In the past five years, our team had been committed to click chemistry research, exploring the biological activity of 1,2,3-triazole by synthesizing different target inhibitors. In this study, a series of novel indole-2-one derivatives based on 1,2,3-triazole scaffolds were synthesized for the first time, and their inhibitory activity on vascular endothelial growth factor receptor-2 (VEGFR-2) was tested. Most of the compounds had shown promising activity in the VEGFR-2 kinase assay and had low toxicity to human umbilical vein endothelial cells (HUVECs). The compound 13d (IC50 = 26.38 nM) had better kinase activity inhibition ability than sunitinib (IC50 = 83.20 nM) and was less toxic to HUVECs. Moreover, it had an excellent inhibitory effect on HT-29 and MKN-45 cells. On the one hand, by tube formation assay, transwell, and Western blot analysis, compound 13d could inhibit VEGFR-2 protein phosphorylate on HUVECs, thereby inhibiting HUVECs migration and tube formation. In vivo study, the zebraflsh model with VEGFR-2 labeling also verified that compound 13d had more anti-angiogenesis ability than sunitinib. On the other hand, molecular docking and molecular dynamics (MD) simulation results showed that compound 13d could stably bind to the active site of VEGFR-2. Based on the above findings, compound 13d could be considered an effective anti-angiogenesis drug and has more development value than sunitinib. (C) 2020 Elsevier Masson SAS. All rights reserved.

The influence of N-substituent and pK(a) of azole rings has been investigated for the performance of high-temperature polymer electrolyte membrane fuel cells (HT-PEMFCs). Imidazole, benzimidazole, and triazole groups were functionalized on the side chains of poly(phenylene oxide), respectively. Each azole group is categorized by their N-substituent into two types: unsubstituted and methyl-substituted azoles. The membranes with methyl-substituted azoles showed higher phosphoric acid (PA) doping levels with an average increase of 20% compared to those with unsubstituted azoles in the full-doped states. However, unsubstituted azoles more effectively improved the proton conductivity and the membrane with unsubstituted imidazole (IMPPO-H) showed a high anhydrous proton conductivity of 153 mS/cm at 150 degrees C. In contrast, the membranes with methyl-substituted azoles showed a higher PA retention with an average increase of 81% compared to those with unsubstituted azoles. The higher PA retention of methyl-substituted azoles also led to the higher fuel cell performance with the maximum increase of 95% in the power density. It was also revealed that higher pK(a) of azoles enhanced the PA retention and the fuel cell performance. Based on the experimental results of PA retention and density functional theory calculations, the PA loss mechanism was also proposed.

Application of 5445-51-2, Catalysts allow a reaction to proceed via a pathway that has a lower activation energy than the uncatalyzed reaction. 5445-51-2, Name is Cyclobutane-1,1-dicarboxylic acid, SMILES is OC(=O)C1(CCC1)C(O)=O, belongs to triazoles compound.

The effect of different ancillary ligands and counterions in platinum(II) complexes has been investigated. Based on the previously reported tridentate C<^>N<^>N ligand precursor 2-(1-benzyl-1H-1,2,3-triazol-4-yl)-6-phenylpyridine (HL), the photophysical properties of complexes of the type [Pt(L)(X)](n+) have been varied by changing the fourth (monodentate) ligand (X) of the square-planar platinum(II) complexes. Different lifetimes and quantum yields were observed, depending on the identity of this ancillary ligand. The most favorable photophysical properties within this series of complexes were obtained for neutral complexes with the phenylacetylido ligand with a quantum yield of 35% and a lifetime of 2.22 mu s, while for cationic complexes bearing nitrile, isonitrile and triphenylphosphane units gave comparable results with quantum yields ranging from 11% to 16% and lifetimes from 3.59 mu s to 4.93 mu s. Introducing a ferrocene moiety attached to an acetylido ligand, the complex became hardly emissive. The investigated counterions perchlorate, tetrafluoroborate and hexafluorophosphate of positively charged complexes regarding their photophysical properties were found to affect the non-radiative decay rates. To understand the minor effect observed for the emission maxima of the complexes, density functional theory (DFT) was applied. The experimental emission spectra of the complexes were reproduced by using simplified model systems. The distribution of the frontier orbitals used for the description of the emissive T-1 state in its optimized geometry mainly involves the tridentate luminophore rather than the ancillary ligand. This explains why the emission is dominated by the pincer unit with perturbative participation of the metal center while excluding significant influence of the ancillary ligand.

This study involves synthesis and physicochemical evaluation of triazole conjugated silver nanoparticles (TBS-AgNPs). The triazole derivative (TBS) was synthesized via click reaction followed by its conjugation with silver nanoparticles through the chemical reduction method. The TBS-AgNPs were characterized by various spectroscopic techniques, for instance, UV-Visible, atomic force microscopy (AFM), Fourier transform infrared (FTIR),and dynamic light scattering (DLS). TBS-AgNPs showed maximum absorption at 400 nm with an average particle size of 60-80 nm. Sensitivity and selectivity of TBS-AgNPs towards metal ions were evaluated using UV-Visible spectroscopy and the addition of Pd2+ produced a significant decrease in absorption intensity of TBS-AgNPs. Whereas, all other tested metal ions such as Sn2+, Ni2+, Ca2+, Bi3+, NH4+, K+, Mg2+, Na+, Co2+, Mn2+, and Ba2+ did not alter the optical properties of TBS-AgNPs for Pd2+. TBS-AgNPs nanoparticles are highly selective for Pd2+ as no interference was observed in competitive experiments. Job’s plot indicated a 1:1 binding ratio between Pd2+ and TBS-AgNPs. Furthermore, TBS-AgNPs were effectively used for the detection of Pd2+ ion in laboratory tap water. (C) 2020 Elsevier B.V. All rights reserved.

