Synthesis and Bioactivities of Novel Pyrazole Oxime Derivatives Containing a N-Pyridylpyrazole Moiety

In search of novel pyrazole oxime compounds with potent bioactivities, twenty pyrazole oxime derivatives were synthesized by introducing N-pyridylpymzole unit into pyrazole oxime skeleton, based on the lead of fenpyroximate. The title compounds were structurually characterized by H-1 NMR, C-13 NMR and elemental analysis. The preliminary bioassay showed that all the title compounds had 100% insecticidal activities against Mythimna separata Walker at 500 mu g/mL. Five compounds displayed 100% mortality rate towards Mythimna separata Walker at 100 mu g/mL. Two compounds both exhibited 40% mortality rate against Mythimna separata Walker at 20 mu g/mL. In addition, three compounds had 40 similar to 60% insecticidal activities to Aphis medicaginis at 500 mu g/mL. It is worthy of noting that 5-(2-bromophenoxy)-1,3-dimethyl-1H-pyrazole-4-carbaldehyde-O-{1-(3-chloropyridin-2-yl)-3-[(6-chloropy ridin-3-yl)methoxy]-1H-pyrazole-5-formyl}oxime (10b) and 5-(4-t-butylphenoxy)-1,3-dimethyl-1H-pyrazole-4-carbaldehyde-O-{1-(3-chloropyridin-2-yl)-3-[(6-chloropyridin-3-yl)methoxy]-1H-pyrazole-5-formyl}oxime (10k) which have potent insecticidal activities against Mythimna separata Walker, can be utilized in insecticide research with further optimization.

Nitrogen-Bearing Carbon Nanoparticles by Pyrolytic Decomposition of Piperazine Citrate Macromolecules for Cellular Imaging

In this work, highly photoluminescent carbon nanoparticles (CNPs) are fabricated by pyrolytic decomposition of piperazine citrate at high pressure and high temperature. Piperazine serves as a hydrolytic, surface-passivating, and N-doping agent, facilitating the formation of a photopolymer. The as-synthesized CNPs, without any surface protection/passivation, exhibit excellent photoluminescence and a maximum quantum yield of 84%. The average particle size of the N-doped CNPs is 0.89 +/- 0.05 nm. In addition, the N-doped CNPs exhibit uniform diameters and nearly spherical shapes. The X-ray photoelectron spectroscopy results reveal that the CNPs are composed of carbon (64.4 wt%), oxygen (18.5 wt%), and nitrogen (17.1 wt%), indicating the presence of nitrogen-doped and carbon-rich moieties in the CNPs. Notably, the CNPs purified by the procedure developed in this work exhibit more stable luminescence properties than those purified with the conventional dialysis membrane. In addition, the potential application of the CNPs as fluorescent bioimaging probes, which offer a broad dosing window and exhibit multicolor emission, is investigated by directly culturing A549 cells with the CNPs. The results reveal that the CNPs exhibit not only exceptional optical stability, but also outstanding biocompatibility and cell labeling capability. After incubating the A549 cells with CNPs, the CNPs are confined in perinuclear vacuole-similar shapes with a granulated form in cytoplasm preserving the nucleus. Notably, no significant morphological deterioration such as nuclear contraction is detected.

High-performance zwitterionic TFC polyamide nanofiltration membrane based on a novel triamine precursor

As known, piperazine (PIP) and m-phenylenediamine (MPD) are popularly employed as aqueous monomer to interfacially polymerize with trimesoyl chloride (TMC) for the fabrication of TFC polyamide NF and RO membrane, respectively. In this work, we designed a novel amine monomer 4-(piperazin-1-yl)benzene-1,3-diamine (PMPD) having the combined PIP and MPD units in one molecule and employing it with TMC to prepare the pristine nanofiltration membrane. Subsequently, zwitterionic antifouling PA surface was constructed by modification with 3-bromopropionic acid (3-BPA). The resulting membrane (PMPD-PA) exhibited a smoother surface with enhanced surface hydrophilicity than the membrane made from MPD, and the thickness of the PA active layer was down to similar to 35 nm. Meanwhile, its pure water permeability was-19 L m(-2) h(-1) bar(-1), with Na2SO4 rejection of 98.4%, and NaCl rejection as low as 24.1%, performing as a novel selective NF membrane. Furthermore, fouling tests using model foulants BSA and SA well illustrated the good antifouling properties of membrane PMPD-PA with the mitigated flux decline and enhanced flux recovery upon physical cleaning. Thus, this work further demonstrates the fabrication of high-performance TFC NF membrane from the perspective of molecular design.

