Structural characterization and QSAR modeling of 1,2,4-triazole derivatives as alpha-glucosidase inhibitors

In order to identify potential new drugs that could be useful in preventing and treating diabetes, we benchmarked several exchange-correlation functionals and ab initio methods to accurately describe the structural, electronic and vibrational properties of 1,2,4-triazole (Tz) and 1,2,4-triazolone (TzO). This theoretical approach was employed to develop a QSAR model to correlate the quantum chemical descriptors of 1,2,4-triazolone derivatives with their antidiabetic activity. The best statistically significant correlations between the biological activity and the descriptors were generated after a multiple linear regression (MLR) analysis. A QSAR model was successfully developed and a good correlation between the experimental and predicted activity values was described.

Synthesis, antimicrobial activities, docking studies and computational calculations of new bis-1,4-phenylene-1H-1,2,3-triazole derivatives utilized ultrasonic energy

In this elucidation, we studied the utility of condensation reaction between 1,4-phenylenediamine (1) with acetyl acetone (2) with hydrazine hydrate utilized ultrasonic energy in one step reaction to afford the corresponding 1,1 ‘-(1,4-phenylenebis (5-methyl-1H-1,2,3-triazole-1,4-diyl))bis(ethan-1-one) (4) in excellent yield.

Fungal bronchitis is a distinct clinical entity which is responsive to antifungal therapy

Chronic productive cough in the context of exacerbations of airway disease can be associated with positive sputum cultures for fungi, in particular Aspergillus fumigatus and Candida spp., suggesting fungal bronchitis, a condition not widely recognised, as a possible cause for the exacerbation. Our objective was to determine the response to antifungal therapy in patients with suspected fungal bronchitis. Retrospective analysis of data extracted from case records of patients under secondary care respiratory clinics who had been treated with triazole therapy for suspected fungal bronchitis between 2010-2017. Primary outcome was lung function response after 1 month of treatment. Nineteen patients with fungal bronchitis due to A. fumigatus and 12 patients due to Candida spp., were included in the study. Most of the patients, particularly in the Aspergillus group, had allergic fungal airway disease on a background of asthma. All but one of the patients in each group were recorded as showing clinical improvement with antifungal therapy. In the majority of patients this was reflected in an improvement in lung function. Aspergillus group: FEV1 (1.44 +/- 0.8 L vs 1.6 +/- 0.8 L: p < 0.02), FVC (2.49 +/- 1.08 L vs 2.8 +/- 1.1 L: p = 0.01), and PEF (260 +/- 150L/min vs 297 +/- 194ml/min: p < 0.02). Candida group: FEV1 (1.6 +/- 0.76 L vs 2.0 +/- 0.72 L: p < 0.004), FVC (2.69 +/- 0.91 L vs 3.13 +/- 0.7 L: p = 0.05), and PEF (271 +/- 139L/min vs 333 +/- 156 L/min: p = 0.01). Side effects of treatment were common, but resolved on stopping treatment. This service improvement project supports the idea that fungal bronchitis is a distinct clinical entity which is responsive to treatment. Controlled clinical trials to confirm the clinical impression that this is relatively common and treatable complication of complex airway disease are required. But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 818-61-1, you can contact me at any time and look forward to more communication.

Design, Synthesis, Molecular Modeling, Anticancer Studies, and Density Functional Theory Calculations of 4-(1,2,4-Triazol-3-ylsulfanylmethyl)-1,2,3-triazole Derivatives

