Custom-tailoring metal-organic framework in thin-film nanocomposite nanofiltration membrane with enhanced internal polarity and amplified surface crosslinking for elevated separation property

A polyamide (PA) thin-film nanocomposite (TFN) membrane embedded with post-synthetically functionalized metal-organic framework (MOF) nanofillers of imidazole-2-carbaldehyde (ICA) decorated UiO-66-NH2 nano fillers (ICA_d_UiO-66-NH2) was developed using the interfacial polymerization method. The ICA_d_UiO-66-NH2 nanofiller couples a surface water-capturing ICA decoration, facilitating the rapid transport of water molecules owing to the enhanced internal polarity, while achieving an amplified crosslinking between the terminal amine groups of ICA and trimesoyl chloride, enabling the perfect incorporation of MOF nanofillers within the PA matrix. The resultant ICA_d_UiO-66-NH2@PA TFN membrane with elevated separation property performed comparably high water permeance of 9.4 l m(-2) h(-1) bar(-1) (achieving a nearly 2-fold increase from the initial value of the thin-film composite membrane), and a favorable rejection ratio of 97.4% (Na2SO4). Owing to the unique hierarchical surface microstructure embedded with the intrinsically hydrophilic ICA_d_UiO-66-NH2 nanofillers, the newly-developed TFN membrane exhibited superior antifouling properties. Furthermore, the ICA_d_UiO-66-NH2@PA TFN membrane also retained excellent reusability and durability without significant compromise even after long-term salt, and acid/alkali treatments. Overall, this work provides an insight into the embedding of different functionalized nanofillers inside TFN membranes with elevated separation properties.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 109-01-3, you can contact me at any time and look forward to more communication. Computed Properties of C5H12N2.

Occurrence and Mass Loading of Synthetic Opioids, Synthetic Cathinones, and Synthetic Cannabinoids in Wastewater Treatment Plants in Four US Communities

A few new psychoactive substances (NPS) that mimic the effects of controlled neuropsychiatric and illicit drugs have been forensically identified in the U.S. Wastewater-based epidemiology (WBE) can provide a comprehensive and more cost- and time-effective method of determining the prevalence of NPSs in communities. In this study, an analytical method capable of simultaneous determination of trace-level 40 NPS residues (synthetic opioids, synthetic cannabinoids, synthetic cathinones, piperazines, indole, and amphetamine) in wastewater was developed and validated. The developed analytical method was utilized to determine the occurrence of NPSs in four rural communities in southern Illinois. Nine NPSs (carfentanil, furanyl fentanyl, methoxyacetyl fentanyl, MAB-CHMINACA, methcathinone, 4-methyl pentedrone, 2-methyl-4′-(methylthio)-2-morpholinopropiophenone (MMMP), 1-(3-chlorophenyl) piperazine (mCPP), and 5-(2- Aminopropyl) Indole (SIT) were quantified. Methcathinone was the most frequently detected NPS (detection frequency, df = 100%) followed closely by the MMMP and mCPP (df = 91%). The mass loading of methcathinone, mCPP, and S-IT using ammoniacal nitrogen-based population were up to 21.1 +/- 1.3 mg/d/1000 people, 15.0 +/- 0.5 mg/d/1000 people, and 9.75 +/- 2.72 mg/d/1000 people, respectively. This is the first study to determine the occurrence of NPSs including synthetic opioids, synthetic cannabinoids, synthetic cathinones, and piperazines in the U.S. communities.

Anodic oxidation of ciprofloxacin using different graphite felt anodes: Kinetics and degradation pathways

Ciprofloxacin (CIP) is ubiquitous in the environment which poses a certain threat to human and ecology. In this investigation, the physical and electrochemical properties of graphite felt (GF) anodes which affected the anodic oxidation (AO) performance, and the CIP removal effect of GF were evaluated. The GFs were used as anodes for detection of center dot OH with coumarin (COU) as molecule probe and removal of CIP in a 150 mL electrolytic cell with Pt cathode (AO-GF/Pt system). The results showed that hydrophilic GF (B-GF) owned higher sp(3)/sp(2) and more oxygen-containing and nitrogen-containing functional groups than the hydrophobic GF (A-GF). Moreover, B-GF possessed higher oxygen evolution potential (1.12 V), more active sites and stronger center dot OH generation capacity. Above mentioned caused that B-GF exhibited more superior properties for CIP removal. The best efficiencies (96.95%, 99.83%) were obtained in the AO-B-GF/Pt system at 6.25 mA cm(-2) after 10 min (k(1), 0.356 min(-1)) and 60 min (k(2), 0.224 min(-1)), respectively. Furthermore, nine degradation pathways of CIP in AO-B-GF/Pt system were summarized as the cleavage of the piperazine ring, cyclopropyl group, quinolone ring and F atom by center dot OH. It provides new insights into the removal and degradation pathways of CIP with GF in AO system.

