Synthesis of biologically important 4-Phenyl-C-glycosyl-1,2,3-triazole derivatives by Cu(I)-catalyzed azide-alkyne cycloaddition

A new series of 4-phenyl-C-glycosyl-1,2,3-triazoles were synthesized using Cu(I)- catalyzed azide-alkyne cycloaddition. The key step in the synthesis involved the coupling of unprotected glycosyl azides with substituted C-glycosylated phenyl acetylenes. Using o-phenylenediamine as a ligand, we could significantly reduce the reaction time, improve the product yield, and simplify the purification process. Broad substrate scope in terms of sugars was achieved.

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.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 381-98-6 is helpful to your research. Computed Properties of C4H3F3O2.

Exposure to fungicide difenoconazole reduces the soil bacterial community diversity and the co-occurrence network complexity

Difenoconazole is a triazole fungicide that is widely used worldwide and has been frequently detected in agricultural soils, but its ecotoxicological effect on soil bacterial community remains unknown. Here, the degradation of difenoconazole and its effect on soil bacterial communities were investigated at three concentrations in five different agricultural soils. Difenoconazole degraded faster in non-sterilized soils than in sterilized soils, suggesting that biodegradation is a major contributor to the dissipation of difenoconazole in soils. Exposure to high concentrations of difenoconazole decreased the soil bacterial community diversity in most soils, and this influence was aggravated with the increasing concentration. The effect of difenoconazole on soil bacterial community diversity was also enhanced with the increasing content of organic matter and total nitrogen in soils. Moreover, difenoconazole exposure also reduced the soil bacterial community network complexity and exhibited a concentration-dependent characteristic. In addition, a core bacterial community (57 operational taxonomic units, OTUs) was identified, and some core OTUs were strongly linked to the degradation of difenoconazole in soils. It is concluded that high concentrations of difenoconazole may have a significant effect on the soil bacterial communities, and co-occurrence networks may improve the ecotoxicological risk assessment of fungicides on soil microbiome.

Synthesis, in silico ADME, molecular docking and in vitro cytotoxicity evaluation of stilbene linked 1,2,3-triazoles

Series of (E)-1-benzyl-4-((4-styrylphenoxy)methyl)-1H-1,2,3-triazoles 7a-x were obtained by Wittig reaction between 4-((1-benzyl-1H-1,2,3-triazol-4-yl)methoxy)benzaldehydes 5a-d and benzyl triphenyl phosphonium halides 6a-f in benzene. The structures of the synthesized compounds were confirmed by FTIR, NMR (H-1 and C-13 NMR)spectroscopy, and mass spectrometry. All synthesized compounds were screened for their cytotoxic activity against human cancer cell lines including pancreatic carcinoma, colorectal carcinoma, lung carcinoma, and leukemias such as acute lymphoblastic, chronic myeloid, and non-Hodgkinson lymphoma cell lines. In vitro cytotoxicity data showed that compounds 7c, 7e, 7h, 7j, 7k, 7r, and 7w were moderately cytotoxic (11.6 -19.3 mu M) against the selected cancer cell lines. These cytotoxicity findings were supported using molecular docking studies of the compounds against 1TUB receptor. The drug-likeness properties of the compounds evaluated by in silico ADME analyses. Resveratrol linked 1,2,3-triazoles were more sensitive towards human carcinoma cell lines but least sensitive towards leukemia and lymphoma cell lines.

Enzymatic glycosylation of bioactive acceptors catalyzed by an immobilized fungal beta-xylosidase and its multi-glycoligase variant

A recombinant beta-xylosidase (rBxTW1) from the ascomycete Talaromyces amestolkiae and a mutant derived from it, with mostly synthetic activity, have been immobilized as magnetic cross-linked enzyme aggregates (mCLEAs). The mCLEAs of rBxTW1 kept the excellent hydrolytic and O-transxylosylating activities of the free enzyme and had improved thermal and pH stability. The mCLEAs of the mutant also maintained or improved the catalytic properties of the soluble enzyme, synthetizing the O-xylosides of vanillin and (-)-epigallocatechin gallate, and the N- and S-xyloside of 3,5-dibromo-1,2,4-triazole and thiophenol, respectively. The mCLEAs were recyclable across 4 cycles of synthesis of the O-xylosides through a green and highly selective process. The magnetic properties of the scaffold used for immobilization may allow the easy recovery and reuse of the biocatalyst even from reactions containing insoluble lignocellulosic biomass.

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.

Click chemistry based synthesis, cytotoxic activity and molecular docking of novel triazole-thienopyrimidine hybrid glycosides targeting EGFR

In the current study, new thienopyrimidine conjugates bearing 1,2,3-triazole core and different sugar moieties have been designed and synthesized by Cu(I)-catalysed click dipolar cycloaddition. The cytotoxic activity of the synthesised conjugates 2, 5, 7, and 13-18 was studied against HCT-116 and MCF-7 cell lines by the MTT assay. The triazole glycosides 16 and 18 provided significant cytotoxic activities against HCT-116 cell lines comparable to that of doxorubicin and other studied compounds. The cytotoxic behaviour against MCF-7 exhibited that all the investigated compounds were more potent than doxorubicin. Moreover, all screened targets were evaluated against mutant EGFR kinase type L858R and the results revealed that the acetylated 1,2,3-triazole glycosides 13-18 exhibited excellent EGFR inhibitory activity in comparison with gefitinib. Furthermore, molecular modelling studies were performed to investigate the binding affinity of the most active compounds to EGFR enzyme.
