Accurate measurement of effective Li-Li scalar coupling constants: the NMR missing link for alkyllithium aggregates

Scalar coupling in organolithium systems can provide access to useful structural and dynamic informations. In this work, we propose a robust method for the accurate measurement of the effective (2)J(Li-Li) coupling constant in tetramerics alkyllithium aggregates. This crucial information, unavalaible to date, gives a simple access to various structural factors, including the dynamics, solvation and the operative steric hindrance of alkyl chains.

Surfactant-modified natural zeolites as carriers for diclofenac sodium release: A preliminary feasibility study for pharmaceutical applications

This research aimed to investigate the feasibility of using cetyltrimethylammonium bromide-modified natural zeolites (clinoptilolite and chabazite) as carriers for diclofenac sodium release. The surfactant-modified natural zeolites were characterized by X-ray fluorescence, X-ray powder diffraction, scanning electron microscopy, thermogravimetric analysis, differential thermogravimetric analysis, and Brunauer-Emmett-Teller surface area analysis. On the other hand, drug adsorption and in vitro release kinetics in simulated intestinal fluid were also investigated to assess the potential pharmaceutical applications of clinoptilolite and chabazite. Results showed that the higher the surfactant concentration, the greater the adsorption capacity of the surface-modified natural zeolites due to the formation of bilayers on their surface. Diclofenac sodium adsorption tests on natural zeolites showed that the adsorption capacity was lower in the natural zeolites than in the surfactant-modified natural zeolites, which indicates that the modification with the surfactant enhanced diclofenac sodium release. The surfactant-modified chabazite showed a very rapid 100% release of diclofenac sodium after 3 h, so it is not suitable for prolonged release, whereas the surfactant-modified clinoptilolite showed a rapid initial release, but maintained a gradual release, being suitable for prolonged release since after 6 h a 100% released of diclofenac sodium was not achieved. The surfactant-modified clinoptilolite is more efficient than the surfactant-modified chabazite as a carrier for diclofenac sodium.

Structural characterisation of new ionic liquids via X-ray crystallography

Ionic liquids (ILs) have many advantageous properties exploited in an increasing number of applications. Crucial to their continued and expanded use is the fine-tuning of IL structures to refine their capability profiles. Organic chemistry can play an important role in providing ILs with more sophisticated properties. In this communication, we provide relevant examples of the use of organic chemistry in the planning and delivery of novel structures and improved capabilities. Here we present three novel ILs characterized by X-ray crystallography resulting from partnering known anions, tetralluoroborate (BF4-), bis (trifluoromethane) sulfonimide (TFSI-), and bromide (Br-) with novel cations based on three main structural types. The crystallographic analyses reported here high-light intermolecular and suprarnolecular features particularly the role of van der Waals interactions. (C) 2020 Elsevier B.V. All rights reserved.

White-light emission system based on cyclodextrin/surfactant supramolecular assembly

A multiple luminescence colors system was facile constructed based on the supramolecular assembly of anionic (3-cyclodextrin, dodecayltrimethylaminium bromide (DTAB), a naphthalimide dye (G(1)) and a benzothiadiazole derivative (G(2)). Significantly, the fabricated system exhibited highly efficient energy transfer from G(1) to G(2), accompanying by fluorescence color change from blue to yellow, including white light. Furthermore, the white light emission supramolecular assembly was constructed from anionic cyclodextrin with low degree of substitution and DTAB exhibited reversible temperature responsiveness with fluorescent color changes from white to yellow.

Effect of Sepatronium Bromide (YM-155) on DNA Double-Strand Breaks Repair in Cancer Cells

Survivin, as an antiapoptotic protein often overexpressed in cancer cells, is a logical target for potential cancer treatment. By overexpressing survivin, cancer cells can avoid apoptotic cell death and often become resistant to treatments, representing a significant obstacle in modern oncology. A survivin suppressor, an imidazolium-based compound known as YM-155, is nowadays studied as an attractive anticancer agent. Although survivin suppression by YM-155 is evident, researchers started to report that YM-155 is also an inducer of DNA damage introducing yet another anticancer mechanism of this drug. Moreover, the concentrations of YM-155 for DNA damage induction seems to be far lower than those needed for survivin inhibition. Understanding the molecular mechanism of action of YM-155 is of vital importance for modern personalized medicine involving the selection of responsive patients and possible treatment combinations. This review focuses mainly on the documented effects of YM-155 on DNA damage signaling pathways. It summarizes up to date literature, and it outlines the molecular mechanism of YM-155 action in the context of the DNA damage field.

Effective Tools for the Metal-catalyzed Regiodivergent Direct Arylations of (Hetero)arenes

The direct functionalization of two different C-H bonds of the same organic molecule using different procedures – also called regiodivergent C-H bond functionalization – currently represents an important research topic in organic chemistry, as it demonstrates the versatility of C-H bond functionalization methodology. Over the last decade, the number of tools to control such regiodivergent C-H bond functionalizations has increased significantly. In this account, we will present the various tools that allowed us to arylate different positions of various (hetero)arenes, via a C-H bond functionalization, using palladium or ruthenium catalysis.

