmann layer, undergo a cooperative HS <-> HS/LS <-> LS (HS = high spin, LS = low spin) transition without periodic spin-state ordering. The mismatch between crystallographic (2 : 1) and spin-state (1 : 1) periodicity at the HS : LS step provides key insight into the competition (frustration) between elastic interactions and crystallographically driven order.

Copolymerization of o-phenylenediamine and 3-Amino-5-methylthio-1H-1,2,4-triazole for tuned optoelectronic properties and its antioxidant studies

The functionalization of conjugated polymers via copolymerization is one of the most pliable methods adopted to enhance their photophysical and optical properties. The current work accounts for the first-time copolymerization of o-phenylenediamine (OPD) with 3-Amino-5-methylthio-1H-1,2,4-triazole (AMTT) in a 1:1 molar ratio, using potassium dichromate (K2Cr2O7) as an oxidant and surfactant sodium dodecyl sulfate (SDS) as a soft template. Spectral, thermal, morphological, and optical studies through Fourier transform infrared spectroscopy, UV-Vis spectroscopy and TGA confirmed the copolymerization of poly(OPD-co-AMTT). The analysis of FTIR spectra showed the presence of benzenoid and quinonoid moiety in almost equal proportion. UV-Vis spectroscopy revealed high oscillator strength for the synthesized copolymer. The study of fluorescence spectra revealed that the quantum yield was dependent on the monomer composition in the copolymer. XRD and TEM studies revealed structural modifications in the morphology of the polymers on copolymerization while thermal studies suggested graft copolymerization. Antioxidant studies revealed significant antioxidant activity of tailored copolymer against DPPH free radical and hydrogen peroxide. (C) 2020 Elsevier B.V. All rights reserved.

Bicyclic 1,3a,6a-Triazapentalene Chromophores: Synthesis, Spectroscopy and Their Use as Fluorescent Sensors and Probes

The 1,3a,6a-triazapentalene (TAP) is an aromatic heterocyclic fluorescent dye with interesting features such as its small size, large Stokes shift, solvatochromism, and emission wavelengths that are spread across the visible spectrum. TAPs have been synthesized via different synthetic strategies involving click-cyclization-aromatization domino reactions, gold-catalyzed cyclization of propargyl triazoles or triazolization of acetophenones. As a result, TAPs with diverse substitution patterns were obtained, showing varying fluorescence properties. Based on these properties, several TAPs have been selected and studied as fluorescent imaging probes in living cells and as sensors. This mini review provides an overview of the research on the bicyclic TAPs and does not comment on the literature about benzo or otherwise fused systems. The synthetic methodologies for the preparation of TAPs, the substituent effects on the fluorescence properties, and the behavior of the TAP core as an element of biological imaging probes and sensors are discussed.

Synthesis of (Z)-3-((5-(benzylthio)-4H-1,2,4-triazol-3-yl)imino)-5-haloindolin-2-one derivatives: combined spectroscopic and computational investigations on the level and activity of matrix metalloproteinases 2 and 9 in cancer cell lines

Angiogenesis is an essential factor for cancer progression. Although more attention is paid in angiogenesis on its role in cancer biology, many other non-neoplastic diseases are also angiogenic-dependent. Recently, there is motivation to control cancer via inhibition of angiogenesis. Isatin-based scaffolds have been extensively used as anticancer agents in the recent years. Although some biological properties of isatin-based scaffolds are determined, their effects on angiogenesis are rare. So, we investigated the antiangiogenic effects of isatin-1,2,4-triazole conjugates. (Z)-3-((5-(benzylthio)-4H-1,2,4-triazol-3-yl)imino)-5-haloindolin-2-one macromolecules 1a-1l were synthesized and characterized, and the buffered solutions were used for evaluation of their cytotoxicity (cell viability) by MTT assay in vitro against U87MG (human glioblastoma astrocytoma) and A2780 (human ovarian carcinoma) cancer cell lines. Also, the effects of the compounds 1a-1l on supernatants activities and levels of matrix metalloproteinases (MMP-2 and MMP-9) were assayed using enzyme-linked immunosorbent assay (ELISA) and gelatin zymography. The compounds 1j-1l have the greatest cytotoxicity against studied cell lines. Moreover, our observations indicated that 1j-1l decreased the supernatants activity of MMP-2 and MMP-9 more than the others and all of the tested compounds considerably decreased the supernatant levels of MMP-9. The molecular mechanism of 1j binding to MMP-2 and MMP-9 was investigated by fluorescence quenching, absorption spectroscopy, FT-IR, molecular docking and molecular dynamics (MD) simulation procedures.

Aminotriazole isomers modified cellulose microspheres for selective adsorption of U(VI): Performance and mechanism investigation

Aminotriazole isomers with high nitrogen content show potential affinity for U(VI). Combining the advantages of both aminotriazole and cellulose, two n-aminotriazole isomers modified cellulose microspheres (n-ATARs, n = 3, 4) were newly prepared as adsorbents via radiation technology. Batch adsorption experiments showed that n-ATARs possessed good adsorption capacity of U(VI) in the order of 3-ATAR > 4-ATAR, and the adsorption process followed the Langmuir-Freundlich isotherm model and the pseudo-second-order kinetic model. Both n-ATARs exhibited good selectivity and reusability. Besides, 3-ATAR and 4-ATAR were more suitable for the extraction of trace amount of U(VI) from the contaminated groundwater and the simulated seawater, respectively. The effect of amino position on triazole ring on adsorption behavior of n-ATAR was studied and explained by DFT calculation. Finally, the adsorption mechanism of U(VI) onto n-ATARs was revealed to be inner-sphere complexation via different 1:1 or 1:2 coordination models by FTIR, MS, XPS analysis and DFT calculation.

Convenient ultrasonic preparation of a water stable cluster-based Cadmium(II) coordination material and highly sensitive fluorescent sensing for biomarkers DPA and 5-HT

In recent years, a new type of micro-porous material, namely metal organic framework material, has received more and more attention from many basic and industrial fields because these materials possess unique advantages. In this work, through the powerful sonochemical preparation method, a three-dimensional cluster based CdII-MOFs, {[Cd(abtz)(2)(H2O)(2)]center dot(ClO4)(2)center dot H2O}(n) (1, abtz = 1-(4-aminobenzyl)-1H-1,2,4-triazole) can be quickly synthesized in the facile ultrasonic method. Powder X-ray diffraction (PXRD) measurement confirms that these bulky samples 1 (synthesized on different ultrasonic powers and ultrasonic time conditions) were pure. In addition, ultrasonic chemical time and irradiation power did not change the structure of composites materials 1. SEM and morphological changes of 1 in the ultrasonic synthesis are also determined. Moreover, 1 exhibits good stability, the structure of 1 can be maintained not just in various solvents, and in aqueous environments with pH values from 2 to 12. Photo-luminescent experiment also reveals that complex 1 has the excellent application prospect as highly sensitive sensing material for the biomarker DPA (2,6-pyridine dicarboxylic acid) and 5-HT (5-hydroxytryptamine) through the photo-luminescence turn-on and turn-off effect, respectively. Further photo-luminescent measurements also show that different ultrasonic powers and ultrasonic time can effectively induce fluorescent sensing enhancement for biomarkers DPA and 5-HT based on the water stable clustered-based cadmium(II) coordination framework.
