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.

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.

A Facile Total Synthesis of Mubritinib

A five-step, practical, and concise total synthesis of mubritinib is described. The synthesis utilized Friedel-Crafts acylation, click reaction, reduction, and demethylation for the construction of the triazole ring system as key steps. Another important feature of this synthesis is the Bredereck oxazole synthesis. The main advantages of this process are the improved yield and decreased number of reaction steps, which paves the way for the industrial-scale synthesis of mubritinib.

Do fungicides affect the physiology, reproductive development and productivity of healthy soybean plants?

Fungicides are widely used to control diseases in soybean crops. We hypothesized that fungicides applied to healthy soybean plants compromise the plant’s physiology, affect the reproductive process and reduce crop productivity. We aimed to evaluate the photosynthetic process, pollen grain viability and yield components of soybean plants exposed to three commercial fungicides. The experiment was performed twice using soybean cultivar SYN 1378C, disease-free plants, with four treatments: i) control treatment (without any fungicide application); ii) cyproconazole 150 g L-1 + difenoconazole 250 g L-1 (CPZ + DFZ; 250 mL ha(-1); without adjuvant); iii) azoxystrobin 300 g Kg(-1) + benzovindiflupyr 150 g Kg(-1) (AZB + BZP; 200 g ha(-1); Nimbus (R) adjuvant (Syngenta)); and iv) propiconazole 250 g L-1 + difenoconazole 250 g L-1 (PPZ + DFZ; 150 mL ha(-1); without adjuvant) in both soybean pre-bloom (V8) and bloom (R1) developmental stages. The experimental design was randomized blocks with four replicates. Phytotoxicity, gas exchange and chlorophyll a fluorescence traits, pollen grain viability, pollen grain germination, flower abortion and soybean production components were evaluated. The fungicides did not affect the physiological traits, pollen grain germination and crop yield.

Synthesis, characterization and fluorescent properties of ferrocenyl pyrazole and triazole ligands and their palladium complexes

The search for new fluorescent materials with high quantum yields has been the focus of research, considering the diverse applications that fluorescent materials present. In this study, ferrocenyl pyrazolyl (L1) and ferrocenyl triazolyl (L2) ligands and their palladium metal complexes (1 and 2) were synthesized to investigate their fluorescence properties. While the pyrazolyl ligand was prepared through a ligand substitution reaction, synthesis of the triazolyl derivative involved the [3 + 2] azide-alkyne using click chemistry. All the prepared compounds have been characterized by NMR and IR spectroscopy, elemental analysis, mass spectrometry and single-crystal X-ray crystallography. These air-stable compounds were prepared in moderate to good yields (70% and 83%). The ferrocenyl-pyrazolyl L1 and ferrocenyl-triazolyl L2 ligands showed near-infrared (NIR) emission bands with quantum yields of 20% and 26% respectively. The addition of the Pd2+ ions results in the reduction of fluorescence intensity and quantum yield. Such fluorescent properties demonstrate their potential use in bio-analysis and as fluorogenic probing. (C) 2020 Elsevier B.V. All rights reserved.

Rh-Catalyzed Formal [3+2] Cyclization for the Synthesis of 5-Aryl-2-(quinolin-2-yl)oxazoles and Its Applications in Metal Ions Probes

Main observation and conclusion A facile and efficient strategy for the synthesis of 5-aryl-2-(quinolin-2-yl)oxazoles via rhodium-catalyzed formal [3+2] cyclization of 4-aryl-1-tosyl-1H-1,2,3-triazoles with quinoline-2-carbaldehydes has been described. The protocol employs mild conditions and offers good yields of diverse 2,5-aryloxazole derivatives with a broad reaction scope. It is amenable to gram-scale synthesis and easily transformation. Moreover, this 5-aryl-2-(quinolin-2-yl)oxazole skeleton is indeed a new fluorophore and its applications in metal ions probes are also investigated and showed fluorescent responses to mercury ion.

Synthesis of (Z)-3-((5-(benzylthio)-4H-1,2,4-triazol-3-yl)imino)-5-haloindolin-2-one derivatives: combined spectroscopic and computational investigations on the level and activity of matrix metalloproteinases 2 and 9 in cancer cell lines

