Neutral Chiral Tetrakis-Iodo-Triazole Halogen-Bond Donor for Chiral Recognition and Enantioselective Catalysis

Halogen bonding represents a powerful tool in the field of noncovalent interactions. However, applications in enantioselective recognition and catalysis remain almost nonexistent, due in part to the distinct features of halogen bonds, including long covalent and noncovalent bond distances and high directionality. Herein, this work presents a novel chiral tetrakis-iodo-triazole structure as a neutral halogen bond donor for both chiral anion-recognition and enantioinduction in ion-pair organocatalysis. NMR-titration studies revealed significant differences in anion affinity between the halogen bonding receptor and its hydrogen bonding parent. Selective recognition of chiral dicarboxylates and asymmetric induction in a benchmark organocatalytic reaction were demonstrated using the halogen bond donor. Inversions in the absolute sense of chiral recognition, enantioselectivity, and chiroptical properties relative to the related hydrogen donor were observed. Computational modeling suggested that these effects were the result of distinct anion-binding modes for the halogen- versus hydrogen-bond donors.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 584-13-4, in my other articles.

Design, synthesis, anticancer and antioxidant activities of amide linked 1,4-disubstituted 1,2,3-triazoles

To explore anticancer and antioxidant agents with improved potency, we synthesized a series of amide linked 1,4-disubstituted 1,2,3-triazoles through click chemistry approach. The structure of synthesized triazoles were characterized by- FTIR, H-1 NMR, C-13 NMR spectroscopy and HRMS. All the synthesized compounds were screened for their anticancer activity against four different cell lines- PC3 (prostate cancer), A549 (lung cancer), MIAPACA (liver cancer), Fr2 (Breast epithelial), reflecting compounds 7e and 7f to possess good activity. The antioxidant activity was evaluated by using stable free radical 1,1-diphenyl-2-picrylhydrazyl (DPPH) assay and compound 7d showed promising activity having IC50 value 1.61 mu g/ml. Molecular docking studies of compounds 7e and 7f was carried out in active site of human epidermal growth factor receptor 2 revealed high binding affinities and within toxicity limits. The experimental results were in good agreement with docking studies. In-silico ADME studies of synthesized compounds also have good dispositional profile and are patient compliant, may be potential future candidates for anticancer treatment. (C) 2020 Elsevier B.V.

Design, Synthesis, Evaluation and Molecular Docking Studies of Novel Triazole Linked 1,4-Dihydropyridine-isatin Scaffolds as Potent Anticancer Agents

A series of novel triazole linked isatin-dihydropyridine hybrids (N1-N15) have been synthesized and examined for their anti proliferative activity against human cancer cell lines viz. HeLa, Huh-7, PC-3, IMR-32 and MCF-7. All of the synthesized hybrids have shown moderate to potent cytotoxicity against all the tested cell lines except IMR-32. Compounds N1, N2 and N13 have displayed an enhanced inhibitory potency against Huh-7 cell line as compared to the standard drug, doxorubicin. Out of the three, N2 has shown the highest in vitro inhibitory action with IC50 values of 6.73 +/- 0.33 mu M and 17.94 +/- 0.23 mu M against Huh-7 and MCF-7 cell lines, respectively. The docking studies of these most potent compounds have also been investigated which identified that N2 might be an excellent drug-like candidate worthy of further pursuit.

Separation of chalcopyrite from galena with 3-amyl-4-amino-1, 2, 4-triazole-5-thione collector: Flotation behavior and mechanism

3-Amyl-4-amino-1,2,4-triazole-5-thione (AATT) reacted with Cu2+ or Pb2+ ions in aqueous solutions to form CuAATT and Pb(AATT)(2) complexes and their solubility product constants were measured as 10(-16.17) and 10(-20.60), respectively. In the moderately-alkaline media, both chalcopyrite and galena chemisorbed AATT on to their surfaces, and the adsorption amount of AATT on chalcopyrite was bigger than that on galena, which rendered a stronger hydrophobization toward chalcopyrite. While under the high-alkaline pulp, AATT only chemisorbed on chalcopyrite, not on galena. The micro-flotation findings indicated that AATT was a favorable collector for flotation enrichment of chalcopyrite and galena at pH <11.0, and realized an efficient flotation separation of chalcopyrite from galena under pH>11.5. The CuAATTcomplex was more insoluble than Pb(AATT)2, which implied a stronger affinity of AATT toward chalcopyrite than galena and returned their selective flotation separation at the high-alkaline condition.

Copper(II) and Zinc(II) Complexes with the Clinically Used Fluconazole: Comparison of Antifungal Activity and Therapeutic Potential

Copper(II) and zinc(II) complexes with clinically used antifungal drug fluconazole (fcz), {[CuCl2(fcz)(2)](.)5H(2)O}(n), 1, and {[ZnCl2(fcz)(2)]Greek ano teleia2C(2)H(5)OH}(n), 2, were prepared and characterized by spectroscopic and crystallographic methods. The polymeric structure of the complexes comprises four fluconazole molecules monodentately coordinated via the triazole nitrogen and two chlorido ligands. With respect to fluconazole, complex 2 showed significantly higher antifungal activity against Candida krusei and Candida parapsilosis. All tested compounds reduced the total amount of ergosterol at subinhibitory concentrations, indicating that the mode of activity of fluconazole was retained within the complexes, which was corroborated via molecular docking with cytochrome P450 sterol 14 alpha-demethylase (CYP51) as a target. Electrostatic, steric and internal energy interactions between the complexes and enzyme showed that 2 has higher binding potency to this target. Both complexes showed strong inhibition of C. albicans filamentation and biofilm formation at subinhibitory concentrations, with 2 being able to reduce the adherence of C. albicans to A549 cells in vitro. Complex 2 was able to reduce pyocyanin production in Pseudomonas aeruginosa between 10% and 25% and to inhibit its biofilm formation by 20% in comparison to the untreated control. These results suggest that complex 2 may be further examined in the mixed Candida-P. aeruginosa infections.

