Electrodeposition of Lithium-Silicon Alloys from 1-butyl-1-methylpyrrolidinium bis(trifluoromethylsulfonyl)amide

The codeposition of lithium and silicon was investigated from 1-butyl-1-methylpyrrolidinium bis(trifluoromethylsulfonyl) amide ([Py-1,Py-4]TFSA)at temperatures >= 100 degrees C. Furthermore, electrodeposition of lithium was studied from the same liquid at >= 100 degrees C. Two different sources of Si(IV) (e.g. either SiCl4 or SiBr4) and LiTFSA as a source for Li+ ions were used. Cyclic voltammetry was employed to study the electrochemical behavior of (SiCl4+LiTFSA)/[Py-1,Py-4]TFSA and (SiBr4+LiTFSA)/[Py-1,Py-4]TFSA. The electrodeposited films were characterized using Scanning Electron Microscopy, X-ray diffraction, and X-ray photoelectron spectroscopy. SiBr4 was found to be suitable to obtain Li-Si alloys from the mentioned IL. Nanocrystalline lithium was obtained with an average grain size of 30 to 40 nm. XRD analysis of the annealed deposits revealed the formation Li-Si alloys. XPS analysis of the deposit obtained from (SiBr4+ LiTFSA)/[Py-1,Py-4]TFSA indicated the presence of fluoride and oxide of lithium besides metallic lithium. (C) 2018 The Electrochemical Society.

Synthesis, crystal structures and thermal properties of six Co(II) and Ni(II) coordination polymers with mixed ligands: Formation of a quadruple-strained helical nanotube

The syntheses, structures and thermal properties of six coordination polymers based on semi-rigid N,N’-bis(3-pyridinyl)terephthalamide (L-1), flexible N,N’-di(3-pyridyl)adipoamide (L-2) and N,N’-di(3-pyridyl) suberoamide (L-3) and auxiliary dicarboxylate ligands, [M(L-1)(AIPA)center dot 2H(2)O](n), (M= Ni, 1; Co, 2; H(2)AIPA = 5-acetamido isophthalic acid), [Ni(L-2)(AIPA)(H2O)(2)](n), 3, [Co(L-2)(0.5)(AIPA)(H2O)](n), 4, [Co(L-3)(2,4PDC)(H2O)](n) (2,4-H2PDC = 2.4-pyridinedicarboxylic acid), 5, and [Co(L-3)(5-Br-IPA)(H2O)](n) (5Br H(2)IPA = 5-bromoisophthalic acid), 6, are reported, which have been structurally characterized by X-ray crystallography. Complexes 1 and 2 are isomorphous, forming 3D nets with the new (4.6.8)(4.6(4).8(5)) topology, which can be further simplified as self-catenated networks with the (4(24).6(4))812 topology, while 3 is a 1D looped chain and 4 and 6 show 2D layers with the (4(2).6(3).8)(4(2).6)-3,4L83 and (4(4).6(2))-sql topologies, respectively. Moreover, complex 5 shows quadruple-strained helices formed by cobalt ions and L-3 ligands, which are supported by 2,4-PDC2- anions to construct the rare single walled metal-organic nanotubes that are supported by extensive N-H–O and O-H–O hydrogen bonds. The roles of ligand flexibility and the identity of the metal ion in the formation of 1-6 as well as their thermal properties are discussed. (C) 2018 Elsevier B.V. All rights reserved.

