Polarity-Tolerant Chloride Binding in Foldamer Capsules by Programmed Solvent-Exclusion

Persistent anion binding in a wide range of solution environments is a key challenge that continues to motivate and demand new strategies in synthetic receptor design. Though strong binding in low-polarity solvents has become routine, our ability to maintain high affinities in high-polarity solvents has not yet reached the standard set by nature. Anions are bound and transported regularly in aqueous environments by proteins that use secondary and tertiary structure to isolate anion binding sites from water. Inspired by this principle of solvent exclusion, we created a sequence-defined foldameric capsule whose global minimum conformation displays a helical folded state and is preorganized for 1:1 anion complexation. The high stability of the folded geometry and its ability to exclude solvent were supported by solid-state and solution phase studies. This capsule then withstood a 4-fold increase in solvent dielectric constant (epsilon(r)) from dichloromethane (9) to acetonitrile (36) while maintaining a high and solvent-independent affinity of 10(5) M-1; Delta G similar to 28 kJ mol(-1). This behavior is unusual. More typical of solvent-dependent behavior, Cl- affinities were seen to plummet in control compounds, such as aryl-triazole macrocycles and pentads, with their solvent-exposed binding cavities susceptible to dielectric screening. Finally, dimethyl sulfoxide denatures the foldamer by putative solvent binding, which then lowers the foldamer’s Cl- affinity to normal levels. The design of this capsule demonstrates a new prototype for the development of potent receptors that can operate in polar solvents and has the potential to help manage hydrophilic anions present in the hydrosphere and biosphere.

Synthesis and bio-evaluation of new multifunctional methylindolinone-1,2,3-triazole hybrids as anti-Alzheimer’s agents

In view of the multifactorial nature of Alzheimer’s disease, a new series of methylindolinone-1,2,3-triazole derivatives (7a-n) were efficiently prepared and evaluated for their in vitro cholinesterase inhibitory activity. Although most synthesized compounds showed weak acetylcholinesterase inhibitory activity, they depicted moderate to good activity against butyrylcholinesterase. The IC50 value for anti-BuChE activity of compound 7k was calculated as 4.78 mu M which was more potent than the reference drug donepezil (5.19 mu M). Based on the molecular docking evaluation, it was found that compound 7k could bind simultaneously to the peripheral and catalytic sites of BuChE. Also, the optimal compound 7k was further assessed as a BACE1 inhibitor and neuroprotective agent. (C) 2020 Elsevier B.V. All rights reserved.

Axially chiral bis-1,2,3-Triazol-4-ylidene-Ag(I)-MIC and, bis-Au(I)-MIC complexes of (R)-BINOL and (-)-Menthol scaffold: Synthesis, structure, and characterizations

Herein, we report the novel axially chiral bis-Ag(I)-MIC and, bis-Au(I)-MIC complexes bearing axially chiral bis-1,2,3-triazolium-derived mesoionic carbene (tz-MIC) ligands were synthesized. The enantiopure R-BINOL was employed as a basic unit to synthesize a axially chiral bis-1,2,3-triazolium-derived mesoionic carbene (tz-MIC) ligands (1-2)a. In particular, the axially chiral bis-1,2,3-triazolium-derived mesoionic carbene (tz-MIC) ligands (1-2)a, were obtained from the reaction of corresponding bis-1,2,3-triazole ligand precursor with methyl and ethyl iodide in 82-90% yields. Novel axially chiral bis-Ag(I)-MIC complexes (1 – 2)b, were prepared by the treatment of corresponding axially chiral bis-1,2,3-triazolium-derived mesoionic carbene (tz-MIC) iodide salts, (1 – 2)a, with Ag2O via in-situ deprotonation method in 69-86% yields. Novel axially chiral bis-Au(I)-MIC complex-2c was synthesized from their respective novel axially chiral bis-Ag(I)-MIC complex-2b, using transmetallation reaction with (SMe2)AuCl in 70% yield. All these novel axially chiral bis-Ag(I)-MIC and bis-Au(I)-MIC complexes were isolated for the first time and structurally characterized by H-1 NMR and C-13{H-1)-NMR spectroscopy, FT-IR spectroscopy, mass spectrometry, elemental analysis, specific optical rotation and, single crystal X-ray crystallography.

