Improved spinnability of PA 6 solutions using AC electrospinning

The experiment addressed the alternating current (AC) electrospinning of polyamide 6 (PA 6) solutions composed of organic acids, which are commonly employed in direct current (DC) electrospinning systems. Initial testing revealed that it is not possible to AC spin ordinary PA 6 solutions so as to provide a product that can be used in subsequent material experiments. The solutions were enriched with oxoacids, which led to the improvement of the spinning process. The solutions were tested by means of both a viscometer and conductivity meter. The layers so produced were scanned using a SEM microscope. Each of the materials was analyzed for the purpose of the provision of statistical data. (C) 2020 Elsevier B.V. All rights reserved.

Ruthenium(IV) Intermediates in C-H Activation/Annulation by Weak O-Coordination

Ruthenium(IV) complexes were identified as key intermediates of C-H/O-H activations by weak O-coordination. Thus, the annulations of sulfoxonium ylides by benzoic acids provided expedient access to diversely-decorated isocoumarins with ample scope. Detailed experimental and computational studies provided strong support for a facile BIES-C-H activation, along with cyclometalated ruthenium(IV) intermediates within a versatile ruthenium(II/IV) catalysis regime (BIES=base-assisted internal electrophilic substitution).

Quantum mechanical calculations of different monomeric structures with the same electroactive group to clarify the relationship between structure and ultimate optical and electrochemical properties of their conjugated polymers

Quantum mechanical calculations can clarify the relationship between structure and ultimate optical and electrochemical properties of conjugated polymers and produce a ground for the design of advanced materials for futuristic applications. Herein, we have examined the structural geometries and electronic properties of different monomeric structures with the same electmactive group to provide a relationship between calculated electronic properties of the monomers with the observed optical and electrical properties of their conjugated polymers. For this purpose, three different amide substituted 2,5-di(2-thienyl)-1H-pyrrole compounds containing a different number of electroactive groups have been synthesized and molecular structure optimizations have been carried out with the Density Functional Theory (DFT) calculations. FT-IR and NMR spectra of optimized geometries have been compared with experimental data. Furthermore, electronic properties of the monomeric structures such as chemical hardness/softness, ionization potential, HOMO-LUMO energy levels, electronegativity have been revealed and molecular electrostatic potential (MEP) surface has been calculated to determine the electrophilic and nucleophilic reactive attack regions of the molecules considered in this study. Finally, Total Density of State (TDOS), Partial Density of State (PDOS) and Mulliken charge analyses of these molecules have been carried out. Our calculations based on ab-initio methods for the monomers have been compared with the optical and electrical properties of their conductive polymers in order to understand interrelationship between monomer structure and polymer properties.

Clarifying the dehydrogenation pathway of catalysed Li-4(NH2)(3)BH4-LiH composites

The effect of different metal oxides (Co3O4 and NiO) on the dehydrogenation reaction pathways of the Li-4(NH2)(3)BH4-LiH composite was investigated. The additives were reduced to metallic species i.e. Co and Ni which act as catalysts by breaking the B-H bonds in the Li-B-N-H compounds. The onset decomposition temperature was lowered by 32 degrees C for the Ni-catalysed sample, which released 8.8 wt% hydrogen below 275 degrees C. It was demonstrated that the decomposition of the doped composite followed a mechanism via LiNH2 and Li3BN2 formation as the end product with a strong reduction of NH3 emission. The sample could be partially re-hydrogenated (similar to 1.5 wt%) due to lithium imide/amide transformation. To understand the role of LiH, Li-4(NH2)(3)BH4-LiH-NiO and Li-4(NH2)(3)BH4-NiO composites were compared. The absence of LiH as a reactant forced the system to follow another path, which involved the formation of an intermediate phase of composition Li3BN2H2 at the early stages of dehydrogenation and the end products LiNH2 and monoclinic Li3BN2. We provided evidence for the interaction between NiO and LiNH2 during heating and proposed that the presence of Li facilitates a NHx-rich environment and the Ni catalyst mediates the electron transfer to promote NHx coupling.

