Development of an analytical methodology for the analysis of priority cytostatics in water

The consumption of cytostatics has remarkably increased over the last years due to the high cancer incidence worldwide. In previous studies, seven cytostatics were already recognized to potentially induce chronic effects in aquatic organisms, taking into account their estimated concentrations in surface waters: cyclophosphamide (CYC), capecitabine (CAP), mycophenolic acid (MPA), imatinib (IMA), bicalutamide (BICA), prednisone (PRED) and 5-fluorouracil (5FU). The objective of the present study was to simultaneously analyse these 7 prioritized compounds, which have the highest chances to be found in surface and wastewaters. The analytical challenge relies in the determination of these very polar compounds, which have different chemical and structural properties. Solid-phase extraction with an Ultra Performance Liquid Chromatograph-Mass Spectrometer in electrospray ionization mixed mode (5-fluorouracil and bicalutamide in negative mode and the others in positive one) was developed to determine seven cytostatics in wastewater and surface water. Among eight tested cartridges with different sorbents and conditions, the best extraction performance was attained with Oasis WAX at pH 10, with recoveries ranging from 31 +/- 4 (5FU) and 103 +/- 17% (MPA). Regarding the chromatographic analysis, the best results were achieved with an XBridge amide column. The final analytical methodology was successfully applied for the analysis of real water samples, confirming the presence of risky cytostatics in surface and wastewaters. (c) 2018 Elsevier B.V.

Design and synthesis of biaryloxazolidinone derivatives containing amide or acrylamide moiety as novel antibacterial agents against Gram-positive bacteria

A series of novel biaryloxazolidinone derivatives containing amide and acrylamide structure were designed, synthesized and evaluated for their antibacterial activity. Most compounds generally exhibited potent antibacterial activity with MIC values of 1 mu g/mL against S. aureus, MRSA, MSSA, LREF and VRE pathogens, using linezolid and radezolid as positive controls. Compound 17 exhibited good antibacterial activity with MIC values of 0.5 mu g/mL against S. aureus, MRSA, MSSA and VRE and 0.25 mu g/mL against LREF. The results indicated that compound 17 might serve as a potential hit-compound for further investigation.

Nitric Oxide (NO) separation from flue gas by chemical modified mesoporous silica

Three kinds of chemically modified silica were prepared to adsorb NO by surface modifying with vinyltriethoxysilane, acrylic acid and acryl amide respectively, and characterized by N-2 adsorption experiments, Fourier transform infrared spectroscopy, scanning electron microscopy and thermo-gravity analysis. The results showed that -COOH and -CONH2 in the monomers had been grafted on the silica surface, and the pore volumes of S-1, S-2 and S-3 decreased and exhibited the mesoporous structure; all the modified adsorbents could maintain steady under 300 degrees C. NO adsorption experiments were also carried out and the results suggested that the silica modified with acryl amide had the best NO adsorption capacity due to the relative large surface area and the stronger hydrogen bonds between NO molecules and the functional groups. The adsorbed NO molecules could be well desorbed by purging with N-2 so that the adsorbents could be recycled and NO resource also had the chance to be reused.

Solid-state structure of cyclic dipeptides: an X-ray and computational study of cis- and trans-diketo-piperazines of N-methyl-phenylalanine with the thia-pipecolic acids and thia-prolines

Ten new crystal structures of cis and trans bicyclic diketopiperazines (DKPs) of thia-pipecolic acid (with sulfur in the beta, gamma or delta position) or thia-proline (with sulfur in the beta or gamma position) and N-methyl phenylalanine [(NMe) Phe]: cyclo[(beta-S) Pip-(NMe) Phe], cyclo[(gamma-S) Pip-(NMe) Phe], cyclo[(delta-S) Pip-(NMe) Phe], cyclo[(beta-S) Pro-(NMe) Phe] and cyclo[(beta-S) Pro-(NMe) Phe] were determined with X-ray crystallography. Density functional theory calculations of these molecules in the gas phase succeed in reproducing the observed molecular conformations in the crystal remarkably well. This illustrates the weak to moderate impact of intermolecular packing forces in the absence of classical N-H center dot center dot center dot center dot O hydrogen bonds. The effect of sulfur on the geometry of the DKP ring and details of amide bond non-planarity are discussed. Molecular flexibility of the DKP ring, as estimated from the calculated deformation energies of its endocyclic ring torsion angles, is not in general the decisive factor for the occurrence of multiple symmetry independent molecules in the unit cell (Z’ > 1), though in some cases a correlation is observed.