4-Substituted-1,2,3-triazolo nucleotide analogues as CD73 inhibitors, their synthesis, in vitro screening, kinetic and in silico studies

Three series of nucleotide analogues were synthesized and evaluated as potential CD73 inhibitors. Nucleobase replacement consisted in connecting the appropriate aromatic or purine residues through a triazole moiety that is generated from 1,3-dipolar cycloaddition. The first series is related to 4-substituted-1,2,3-triazolo-beta-hydroxyphosphonate ribonucleosides. Additional analogues were also obtained, in which the phosphonate group was replaced by a bisphosphonate pattern (P-C-P-C, series 2) or the ribose moiety was removed leading to acyclic derivatives (series 3). The beta-hydroxyphosphonylphosphonate ribonucleosides (series 2) were found to be potent inhibitors of CD73 using both purified recombinant protein and cell-based assays. Two compounds (2a and 2b) that contained a bis(trifluommethyl)phenyl or a naphthyl substituents proved to be the most potent inhibitors, with IC50 values of 4.8 +/- 0.8 04 mu M and 0.86 +/- 0.2 mu M, compared to the standard AOPCP (IC50 value of 3.8 +/- 0.9 mu M), and were able to reverse the adenosine-mediated immune suppression on human T cells. This series of compounds illustrates a new type of CD73 inhibitors.

Slow Magnetic Relaxation in a [Na2Dy4] Complex and Coexistence of Multiple Metal Rings

Three rare isostructural heterometallic complexes [Na-2{Ln(4)(mu(3)-OH)(2)(ppt)(4)(Hppt)(2)(OAc)(2)}(DMF)(4)] . xH(2)O (H(2)ppt=3-(2-hydroxyphenyl)-5-(pyrazin-2-yl)-1,2,4-triazole, x=2.5, Ln=Dy (1); x=2, Ln=Er (2); x=0, Ln=Yb (3)) have been obtained. The structural analysis displayed that two Na-I and four Ln(III) ions were linked together through N-N groups and O atoms to form a metallmacrocycle with the connectivity pattern [Dy-O-Na-N-N-Dy-O](2). Such cases possess rare hexametallic ring, which further displays one tetrametallic and two trimetallic cyclic units. Magnetic measurements reveal single-molecule magnet (SMM) behavior for 1 with the effective energy barrier of 51.6 K and pre-exponential factor of 6.16×10(-6) s deduced from frequency-dependent magnetic susceptibilities. Ab initio calculations prove that the weak ferromagnetic coupling mainly originats from the dipolar interaction. The transversal magnetic moments in the ground Kramers could suppressed the quantum tunneling of magnetization.

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 693-23-2. SDS of cas: 693-23-2.

Enantioselective Analysis and Degradation Studies of Four Stereoisomers of Difenoconazole in Citrus by Chiral Liquid Chromatography-Tandem Mass Spectrometry

Four difenoconazole stereoisomers were well separated on a Superchiral S-OX column. The absolute configurations of the four stereoisomers of difenoconazole eluted in an orderly fashion with the chiral column were confirmed as (2S,4S), (2S,4R), (2R,4R), and (2R,4S)-difenoconazole, respectively, by single-crystal X-ray diffraction. For the first time, a simple and efficient trace detection method for the determination of residues of the four stereoisomers of difenoconazole in a plant sample by HPLC-MS/MS was developed. The mean recoveries were 78.23-104.38% with RSDs of 0.33-9.95%. The limits of detection for the four difenoconazole enantiomers were 0.0002-0.0004 mg/kg, and the limits of quantitation were 0.0044-0.011 mg/kg in citrus leaves and whole fruits. There was no obvious enantioselectivity upon degradation of the four stereoisomers in citrus leaves and whole fruits in Hunan and Guizhou. In Guangzhou, the rate of degradation of (2R,4R)-difenoconazole was the slowest among the four stereoisomers of difenoconazole.

A Cu-4 cluster-based MOF as a supercapacitor electrode material with ultrahigh capacitance

Developing new pristine metal-organic framework (MOF)-based electrode material for high-performance supercapacitors is a considerable attractive task. Herein, a Cu-4 cluster-based three-dimensional (3D) MOF ([Cu-4(mu(3)-OH)(2)(atrz)(2)(1,3-BDC)(3)]center dot 2H(2)O, Cu-atrz-BDC; atrz, 4-amino-1,2,4-triazole; 1,3-H2BDC, 1,3-benzenedicarboxylic acid) was synthesized and characterized by infrared spectroscopy, X-ray powder diffraction, thermogravimetric analysis, nitrogen adsorption-desorption, scanning electron microscopy, and X-ray photoelectron spectroscopy. The Cu-atrz-BDC firstly was used as an electrode material for supercapacitor. In a three-electrode system, the Cu-atrz-BDC electrode exhibited ultrahigh specific capacitance of 5525 F g(-1) at 1 A g(-1) and its specific capacitance can also keep about 886 F g(-1) after 1000 cycles at 3 A g(-1). Importantly, the Cu-atrz-BDC as the positive electrode and the rGO as the negative electrode were assembled into an asymmetric supercapacitor with excellent cycling stability, displaying the maximum energy density of 9.96 Wh kg(-1) at a power density of 0.81 kW kg(-1). The high supercapacitive performance might be ascribed to its porous three-dimensional structure, the nanosized particles, and better conductivity.
