Synthesis, characterization and cytotoxic activity evaluation of 4-(1,2,3-triazol-1-yl) salicylic acid derivatives

A novel series of 4-(1,2,3-triazol-1-yl) salicylic acid derivatives was synthesized from 4-azidosalicylic acid and diverse alkynes using copper catalyzed azide-alkyne cycloaddition as key process and fully characterized by using different analytical techniques. The in vitro antiproliferative activity of these new compounds was explored against a series of tumoral cell lines which included U251 (human glioblastoma), PC-3 (human prostate cancer cell line), K562 (human leukemia), HCT-15 (human colorectal adenocarcinoma), MCF-7 (human breast adenocarcinoma) and SKLU (human lung adenocarcinoma), showing selective activity in some compounds. Moreover, molecular docking studies suggest a strong interaction between ARG-154 in STAT3 and the triazole fragment which can explain the inhibitory activity observed in these compounds.

3-Amino-1,2,4-triazole-derived graphitic carbon nitride for photodynamic therapy

Graphitic carbon nitride (g-C3N4) has been shown as a promising visible-light photosensitizer for photodynamic therapy (PDT) application. Nevertheless, its therapeutic efficiency is limited by the low efficiency of visible-light utilization. To overcome this issue, 3-amino-1,2,4-triazole-derived graphitic carbon nitride nanosheets (g-C3N5 NSs) are prepared for PDT application. The addition of nitrogen-rich triazole group into the g-C3N4 motif significantly makes the light absorption of g-C3N5 NSs red-shift with the band gap down to 1.95 eV, corresponding to a absorption edge at a wavelength of 636 nm. g-C3N5 NSs generate superoxide anion radicals (O-2(center dot-)) and singlet oxygen (O-1(2)) under the irradiation of a low-intensity white light emitting diode. Owing to the high efficiency of visible-light utilization, g-C3N5 NSs show about 9.5 fold photocatalytic activity of g-C3N4 NSs. In vitro anticancer studies based on the results of CCK-8 assay, Calcein-AM/PI cell-survival assay and photo-induced intracellular ROS level analysis in living HeLa cells demonstrate the potential of g-C3N5 NSs as a low-toxic and biocompatible high-efficient photosensitizer for PDT.

Root Uptake of Imidacloprid and Propiconazole Is Affected by Root Composition and Soil Characteristics

Residual pesticides in soil may be taken up by crops and negatively affect food safety. The uptake mechanism of imidacloprid and propiconazole was studied using wheat roots. The factors affecting root uptake were also studied with different crops and in different soils. Imidacloprid and propiconazole were taken up by wheat roots mainly through the symplastic and apoplastic pathways, respectively. Root protein and lipid contents were the main factors affecting the uptake and accumulation of imidacloprid and propiconazole by different crop roots, respectively. The uptake of imidacloprid and propiconazole in soil by wheat plants was linearly correlated with their concentrations in soil pore water, which were governed by soil characteristics. These results are helpful for understanding and estimating crop uptake of residual pesticides in soils.

Resistance to demethylation inhibitors in Cercospora beticola, a pathogen of sugar beet in Japan, and development of unique cross-resistance patterns

Cercospora beticola Sacc. is the most destructive pathogen of sugar beet (Beta vulgaris L.) and causes Cercospora leaf spot (CLS). Since 1986, fungicides that function as demethylation inhibitors (DMIs) have been used to control CLS in Hokkaido, which is the only area in Japan where sugar beet is grown. Reduced sensitivity of C. beticola to DMI fungicides, based on the half maximal effective concentration (EC50), was first reported in Hokkaido in 1999, however the fungicides continued to be used effectively until 2014. In a field experiment in 2016, we found that the efficacy of difenoconazole against the field population of C. beticola was greatly reduced. We subsequently tested over 600 isolates collected throughout the sugar beet-growing region of Hokkaido and revealed that the mean resistance factor of four DMI fungicides (difenoconazole, fenbuconazole, tebuconazole, and tetraconazole) were high, which indicates that DMI-resistant isolates were distributed throughout the beet cultivation area. Moreover, we identified three types of isolates that have unique cross-resistance patterns between difenoconazole and fenbuconazole, with their EC50 rate (= difenoconazole EC50/ fenbuconazole EC50) converged to 31, 4.0, and 0.40, respectively, which appeared to be affected by the local history of fungicide usage. The F144L substitution in CbCYP51 was only found in the group whose EC50 rate was 0.40. This is the first report of DMI resistance in C. beticola in Japan, and the findings in this study could contribute to our understanding of the mechanism of DMI resistance.

