Copper-catalyzed one-pot synthesis of amide linked 1,2,3-triazoles bearing aryloxy skeletons

In this paper, novel amide linked 1,2,3-triazoles containing aryloxy derivatives (8a-l) are synthesized via copper-catalyzed one-pot sequential hydroxylation-O-alkylation/click reaction of 2-bromo-N-prop-2-ynyl-benzamides. The products are synthesized in an efficient way in high isolated yields. The synthetic method involves the use of 2-bromo-N-prop-2-ynyl-benzamide and various benzyl halides over a onepot copper-catalyzed hydroxylation-O-alkylation/Click reaction. The products are characterized by H-1 NMR, C-13 NMR, mass spectrometry, FT-IR, elemental analysis, melting point, and single crystal X-ray diffraction. In-situ prepared phenol moiety in H2O/DMF as a solvent co-solvent system prompted to perform a reaction between benzyl halide and phenols. The step economic feature of the method leads to the synthesis of the products in high isolated yields. (C) 2020 Published by Elsevier Ltd.

Synthesis and biological evaluation of a new series of benzofuran-1,3,4-oxadiazole containing 1,2,3-triazole-acetamides as potential alpha-glucosidase inhibitors

A series of new benzofuran-1,3,4-oxadiazole containing 1,2,3-triazole-acetamides 12a-n as potential anti-alpha-glucosidase agents were designed and synthesized. alpha-Glucosidase inhibition assay demonstrated that all the synthesized compounds 12a-n (half-maximal inhibitory concentration [IC50] values in the range of 40.7 +/- 0.3-173.6 +/- 1.9 mu M) were more potent than standard inhibitor acarbose (IC50 = 750.0 +/- 12.5 mu M). Among them, the most potent compound was compound 12c, with inhibitory activity around 19-fold higher than acarbose. Since the most potent compound inhibited alpha-glucosidase in a competitive mode, a docking study of this compound was also performed into the active site of alpha-glucosidase. In vitro and in silico toxicity assays of the title compounds were also performed.

Effect of QTC-4-MeOBnE Treatment on Memory, Neurodegeneration, and Neurogenesis in a Streptozotocin-Induced Mouse Model of Alzheimer’s Disease

Growing evidence suggests that drugs targeting neurogenesis and myelinization could be novel therapeutic targets against Alzheimer’s disease (AD). Intracerebroventricular (icv) injection of streptozotocin (STZ) induces neurodegeneration through multiple mechanisms ultimately resulting in reduced adult neurogenesis. Previously, the multitarget compound QTC-4-MeOBnE (1-(7-chloroquinolin-4-yl)-N-(4-methoxybenzyl)-5-methyl-1H-1,2,3-triazole-4-carboxamide) demonstrated beneficial effects in preclinical models of AD. Here we investigated its pharmacokinetics profile and the effect on memory impairments and neurodegeneration induced by STZ. Two icv injections of STZ resulted in significant cognitive and memory impairments, assessed by novel object recognition, Y-maze, social recognition, and step-down passive avoidance paradigms. These deficits were reversed in STZ-injected mice treated with QTC-4-MeOBnE. This effect was associated with reversion of neuronal loss in hippocampal dentate gyrus, reduced oxidative stress, and amelioration of synaptic function trough Na+/K+ ATPase and acetylcholinesterase activities. Furthermore, brains from QTC-4-MeOBnE-treated mice had a significant increase in adult neurogenesis and remyelination through Prox1/NeuroD1 and Wnt/beta-catenin pathways. Overall, our findings support the potential anti-AD effect of QTC-4-MeOBnE through multiple pathways, all of which have been involved in the onset and progression of the disease.

