Free-Standing Ion-Conductive Gels Based on Polymerizable Imidazolium Ionic Liquids

A free-standing ion-conductive gel is formed by spontaneous self-assembly of the amphiphilic ionic liquid 1-tetradecyl-3-methylimidazolium chloride (C-14 MIm center dot Cl) and the cross-linkable monomer 6-hexanediol diacrylate (HDODA) in a mixed solvent of 1-octene, 1-butanol, and water. The ionic conductivity of this ion gel is 24 mS cm(-1) at 33 degrees C. To enhance the mechanical strength of the ion gels, the acrylate ionic liquid 1-(2-acryloyloxyundecy1)-3-methylimidazolium bromide (A-C-11 MIm center dot Br) was added, leading to significant morphological changes of the HDODA phase from spherical, ellipsoid, angular platelets to interconnected with increasing addition of the acrylate ionic liquid and consequent enhancement in the mechanical strength of the resulting ion gels. Small angle X-ray scattering data reveal that the ion gels are composed of bicontinuous phase. The formation of the anisotropic HDODA structures upon introduction of the acrylate ionic liquid was accompanied by a change of the bicontinuous phase to be undulated, which increased the ionic path through the formed film, resulting in reduced ionic conductivity. Such coaxial structured gels may be a promising route for developing highly ion-conductive as well as mechanically stable solid electrolyte systems.

Synthesis of Enantiomerically Enriched Alkynylaryl-Substituted alpha-Amino Acids through Sonogashira Reactions

Various enantiomerically enriched non-proteinogenic (S)-alpha-amino acids were obtained in high chemical and optical yields through Sonogashira cross-coupling reactions and Glaser couplings. The Schiff base Ni(II)complexes of the chiral auxiliary (S)-BPB (BPB = N-benzyl proline benzophenone) and an amino acid containing an aryl bromide moiety in the alpha-position were synthesized and subsequently used in Sonogashira coupling reactions. The obtained Ni(II) complexes were hydrolyzed with aqueous HCl and novel amino acids, containing an alkynylaryl moiety, were isolated in good yields and with high enantiomeric excess (>99% ee). The chiral auxiliary (S)-BPB can be recycled and reused for the synthesis of the starting Ni(II) complex.

Structural variations in (001)-oriented layered lead halide perovskites, templated by 1,2,4-triazolium

A new hybrid lead(ii) halide perovskite, (TzH)(2)PbCl4, ([TzH(+)] = 1,2,4-triazolium), adopts a (001)-oriented layered perovskite structure, which can be considered as derived from the n = 1 Ruddlesden-Popper (RP) type. Variable temperature single crystal X-ray diffraction reveals a structural phase transition in the region 125 K < T < 173 K between a high temperature, high symmetry polymorph, space group Cmcm, and a low temperature, low symmetry chiral polymorph, space group P2(1)2(1)2(1), which has a tripled unit cell volume. UV-Vis spectra suggest a band gap of 3.30 eV for (TzH)(2)PbCl4. A second polymorph of the bromide analogue, (TzH)(2)PbBr4-II, is also reported, and structural relationships between all three variants are discussed. 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 98475-07-1.

Therapeutic efficacy and immunoregulatory effect of Qiangji Jianli Capsule for patients with myasthenia gravis Study protocol for a series of randomized, controlled N-of-1 trials

Introduction: Myasthenia gravis (MG) is an autoimmune disease in which antibodies directly target components of the neuromuscular junction, causing neuromuscular conduction damage that leads to muscle weakness. The current pharmaceutical treatment for MG is still not ideal to address the problems of disease progression, high recurrence rate, and drug side effects. Clinical observations suggest that traditional Chinese medicine (TCM) can strengthen immunity and improve symptoms of MG patients, delay the progression of the disease, reduce or even prevent the need for immunosuppressive therapy when used in combination with acetylcholinesterase inhibitors or low-dose prednisone, as well as improve the quality of life of patients. The Qiangji Jianli Capsule (QJC) is a combination of medicinal herbs which is used in traditional Chinese medicine. Since MG is a rare disorder, randomized controlled trials comparing large cohorts are difficult to conduct. Therefore, we proposed to aggregate data from a small series of N-of-1 trials to assess the effect of the Chinese medical prescription QJC, which strengthens the spleen and nourishes Qi, as an add-on treatment for MG with spleen and stomach Qi deficiency syndrome. Methods and analysis: Single-center, randomized, double-blind, multiple crossover N-of-1 studies will compare QJC versus placebo in 5 adult MG patients with spleen and stomach Qi deficiency syndrome. Patients will undergo 3 cycles of two 4-week intervention periods. According to the treatment schedule, patients will continue to be treated with pyridine bromide tablets, prednisone acetate, tablets and/or tacrolimus capsules throughout the entire trial. Each period consisting of 4-week oral add-on treatment with QJC will be compared with 4-week add-on treatment with a placebo. The primary endpoints are quantitative myasthenia gravis (QMG) test; measurement of the amount of T-reg cells and cytokines such as interferon-gamma (IFN-gamma), interleukin-4 (IL-4), interleukin-17A (IL-17A), and transforming growth factor-beta (TGF-beta); and corticosteroid or immunosuppressive agent dosage. Secondary outcome measures: Clinical: Evaluation of the effect of TCM syndromes; MG-activities of daily living (MG-ADL) scales; adverse events. Ethics and dissemination: This study was approved by The First Affiliated Hospital of Guangzhou University of Chinese Medicine (GZUCM), No. ZYYECK[2019]038. The results will be published in a peer-reviewed publication. Regulatory stakeholders will comment on the suitability of the trial for market authorization and reimbursement purposes.