High-Flux Fine Hollow Fiber Nanofiltration Membranes for the Purification of Drinking Water

High-flux fine hollow fiber nanofiltration (HFNF) membranes were prepared by interfacial polymerization (IP) using polysulfone (PSF) ultrafiltration (UF) membranes with an outer diameter of 425 mu m as the substrate for the treatment of drinking water. Trimesoyl chloride (TMC) was selected as the organic phase monomer, while poly(vinyl alcohol) (PVA) was added into piperazine (PIP) aqueous phase solution to reduce the surface defects and to enhance the separation performance of the NF membrane. The as-prepared fine HFNF membranes had a large packing density and effective area. The optimal preparation conditions of the fine HFNF membrane were determined by orthogonal experiments in which the flux of the membrane reached 34.2 +/- 1.5 L.m(-2).h(-1).bar(-1), while its salt rejection sequence was as follows: Na2SO4 (97.6 +/- 1.5%) > MgSO4 (96.1 +/- 1.8%) > MgCl2 (83.5 +/- 2.1%) > NaCl (27.9 +/- 2.6%). During the long-term stability test for 132 h, the membrane retained a high flux (>23.7 +/- 1.5 L.m(-2).h(-1).bar(-1)) and high Na2SO4 rejection (>97.2 +/- 1.1%). Additionally, it exhibited huge potential for application in drinking water purification in which the as-prepared NF membrane exhibited excellent antifouling performance for bovine serum albumin (BSA).

A Hybrid Membrane-Absorption Process for Carbon Dioxide Capture: Effect of Different Alkanolamine on Energy Consumption

Amine and membrane-based processes are commonly used to treat acid gases such as carbon dioxide and hydrogen sulfide. Carbon dioxide adversely affects the environment, therefore, its utilization and storage are critical. In this work, a simplistic approach of single-stage membrane units combine with amine absorption processes with different commercial amines was investigated. An increase in CO2 concentration in the feed gas results in a substantial increase in the thermal energy consumption of the stripper reboiler were using a hybrid amine-membrane setup can effectively reduce energy consumed in the reboiler. Both the amine absorption process and membrane process are simulated using Aspen HYSYS V10. Since the membrane is not available in Aspen HYSYS V10 unit operation package; it is programmed and added as custom user operation. Moreover, a new acid/ amine-based fluid package builds in a combination of the Peng-Robinson equation of state for vapor phase and electrolyte non-random two liquid-based activity model for the liquid phase were used in this study. Furthermore, energy consumption in CO2 capture using different alkanolamine such as N-methyldiethanolamine (MDEA), monethanolamine (MEA), deithanolamine (DEA), piperazine (PZ), triethanolamine (TEA) are also studied. As membrane unit help in CO2 reduction in feed to amine absorption process in hybrid amine-membrane setup. This significantly reduces the energy requirement as compared to the conventional standalone alkanolamine process. In comparison with various amines used in the amine absorption process, MEA offers the lowest total energy consumed, whereas, MDEA is considered to be the highest in terms of energy consumption.