Discovery of fast-acting dual-stage antimalarial agents by profiling pyridylvinylquinoline chemical space via copper catalyzed azide-alkyne cycloadditions

To identity fast-acting, multistage antimalarial agents, a series of pyridylvinylquinoline-triazole analogues have been synthesized via CuAAC. Most of the compounds display significant inhibitory effect on the drug-resistant malarial Dd2 strain at low submicromolar concentrations. Among the tested analogues, compound 60 is the most potent molecule with an EC50 value of 0.04 +/- 0.01 mu M. Our current study indicates that compound 60 is a fast-acting antimalarial compound and it demonstrates stage specific action at the trophozoite phase in the P. falciparum asexual life cycle. In addition, compound 60 is active against both early and late stage P. falciparum gametocytes. From a mechanistic perspective, compound 60 shows good activity as an inhibitor of beta-hematin formation. Collectively, our findings suggest that fast-acting agent 60 targets dual life stages of the malarial parasites and warrant further investigation of pyridylvinylquinoline hybrids as new antimalarials.

Insights into corrosion inhibition mechanism of mild steel in 1 M HCl solution by quinoxaline derivatives: electrochemical, SEM/EDAX, UV-visible, FT-IR and theoretical approaches

Three quinoxaline-based heterocycles namely, 6-methyl-2,3-diphenyl-quinoxaline (Q-CH3), 6-nitro-2,3-diphenylquinoxaline (Q-NO2) and 2,3-diphenylquinoxaline (Q-H) were evaluated as inhibitor for mild steel (MS) in 1 M HCl. Inhibition effectiveness of the Q-H, Q-CH3 and Q-NO2 tested using different computational simulations and experimental methods. Results showed that inhibition effectiveness of Q-H, Q-CH3 and Q-NO2 increases with their concentration. Polarization results showed that Q-H, Q-CH3 and Q-NO2 displayed anodic-type behaviour. Inhibition efficiencies of Q-H, Q-CH3 and Q-NO2 followed the order: 87.6% (Q-NO2) < 90.2% (Q-CH3)< 92.4% (Q-H) for Q-CH3. Presence of both electron withdrawing (-NO2) and donating (-CH3) substituents decrease the inhibition efficiency as compared to the parent compound however in decrease in protection power is more prominent in the presence of -NO2 substituent. Q-H, Q-CH3 and Q-NO2 inhibit corrosion by adsorbing on MS surface and their adsorption mode followed Langmuir adsorption isotherm. Adsorption of Q-H, Q-CH3 and Q-NO2 on metallic surface reinforced with SEM-EDS and UV-visible studies of MS surfaces. Interaction mechanism of QH, Q-CH3 and Q-NO(2 )with MS surface and their mode of adsorption was studies using DFT and MD (MD) simulations, respectively. Negative sign of adsorption energies (E-ads) for Q-H, Q-CH3 and Q-NO2 suggested that they adsorb spontaneously over MS surface. Interested yet?

Metal-Free Tandem Approach for Triazole-Fused Diazepinone Scaffolds via [3+2]Cycloaddition/C-N Coupling Reaction

A novel metal-free, efficient cascade reaction has been developed to construct 1,2,3-triazole-fused 1,4-diazepinone skeletons. Mechanism investigation indicated that sodium azide has not only served as a 1,3-dipoles synthon in [3 + 2] cycloaddition but also prompted C-N bond formation. Furthermore, the potential utility of this protocol was demonstrated by scale-up synthesis of 1,2,3-triazole-fused diazepinone derivatives and the derivatization of them.

The present work encompasses the synthesis of novel heterogeneous magnetic nanocatalyst(IL@CuFe2O4L Tyr-TiO2/TiTCIL)and its characterization by Fourier-transform infrared spectroscopy (FTIR), high resolution transmission electron microscopy (HR-TEM), field emission gun scanning electron microscopy (FEG-SEM), energy-dispersive X-ray spectroscopy (EDX), vibrating sample magnetometry (VSM), X-ray powder diffraction (P-XRD), X-ray photoelectron spectroscopy (XPS), photoluminescence spectroscopy and Raman spectroscopy. XPS analysis confirms the presence of Cu as Cu1+ and Cu2+ by the effect of the linker in IL@CuFe(2)O(4)LTyr-TiO2/TiTCIL. It provides an eco-friendly procedure with several advantages such as operational simplicity, water as the solvent, short reaction time, easy workup and excellent yields in the synthesis of 1,4-disubstituted-1,2,3-triazoles via Click reaction. The catalyst showed recyclability up to seven runs in Click reaction and the recycled catalyst was also characterized by HR-TEM, FEG-SEM and XPS. In Click reaction, one single crystal of 1-benzyl-4-phenyl-1H-1,2,3-triazole was grown. Its energetic features, non-covalent interactions, molecular electrostatic potential surfaces, and packing arrangement were calculated by using the B3LYP-D3/def2-TZVP level of theory and the Bader’s quantum theory of Atoms in molecules (QTAIM). Moreover, IL@CuFe(2)O(4)LTyr-TiO2/TiTCIL also displayed good photocatalytic activity in the degradation of methylene blue dye in visible light. (c) 2020 Elsevier B.V. All rights reserved.