Discovery of novel indolyl-1,2,4-triazole hybrids as potent vascular endothelial growth factor receptor-2 (VEGFR-2) inhibitors with potential anti-renal cancer activity

Targeting VEGFR-2 signaling pathway is well-established as an important approach for the treatment of solid tumors, particularly renal cancer. Herein, novel indolyl-1,2,4-triazole hybrids were designed and synthesized as VEGFR-2 kinase inhibitors with potential anti-renal cancer activity. The structures of the newly synthesized compounds were confirmed based on their spectral and elemental analyses. The results of in vitro kinase assay indicated that all target compounds revealed submicromolar inhibition of VEGFR-2 kinase enzyme. Analogs 5c, 5d and 9b emerged as the most active compounds (IC50 = 0.034-0.064 mu M), showing VEGFR-2 inhibitory activity much superior to that of sunitinib reference drug (IC50 = 0.075 mu M). Moreover, compounds 5a, 8c, 9d, 12c were equipotent to sunitinib against VEGFR-2 kinase. Additionally, the most potent compounds were further examined for their anticancer activity against two human renal cancer cell lines. All screened compounds effectively inhibited the growth of the two tested cell lines with IC50 values spanning from sub-micromolar to low micromolar levels. Compounds 5b, 5d, 11c and 12c were three to five-fold more potent than sunitinib against CAKI-1 cell line. Analogue 8c was superior/comparable to sunitinib against CAKI-1/A498 cell lines. Moreover, compound 9d showed double potency of sunitinib against A498 cell line. Besides, compounds 8c and 12c demonstrated a safety profile much better than that of sunitinib against non-cancer human renal cells. As well, the docked models of title compounds revealed strong interactions with key residues within the active site of VEGFR-2 kinase.

Electrodeposition of Nickel/Graphene Oxide Particle Composite Coatings: Effect of Surfactants on Graphene Oxide Dispersion and Coating Performance

The dispersibility of graphene oxide particles (GOs) in nickel electrolytes is critical for its uniform incorporation in the nickel matrix during the electrodeposition process. In this study, we study the fundamental interaction of surfactants and nickel ionic strength for uniform and stable incorporation of GOs in nickel electrolytes and their effect on coating performance. The results indicate that the non-ionic surfactant Polyethylene glycol (PEG) has the optimal dispersibility of GOs in nickel electrolyte, followed by the cationic surfactant Cetyltrimethylammonium bromide (CTAB) and the anionic surfactant Sodium dodecyl sulfate (SDS). It is also noted that the increasing nickel ionic strength would deteriorate the stability of GOs, attributing to the generation of cross-linking of high strength divalent nickel ions with dispersed graphene oxide. The electrodeposited coatings show that more incorporation of graphene oxide in the coating is achieved when the PEG surfactant is used, which leads to an increased hardness by 146% and a decreased friction coefficient by 72.7% under low nickel sulfamate concentration (200 g l(-1)), compared to pure nickel coating. Eventually, the study shows that higher nickel ionic strength would deteriorate the performance of the coatings, while the selection of proper surfactant can compensate for it.

Synthesis of benzotriazoles derivatives and their dual potential as alpha-amylase and alpha-glucosidase inhibitors in vitro: Structure-activity relationship, molecular docking, and kinetic studies

Benzotriazoles (4-6) were synthesized which were further reacted with different substituted benzoic acids and phenacyl bromides to synthesize benzotriazole derivatives (7-40). The synthetic compounds (7-40) were characterized via different spectroscopic techniques including EI-MS, HREI-MS, H-1-, and C-13 NMR. These molecules were examined for their anti-hyperglycemic potential hence were evaluated for alpha-glucosidase and alpha-amylase inhibitory activities. All benzotriazoles displayed moderate to good inhibitory activity in the range of IC50 values of 2.00-5.6 and 2.04-5.72 mu M against alpha-glucosidase and alpha-amylase enzymes, respectively. The synthetic compounds were divided into two categories A and B, in order to understand the structure-activity relationship. Compounds 25 (IC50 = 2.41 +/- 131 mu M), (IC50 = 2.5 +/- 1.21 mu M), 36 (IC50= 2.12 +/- 1.35 M), (IC50 = 2.21 +/- 1.08 mu M), and 37 (IC50 = 2.00 +/- 1.22 mu M), (IC50 = 2.04 +/- 1.4 mu M) with chloro substitution/s at aryl ring were found to be most active against alpha-glucosidase and alpha-amylase enzymes. Molecular docking studies on all compounds were performed which revealed that chloro substitutions are playing a pivotal role in the binding interactions. The enzyme inhibition mode was also studied and the kinetic studies revealed that the synthetic molecules have shown competitive mode of inhibition against alpha-amylase and non-competitive mode of inhibition against alpha-glucosidase enzyme.

