Revealing the anti-corrosion mechanism of fluconazole by experimental and theoretical studies

Through techniques such as electrochemical impedance spectroscopy and open circuit potential, the protective behavior of fluconazole against the mild steel corrosion process in neutral medium was evaluated. Best-fitted adsorption isotherm was the Frumkin model respect to Langmuir, which implies a multilayer protective film formation with lateral attraction between the adsorbed inhibitor molecules on mild steel surface. To document the protective mechanism, DFT computations and QTAIM analysis were carried out. The results, showed that the stability of the protection film is attributed to the flu-flu and flu-water clusters formation which, are stabilized by O-H center dot center dot center dot N, O-H center dot center dot center dot O, C-H center dot center dot center dot N, C-H center dot center dot center dot O, C-H center dot center dot center dot F hydrogen bonds, as well as p-stacking. Altogether, the results reported here suggest that the fluconazole is adsorbed on the metal surface demonstrating that electrostatic interactions are the most relevant in the corrosion process.

Anti-corrosion performance of covalent layer-by-layer assembled films via click chemistry reaction on the copper surface

Constructing the films with remarkable anti-corrosion performance is the key issue to metal protection. A kind of covalent layer-by-layer (LbL) assembly films of triazole is fabricated on the copper surface in this work. The covalent LbL system provides a promising and efficient protection. The optimum assembly layers are three and the best protection efficiency is 96.9 %. Enhancement in corrosion resistance is due to the formation of the covalent triazole films via the click chemistry reaction catalysed by cuprous oxide. The mechanism of protection is discussed via the surface analysis and the molecular dynamics simulation.

Bacterial diversity and enzymatic activity in a soil recently treated with tebuconazole

Tebuconazole is one of the most commonly used active substances from the group of triazoles, that exhibits high efficacy in plant protection against fungal diseases. It’s too frequent use may, however, pose risk to soil ecosystems, leading to changes in their biological diversity. This study was aimed at evaluating the effect of tebuconazole on population numbers, diversity, and structure of bacterial communities, and on the enzymatic activity of soil. Tebuconazole was introduced into the soil (sandy loam with pH 7.0) in the following doses in mg kg(-1) DM (dry matter) of soil: 0.00 (C), 0.02 (O), and 10.0 (T). It caused changes in the population numbers of diversity of bacteria as well as in the biochemical activity of soil. It stimulated the proliferation of organotrophic bacteria and inhibited that of actinobacteria. The r-strategists were found to predominate among both the organotrophs and actinobacteria in the soil with tebuconazole addition. The amplicon sequencing of the 16S encoding gene (SSU rRNA) demonstrated tebuconazole to elicit changes in the structure of bacterial communities. In all soil samples, the prevailing taxon at the Phylum level turned out to be Proteobacteria, followed by Firmicutes and Actinobacteria, whereas the lowest counts were noted for Verrucomicrobia. The relative abundance of the bacteria at the Phylum level decreased in the soil under the influence of tebuconazole. The most sensitive to the effect of tebuconazole applied in a dose of 10.0 mg kg(-1) turned out to be Acidobacteria, whereas the most resistant were Verrucomicrobia. The predominating taxon at the class level was Alphaproteobacteria, followed by Bacilli. Tebuconazole ensured favorable conditions for the development of bacteria from Kaistobacter and Bacillus genera as their OTUs were the highest in the soil treated with tebuconazole at 10.0 mg kg(-1). In turn, Phenylobacterium and Rhodoplanes were sensitive to soil treatment with tebuconazole at doses of 0.02 mg kg(-1) and 10.0 mg kg(-1). Tebuconazole proved to be a strong inhibitor of urease and catalase activities, while in turn it enhanced activities of dehydrogenases, acid phosphatase, alkaline phosphatase, and arylsulfatase.

Design and synthesis of novel quinoline/chalcone/1,2,4-triazole hybrids as potent antiproliferative agent targeting EGFR and BRAF(V600E) kinases

New quinoline / chalcone hybrids containing 1,2,4-triazole moiety have been designed, synthesized and their structures elucidated and confirmed by various spectroscopic techniques. The designed compounds showed moderate to good activity on different NCI 60 cell lines in a single-dose assay with a growth inhibition rate ranging from 50% to 94%. Compounds 7b, 7d, 9b, and 9d were the most active compounds in most cancer cell lines with a growth inhibition percent between 77% and 94%. Newly synthesized hybrids were evaluated for their anti-proliferative activity against a panel of four human cancer cell lines. Compounds 7a, 7b, 9a, 9b, and 9d showed promising antiproliferative activities. These compounds were further tested for their inhibitory potency against EGFR and BRAF(V600E )kinases with erlotinib as a reference drug. The molecular docking study of compounds 7a, 7b, 9a, 9b, and 9d revealed nice fitting into the active site of EGFR and BRAF(V600E) kinases. Compounds 7b, 9b, and 9d displayed the highest binding affinities and similar binding pattern to those of erlotinib.

