Facile synthesis, antimicrobial evaluation and molecular docking studies of pyrazole-imidazole-triazole hybrids

A series of eighteen pyrazole-imidazole-triazole hybrid (2-(4-((2-(substituted-1H-pyrazol-1-yl)-4-phenyl1H-imidazol-1-yl)methyl)-1H-1,2,3-triazol-1-yl)-N-(substituted)phenylacetami- de) (6a-6r) are synthesized through click reaction between in situ generated 2-azido-N-substituted acetamide and N-propargylated pyrazole-imidazole derivatives which in turn has been obtained regioselectively from 1(1-H-imidazol-2-yl)-1H-pyrazole and propargyl bromide. The structure of synthesized compounds (6a-6r) was confirmed by various spectroscopic studies (1D and 2D NMR, FT-IR, HRMS) and evaluated for antimicrobial activity. The compound 6m demonstrated excellent potency for A. niger (MIC value 0.0064 mu mol/mL); even better than that of the reference drug Fluconazole (MIC value 0.0112 mu mol/mL). Further, the binding conformation of most active compounds was ascertained by molecular docking studies. (C) 2020 Elsevier B.V. All rights reserved.

Synthesis of novel 1,2,3 triazole derivatives and assessment of their potential cholinesterases, glutathione S-transferase enzymes inhibitory properties: An in vitro and in silico study

In this study, new 1,2,3-triazole derivatives containing chalcone core (1-7) were synthesized. Obtained compounds were characterized by IR, H-1 NMR, C-13 NMR, and mass studies. Characterized compounds (1-7) inhibitory effects were tested against the glutathione S-transferase (GST), acetylcholinesterase (AChE), and Butyrylcholinesterase (BChE). Their K-i values were in the range of 5.88-11.13 mu M on AChE, 5.08-15.12 mu M on BChE, and 9.82-13.22 mu M on GST. Remarkable inhibitory effects were obtained against three tested metabolic enzymes. Also, binding scores of the best-inhibitors against AChE, BChE, and GST enzymes were detected as -9.969 kcal/mol, -10.672 kcal/mol, and -8.832 kcal/mol, respectively. Isoindoline-1,3-dione and benzothiophene moieties played a critical role in the inhibition of AChE and BChE enzymes, respectively. Phenylene and triazole moieties had the most important interactions for inhibition of the GST enzyme. Therefore, in vivo and in silico results indicated that these compounds can be considered in drug design processes for the treatment of some diseases including Alzheimer’s disease (AD), leukemia, and some type of cancer.

The impact of fungal allergic sensitization on asthma

Purpose of review Fungal sensitization may contribute to the development of asthma as well as asthma severity. The purpose of this review is to summarize existing knowledge about the pathophysiology, diagnosis, and management of fungal sensitization in asthma and highlight unmet needs and target areas for future investigation. Recent findings Fungal sensitization may occur by a normal or aberrant immune response. Allergic sensitization to fungi is mediated by the adaptive immune response driven by T(H)2 cells and the innate immune response driven by the innate lymphoid cells group 2. Diagnosis of fungal sensitization can be made by either skin prick testing or measurement of fungal-specific serum IgE. Fungal sensitization in asthma has been associated with worse disease severity, including reduced lung function, increased risk of hospitalizations, and life-threatening asthma. A spectrum of disease related to fungal sensitization has been described in asthma including allergic bronchopulmonary mycosis and severe asthma with fungal sensitization (SAFS). The role of antifungals and targeted biologic therapy in asthma with fungal sensitization need further investigation. There is increasing awareness of the contribution of fungal sensitization to asthma severity. However, there are no therapies with proven efficacy. Randomized clinical trials are needed to further investigate the role of biologics.

Novel silver(I) cluster-based coordination polymers as efficient luminescent thermometers

By employing a triazole-pyridine-containing ligand, two novel coordination polymers with Ag(I) clusters exhibiting different architectures have been successfully constructed. Structural analysis indicates that diverse coordination modes of the N-donor linker are responsible for the network difference for these two compounds, affording an isolated cluster for 1 and a 2D framework for 2, respectively. Compound 1 features a butterfly-shaped [Ag-8(bptp)(4)(H2O)(2)] cluster wherein strong argentophilic interactions could be observed. The linkage of Ag(I) with N and I centers gives rise to a tetranuclear building unit [Ag-4(bptp)(3)I] in 2, which is further extended to a 2D network with the assistance of the N-donor linkers. The syntheses and crystal structures have been investigated. Solid-state photoluminescence emissions as well as luminescence lifetimes of 1 and 2 have also been studied. Moreover, temperature-dependent luminescence tests show that an excellent linear relationship between temperature and emission intensity in the ranges of 77-298 K and 77-200 K could be observed for compounds 1 and 2, respectively. The wide temperature sensing range especially for 1 implies that they could act as promising ratiometric fluorescence molecular thermometers.

Investigation of the Reactivity of 1-Azido-3-iodobicyclo[1.1.1]pentane under Click Reaction Conditions

The bicyclo[1.1.1]pentane (BCP) unit is under scrutiny as a bioisostere in drug molecules. We employed methodologies for the synthesis of different BCP triazole building blocks from one precursor, 1-azido-3-iodobicyclo[1.1.1]pentane, by click reactions and integrated cycloaddition-Sonogashira coupling reactions. Thereby, we accessed 1,4-disubstituted triazoles, 5-iodo-1,4,5-trisubstituted triazoles, and 5-alkynylated 1,4,5-trisubstituted triazoles. This gives entry to the synthesis of multiply substituted BCP triazoles on either a modular or a one-pot basis. These methodologies were further utilized for appending porphyrin moieties onto the BCP core.