Alloy CsCdxPb1-xBr3 Perovskite Nanocrystals: The Role of Surface Passivation in Preserving Composition and Blue Emission

Various strategies have been proposed to engineer the band gap of metal halide perovskite nanocrystals (NCs) while preserving their structure and composition and thus ensuring spectral stability of the emission color. An aspect that has only been marginally investigated is how the type of surface passivation influences the structural/color stability of AMX(3) perovskite NCs composed of two different M2+ cations. Here, we report the synthesis of blue-emitting Cs-oleate capped CsCdxPb1-xBr3 NCs, which exhibit a cubic perovskite phase containing Cd-rich domains of Ruddlesden-Popper phases (RP phases). The RP domains spontaneously transform into pure orthorhombic perovskite ones upon NC aging, and the emission color of the NCs shifts from blue to green over days. On the other hand, postsynthesis ligand exchange with various Cs-carboxylate or ammonium bromide salts, right after NC synthesis, provides monocrystalline NCs with cubic phase, highlighting the metastability of RP domains. When NCs are treated with Cs-carboxylates (including Cs-oleate), most of the Cd2+ ions are expelled from NCs upon aging, and the NCs phase evolves from cubic to orthorhombic and their emission color changes from blue to green. Instead, when NCs are coated with ammonium bromides, the loss of Cd2+ ions is suppressed and the NCs tend to retain their blue emission (both in colloidal dispersions and in electroluminescent devices), as well as their cubic phase, over time. The improved compositional and structural stability in the latter cases is ascribed to the saturation of surface vacancies, which may act as channels for the expulsion of Cd2+ ions from NCs.

Lasing from reduced dimensional perovskite microplatelets: Fabry-Perot or whispering-gallery-mode?

Cesium lead bromide (CsPbBr3) perovskite has attracted great attention recently for its potentials for next-generation green-color lasing devices owing to the relatively high structural stability and the high emission efficiency among the perovskite family. Herein, we explore the origins of cavity modes in CsPbBr3 microplatelets (MPs) lasers by using angle-resolved microphotoluminescence Fourier imaging technique, which is still controversial so far. In-plane Fabry-Perot (F-P) mode lasing transition to whispering-gallery-mode (WGM) lasing is verified at room temperature, which mostly occurs in large MPs with edge length (L) over 13 mu m. The F-P lasing is suppressed upon decreasing L or increasing excitation density, and the WGM lasing is predominant for all MPs at high excitation density. Furthermore, the parity and symmetry of in-plane F-P modes are classified. These results advance the fundamental understanding of lasing modes in planar microcavities as well as their applications in on-chip interconnection and quantum optics.

Investigation of poly(CTAB-MWCNTs) composite based electrochemical DNA biosensor and interaction study with anticancer drug Irinotecan

Development of sensitive, rapid and low-cost DNA detection tools and elucidation of the structural changes of DNA after interaction with chemotherapeutic drugs is of great significance. In this respect, the objective of this work was to construct a DNA biosensor based on electrodeposited cetyl trimethylammonium bromide-multiwalled carbon nanotubes (poly(CTAB-MWCNTs)) composite on single-use graphite electrodes (PGEs) for the direct detection of dsDNA and further implementation for the anticancer drug screening. The morphology and electrochemical characterization of the fabricated biosensor were utilized. The new surfactant-carbon nanotubes based electrode with porous composite structure led to significant improvement for the detection of dsDNA in the linear range of 4-150 mu g mL(-1) with detection limit of (LOD) 3.06 mu g mL(-1). Under the optimized conditions, the dsDNA modified poly(CTAB-MWCNTs)/PGEs were utilized to evaluate the binding interaction of an anticancer drug, irinotecan (CPT-11) with DNA by differential pulse voltammetry (DPV) and also by UV-vis spectroscopy. The guanine oxidation signal was linear in a CPT-11 concentration range of 2-500 mu g mL(-1) with LOD of 1.03 mu g mL(-1). Moreover, equilibrium constant (K) for the binding process was determined as 6.84 x 10(4 )M(-1). The applicability of the procedure was examined by quantitative measuring of CPT-11 in serum samples with high recoveries (106.0-98.2%). The proposed DNA biosensor hold considerable promise for different biointeraction applications.