Two 2p-3d-4f complexes constructed from functionalized nitronyl nitroxides: Synthesis, structure and magnetic properties

Two 2p-3d-4f complexes of [LnCu(hfac)(5)NIT-Ph-p-OCH(2)trz](n) (Ln = Gd (1), Ho (2); NIT-Php-OCH(2)trz = 2-(4-((1H-1,2,4-triazol-1-yl)methoxy)phenyl)-4,4,5,5-tetramethylimidazoline-1-oxyl-3-oxide; hfac = hexafluoroacetylacetonate) have been successfully synthesized through Cu(hfac)(2) and Ln(hfac)(3) reacting with nitronyl nirtroxide radical of NIT-Ph-p-OCH(2)trz. The structures of complexes 1 and 2 were elucidated by single-crystal X-ray structural analysis and the results show that both complexes consist of [Ln-NIT-Ln-NIT](n) one-dimensional chains and the additional Cu ions are coordinated to the nitrogen atoms from the triazole rings of the radical ligands. The ferromagnetic couplings are observed between the coordinated NO group and Ln (III) ions. Ac magnetic susceptibilities indicate that the Ho derivatives displays frequency-dependent out-of-phase signals. (C) 2020 Elsevier B.V. All rights reserved.

Resorcin[4]arene-based Cu(I) binuclear and mononuclear complexes as efficient catalysts for azide-alkyne cycloaddition reactions

In this study, three fascinating resorcin[4]arene-based Cu(I) complexes, named [CuCl (TPC4R)] (1), [CuBr (TPC4R)] (2), and [Cu2I2(TPC4R)] (3) were prepared by using a pyrimidine-functionalized resorcin[4]arene ligand (TPC4R). In 1 and 2, two Cu(I) ions were linked by two TPC4R and two Cl- (or Br-) anions to form binuclear units. The adjacent units were extended into supramolecular layers through H bonds. In 3, two Cu(I) ions were connected by one TPC4R and two I- anions to form a mononuclear complex. The mononuclear units were connected by hydrogen bonds to produce a supramolecular chain. Significantly, 1 and 2 exhibit high efficiency and universality for azide-alkyne cycloaddition reactions in the synthesis 1,2,3-triazoles and beta-OH-1,2,3-triazoles. It has been found that the amount of catalyst, solvent type and reaction temperature have considerable influences on the activities of catalytic systems. The conversions of catalysts 1 and 2 could reach 99% for most of the selected substrates. It was found that after repeatedly used for 4 times, the catalytic activity of 1 did not decrease apparently.

Dissipation and dietary risk assessment of tristyrylphenol ethoxylate homologues in cucumber after field application

The potential for tristyrylphenol ethoxylates (TSPEOs) residues to contaminate crops or be released into the environment is of increasing concern, as they are toxic to living organisms. This study determined the dissipation of TSPEO homologues in cucumber under field conditions. TSPEOn (n = 6-29) dissipated more rapidly in cucumber than in soil samples, with half-lives of 1.80-4.30 d and 3.73-6.52 d, respectively. Short-chain TSPEOn (n = 6-11) persisted for longer than other oligomers in soil. Concentrations of the final residues (Sigma TSPEOs) in cucumber and soil were 24.3-1349 mu g/kg and 47.3-1337 mu g/kg, respectively. TSP15EO or TSP16EO was the dominant oligomer, with concentrations of 2.30-150 mu g/kg. The risk assessment showed that the acute and chronic dietary exposure risks of Sigma TSPEOs in cucumber were 0.03-0.57% and 0.05-0.39%, respectively, suggesting little or no health risk to Chinese consumers.

Recent developments in 1,2,3-triazole-based chemosensors

Chemosensors are synthetic chemical compounds that have the ability to selectively bind with analytes of interest and produce detectable changes in, for example, their color, fluorescence, or redox potential. In this review, the latest developments in the field of chemosensors based on click generated triazoles used for a range of metal cations, anions, and neutral analytes have been summarized. The detection of metal ions has become a major field of research due to their medicinal, biological, and environmental impact. Recently, the number of articles published in this area of research has significantly increased, which have reported more reliable and sophisticated triazole-based chemosensors for a variety of analytes of interest. From this perspective, a constant accumulation of research work is needed (or acceptable) so as to produce a collection of chromophores that will assist researchers to rapidly access the current developments in this research field. This feature article focuses on the development of chemosensors based on click generated triazoles reported between 2012 and 2020, including metal cations, anions, and other small organic molecules due to their advantages over other chemosensors, which include ease of recognition, simple instrumentation, high selectivity, and high sensitivity.

Impact of N-Substituent and pK(a) of Azole Rings on Fuel Cell Performance and Phosphoric Acid Loss

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.

A luminescent zinc-organic framework as bifunctional chemosensors for detection of nitrobenzene and Fe3+

A luminescent zinc metal-organic framework with uncoordinated triazolate N-donors, namely [Zn (tba)(2)]center dot DMA (1, DMA = N,N-dimethylacetamide), has been successfully synthesized under solvothermal conditions by using a triazolate-carboxylate bifunctional ligand, 4-(1H-1,2,4-triazol-1-yl)ebenzoic acid (Htba). Single-crystal X-ray diffraction analysis reveals that compound 1 displays a 4-fold interpenetrating dia framework with 1D dumbbell-shaped channels. The systematic luminescence experiments reveal that 1 can be potentially used as a fast-response fluorescence sensor for the sensitive detection of nitrobenzene and Fe3+ ion through drastic fluorescence quenching. Moreover, the quenching mechanisms of 1 towards nitrobenzene and Fe3+ were also investigated.