New conjugates of substituted 1,2,3-triazoles linked to 1,2,4-triazoles were synthesized starting from the appropriate S-propargylated 1,2,4-triazoles 7 and 8. Ligation of 1,2,4-triazoles to the 1,2,3-triazole core was performed through Cu(I)-catalyzed cycloaddition of 1,2,4-triazole-based alkyne side chain 7 and/or 8 with several un/functionalized alkyl- and/or aryl-substituted azides 9-15 to afford the desired 1,4-disubstituted 1,2,3-triazoles 16-27, using both classical and microwave methods. After their spectroscopic characterization (infrared, H-1, C-13 nuclear magnetic resonance, and elemental analyses), an anticancer screening was carried out against some cancer cell lines including human colon carcinoma (Caco-2 and HCT116), human cervical carcinoma (HeLa), and human breast adenocarcinoma (MCF-7). The outcomes of this exploration revealed that compounds 17, 22, and 25 had a significant anticancer activity against MCF-7 and Caco-2 cancer cell lines with IC50 values of 0.31 and 4.98 mu M, respectively, in relation to the standard reference drug, doxorubicin. Enzyme-docking examination was executed onto cyclin-dependent kinase 2; a promising aim for cancer medication. Synthesized compounds acquiring highest potency showcased superior interactions with the active site residue of the target protein and exhibited minimum binding energy. Finally, the density functional theory (DFT) calculations were carried out to confirm the outcomes of the molecular docking and the experimental findings. The chemical reactivity descriptors such as softness (delta), global hardness (eta), electronegativity (chi), and electrophilicity were calculated from the levels of the predicted frontier molecular orbitals and their energy gap. The DFT results and the molecular docking calculation results explained the activity of the most expectedly active compounds 17, 22, and 25.

Efficient photorelease of carbon monoxide from a luminescent tricarbonyl rhenium(I) complex incorporating pyridyl-1,2,4-triazole and phosphine ligands

Precise control over the production of carbon monoxide (CO) is essential to exploit the therapeutic potential of this molecule. The development of photoactive CO-releasing molecules (PhotoCORMs) is therefore a promising route for future clinical applications. Herein, a tricarbonyl-rhenium(I) complex (1-TPP), which incorporates a phosphine moiety as ancilliary ligand for boosting the photochemical reactivity, and a pyridyltriazole bidentate ligand with appended 2-phenylbenzoxazole moiety for the purpose of photoluminescence, was synthesized and characterized from a chemical and crystallographic point of view. Upon irradiation in the near-UV range, complex 1-TPP underwent fast photoreaction, which was monitored through changes of the UV-vis absorption and phosphorescence spectra. The photoproducts (i.e. the dicarbonyl solvento complex 2 and one CO molecule) were identified using FTIR, H-1 NMR and HRMS. The results were interpreted on the basis of DFT/TD-DFT calculations. The effective photochemical release of CO associated with clear optical variations (the emitted light passed from green to orange-red) could make 1-TPP the prototype of new photochemically-active agents, potentially useful for integration in photoCORM materials.

A series of novel triazole linked isatin-dihydropyridine hybrids (N1-N15) have been synthesized and examined for their anti proliferative activity against human cancer cell lines viz. HeLa, Huh-7, PC-3, IMR-32 and MCF-7. All of the synthesized hybrids have shown moderate to potent cytotoxicity against all the tested cell lines except IMR-32.

Separation of chalcopyrite from galena with 3-amyl-4-amino-1, 2, 4-triazole-5-thione collector: Flotation behavior and mechanism

3-Amyl-4-amino-1,2,4-triazole-5-thione (AATT) reacted with Cu2+ or Pb2+ ions in aqueous solutions to form CuAATT and Pb(AATT)(2) complexes and their solubility product constants were measured as 10(-16.17) and 10(-20.60), respectively. In the moderately-alkaline media, both chalcopyrite and galena chemisorbed AATT on to their surfaces, and the adsorption amount of AATT on chalcopyrite was bigger than that on galena, which rendered a stronger hydrophobization toward chalcopyrite. While under the high-alkaline pulp, AATT only chemisorbed on chalcopyrite, not on galena. The micro-flotation findings indicated that AATT was a favorable collector for flotation enrichment of chalcopyrite and galena at pH <11.0, and realized an efficient flotation separation of chalcopyrite from galena under pH>11.5. The CuAATTcomplex was more insoluble than Pb(AATT)2, which implied a stronger affinity of AATT toward chalcopyrite than galena and returned their selective flotation separation at the high-alkaline condition.