Copolymers of Methyl Acrylate and Vinylazoles: Synthesis, Thermolabile Properties, and Grafting of Polyamine Chains

New copolymers of methyl acrylate with 1-vinylimidazole, 1-vinyl-1,2,4-triazole, and 4-vinyl-1,2,3-triazole are synthesized by radical copolymerization. It is shown that the reactivity ratios for methyl acrylate and 1-vinylimidazole are 0.83 +/- 0.09 and 0.25 +/- 0.02, for methyl acrylate and 1-vinyl-1,2,4-triazole are 1.0 +/- 0.04 and 0.27 +/- 0.01, and for methyl acrylate and (4-vinyl-1H-1,2,3-triazolyl)-methyl pivalate are 0.56 +/- 0.03 and 2.90 +/- 0.20, respectively. The behavior of the copolymers in aqueous media and their thermoresponsive properties are studied by potentiometric titration and dynamic light scattering. Copolymer macromolecules occur in aqueous solutions in the form of large associates the fraction of which increases upon heating; in some cases, an insoluble phase is formed. It is found that the copolymers with the grafted oligopropylamine moieties containing N-vinylazole units can interact with the DNA oligonucleotide, stimulating their research as agents for the delivery of nucleic acids to living cells.

Fluorinated Triazole Foldamers: Folded or Extended Conformational Preferences

Fluorinated peptidomimetic foldamers are still in their infancy. We report here the easy access to fluorinated triazolamers based on 2-amino-3,3,3-trifluoropropyl-1,4-triazolyl acetic acid (CF3-1,4-Tz) and on aminomethyl-1,4-triazolyl-difluoroacetic acid (1,4-Tz-CF2). Both CF3-1,4-Tz and 1,4-Tz-CF2 amino acids were efficiently prepared by copper(I)-catalyzed Huisgen 1,3-dipolar cycloaddition. Their conformational preferences were studied by 2D NMR analyses and molecular dynamic simulations. Foldamers based on CF3-1,4-Tz amino acids are capable of adopting short multi-stranded beta-sheet-like structures that are maintained by electrostatic interactions between the triazole proton and N2 atom of neighboring subunits. On the contrary, foldamers based on 1,4-Tz-CF2 units adopt elongated beta-strand-like structures, stabilized by electrostatic interaction between fluorine atoms and their neighboring protons.

Novel triazole derivatives as ecological corrosion inhibitors for mild steel in 1.0 M HCl: experimental & theoretical approach

The present paper illustrates the investigation of two novel ecological triazole derivative corrosion inhibitors, namely ethyl 2-(4-phenyl-1H-1,2,3-triazol-1-yl) acetate [Tria-CO2Et], and 2-(4-phenyl-1H-1,2,3-triazol-1-yl) acetohydrazide [Tria-CONHNH2]. The studied inhibitors were investigated against the corrosion of mild steel in 1.0 M HCl solution using different electrochemical techniques. Potentiodynamic polarization experiments indicated that the [Tria-CO2Et], and the [Tria-CONHNH2] acted as mixed type inhibitors. Electrochemical impedance spectroscopy measurements revealed that both inhibitors presented a high inhibition performance, achieving an inhibition efficiency of 95.3% for [Tria-CO2Et] and 95.0% for [Tria-CONHNH2] at a concentration of 1.0 x 10(-3) M. Based on the Langmuir isotherm model and the activation parameters, these triazole derivatives were adsorbed onto a steel surface by physical and chemical bonds. Density functional theory based on B3LYp6-311G(d,p) was also carried out to correlate the inhibition efficiencies obtained experimentally with the theoretical descriptors of the studied molecular structures.

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 584-13-4 is helpful to your research. Computed Properties of C2H4N4.

The Three-Component Synthesis of 4-Sulfonyl-1,2,3-triazoles via a Sequential Aerobic Copper-Catalyzed Sulfonylation and Dimroth Cyclization

4-Sulfonyl-1,2,3-triazole scaffolds possess promising bioactivities and applications as anion binders. However, these structures remain relatively unexplored and efficient synthetic procedures for their synthesis remain desirable. A practical room-temperature, aerobic copper-catalyzed three-component reaction of aromatic ketones, sodium sulfinates, and azides is reported. This procedure allows for facile access to 4-sulfonyl-1,5-disubstituted-1,2,3-triazoles in yields ranging from 34 to 89%. The reaction proceeds via a sequential aerobic copper(II)chloride-catalyzed oxidative sulfonylation and the Dimroth azide-enolate cycloaddition.

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 288-88-0. Recommanded Product: 1H-1,2,4-Triazole.