Let’s face it, organic chemistry can seem difficult to learn. Especially from a beginner’s point of view. Like 288-88-0, Name is 1H-1,2,4-Triazole. In a document, author is Dionizio, Thais Petizero, introducing its new discovery. Quality Control of 1H-1,2,4-Triazole.

The fuel cell is a continuously operating, low environmental impact, highly energy-efficient electrochemical device that has been cited as a clean energy source to replace fossil fuels. However, noble metals, such as platinum, are used as electrocatalysts to improve reaction kinetics, which raises the cost of this renewable energy source. This work aimed to evaluate a graphite paste electrode, modified with a copper(II) coordination compound containing N,O-donor groups, as an electrocatalyst in oxygen reduction reactions (ORR) and its catalase-like activity. Through electrochemical analyses, such as cyclic voltammetry and chronoamperometry, the modified electrode activity was investigated at different pH values and scan rates. Catalase activity was also investigated at different pH values in order to establish which would be the most active. The modified electrode proved to be a promising electrocatalyst in ORR in alkaline medium, and the copper(II) complex actively degraded hydrogen peroxide under alkaline conditions, which can help to increase the lifetime of the fuel cell device.

The insufficient intracellular H2O2 level in tumor cells is closely associated with the limited efficacy of chemodynamic therapy (CDT). Despite tremendous efforts, engineering CDT agents with a straightforward and secure H2O2 supplying ability remains a great challenge. Inspired by the balance of H2O2 generation and elimination in cancer cells, herein, a nanozyme-based H2O2 homeostasis disruptor is fabricated to elevate the intracellular H2O2 level through facilitating H2O2 production and restraining H2O2 elimination for enhanced CDT. In the formulation, the disruptor with superoxide dismutase-mimicking activity can convert O-2(center dot-) to H2O2, promoting the production of H2O2. Simultaneously, the suppression of catalase activity and depletion of glutathione by the disruptor weaken the transformation of H2O2 to H2O. Thus, the well-defined system could perturb the H2O2 balance and give rise to the accumulation of H2O2 in cancer cells. The raised H2O2 level would ultimately amplify the Fenton-like reaction-based CDT efficiency. Our work not only paves a way to engineer alternative CDT agents with a H2O2 supplying ability for intensive CDT but also provides new insights into the construction of bioinspired materials.

Background: Advanced glycation end products (AGEs) are known to be involved in the pathophysiology of diabetic complications, neurodegenerative diseases, and aging. Preventing the formation of AGEs can be helpful in the management of these diseases. Objectives: Two classes of previously synthesized traizole Schiff’s bases (4H-1,2,4-triamle-4-Schiff’s bases 1-14, and 4H-1,2,4-triazole-3-Schiff’s bases 15-23) were evaluated for their in vitro antiglycation activity. Methods: In vitro fructose-mediated human serum albumin (HSA) glycation assay was employed to assess the antiglycation activity of triazole Schiff’s bases. The active compounds were subjected to cytotoxicity analysis by MTT assay on mouse fibroblast (3T3) cell line. Molecular docking and simulation studies were carried out to evaluate the interactions and stability of compounds with HSA. Anti-hyperglycemic and antioxidant activities of selected non-cytotoxic compounds were evaluated by in vitro a-glucosidase inhibition, and DPPH free radical scavenging assays, respectively. Results: Compound 1 (IC50 =47.30 +/- 0.38 mu M) from 4H-1,2,4-triazole-4-Schiff’s bases has exhibited antiglycation activity comparable to standard rutin (IC50 =54.5 +/- 0.05 mu M) along with a stable RMSD profile in MD simulation studies. Compound 1 also exhibited a potent a-glucosidase inhibitory activity, and moderate antioxidant property. Other derivatives showed a weak antiglycation activity with IC50 values between 248.1-637.7 mu M. Compounds with potential antiglycation profile were found to be non-cytotoxic in a cellular assay. Conclusion: The study identifies triazole Schiff s bases active against fructose-mediated glycation of HSA, thus indicates their potential against late diabetic complications due to production of advancedend products (AGEs).

This work contributes to the growing interest in predictions linked with energetic salts. A reliable method to accurately compute the heat of formation of triazole-based salts was investigated. Calculations were based on Born-Haber energy cycles: gas-phase enthalpy of ions and lattice enthalpy were calculated separately. Ten triazole-based salts were synthesized and fully characterized. Their heat of combustion was measured by bomb calorimeter. Gas-phase heat of formation of cations and anions were computed at four different levels of theory: B3LYP 6-31G(d,p), CBS-4M, CBS-QB3, and G4. Ionic volumes were calculated at the B3LYP 6-31G(d,p) level with and without corrections. Lattice enthalpy estimations, based on calculated ionic volumes, were performed with the help of Jenkins and Gutowski methods. Combinations of the obtained results (gas-phase enthalpy of ions and lattice enthalpy) were used in the Born-Haber approach to predict solid phase enthalpy of formation of studied energetic salts. Direct comparison with experimental measurements enabled the identification of the most reliable path for energetic salt standard enthalpy of formation prediction.
