Regioselective 1,3-Dipolar Cycloaddition of Nitriles with Nitrile Imines Generated from Tetrazoles

A synthesis of 3,5-disubstituted-1,2,4-triazoles from nitriles and 5-aryltetrazoles is reported. When 5-aryltetrazoles are triflylated in the presence of nitriles, the resulting 5-aryl-2-triflyltetrazoles thermally generate N-triflyl-nitrile imines through a sequence of ring-chain tautomerization and denitrogenation. The N-triflyl-nitrile imines immediately undergo 1,3dipolar cycloaddition with nitriles in a regioselective manner, forming the corresponding 1,2,4-triazoles.

Evaluation of corrosion protection performance and mechanical properties of epoxy-triazole/graphene oxide nanocomposite coatings on mild steel

In this research, graphene oxide (GO) functionalized with 3-amino-1, 2, 4-triazole-5 thiol (ATT) [fGO] has been synthesized for the achievement of a high protection performance of epoxy coatings with enhanced mechanical properties. A novel combination of fGO/epoxy composite coating will be a promising application for the corrosion protection of steel. The corrosion protection evaluation of fGO-grafted epoxy composite coatings on mild steel is investigated using electrochemical impedance spectroscopy (EIS) and scanning electrochemical microscopy (SECM). EIS revealed high film resistance, charge transfer resistance and low capacitance for the fGO-grafted epoxy-coated mild steel. SECM analysis showed less current distribution (0.5-2.5 I/nA) at the scratched surface of fGO-grafted composite coatings compared to neat epoxy coatings (2-10 I/nA) on mild steel. The presence of sulfur and nitrogen atoms in the fGO facilitates the enhanced corrosion protection performance of epoxy-fGO-coated mild steel. Mechanical properties of the coatings were also found to be improved in the presence of modified GO particles as evidenced by hardness test and pull-out adhesion test.

Design and Synthesis of Novel Imidazole Derivatives Possessing Triazole Pharmacophore with Potent Anticancer Activity, and In Silico ADMET with GSK-3 beta Molecular Docking Investigations

A library of novel imidazole-1,2,3-triazole hybrids were designed and synthesized based on the hybrid pharmacophore approach. Therefore, copper(I)catalyzed click reaction of thiopropargylated-imidazole 2 with several organoazides yielded two sets of imidazole-1,2,3-triazole hybrids carrying different un/functionalized alkyl/aryl side chains 4a-k and 6a-e. After full spectroscopic characterization using different spectral techniques (IR, H-1, C-13 NMR) and elemental analyses, the resulted adducts were screened for their anticancer activity against four cancer cell lines (Caco-2, HCT-116, HeLa, and MCF-7) by the MTT assay and showed significant activity. In-silico molecular docking study was also investigated on one of the prominent cancer target receptors, i.e., glycogen synthase kinase-3 beta (GSK-3 beta), revealing a good binding interaction with our potent compound, 4k and was in agreement with the in vitro cytotoxic results. In addition, the ADMET profile was assessed for these novel derivatives to get an insight on their pharmacokinetic/dynamic attributes. Finally, this research design and synthesis offered click chemistry products with interesting biological motifs mainly 1,2,3 triazoles linked to phenyl imidazole as promising candidates for further investigation as anticancer drugs.

Synthesis, in vitro evaluation, and computational simulations studies of 1,2,3-triazole analogues as DPP-4 inhibitors

Novel 1,2,3-triazole analogues (S7 similar to S10) were synthesized and evaluated for their inhibitory activity against hDPP-4. All the 1,2,3-triazole analogues exhibited moderate in vitro hDPP-4 inhibitory activities (265 similar to 780 nM). These results are somewhat less potent compared to those of known 1,2,3-triazole analogues (S1 S6, 14 254 nM). S2 and S3 manifested excellent potency against hDPP-4 with IC(50)s of 28 and 14 nM, respectively. The role of the 1,2,3-triazole moiety in binding the molecule to the target was investigated using combined 10 1,2,3-triazole analogues (S1 S10). Molecular dynamics (MD) simulations following the aforementioned docking phase were performed to elucidate potential binding modes of sitagliptin’s 1,2,3-triazole analogues in hDPP-4, with the use of a cocrystal structure of hDPP-4 with sitagliptin (PDB ID: 1X70). Docking and MD simulations of the complexes of hDPP-4 with sitagliptin, S2 and S3 suggest that Glu205, Glu206, Tyr662, and Tyr666 would be the key amino acid residues for the binding of the molecules with the receptor. Especially, S2 and S3 showed additional strong pi-pi interaction between Phe357 and 1,2,3-triazole. Same strong pi-pi interaction is also observed between Phe357 and the 1,2,4-triazole ring of sitagliptin. Furthermore, additional interactions with Tyr547, Cys551, and especially Arg358 would enhance the binding affinity of the compounds for the pocket of the enzyme. In overall, in vitro hDPP-4 inhibitory activities of synthetic 1,2,3-triazole analogues were well matched with results of computational simulations studies.

