Category: triazoles. The article was titled 《Design, synthesis, and antifungal activity of carboxamide derivatives possessing 1,2,3-triazole as potential succinate dehydrogenase inhibitors》. The information in the text is summarized as follows:

Succinate dehydrogenase (SDH) is demonstrably one of the most important mol. targets in development of new fungicide. In our continuous efforts to discover novel SDH inhibitors, forty-two carboxamide derivatives containing 1,2,3-triazole ring were designed and synthesized, which were precisely characterized by 1H NMR, ESI-MS, elemental anal. and X-ray single-crystal diffraction. The compounds were screened for antifungal activities against phytopathogenic fungi by mycelia growth inhibition assay in vitro. Compound A3-3 exhibited significant antifungal activity against Sclerotinia sclerotiorum, Botrytis cinerea, Rhizoctonia cerealis and Gaeumannomyces graminsis with EC50 values of 1.08, 8.75, 1.67 and 5.30μg/mL, resp., comparable to those of com. SDHI boscalid. In vivo testing demonstrated that A3-3 was effective for suppressing rape sclerotinia rot, cucumber gray mold and wheat powdery mildew caused by S. sclerotiorum, B. cinerea and Blumeria graminis at a dosage of 200μg/mL. Inhibition activities against SDH test proved the designed analogs were effective in the enzyme level. The mol. docking simulation revealed that A3-3 interacted with ARG43, TYR58 and TRP173 of the SDH through hydrogen bond and pi-pi interaction, which could explain the probable mechanism of action between the inhibitor and target protein.1H-1,2,3-Triazole(cas: 288-36-8Category: triazoles) was used in this study.

And the article was published in Organic & Biomolecular Chemistry in 2019. Formula: C30H30N10 The author mentioned the following in the article:

The anti-malarial drug artemisinin (ART) possesses potent antiinflammatory activity, yet its underlying mechanism of action has remained elusive. Here the authors employed quant. chem. proteomics to in situ profile the cellular targets of ART and identified heat shock protein 90 (HSP90) as a direct target. Further study revealed that ART suppressed the production of nitric oxide (NO) in macrophages via inhibiting the interaction between HSP90 and inducible NO synthase (iNOS).Tris((1-benzyl-1H-1,2,3-triazol-4-yl)methyl)amine(cas: 510758-28-8Formula: C30H30N10) was used in this study.

The author of 《Preparation of multifunctional glycopolymers using double orthogonal reactions and the effect of electrostatic groups on the glycopolymer-lectin interaction》 were Oh, Takahiro; Jono, Kazuki; Kimoto, Yuri; Hoshino, Yu; Miura, Yoshiko. And the article was published in Polymer Journal (Tokyo, Japan) in 2019. Quality Control of Tris((1-benzyl-1H-1,2,3-triazol-4-yl)methyl)amine The author mentioned the following in the article:

We investigated synthetic biomacromols. to control mol. interactions. Multifunctional glycopolymers for mol. recognition were prepared via living radical polymerization and post-click chem. with orthogonal Huisgen and thiol-epoxy reactions. The synthesis of the polymer backbone and the subsequent side-chain introduction successfully proceeded in high yield. The multifunctional glycopolymers had a tri-block structure: the first and third blocks contained mannose, and the second block contained either a pos. or neg. charged group or a neutral hydrophilic group. The mol. recognition of the glycopolymers toward lectin was evaluated via fluorescence quenching measurements. Because of the electrostatic interaction, the binding constant varied in the following order: pos. charged glycopolymer (PT110) > neg. charged glycopolymer (NT110). The effect of the electrostatic interactions was modest compared with the effect of the carbohydrate-lectin binding. These results suggested that the carbohydrate-lectin interaction was an important factor in the mol. recognition of glycopolymers. This study provides guidelines for the preparation of multifunctional polymers, such as biomaterials.Tris((1-benzyl-1H-1,2,3-triazol-4-yl)methyl)amine(cas: 510758-28-8Quality Control of Tris((1-benzyl-1H-1,2,3-triazol-4-yl)methyl)amine) was used in this study.

Li, Mingyue; Fu, Yaomei; You, Siqi; Yang, Yu; Qin, Chao; Zhao, Liang; Su, Zhongmin published an article in 2021. The article was titled 《Hexanuclear nickel-based [P4Mo11O50] with photocatalytic reduction of CO2 activity》, and you may find the article in Inorganic Chemistry Communications.Related Products of 288-36-8 The information in the text is summarized as follows:

A new polyoxometalate based organic-inorganic hybrid [Ni6(trz)2(Htrz)13][H4P4Mo11O50]·7H2O (1), constructed from a hexanuclear [Ni6(trz)2(Htrz)13] building block and a new polyoxometalate [H4P4Mo11O50] cluster, was synthesized under a hydrothermal condition. In this 3D structure, each [Ni6(trz)2(Htrz)13] secondary building unit (SBU) connects with four neighbored [Ni6(trz)2(Htrz)13] and four [H4P4Mo11O50] clusters, forming an eight-connected node. While each [H4P4Mo11O50] cluster bridges four [Ni6(trz)2(Htrz)13] SBUs as a four-connected node. So the 3D framework of 1 can be simplified to a binodal (4,8)-connected gsp2 topol. with point symbol [44·62][416·612]. The photocatalytic reduction of CO2 under visible light reveals that the highest yield of CO was 689.86μmol g-1 when 1 is used as catalyst, Ru(bpy)3Cl2 as a photosensitizer and TEOA as a sacrificial agent. The mechanism of the photoreduction of CO2 is confirmed by Mott-Schottky, photocurrent, and fluorescence quenching experiments This research provides a new strategy for the design of cheap and efficient POM-based photocatalysts.