Angiogenesis is an essential factor for cancer progression. Although more attention is paid in angiogenesis on its role in cancer biology, many other non-neoplastic diseases are also angiogenic-dependent. Recently, there is motivation to control cancer via inhibition of angiogenesis. Isatin-based scaffolds have been extensively used as anticancer agents in the recent years. Although some biological properties of isatin-based scaffolds are determined, their effects on angiogenesis are rare. So, we investigated the antiangiogenic effects of isatin-1,2,4-triazole conjugates. (Z)-3-((5-(benzylthio)-4H-1,2,4-triazol-3-yl)imino)-5-haloindolin-2-one macromolecules 1a-1l were synthesized and characterized, and the buffered solutions were used for evaluation of their cytotoxicity (cell viability) by MTT assay in vitro against U87MG (human glioblastoma astrocytoma) and A2780 (human ovarian carcinoma) cancer cell lines. Also, the effects of the compounds 1a-1l on supernatants activities and levels of matrix metalloproteinases (MMP-2 and MMP-9) were assayed using enzyme-linked immunosorbent assay (ELISA) and gelatin zymography. The compounds 1j-1l have the greatest cytotoxicity against studied cell lines. Moreover, our observations indicated that 1j-1l decreased the supernatants activity of MMP-2 and MMP-9 more than the others and all of the tested compounds considerably decreased the supernatant levels of MMP-9. The molecular mechanism of 1j binding to MMP-2 and MMP-9 was investigated by fluorescence quenching, absorption spectroscopy, FT-IR, molecular docking and molecular dynamics (MD) simulation procedures.

Synthesis and characterization of biologically important quinoline incorporated triazole derivatives

Triazoles are well recognized in literature for their significant biologically active heterocyclic compounds. Also the quinoline nucleus found in several natural products shows a varied biological activity. Keeping in the view of these observations, a novel series of 6/7/8-substtuted-2-[(5-((4-chlorophenoxy)methyl)-4H-1,2,4-triazol-3-yl)thiolquinoline-3-carbaldehydes and 6/7/8-substituted-2-[(5-(pyridin-4-yl)-4H-1,2,4-triazol-3-yl)thio]quinoline-carbaldehydes were synthesized by the condensation of 5-(4-chloro phenoxy methyl)-2,4-dihydro-1,2,4-triazole-3-thiones and 5-(pyridin-3-yl)-4H-1,2,4-triazole-3-thiols with 6/7/8-substituted-2-chloro quinoline-3-carbaldehydes. The new series were established by Mass, NMR and IR spectroscopy and were also screened for their antimicrobial activities. A few of the novel compounds exhibited tremendous bioactivities compared to that of normal drug. (C) 2020 Elsevier B.V. All rights reserved.

Understanding the regioselectivity of the copper(I)- and ruthenium(II)- catalyzed [3+2] cycloadditions of azido derivative of ribose with terminal alkyne: a theoretical study

In the present work, the uncatalyzed, the copper(I)-catalyzed and the ruthenium(II)-catalyzed [3 + 2] cycloadditions (32CA) of azido derivative of ribose with terminal alkyne leading to 1,4- and/or 1,5- 1,2,3-triazole regioisomers have been studied at the B3LYP level of theory in combination with the LanL2DZ basis set for Cu, Ru and Cl atoms and the standard 6-31G(d) basis set for other atoms. The obtained results reveal that the uncatalyzed reaction requires high and similar activation energies, namely 18.29 and 18.80 kcal/mol for the 1,4 and 1,5 regioisomeric pathways, respectively, indicating a very limited regioselectivity in agreement with the experimental outcomes. Interestingly, for the copper(I)-catalyzed azide-alkyne cycloaddition (CuAAC), investigated using the Fokin stepwise mechanism involving two copper atoms, the 1,4 regioisomeric reaction path found to be kinetically more favored than the 1,5 regioisomeric reaction path by 9.13 kcal/mol. By contrast, for the ruthenium(II)-catalyzed azide-alkyne cycloaddition (RuAAC), investigated using the Fokin mechanism using the pentamethylcyclopentadienyl ruthenium chloride [Cp * RuCl] complex, the 1,5 regioisomeric reaction path is more favored than the 1,4 regioisomeric reaction path by 3.48 kcal/mol. The present work puts in evidence the determinant role of Cu/Ru catalysts in the regioselectivity of this click reaction.

5-[Aryloxypyridyl (or nitrophenyl)]-4H-1,2,4-triazoles as novel flexible benzodiazepine analogues: Synthesis, receptor binding affinity and lipophilicity-dependent anti-seizure onset of action

A new series of 5-(2-aryloxy-4-nitrophenyl)-4H-1,2,4-triazoles and 5-(2-aryloxy-3-pyridyl)-4H-1,2,4-triazoles, possessing C-3 thio or alkylthio substituents, was synthesized and evaluated for their benzodiazepine receptor affinity and anti-seizure activity. These analogues revealed similar to significantly superior affinity to GABA(A)/benzodiazepine receptor complex (IC50 values of 0.04-4.1 nM), relative to diazepam as the reference drug (IC50 value of 2.4 nM). To determine the onset of anti-seizure activity, the time-dependent effectiveness of i.p. administration of compounds on pentylenetetrazole induced seizure threshold was studied and a very good relationship was observed between the lipophilicity (cLogP) and onset of action of studied analogues (r(2) = 0.964). The minimum effective dose of the compounds, determined at the time the analogues showed their highest activity, was demonstrated to be 0.025-0.1 mg/kg, relative to diazepam (0.025 mg/kg).