SAR by (Protein-Observed) F-19 NMR

CONSPECTUS: Inhibitor discovery for protein-protein interactions has proven difficult due to the large protein surface areas and dynamic interfaces involved. This is particularly the case when targeting transcription-factor-protein interactions. To address this challenge, structural biology approaches for ligand discovery using X-ray crystallography, mass spectrometry, and nuclear magnetic resonance (NMR) spectroscopy have had a significant impact on advancing small molecule inhibitors into the clinic, including the U.S. Food and Drug Administration approved drug, Venetoclax. Inspired by the protein-observed NMR approach using H-1-N-15-HSQC NMR which detects chemical shift perturbations of 15N-labeled amides, we have applied a complementary protein-observed F-19 NMR approach using F-19-labeled side-chains that are enriched at protein-protein-interaction interfaces. This protein-observed F-19 NMR assay is abbreviated PrOF NMR to distinguish the experiment from the more commonly employed ligand-observed F-19 NMR methods. In this Account, we describe our efforts using PrOF NMR as a ligand discovery tool, particularly for fragment-based ligand discovery (FBLD). We metabolically label the aromatic amino acids on proteins due to the enrichment of aromatic residues at protein interfaces. We choose the F-19 nucleus due to its high signal sensitivity and the hyperresponsiveness of F-19 to changes in chemical environment. Simultaneous labeling with two different types of fluorinated aromatic amino acids for PrOF NMR has also been achieved. We first describe the technical aspects of considering the application of PrOF NMR for characterizing native protein-protein interactions and for ligand screening. Several test cases are further described with a focus on a transcription factor coactivator interaction with the KIX domain of CBP/p300 and two epigenetic regulatory domains, the bromodomains of BRD4 and BPTF. Through these case studies, we highlight medicinal chemistry applications in FBLD, selectivity screens, structure-activity relationship (SAR) studies, and ligand deconstruction approaches. These studies have led to the discovery of some of the first inhibitors for BPTF and a novel inhibitor class for the N-terminal bromodomain of BRD4. The speed, ease of interpretation, and relatively low concentration of protein needed for NMR-based binding experiments affords a rapid, structural biology-based method to discover and characterize both native and new ligands for bromodomains, and it may find utility in the study of additional epigenetic proteins and transcription-factor-protein interactions.

Synthesis of mitochondria-targeted coumarin-3-carboxamide fluorescent derivatives: Inhibiting mitochondrial TrxR2 and cell proliferation on breast cancer cells

Targeting specific mitochondrial alterations to kill cancer cells without affecting their normal counterparts emerges as a feasible strategy. Coumarin derivatives have demonstrated the potential anti-breast cancer activities. By coupling coumarin-3-carboxamide derivatives with mitochondria carrier triphenylphosphonium, mitocoumarins 15a-c were produced and tested as the anti-breast cancer fluorescence agents. Among them, 15b as the amide-based drug potently suppressed the cell growth in MCF-7, MDA-231, SK-BR-3 breast cancer cells with the IC50 values from 3.0 to 4.1 mu M, including the lower cytotoxicity to normal MCF-10A cells with the IC50 value around 45.30 +/- 2.45 mu M. In mechanistic study for 15b in MDA-MB-231 cells, it could localize in mitochondria to elicit ROS burst and collapse Delta psi(m). Besides, it could deplete GSH by an irreversible alkylation process and moderately inhibit mitochondrial thioredoxin reductase TrxR2, thus leading to aggravate cellular oxidative stress. This study reported 15b might be useful for the further development into a mitochondria-targeted anti triple negative breast cancer drug.

Synthesis of benzamides through direct condensation of carboxylic acids and amines in the presence of diatomite earth@IL/ZrCl4 under ultrasonic irradiation

A green, rapid, mild and highly efficient pathway for the preparation of benzamide derivatives is reported. The reaction was performed through direct condensation of benzoic acids and amines under ultrasonic irradiation in the presence of Lewis acidic ionic liquid immobilized on diatomite earth (diatomite earth@IL/ZrCl4). A new, highly efficient and green solid acid catalyst was easily prepared via a two-step procedure and used as an effective reusable catalyst. The prepared catalyst provides active sites for the synthesis of benzamides. The advantages of this method are the use of a superior and recoverable catalyst, low reaction times, simple procedure, high-yielding and eco-friendly process and use of ultrasonic irradiation as a green and powerful technology. Since benzamides are used widely in the pharmaceutical, paper and plastic industries, and also as an intermediate product in the synthesis of therapeutic agents, the presented new synthetic methods for this type of compounds can be of considerable importance.

Electrochemical Cobalt-Catalyzed C-H Activation

Carbon-heteroatom bonds represent omnipresent structural motifs of the vast majority of functionalized materials and bioactive compounds. C-H activation has emerged as arguably the most efficient strategy to construct C-Het bonds. Despite of major advances, these C-H transformations were largely dominated by precious transition metal catalysts, in combination with stoichiometric, toxic metal oxidants. Herein, we discuss the recent evolution of cobalt-catalyzed C-H activations that enable C-Het formations with electricity as the sole sustainable oxidant until May 2018.

Synthesis, characterization, and evaluation of antioxidant and antibacterial activities of novel indole-hydrazono thiazolidinones

Three-component reactions of oxindole derivatives, thiosemicarbazide with dialkyl acetylenedicarboxylate (or maleimide) led to novel indole-hydrazono thiazolidinones in high-to-excellent yields. The antioxidant activities of the synthesized compounds were studied by 1,1-diphenyl-2-picrylhydrazyl radical scavenging assay. Among the products, those with amide moiety exhibited better antioxidant activities than other ester derivatives of indole-hydrazono thiazolidinones. Minimum bactericidal concentration (MBC) was evaluated against Gram-positive bacteria (Staphylococcus aureus and Bacillus subtilis) and Gram-negative bacteria (Escherichia coli and Pseudomonas aeruginosa) at different concentrations. However, the MBC values for compounds with amide group in their skeleton exhibited higher antibacterial activity than compounds with ester group. Therefore, it is assumed that these compounds could be used as effective antioxidant and antibacterial agents. [GRAPHICS]