Insight into nucleophilic fragmentation mechanisms by glutamic acid side chain in singly protonated glutathione and related peptidyl ions

Fragmentation mechanisms of the singly protonated glutathione (gamma-ECG) and its synthetic analogue peptides (ECG and PPECG) have been investigated by liquid chromatography tandem-mass spectrometry and theoretical calculations. In the mass spectra, similar fragmentation patterns were observed for gamma-ECG and ECG, but a completely different one was found in the case of PPECG. The E-C amide bond cleavage is the predominant pathway for the fragmentation of gamma-ECG and ECG, whereas the additional N-terminal prolyl residues in PPECG significantly suppress the E-C amide bond cleavage. Theoretical calculations reveal that the fragmentation efficiencies of the E-C bonds in the protonated gamma-ECG and ECG are much higher than that in the protonated PPECG, being attributed to their lower barriers of the potential energy; clearly the introduction of two prolyl residues can increase substantially the potential energy barrier. In the proposed mechanism, the protonated E-C amide bonds in the three peptides are first weakened followed by a nucleophilic addition by the glutamyl carboxyl oxygen atom in side chain, leading to the breaking of the E-C amide bonds. However, the processes of E-C bond fragmentation for three protonated analogs were not collaborative. Protonated amide bonds first fragment, then the nucleophilic addition by the side chain of glutamyl carboxyl oxygen atom takes places. On the other hand, the prolyl residues in PPECG can largely diminish the nucleophilic addition, resulting in a much lower efficiency of its E-C amide bond breaking. Distance analysis indicates that breaking the E-C amide bonds in the protonated gamma-ECG, ECG, and PPECG ions could not occur without the assistance from the nucleophilic attack, highlighting an asynchronous collaborative process in the bond breakings.

The Potential of Alkyl Amides as Novel Biomarkers and Their Application to Paleocultural Deposits in China

A series of alkyl amides was detected and identified in the sedimentary record from an archaeological site at Yuchisi, Mengcheng, Anhui, China. The alkyl amides profiles change abruptly at the depth corresponding to the transition between two prehistoric cultures, which also corresponds to an abrupt change in the fatty acid ratio C-18:2/C-18:0. The different patterns of variation of the longer and shorter chain alkyl amides at the depth of the cultural transition may reflect differences in their response to external environmental changes, as well as different sources. This is the first study of the stratigraphic variation of alkyl amides in sediments, and their first application to assess paleoenvironmental changes. We suggest that alkyl amides may have potential as new biomarkers in archeological and paleoenvironmental studies.

Site-selective C-H bond carbonylation with CO2 and cobalt-catalysis

Utilization of anthropogenic greenhouse gas CO2 for catalytic C-C bond formation via conversion to essentially valuable C1 synthons like CO is very challenging. The requirement of an efficient catalyst that has the ability to convert CO2 into CO and activate inert C-H bonds is the bottleneck. We herein demonstrate a tandem approach accomplished in a two-chamber system for efficient fluoride-mediated generation of CO from CO2 using disilane as a deoxygenating reagent and utilization of the in situ-produced CO gas for C-H bond carbonylation using earth-abundant cobalt catalysts. The ease of handling CO2 gas at atmospheric pressure allows us to prepare C-13 labelled compounds which are otherwise difficult to achieve. The procedure developed makes it possible to utilize CO2 as a CO source, which can be widely applied as a C1 synthon that can be incorporated between C-H and N-H bonds of aromatic, hetero-aromatic and aliphatic carboxamides for the synthesis of various cyclic imides including spirocycles in a site-selective fashion. The late-stage derivatization of a well-known angiotensin receptor blocker (ARB), Telmisartan, and a well-known drug for very low-density lipoproteins (VLDLs), Gemfibrozil, is demonstrated. Further, to showcase the generality of the reaction, various pharmacologically important and privileged scaffolds like xanthone, coumarin and isatin have been synthesized with CO2 under atmospheric pressure.

Glucagon-related peptides from phylogenetically ancient fish reveal new approaches to the development of dual GCGR and GLP1R agonists for type 2 diabetes therapy