Recommanded Product: 288-36-8In 2019 ,《Complexes of Zn(II)-Triazoles with CO2 and H2O: Structures, Energetics, and Applications》 was published in Journal of Physical Chemistry A. The article was written by Dahmani, Rahma; Grubisic, Sonja; Yaghlane, Saida Ben; Boughdiri, Salima; Hochlaf, Majdi. The article contains the following contents:

Using a first-principle methodol., DFT-M05-2X(+D3), we investigate the stable structures of the nonreactive and reactive clusters formed between Zn2+-triazoles ([Zn2+-Tz]) clusters and CO2 and/or H2O. In sum, we characterized two modes of bonding of [Zn2+-Tz] with CO2/H2O: the interaction is established through (i) a covalent bond between Zn2+ of [Zn2+-Tz] and oxygen atoms of CO2 or H2O and (ii) hydrogen bonds through N-H or C-H of [Zn2+-Tz] and oxygen atoms of H2O or CO2, N-H···O. We also identified intramol. proton transfer processes induced by complexation. Indeed, water drastically changes the shape of the energy profiles of the tautomeric phenomena through strong lowering of the potential barriers to tautomerism. The comparison to [Zn2+-Im] subunits formed with Zn2+ and imidazole shows that the efficiency of Tz-based compounds for CO2 capture and uptake is due to the incorporation of more accessible nitrogen donor sites in Tzs compared to imidazoles. Since [Zn2+-Tz] clusters are subunits of an organometallic nanoporous materials and Zn-proteins, our data are useful for deriving force fields for macromol. simulations of these materials. Our work also suggests the consideration of traces of water to better model the CO2 sequestration and reactivity on macromol. entities such as pores or active sites.

The article was written by Zhang, Aigui; Leonard, Peter; Seela, Frank. The article contains the following contents:

Anomeric base pairs in heterochiral DNA with strands in the α-D and β-D configurations and homochiral DNA with both strands in α-D configuration were functionalized. The α-D anomers of 2′-deoxyuridine and 7-deaza-2′-deoxyadenosine were synthesized and functionalized with clickable octadiynyl side chains. Nucleosides were protected and converted to phosphoramidites. Solid-phase synthesis furnished 12-mer oligonucleotides, which were hybridized. Pyrene click adducts display fluorescence, a few of them with excimer emission. Tm values and thermodn. data revealed the following order of duplex stability α/α-D≫β/β-D≥α/β-D. CD spectra disclosed that conformational changes occur during hybridization. Functionalized DNAs were modeled and energy minimized. Clickable side chains and bulky click adducts are well accommodated in the grooves of anomeric DNA. The investigation shows for the first time that anomeric DNAs can be functionalized in the same way as canonical DNA for potential applications in nucleic acid chem., chem. biol., and DNA material science.

The article conveys some information:

We characterized two key biosynthetic intermediates of the intriguing rubterolone family (tropolone alkaloids) that contain a highly reactive pyran moiety (in equilibrium with the hydrolyzed 1,5-dione form) and undergo spontaneous pyridine formation in the presence of primary amines. We exploited the intrinsic reactivity of the pyran moiety and isolated several new rubterolone derivatives, two of which contain a unique thiazolidine moiety, e.g., I. Three rubterolone derivatives were chem. modified with fluorescence and biotin tags using peptide coupling and click reaction. Overall, eight derivatives were fully characterized by HRMS/MS and 1D and 2D NMR spectroscopy and their antimicrobial, cytotoxic, anti-inflammatory and antiparasitic activities evaluated.

In 2015,Neuner, Sandro; Santner, Tobias; Kreutz, Christoph; Micura, Ronald published 《The “”Speedy”” Synthesis of Atom-Specific 15N Imino/Amido-Labeled RNA》.Chemistry – A European Journal published the findings.Electric Literature of C12H22F6N6OP2 The information in the text is summarized as follows:

Although numerous reports on the synthesis of atom-specific 15N-labeled nucleosides exist, fast and facile access to the corresponding phosphoramidites for RNA solid-phase synthesis is still lacking. This situation represents a severe bottle-neck for NMR spectroscopic investigations on functional RNAs. Here, we present optimized procedures to speed up the synthesis of 15N(1)adenosine and 15N(1)guanosine amidites, which are the much needed counterparts of the more straightforward-to-achieve 15N(3) uridine and 15N(3) cytidine amidites in order to tap full potential of 1H/15N/15N-COSY experiments for directly monitoring individual Watson-Crick base pairs in RNA. Demonstrated for two preQ1 ribo-switch systems, we exemplify a versatile concept for individual base-pair labeling in the anal. of conformationally flexible RNAs when competing structures and conformational dynamics are encountered.

Sialic acid sugars on mammalian cells regulate numerous biol. processes, while aberrant expression of sialic acid is associated with diseases such as cancer and pathogenic infection. Inhibition of the sialic acid biosynthesis may therefore hold considerable therapeutic potential. To effectively decrease the sialic acid expression, we synthesized C-5-modified 3-fluoro sialic acid sialyltransferase inhibitors. We found that C-5 carbamates significantly enhanced and prolonged the inhibitory activity in multiple mouse and human cell lines. As an underlying mechanism, we have identified that carbamate-modified 3-fluoro sialic acid inhibitors are more efficiently metabolized to their active cytidine monophosphate analogs, reaching higher effective inhibitor concentrations inside cells.