10-(4-Phenylpiperazine-1-carbonyl)acridin-9(10H)-ones and related compounds: Synthesis, antiproliferative activity and inhibition of tubulin polymerization

As part of our continuing search for potent inhibitors of tubulin polymerization, two novel series of 42 10-(4-phenylpiperazine-1-carbonyl)acridin-9(10H)-ones and N-benzoylated acridones were synthesized on the basis of a retrosynthetic approach. All newly synthesized compounds were tested for antiproliferative activity and interaction with tubulin. Several analogs potently inhibited tumor cell growth. Among the compounds tested, 10-(4-(3-methoxyphenyl)piperazine-1-carbonyl)acridin-9(10H)-one (17c) exhibited excellent growth inhibitory effects on 93 tumor cell lines, with an average GI(50) value of 5.4 nM. We were able to show that the strong cytotoxic effects are caused by disruption of tubulin polymerization, as supported by the EBI (N,N’-Ethylenebis(iodoacetamide)) assay and the fact that the most potent inhibitors of cancer cell growth turned out to be the most efficacious tubulin polymerization inhibitors. Potencies were nearly comparable or superior to those of the antimitotic reference compounds. Closely related to this, the most active analogs inhibited cell cycling at the G2/M phase at concentrations down to 30 nM and induced apoptosis in K562 leukemia cells. We believe that our work not only proves the excellent suitability of the acridone scaffold for the design of potent tubulin polymerization inhibitors but also enables synthetic access to further potentially interesting N-acylated acridones.

CO2 absorption rate in biphasic solvent of aminoethylethanolamine and diethylethanolamine

Amine scrubbing is currently the most promising technology for CO2 capture from gas turbine and coal-fired flue gas. It is hindered by high regeneration energy and high capital cost. Biphasic solvent of 25% aminoethylethanolamine (AEEA)/50% diethylethanolamine (DEEA) could be a potential solution as it may achieve significant reduction in regeneration energy. A fast CO2 absorption rate is preferred to reduce the capital cost of the absorber. In this work, the CO2 absorption rate (k g’) of the biphasic solvent was measured in a wetted wall column at 40 degrees C and at the loading conditions in the absorber. At CO2 equilibrium partial pressure (P-CO2*) lower than 100 Pa, 25% AEEA/50% DEEA is homogeneous. The CO2 absorption rate, kg, is as fast as 30% PZ (3 times faster than 30% MEA). When P-CO2* is greater than 100 Pa, 25% AEEA/50% DEEA forms aqueous and organic phases after CO2 absorption. It was first found that the organic phase of 25% AEEA/50% DEEA absorbs CO2 2-7 times faster than the aqueous phase because of greater physical CO2 solubility at the same P-CO2* and physical mass transfer coefficient. The kg’ of the organic phase is much faster than 30% MEA and 25% AEEA at lean and rich loading and even greater than 30% PZ at lean loading. The instantaneous reaction mechanism fits the kinetics of CO2 absorption in the organic phase at low P-CO2*. The slow kg’ of the aqueous phase results from greater viscosity which significantly reduces the physical mass transfer coefficient. The CO2 capacity of the aqueous phase is 2.9 times, 1.8 times, and 5.3 times greater than that of 30% MEA, 30% PZ, and the organic phase, respectively.

Multi-Stimuli Responsive Luminescent beta-Diketones and Difluoroboron Complexes with Heterocyclic Substituents

Emissive beta-diketones (bdks) and difluoroboron complexes (BF(2)bdks) exhibit multi-stimuli responsive luminescence, including solvatochromism, viscochromism, aggregation induced emission, thermal and mechanochromic luminescence, halochromism and pH sensing. In this study, a series of six-membered heterocycle-substituted (piperidine, morpholine, 1-methyl piperazine) bdk ligands and boron complexes were synthesized, and their luminescent properties were investigated. All the compounds exhibited red-shifted emission in more polar solvents due to intramolecular charge transfer as well as higher emission intensity in more viscous environments. In response to solubility changes in water/tetrahydrofuran mixtures, while the piperazine bdk ligand showed aggregation caused quenching, the piperidine and morpholine bdks displayed enhanced emission upon aggregation. In the solid state, all ligands exhibited mechanochromism. More dramatic halochromism was observed for the piperidine boron dye spin cast film. In solution, for the boron dyes under varying pH values (1-13), different protonated and deprotonated forms were analyzed according to the measured emission spectra.