The insulinotropic and antihyperglycaemic properties of glucagons from the sea lamprey (Petromyzontiformes), paddlefish (Acipenseriformes) and trout (Teleostei) and oxyntomodulin from dogfish (Elasmobranchii) and ratfish (Holocephali) were compared with those of human glucagon and GLP-1 in mammalian test systems. All fish peptides produced concentration-dependent stimulation of insulin release from BRIN-BD11 rat and 1.1 B4 human clonal beta-cells and isolated mouse islets. Paddlefish glucagon was the most potent and effective peptide. The insulinotropic activity of paddlefish glucagon was significantly (P < 0.01) decreased after incubating BRIN-BD11 cells with the GLP1R antagonist, exendin-4(9-39) and the GCGR antagonist [des-His(1),Pro(4), Glu(9)] glucagon amide but GIPR antagonist, GIP(6-30)Cex-K-40[palmitate] was without effect. Paddlefish and lamprey glucagons and dogfish oxyntomodulin (10 nmol L-1) produced significant (P < 0.01) increases in cAMP concentration in Chinese hamster lung (CHL) cells transfected with GLP1R and human embryonic kidney (HEK293) cells transfected with GCGR. The insulinotropic activity of paddlefish glucagon was attenuated in CRISPR/Cas9-engineered GLP1R knock-out INS-1 cells but not in GIPR knock-out cells. Intraperitoneal administration of all fish peptides, except ratfish oxyntomodulin, to mice together with a glucose load produced significant (P < 0.05) decreases in plasma glucose concentrations and paddlefish glucagon produced a greater release of insulin compared with GLP-1. Paddlefish glucagon shares the sequences Glu(15)-Glu(16) and Glu(24)-Trp(25)-Leu(26)-Lys(27)-Asn(28)-Gly(29) with the potent GLP1R agonist, exendin-4 so may be regarded as a naturally occurring, dual-agonist hybrid peptide that may serve as a template design of new drugs for type 2 diabetes therapy.

Fish gelatin films incorporated with different oils: effect of thickness on physical and mechanical properties

Properties of fish gelatin films incorporated with different oils at different thickness investigated. Gelatin films incorporated with all oils resulted in higher elongation at break (EAB) compared to control film, regardless of the oils type (P <= 0.05). Increasing the thickness of gelatin films with oils decreased the solubility value (P <= 0.05) significantly. However, water vapor permeability (WVP) of gelatin films containing oils increased as the thickness of films increased. FTIR spectra showed that incorporation of different oils into gelatin films gave effect on the molecular organization and intermolecular interaction in films matrix particularly at the wavenumber of Amide-I band and 1739-1744 cm(-1). SEM analysis revealed the addition of oils into gelatin films enhanced the roughness of the film surface and cross-section. An appropriate combination of oils at moderate thickness could improve the mechanical and barrier properties of fish gelatin films thus fulfill the application either as coatings or films.

Mapping tumour heterogeneity with pulsed 3D CEST MRI in non-enhancing glioma at 3 T

Objective Amide proton transfer (APT) weighted chemical exchange saturation transfer (CEST) imaging is increasingly used to investigate high-grade, enhancing brain tumours. Non-enhancing glioma is currently less studied, but shows heterogeneous pathophysiology with subtypes having equally poor prognosis as enhancing glioma. Here, we investigate the use of CEST MRI to best differentiate non-enhancing glioma from healthy tissue and image tumour heterogeneity. Materials & Methods A 3D pulsed CEST sequence was applied at 3 Tesla with whole tumour coverage and 31 off-resonance frequencies (+6 to -6 ppm) in 18 patients with non-enhancing glioma. Magnetisation transfer ratio asymmetry (MTRasym) and Lorentzian difference (LD) maps at 3.5 ppm were compared for differentiation of tumour versus normal appearing white matter. Heterogeneity was mapped by calculating volume percentages of the tumour showing hyperintense APT-weighted signal. Results LDamide gave greater effect sizes than MTRasym to differentiate non-enhancing glioma from normal appearing white matter. On average, 17.9 % +/- 13.3 % (min-max: 2.4 %-54.5 %) of the tumour volume showed hyperintense LDamide in non-enhancing glioma. Conclusion This works illustrates the need for whole tumour coverage to investigate heterogeneity in increased APT-weighted CEST signal in non-enhancing glioma. Future work should investigate whether targeting hyperintense LDamide regions for biopsies improves diagnosis of non-enhancing glioma.