Simultaneous Determination of Taurine, N-Acetylcysteine, Glycine and Methionine in Commercial Formulations by High-Performance Liquid Chromatography

A simple, inexpensive, reliable, selective and sensitive liquid chromatographic method was developed and validated for the simultaneous quantification of taurine (Tau), N-acetylcysteine (NAC), glycine (Gly) and methionine (Met) and applied for the first time to the analysis of commercial alimentary supplements. The amino acids (AAs) were analyzed after labeling reaction with 2,4-dinitrofluorobenzene (DNFB) in the presence of cetyltrimethylammonium bromide (CTAB). The derivatization reaction conditions were optimized and the derivatives were separated on a Phenomenex Synergi MAX-RP 4 mu m stainless steel column under gradient elution conditions. A mixture of triethylammonium (TEA) phosphate buffer (pH 3) and acetonitrile under gradient elution conditions was used as mobile phase at a flow rate of 0.4 mL/min, UV absorbance detection was set at lambda = 360 nm. Linear responses were obtained (determination coefficient >= 0.9996). Intra-day precision (RSD) was <= 1.71% for corrected peak area ratio (AA to internal standard) and <= 0.55% for retention times (t(R)) without significant differences between intra- and inter-day data. Recovery studies showed good results for all the examined compounds (from 99.26 to 99.90%; RSD <= 1.29%) %) with RSD <= 1.29%. The method was found to be specific and sensitive. The method can be useful for the quality control of commercial products. If you are interested in 768-90-1, you can contact me at any time and look forward to more communication.

Is oxidative addition indeed the rate-determining step of the Suzuki-Miyaura reaction with less-reactive aryl chlorides under ligand-free conditions?

The retarded oxidative addition of aryl chloride to Pd(0) is believed, by most scientists, to be the main hindrance in achieving effective conversion in the Suzuki-Miyaura reaction and other cross-coupling reac-tions of aryl chlorides. Herein, we have demonstrated by competing experiments, using two aryl chlorides under ligand-free catalytic conditions (absence of strong ligands; high ratio of substrate to catalyst), that the elementary step of oxidative addition is substantially reversible. This implies that the hypothesis on the rate-determining character of the oxidative addition step is incorrect, and the existing problems with aryl chloride conversion in the Suzuki-Miyaura reaction are caused by some other reasons that need to be investigated.

Effect of hyoscine-N-butylbromide on labor duration among nullipara in a southwestern Nigerian teaching hospital: A randomized controlled trial

Objective To assess the effectiveness of hyoscine-N-butylbromide on the duration of the first stage of labor among nulliparous women. Methods A randomized double-blind placebo-controlled study among 126 nulliparous women admitted in the active phase of labor to a teaching hospital in Sagamu, Nigeria, from January to August 2018. Based on the inclusion criteria, women were recruited and randomized to the study or control group, and given intravenous hyoscine-N-butylbromide 20 mg (1 mL) or sterile water (1 mL), respectively, during the active phase. Labor progress and outcomes were compared between the groups. Results The mean +/- SD duration of active phase of first stage of labor was significantly shorter in the hyoscine-N-butylbromide group (324.9 +/- 134.6 min) than in the control group (392.7 +/- 119.6 min) (P = 0.004). The rate of cervical dilatation was 1.4 +/- 0.8 cm/h in the hyoscine-N-butylbromide group and 1.0 +/- 0.5 cm/h in the control group (P = 0.004). There were no significant differences in fetal heart rate, maternal vital signs, or Apgar scores between the two groups. Conclusion Hyoscine-N-butylbromide was found to be effective in shortening the duration of the first stage of labor without adverse outcomes for mother or neonate. The trial was registered with the Pan African Clinical trials Registry (PACTR), protocol number: PACTR201808146688942 ().

Supercapacitive Performance of Surfactants Wrapped KIT-6/MCM-48 Templates Based Mesoporous Co3O4

In this paper, KIT: Korea Advanced Institute of Science and Technology No. 6 (KIT-6) and MCM: Mobil Composition of Matter No. 48 (MCM-48) mesoporous silica templates were prepared by wrapping Pluronic (P-123) and Cetyl trimethyl ammonium bromide (CTAB). Mesoporous Co3O4 geometry tailored KIT-6 and MCM-48 with different porosity were synthesized via reflux technique. Crystal geometry, morphology, molecular vibrations and pore structure were analyzed by X-Ray diffraction (XRD), scanning electron microscopy (SEM), Fourier transform infrared (FTIR) spectroscopy and Brunauer-Emmett-Teller (BET) method based N-2 adsorption-desorption for the modified materials. As expected, MCM-48 micropore-dominated electrode exhibited higher specific capacitance (442.5 F/g) which is much superior to that of KIT-6 ( 88.9 F/g). Outstanding electrochemical execution is due to the mesoporous tailored architecture (average pore diameter of 6.1 nm) and synergistic contribution of MCM-48 architectured with a Co3O4 core. This promising electrode material opens up a new platform for high-performance supercapacitors.
