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.

Probing phenylcarbamoylazinane-1,2,4-triazole amides derivatives as lipoxygenase inhibitors along with cytotoxic, ADME and molecular docking studies

Hunting small molecules as anti-inflammatory agents/drugs is an expanding and successful approach to treat several inflammatory diseases such as cancer, asthma, arthritis, and psoriasis. Besides other methods, inflammatory diseases can be treated by lipoxygenase inhibitors, which have a profound influence on the development and progression of inflammation. In the present study, a series of new N-alkyl/aralky/aryl derivatives (7a-o) of 2-(4-phenyl-5-(1-phenylcarbamoyl)piperidine-4H-1,2,4-triazol-3-ylthio)acetamide was synthesized and screened for their inhibitory potential against the enzyme 15-lipoxygenase. The simple precursor ethyl piperidine-4-carboxylate (a) was successively converted into phenylcarbamoyl derivative (1), hydrazide (2), semicarbazide (3) and N-phenylated 5-(1-phenylcarbamoyl)piperidine-1,2,4-triazole (4), then in combination with electrophiles (6a-o) through further multistep synthesis, final products (7a-o) were generated. All the synthesized compounds were characterized by FTIR, H-1, C-13 NMR spectroscopy, EIMS, and HREIMS spectrometry. Almost all the synthesized compounds showed excellent inhibitory potential against the tested enzyme. Compounds 7c, 7f, 7d, and 7g displayed potent inhibitory potential (IC50 9.25 +/- 0.26 to 21.82 +/- 0.35 mu M), followed by the compounds 7n, 7h, 7e, 7a, 7b, 7l, and 7o with IC50 values in the range of 24.56 +/- 0.45 to 46.91 +/- 0.57 mu M. Compounds 7c, 7f, 7d exhibited 71.5 to 83.5% cellular viability by MTT assay compared with standard curcumin (76.9%) when assayed at 0.125 mM concentration. In silico ADME studies supported the drug-likeness of most of the molecules. In vitro inhibition studies were substantiated by molecular docking wherein the phenyl group attached to the triazole ring was making a pi-delta interaction with Leu607. This work reveals the possibility of a synthetic approach of compounds in relation to lipoxygenase inhibition as potential lead compounds in drug discovery.

Spectroscopic and TDDFT studies of N-phenyl-N’-(3-triazolyl)thiourea) compounds with transition metal ions

Reaction of N-phenyl-N’-(3-triazolyl)thiourea) (H3L) with M(ClO4)(2) (M = Co(II) (1), Ni(II) (2) and Cu(II) (3)) afforded [M(H2L)(2)] complexes, which were characterized experimentally and theoretically using different analytical, and spectral tools. The susceptibility of Staphylococcus aureus and Escherichia coli bacteria towards H3L and its complexes was evaluated. The thiourea ligand coordinates to the 3d-metal ions via C-S-, and triazole nitrogen yielding coordination compounds between the tetrahedral, and square-planar geometries (flattened tetrahedron, D(2)d symmetry). Full geometry optimization, vibrational analyses, and natural bond orbital analyses of the proposed conformations of 1-3 were executed at B3LYP/def2-SVP to gain some knowledge about the local minima structures, natural charge of the coordinated metal ion, electronic configuration as well as the hybridization of M-L bonds. The electronic structures of the local minimum structures of 1-3 were investigated by time-dependent density functional theory calculations. Coordination of the thiourea ligand to Co(II) and Cu(II) ions did alter the toxicity against the tested microbes, while chelation of Ni(II) ion gave rise to inactive species.

Synthesis and size-dependent spin crossover of coordination polymer [Fe(Htrz)(2)(trz)](BF4)

The synthesis of quality single crystals is central to materials chemistry for optical, magnetic, and electronic device applications. The present work reports on the synthesis of single crystals of iron-triazole coordination polymer [Fe(Htrz)(2)(trz)](BF4) where (Htrz) = 1H-1,2,4-triazole. Crystals of size as long as 80 mu m can be achived by controlling the temperature, precursor concentration, and solvent type. It is found that its thermal spin crossover depends largely on the crystal size. Fine crystals are ideal for depositing a thin film that exhibits redox activity. The largest crystals allow reliable electrical conductance measurements that reveal two different activation energies at the low spin state and the high spin state, which are one order of magnitude smaller than the electronic gaps calculated based on density functional theory. The synthetic route sought in the present study can be applied to other coordination polymers and related materials and provides the basis for their applications.