Selective coordination with heterogeneous metal atoms for inorganic-organic hybrid layers

The synthesis of organic-inorganic hybrid materials using individual metal-organic molecules as building blocks has been of interest for the last few decades. These hybrid materials are appealing due to the opportunities they provide with respect to a variety of potential applications. Here, we report a novel metal-organic nanostructure made by a hybrid synthetic process that is comprised of thermal evaporation (TE) and atomic layer deposition (ALD) for the metalation of an organic layer. In this work, 5,10,15,20-tetrakis(4-hydroxyphenyl)-21H,23H-porphyrin (p-(H-6)THPP) and tin(ii) bis(trimethylsilyl)amide (Sn(btsa)(2)) (or diethylzinc (DEZ)) were utilized as the main organic layer and ALD precursors, respectively. Sn and Zn atoms were coordinated sequentially via surface chemical reactions on specific functional groups of the p-(H-6)THPP layer, which was deposited on a solid substrate. X-ray photoelectron spectroscopy (XPS) and UV-vis absorption spectroscopy were used to characterize and confirm the growth mechanism and optical properties of the synthesized hybrid films. This method should serve as a major breakthrough for building advanced organic-inorganic materials-based devices.

Revisiting OPLS Force Field Parameters for Ionic Liquid Simulations

Our OPLS-2009IL force field parameters (J. Chem. Theory Comput. 2009, 5, 1038-1050) were originally developed and tested on 68 unique ionic liquids featuring the 1-alkyl-3-methylimidazolium [RMIM], N-alkylpyridinium [RPyr], and choline cations. Experimental validation was limited to densities and a few, largely conflicting, heat of vaporization (Delta H-vap) values reported in the literature at the time. Owing to the use of Monte Carlo as our sampling technique, it was also not possible to investigate the reproduction of dynamics. The [RMIM] OPLS-2009IL parameters have been revisited in this work and adapted for use in molecular dynamics (MD) simulations. In addition, new OPLS-AA parameters have been developed for multiple anions, i.e., AlCl4-, BF4 (_) ,Br- , Cl- , NO3- , PF6- , acetate, benzoate bis(pentafluoroethylsulfonyl)amide, bis(trifluoroethylsulfonyl)amide, dicyanamide, formate, methylsulfate, perchlorate, propanoate, thiocyanate, tricyanomethanide, and trifluoromethanesulfonate. The computed solvent densities, heats of vaporization, viscosities, diffusion coefficients, heat capacities, surface tensions, and other relevant solvent data compared favorably with experiment. A charge scaling of +/- 0.8 e was also investigated as a means to mimic polarization and charge transfer effects. The 0.8-scaling led to significant improvements for Delta H-vap, surface tension, and self-diffusivity; however, a concern when scaling charges is the potential degradation of local intermolecular interactions at short ranges. Radial distribution functions (RDFs) were used to examine cation-anion interactions when employing 0.8*OPLS-2009IL and the scaled force field accurately reproduced RDFs from ab initio MD simulations.

Application of 13734-41-3, Consequently, the presence of a catalyst will permit a system to reach equilibrium more quickly, but it has no effect on the position of the equilibrium as reflected in the value of its equilibrium constant.I hope my blog about 13734-41-3 is helpful to your research.

Intercalation Structure and Enhanced Thermal Oxidative Stability of Polyamide 6/Graphene Nanocomposites Prepared through in Situ Polymerization

Polyamide 6 (PA6)/graphene oxide (GO) nanocomposites were prepared through the in situ polymerization method. GO layers were partially reduced, exfoliated by intercalation of PA6 molecules with a high intercalation ratio, and dispersed uniformly in the matrix without obvious aggregation. The crystalline form of PA6 transformed from the gamma-form to the alpha-form by addition of GO, and the network structure centering on GO formed through the intermolecular interaction between the two phases. During the thermoaging process, compared with pure PA6, the reduced viscosity and tensile strength of the composite remained at a high level, and the carbonyl index increased much more slowly. In addition, the degradation temperature increased, the degradation rate decreased, and the activation energy changed slightly, indicating the enhanced thermal oxidative stability of PA6. With increasing GO content, the oxygen permeability coefficient decreased significantly, and the radical scavenging ratio increased, which was favorable for inhibiting the oxidative degradation of PA6 molecules.

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 5813-64-9. Name: 2,2-Dimethylpropan-1-amine.

Incorporation of a hydrophilic amide monomer into a one-step self-etch adhesive to increase dentin bond strength: Effect of application time

The purpose was to evaluate the effect of a hydrophilic amide monomer on mu TBS of one-step adhesive to dentin at different application times. Clearfil Universal Bond Quick (UBQ), experimental adhesive (UBQ(exp); same compositions as UBQ but hydrophilic amide monomer was replaced with 2-hydroxyethyl methacrylate), Clearfil SE ONE and Clearfil SE Bond were applied to midcoronal dentin prepared with 600-grit SiC at different application time (0, 10, 20 and 40 s). Water sorption (Wsp) and the ultimate tensile strength (UTS) of polymerized adhesives were also measured. UBQ showed significantly lower Wsp and higher UTS than UBQ(exp). At each application time, UBQ exhibited significantly higher mu TBSs than UBQ(exp). UBQ showed the highest mu TBS at 0 s application time among all the adhesives. When the application time was prolonged from 0 s to 10 s, only UBQ showed no significant difference. The hydrophilic amide monomer increased TBS with reduction in Wsp and increase in the UTS and may allow a shortened application time.