Ester modification at the 3 ‘ end of anti-microRNA oligonucleotides increases potency of microRNA inhibition

MicroRNAs (miRNAs) are short noncoding RNAs that play a fundamental role in gene regulation. Deregulation of miRNA expression has a strong correlation with disease and antisense oligonucleotides that bind and inhibit miRNAs associated with disease have therapeutic potential. Current research on the chemical modification of anti-miRNA oligonucleotides (anti-miRs) is focused on alterations of the phosphodiester-ribose backbone to improve nuclease resistance and binding affinity to miRNA strands. Here we describe a structure-guided approach for modification of the 3′-end of anti-miRs by screening for modifications compatible with a nucleotide-binding pocket present on human Argonaute-2 (hAgo2). We computationally screened a library of 190 triazole-modified nucleoside analogs for complementarity to the t1A-binding pocket of hAgo2. Seventeen top scoring triazoles were then incorporated into the 3′ end of anti-miR21 and potency was evaluated for each in a cell-based assay for anti-miR activity. Four triazole-modified anti-miRs showed higher potency than anti-miR21 bearing a 3′ adenosine. In particular, a triazole-modified nucleoside bearing an ester substituent imparted a ninefold and five-fold increase in activity for both anti-miR21 and anti-miR122 at 300 and 5 nM, respectively. The ester group was shown to be critical as a similar carboxylic acid and amide were inactive. Furthermore, anti-miR 3′ end modification with triazole-modified nucleoside analogs improved resistance to snake venom phosphodiesterase, a 3’-exonuclease. Thus, the modifications described here are good candidates for improvement of anti-miR activity.

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.

Synthesis, characterization, in vitro biological and computational evaluation of 5-benzyl-4-(benzylideneamino)-2H-1,2,4-triazole-3(4H)-thiones

Triazoles and their heterocyclic analogues are nitrogen-rich versatile pharmacophores easily synthesized and converted to a range of biologically relevant heterocycles. In this context, the present research reports the synthesis, characterization, in vitro antioxidant, cytotoxic and alpha-glucosidase inhibitory potential of 4-amino-5-benzyl-2H-1,2,4-triazol-3(4H)-thione (3) and 5-benzyl-4-(benzylideneamino)-2H-1,2,4-triazole-3(4H)-thiones 5(a-g). Consequently, the percent DPPH free radical scavenging ability was found to be in the decreasing order of 5 g > 5e > 3 > 5d > 5b > 5c > 5a > 5f. The most potent derivatives (5 g), (5e) and (3) showed significant dose-dependent scavenging ability with IC50 values of 61.22, 74.06 and 94.87 mu g/ml, respectively. The antioxidant derivatives were screened in brine shrimp lethality as well as protein kinase inhibitory assay to unveil their toxic nature. The percent mortality was found to be decreasing in the order of 5b > 5f > 3 > 5a > 5 g > 5d > 5e > 5c at 200 mu g/ml in brine shrimp lethality assay. Accordingly, three derivatives (5b), (3) and (5f) showed significant percent mortality with LC50 values of 25.88, 32.94 and 34.87 mu g/ml, respectively. Similarly, in protein kinase inhibitory assay, maximum inhibitory potential was observed for the derivatives (5 g), (3) and (5e) with MIC values of 50 mu g/disc in each case. Likewise, in alpha-glucosidase inhibition assay, the screened derivatives (3) and (5e) showed notable percent alpha-glucosidase inhibition (66.78 and 55.15%) with IC50 value of 36.11 mu g/ml and 60.33 mu g/ml, respectively. Molecular docking studies of the screened derivatives were performed in order to assess their binding potential and mechanism of their binding with alpha-glucosidase, alpha-kinase and beta-kinase enzymes. Docking simulation revealed that the molecules stabilize themselves inside the active site by establishing non-covalent interactions with critical residues. Noteworthy were the derivatives (3) and (5e) which anchored themselves through various significant electrostatic interactions with the critical residues. [GRAPHICS] .

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.

New potent steroid sulphatase inhibitors based on 6-(1-phenyl-1H-1,2,3-triazol-4-yl)naphthalen-2-yl sulphamate derivatives

In the present work, we report a new class of potent steroid sulphatase (STS) inhibitors based on 6-(1-phenyl-1H-1,2,3-triazol-4-yl)naphthalen-2-yl sulphamate derivatives. Within the set of new STS inhibitors, 6-(1-(1,2,3-trifluorophenyl)-1H-1,2,3-triazol-4-yl)naphthalen-2-yl sulphamate 3L demonstrated the highest activity in the enzymatic assay inhibiting the STS activity to 7.98% at 0.5 mu M concentration. Furthermore, to verify whether the obtained STS inhibitors are able to pass through the cellular membrane effectively, cell line experiments have been carried out. We found that the lowest STS activities were measured in the presence of compound 3L (remaining STS activity of 5.22%, 27.48% and 99.0% at 100, 10 and 1 nM concentrations, respectively). The measured STS activities for Irosustat (used as a reference) were 5.72%, 12.93% and 16.83% in the same concentration range. Moreover, a determined IC50 value of 15.97 nM for 3L showed that this compound is a very promising candidate for further preclinical investigations.