New Substituted 5-Benzylideno-2-Adamantylthiazol[3,2-b][1,2,4]Triazol-6(5H)ones as Possible Anti-Inflammatory Agents

Background: Inflammation is a complex response to noxious stimuli promoted by the release of chemical mediators from the damaged cells. Metabolic products of arachidonic acid, produced by the action of cyclooxygenase and lipoxygenase, play important roles in this process. Several non-steroidal anti-inflammatory drugs act as cyclooxygenase inhibitors. However, almost all of them have undesired side effects. Methods: Prediction of the anti-inflammatory action of the compounds was performed using PASS Program. The anti-inflammatory activity was evaluated by the carrageenan paw edema test. COX and LOX inhibitory actions were tested using ovine COX-1, human recombinant COX-2 and soybean LOX-1, respectively. Docking analysis was performed using Autodock. Results: All designed derivatives had good prediction results according to PASS and were synthesized and experimentally evaluated. The compounds exhibited in vivo anti-inflammatory action with eleven being equal or better than indomethacin. Although, some of them had no or low inhibitory effect on COX-1/2 or LOX, certain compounds exhibited COX-1 inhibition much higher than naproxen and COX-2 inhibition, well explained by Docking analysis. Conclusions: A number of compounds with good anti-inflammatory action were obtained. Although, some exhibited remarkable COX inhibitory action this activity did not follow the anti-inflammatory results, indicating the implication of other mechanisms.

Zinc-based triazole metal complexes for efficient iodine adsorption in water

Radioactive iodine is extremely harmful to the environment, and it is of great significance to develop materials that efficiently remove iodine. We prepared two triazole metal complexes with simple method, denoted as Zn(tr)(OAc) and Zn(ttr)(OAc), which were used to adsorb iodine from aqueous solution. The properties and adsorption mechanism of the two materials were studied by different techniques including XRD, SEM, N-2 porosimetry at 77 K, FTIR, TGA, elemental analysis (EDS), and X-ray photoelectron spectroscopy (XPS). The results showed that both materials had good water and thermal stability. Pseudo-second-order kinetic model was better at describing the iodine adsorption kinetics onto the adsorbents. It was proved that chemical adsorption dominated, iodine mainly enriched on the materials in the form of I-3(-1). Zn(ttr)(OAc) had a higher adsorption capacity than Zn(tr)(OAc) due to the electron-donating group -NH2. The maximum adsorption capacity of the two materials for iodine reached 714.501 mg center dot g(-1) and 846.108 mg center dot g(-1) at 25 degrees C.

In silico design of a new Zn-triazole based metal-organic framework for CO2 and H2O adsorption

In search for future good adsorbents for CO2 capture, a nitrogen-rich triazole-type Metal-Organic Framework (MOF) is proposed based on the rational design and theoretical molecular simulations. The structure of the proposed MOF, named Zinc Triazolate based Framework (ZTF), is obtained by replacing the amine-organic linker of MAF-66 by a triazole, and its structural parameters are deduced. We used grand-canonical Monte Carlo (GCMC) simulations based on generic classical force fields to correctly predict the adsorption isotherms of CO2 and H2O. For water adsorption in MAF-66 and ZTF, simulations revealed that the strong hydrogen bonding interactions of water with the N atoms of triazole rings of the frameworks are the main driving forces for the high adsorption uptake of water. We also show that the proposed ZTF porous material exhibits exceptional high CO2 uptake capacity at low pressure, better than MAF-66. Moreover, the nature of the interactions between CO2 and the MAF-66 and ZTF surface cavities was examined at the microscopic level. Computations show that the interactions occur at two different sites, consisting of Lewis acid-Lewis base interactions and hydrogen bonding, together with obvious electrostatic interactions. In addition, we investigated the influence of the presence of H2O molecules on the CO2 adsorption on the ZTF MOF. GCMC simulations reveal that the addition of H2O molecules leads to an enhancement of the CO2 adsorption at very low pressures but a reduction of this CO2 adsorption at higher pressures.

G-quadruplex-based aptamers targeting human thrombin: Discovery, chemical modifications and antithrombotic effects

First studies on thrombin-inhibiting DNA aptamers were reported in 1992, and since then a large number of anticoagulant aptamers has been discovered. TBA – also named HD1, a 15-mer G-quadruplex (G4)-forming oligonucleotide – is the best characterized thrombin binding aptamer, able to specifically recognize the protein exosite I, thus inhibiting the conversion of soluble fibrinogen into insoluble fibrin strands. Unmodified nucleic acid-based aptamers, in general, and TBA in particular, exhibit limited pharmacokinetic properties and are rapidly degraded in vivo by nucleases. In order to improve the biological performance of aptamers, a widely investigated strategy is the introduction of chemical modifications in their backbone at the level of the nucleobases, sugar moieties or phosphodiester linkages. Besides TBA, also other thrombin binding aptamers, able to adopt a well-defined G4 structure, e.g. mixed duplex/quadruplex sequences, as well as homoand hetero-bivalent constructs, have been identified and optimized. Considering the growing need of new efficient anticoagulant agents associated with the strong therapeutic potential of these thrombin inhibitors, the research on thrombin binding aptamers is still a very hot and intriguing field. Herein, we comprehensively described the state-of-the-art knowledge on the DNA-based aptamers targeting thrombin, especially focusing on the optimized analogues obtained by chemically modifying the oligonucleotide backbone, and their biological performances in therapeutic applications.