Bacterial diversity and enzymatic activity in a soil recently treated with tebuconazole

Tebuconazole is one of the most commonly used active substances from the group of triazoles, that exhibits high efficacy in plant protection against fungal diseases. It’s too frequent use may, however, pose risk to soil ecosystems, leading to changes in their biological diversity. This study was aimed at evaluating the effect of tebuconazole on population numbers, diversity, and structure of bacterial communities, and on the enzymatic activity of soil. Tebuconazole was introduced into the soil (sandy loam with pH 7.0) in the following doses in mg kg(-1) DM (dry matter) of soil: 0.00 (C), 0.02 (O), and 10.0 (T). It caused changes in the population numbers of diversity of bacteria as well as in the biochemical activity of soil. It stimulated the proliferation of organotrophic bacteria and inhibited that of actinobacteria. The r-strategists were found to predominate among both the organotrophs and actinobacteria in the soil with tebuconazole addition. The amplicon sequencing of the 16S encoding gene (SSU rRNA) demonstrated tebuconazole to elicit changes in the structure of bacterial communities. In all soil samples, the prevailing taxon at the Phylum level turned out to be Proteobacteria, followed by Firmicutes and Actinobacteria, whereas the lowest counts were noted for Verrucomicrobia. The relative abundance of the bacteria at the Phylum level decreased in the soil under the influence of tebuconazole. The most sensitive to the effect of tebuconazole applied in a dose of 10.0 mg kg(-1) turned out to be Acidobacteria, whereas the most resistant were Verrucomicrobia. The predominating taxon at the class level was Alphaproteobacteria, followed by Bacilli. Tebuconazole ensured favorable conditions for the development of bacteria from Kaistobacter and Bacillus genera as their OTUs were the highest in the soil treated with tebuconazole at 10.0 mg kg(-1). In turn, Phenylobacterium and Rhodoplanes were sensitive to soil treatment with tebuconazole at doses of 0.02 mg kg(-1) and 10.0 mg kg(-1). Tebuconazole proved to be a strong inhibitor of urease and catalase activities, while in turn it enhanced activities of dehydrogenases, acid phosphatase, alkaline phosphatase, and arylsulfatase.

Assembly of four modules onto a tetraazide platform by consecutive 1,2,3-triazole formations

Efficient consecutive 1,2,3-triazole formations using multiazide platforms are disclosed. On the basis of unique clickability of the 1-adamantyl azido group, a four-step synthesis of tetrakis(triazole)s was achieved from a tetraazide platform molecule. This method was applied to a convergent synthesis of tetrafunctionalized probes in a modular synthetic manner.

Preparation of crosslinker-free anion exchange membranes with excellent physicochemical and electrochemical properties based on crosslinked PPO-SEBS

The process of crosslinking is widely employed to increase the physicochemical stability of anion exchange membranes and, in some cases, improve ion conductivity. For a general case in which a polymer is crosslinked by a crosslinking agent, the physicochemical properties of the polymer can be greatly altered, depending on the type of crosslinking agent. In this study, we induced crosslinking without a crosslinking agent to intentionally maximise various physical properties (i.e., mechanical properties, swelling ratios, and so forth) of two commercially-available polymers. A triazole was incorporated into the conducting group to maximise the ion conductivity, especially under room humidity (RH) conditions. The crosslinked PPO-SEBS membranes prepared through this approach were not only capable of forming very thin membranes (10 mu m thickness) with excellent physical properties (34.3 MPa of tensile strength and 91.6% of elongation at break) but also exhibited high hydroxide ion conductivity under 95% RH, and conductivity plays an important role in achieving good fuel cell performance. When the membrane electrode assembly (MEA), as fabricated utilising a crosslinked PPO-SEBS membrane and a platinum on carbon (Pt/C) catalyst on each electrode, was operated in conditions with a H-2/O-2 gas flow and a 60 degrees C temperature, a stable fuel cell performance was obtained for a long period of time (300 hours) at a maximum power density of 405 mW cm(-2). This result surpasses the performance of commercialized AEMs and is comparable with the performance levels of cutting-edge AEMs when operated under similar conditions.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 705-86-2. Quality Control of 6-Pentyltetrahydro-2H-pyran-2-one.

Peptide Nucleic Acid with Double Face: Homothymine-Homocytosine Bimodal C alpha-PNA (bm-C alpha-PNA) Forms a Double Duplex of the bm-PNA(2):DNA Triplex

C alpha-bimodal peptide nucleic acids (bm-C alpha-PNA) are PNAs with two faces and are designed homologues of PNAs in which each aminoethylglycine (aeg) repeating unit in the standard PNA backbone hosts a second nucleobase at C alpha through a spacer chain with a triazole linker. Such bm-C alpha-PNA with mixed sequences can form double duplexes by simultaneous binding to two complementary DNAs, one to the base sequence on t-amide side and the other to the bases on the C alpha side chain. The synthesis of bm-C alpha-PNA with homothymine (T-7) on the t-amide face and homocytosine (C-5) on the C alpha side chain through the triazole linker was achieved by solid phase synthesis with the global click reaction. In the presence of complementary DNAs dA(8) and dG(6) at neutral pH, bm-C alpha-PNA 1 forms a higher order pentameric double duplex of a triplex composed of two bmC alpha-PNA-C-5:dG(5) duplexes built on a core (bm-Ca-PNA-T-7)(2):dA(8) triplex. Circular dichroism studies showed that assembly can be achieved by either triplex first and duplex later or vice versa. Isothermal titration calorimetry data indicated that the assembly is driven by favorable enthalpy. These results validate concurrent multiple complex formation by bimodal PNAs with additional nucleobases at C alpha or C gamma on the aeg-PNA backbone and open up ways to design programmed supramolecular assemblies.