Near-infrared pH responsive heptamethine cyanine platforms: Modulating the proton acceptor

In this report, we wish to present the rational design, synthesis, and study of optical characteristics of near-infrared (NIR) molecular probes emitting over 800 nm. The title pH sensing platforms consist of a piperazine moiety serving as a hydronium ion receptor, coupled with a rigidified symmetric heptamethine backbone. The spectrally fine-tuned response of the fluorophores was studied in both organic solvents and aqueous buffer solutions, employing combined UV-Vis and steady state fluorimetric techniques. In parallel, computational approach and optical spectroscopy were employed aiming to ascribe the origin of spectral behavior of the amino-substituted heptamethines. Herein, we also investigated the halochromic effect of the differently substituted piperazines on the spectral properties of the NIR cyanine dyes. Under acidic conditions, the protonation of the piperazine moiety promoted a gradual bathochromic shift in the absorption spectra. The Delta lambda between the neutral and the protonated forms are indirectly related to the modifications applied to the proton acceptor. The calculated pK(a) values (5.13-7.06) were found to be dependent on the dye chemical structure. A good linear correlation was established between the pK(a) of the newly synthesized dyes and that of the reported piperazine moieties. This aspect allows the future expansion of the current facile strategy since sensing chromophores with predicted pH response could readily be designed based on pK(a) databases for substituted piperazine derivatives. A detailed literature study along with NMR and computational methods were found to be in agreement with our assumption, that both nitrogen atoms of the 1,4-disubstituted amine are involved in the sensing process. The covered pK(a) range allows us to recommend the title fluorophores as promising potential candidates for qualitative analysis of biological samples. A cytotoxicity study by the MTT assay showed that the NIR dyes are safe and applicable for bioanalytical purposes at dye concentrations up to 10 mu M. Fluorescence imaging and cellular applications, including staining and visualization of HeLa cervical cancer cells was successfully demonstrated.

AdeABC Efflux Pump Controlled by AdeRS Two Component System Conferring Resistance to Tigecycline, Omadacycline and Eravacycline in Clinical Carbapenem Resistant Acinetobacter nosocomialis

Carbapenem-resistant Acinetobacter nosocomialis (CRAn) is a significant public health concern. Tigecycline non-susceptible CRAn (Tn-CRAn) isolates have emerged worldwide. Tigecycline resistance is mainly related to the overexpression of AdeABC efflux pump controlled by AdeRS two-component system (TCS). Two novel tetracycline derivatives, omadacycline and eravacycline, may present a treatment option for CRAn. This study investigated the in vitro antimicrobial activity of tigecycline, omadacycline and eravacycline against clinical CRAn isolates and the contribution of efflux pumps in their resistance. Eighty-nine clinical CRAn isolates, including 57 Tn-CRAn isolates were evaluated for minimum inhibitory concentrations (MICs) by the broth microdilution. The relationship between the antimicrobial resistance and efflux pump expression was assessed by their responses to the efflux pump inhibitor 1-(1-naphthylmethyl)-piperazine (NMP). The contribution of the AdeABC efflux pump in their resistance was determined by the complementation of the AdeRS two-component system in wild-type, adeRS operon and adeB gene knockout strains. Among the 89 isolates, omadacycline and eravacycline MICs were correlated closely with those of tigecycline. They demonstrated improved potency, based on MIC90 values, by showing a 4 to 8-fold greater potency than tigecycline. The synergetic effects of tigecycline, omadacycline and eravacycline with NMP were observed in 57 (100%), 13 (22.8%), and 51 (89.5%) of Tn-CRAn isolates, respectively. Further analysis showed that the laboratory strain carrying the Type 1 adeRS operon increased the tigecycline, omadacycline and eravacycline MICs by 4-8-folds, respectively. Eravacycline demonstrated improved potency over tigecycline against populations of CRAn, including Tn-CRAn isolates. The over-expression of AdeABC efflux pumps was directly activated by the AdeRS two-component system and simultaneously reduced the susceptibilities of tigecycline, eravacycline, and omadacycline. Omadacycline and eravacycline MICs were correlated closely with those of eravacycline.