Rapid and Simple Reversed-Phase High-Performance Liquid Chromatography (RP-HPLC) Method for Simultaneous Quantifications of Triazole Antifungals in Human Serum

Purpose To develop and validate a one-step, rapid and simple reversed-phase high-performance liquid chromatography (HPLC)-based protocol for the simultaneous measurement of voriconazole (VCZ), posaconazole (POSA), itraconazole (ITC) in serum/plasma. Methods Calibration standards (CS) and quality control samples were prepared in drug-free serum by spiking with the triazoles at different concentrations. HPLC was performed with C-18 column, isocratic mobile phase after extraction with cold acetonitrile. The standardized method was tested in 2693 patients’ serum/plasma samples. Results Linearity of CS for ITC, VCZ and POSA was proportional to the nominal concentration (correlation coefficient > 0.999). Limit of detection (mg/L) for ITC, VCZ and POSA was 0.25, 0.25 and 0.125, respectively. The lower limit of quantification (mg/L) for ITC, VCZ and POSA was 0.5, 0.5 and 0.25, respectively. Precision and accuracy were in acceptable range with 100% average percentage recovery. No interferences from endogenous substances and other antimicrobial compounds were noted. In clinical samples, the therapeutic range achieved for VCZ was 39.9%. Whereas, 61.1% and 44% of samples with ITC and POSA, respectively, were in the sub-therapeutic range. Conclusion We developed a rapid and simple HPLC method to quantify common triazoles in a single chromatographic run allowing simultaneous measurement of different antifungals in a small volume of serum/plasma. Thus, therapeutic drug monitoring requests can be processed in one run without changing the protocol parameters, column or column conditioning thereby improving turnaround time.

Degradation pathway of triazole fungicides and synchronous removal of transformation products via photo-electrocatalytic oxidation tandem MoS2 adsorption

A simple and effective tandem process of photo-electrocatalytic oxidation (PECO)-MoS2 adsorption was developed for the synchronous removal of triazole fungicides (TFs) and toxicological transformation products (TPs). In order to accurately identify trace TPs and evaluate degradation pathway during water treatment, a sensitive analytical method was developed on the basis of the stir bar sorptive extraction (SBSE) pretreatment tandem LC-MS/MS technique. Firstly, the typical TFs (PRO, TET, and DIN, C-0 = 1.0 mg/L) in actual water samples were treated under the optimal process (bias voltage 1.8 V, pH 4, irradiation intensity 50 mW/cm(2), 0.05 g MoS2/100 mL, 350 rpm, adsorption of 5 min). The result indicated that the residues of PRO, TET, and DIN in secondary effluent were 0.0973, 0.0617, and 0.0012 mg/L, respectively, with the removal rates of 90.3%, 93.8%, and 99.9%, respectively, undergoing 30-min photo-electrocatalysis and 5-min adsorption. The alkaline medium was favorable for the adsorption of MoS2 to TFs. The assessment results of potential cancer risk indicated that the residues of TFs in secondary effluent were safe for drinking water consumption. Besides, the major TPs were identified via the SBSE-HRLC-MS/MS technique, and one possible transformation pathway of TFs was proposed. TFs mainly underwent dehydrochlorination, cyclization, hydroxylation, etc. to produce a series of nitrogenous heterocyclic compounds that possess higher polarity than parents, hinting that TPs might pose potential aquatic toxicity. However, TPs can be removed synchronously by this tandem technique. The current study can provide a theoretical basis for the harmless treatment of TFs in the water environment.