Alterations in Mediterranean mussel (Mytilus galloprovincialis) composition exposed to cyanotoxins as revealed by analytical pyrolysis

Cylindrospermopsin (CYN) and Microcystin-LR (MC-LR) are biotoxins produced by cyanobacteria species that, due to climate change and water eutrophication, proliferate together with an increase of the associated cyanotoxins. Both toxins are usually found in the aquatic environment and filter feeding organisms such as mussels are particularly exposed which may be the cause of metabolic alterations. In this work, pyrolysis gas chromatography mass spectrometry (Py-GC/MS) is used to evaluate compositional changes in mussel (M. galloprovincialis) after exposure for 14 days to cyanotoxins of Chrysosporum ovalisporum (CYN), Microcystis aeruginosa (MC-LR) and to a combination of both toxins. The pyrolysis of mussel flesh produced complex chromatograms, with up to 100 different compounds, but very similar between treatments. Major groups found were N compounds (pyridine, N-alkyl molecules) (18.2 % +/- 1.5) and peptide/protein derived compounds that include alkyl indols and diketo-piperazines (DKPs) (17.7 % +/- 2.4), series of medium chain length (C-14-C-22) saturated, mono and polyunsaturated fatty acids (45.1 % +/- 5.0), steroids (7.5 % +/- 0.6) and aromatics with undetermined origin (8.9 % +/- 1.1). A chemometric treatment of the chromatographic data allowed the discrimination between the different mussel populations exposed to cyanotoxins. The results are discussed in terms of the probable effects exerted by the biotoxins in mussel composition and the possible metabolic pathways affected.

An entry to non-racemic beta-tertiary-beta-amino alcohols, building blocks for the synthesis of aziridine, piperazine, and morpholine scaffolds

A method for the preparation of enantiopure beta-tert-amino alcohols bearing a tetrasubstitutedC-stereocenter, as well as their conversion into selected medicinally privileged heterocyclic systems (morpholines, aziridines, piperazines) is reported. These compounds were obtained through enantiospecific sigmatropic rearrangement of allyl carbamates as a key step. The latter were prepared from the corresponding beta,beta ‘-dialkyl-substituted non-racemic allyl alcohols. In addition, an asymmetric synthesis of such highly substituted allylic alcoholsviaeither enantioselective 1,2-reduction of enones, enzymatic kinetic resolution, or a functionalization of chiral propargyl alcohols, with discussion of scope and limitations of each method is reported.

Rapid Qualitative Analysis of New Psychoactive Substances by Infrared Spectroscopy

In this study, the infrared spectra (IR) of 301 new psychoactive substances (NPS) reference substances, including 100 synthetic cannabinoids, 81 synthetic cathinone, 42 phenethylamines, 9 tryptamines, 5 piperazines, 7 phencyclidine-type substances, 2 aminoindanes, 55 other types, were analyzed. The discriminant ability of IR for NPS, especially for NPS structural analogues, was investigated. The result showed that IR could well distinguish all kinds of NPS, even for some analogues with high spectrum similarity. IR has a high discrimination ability for 97% NPS, including alkyl chain-substituted regioisomers, ring-substituted regioisomers, different benzene ring disubstituted analogues, etc. The matching coefficient method is commonly used for spectral library search. The calculated matching coefficient value depends on several factors such as the quality of spectrum, software, algorithm, etc. so it is difficult to determine a universal threshold for positive detection. Therefore, the matching coefficient method can be only used for preliminary screening. Compared with the matching coefficient method, the characteristic peak method is more accurate and reliable for qualitative identification. Generally, eight absorption peaks with relatively high intensity in the range of 2500 similar to 650 cm(-1) are selected as characteristic peaks, but for some NPS structural analogues with similar spectra, it is necessary to select some low intensity but distinguishable peaks as characteristic absorption peaks. Only when all the characteristic absorption peaks are detected can the positive detection be concluded. According to this principle, characteristic absorption peaks of 168 regulated NPS were determined, and formed the IR method part of the industry standard Forensic sciences Examination methods for 168 new psychoactive substances including 2-FA in suspected drugs GC-MS, IR and LC. The rapid qualitative analysis of NPS by infrared spectroscopy based on a characteristic peak method will greatly improve the efficiency and reduce the cost of NPS qualitative identification analysis.
