Three kinds of novel hydroxyapatite@terbium complex core-shell composites were synthesized with 2-chlorobenzoic acid, 4-chlorobenzoic acid, and 2,4-dichlorobenzoic acid as the ligand, respectively. The XRD, UV/vis absorption and FT-IR results show that terbium ions are coordinated with ligands and the corresponding complexes are successfully included into composites. SEM and EDS results reveal that Tb complexes are fully and homogenously coated on the surface of hydroxyapatite (HAP) microspheres consisting of a large number of nanosized crystals. The strongest luminescence properties are obtained when 2,4-dichlorobenzoic acid is used as ligand. The study on fluorescence lifetime of composites shows that the lifetime is inversely related to emission intensity. TGA-DSC results indicate that the core-shell composites have an excellent thermal stability. Therefore, the current core-shell structure provides a cost-effective route to manufacture of biocompatible and heat-resistant highly luminescent materials. (C) 2020 Chinese Society of Rare Earths.

The anionic form-dependent binding interaction of halo-phenolic substances with human transthyretin (hTTR) has been observed previously. This indicates that ionizable compounds should be the primary focus in screening potential hTTR disruptors. Here, the potential binding potency of halo-benzoic acids, halo-benzenesulfonic acids/sulfates and halo-phenylboronic acids with hTTR was determined and analyzed by competitive fluorescence displacement assay integrated with computational methods. The laboratorial results indicated that the three test groups of model compounds exhibited a distinct binding affinity to hTTR. All the tested halo-phenylboronic acids, some of the tested halo-benzoic acids and halo-benzenesulfonic acids/sulfates were shown to be inactive with hTTR Other halo-benzoic acids and halo-benzenesulfonic acids/sulfates were moderate and/or weak hTTR binders. The binding affinity of halo-benzoic acids and halo-benzenesulfonic acids/sulfates with hTTR was similar. The low distribution ability of the model compounds from water to hTTR may be the reason why they exhibited the binding potency observed with hTTR. By introducing other highly hydrophobic compounds, we observed that the binding affinity between compounds and hTTR increased with increasing molecular hydrophobicity. Those results indicated that the highly hydrophobic halo-benzoic acids and halo-benzenesulfonic acids/sulfates may be high-priority hTTR disruptors. Finally, a binary classification model was constructed employing three predictive variables. The sensitivity (S-n), specificity (S-p), predictive accuracy (Q) values of the training set and validation set were >0.83, indicating that the model had good classification performance. Thus, the binary classification model developed here could be used to distinguish whether a given ionizable compound is a potential hTTR binder or not. (C) 2019 Elsevier Ltd. All rights reserved.

Unlike other DNA topoisomerase II (topo II) inhibitors, our recently identified acridone derivative E17 exerted strong cytotoxic activity by inhibiting topo II without causing topo II degradation and DNA damage, which promoted us to explore more analogues of E17 by expanding its chemical diversification and enrich the structure-activity relationship (SAR) outcomes of acridone-oriented chemotypes. To achieve this goal, 42 novel acridone derivatives were synthesized and evaluated for their antiproliferative efficacies. SAR investigations revealed that orientation and spatial topology of R-3 substituents make greater contributions to the bioactivity, exemplified by compounds E24, E25 and E27, which has provided valuable information for guiding further development of acridone derivatives as promising drug candidates.

Dual effects of cathodic dechlorination and oxidative decomposition of 2,4-dichlorobenzoic acid (2,4-DCBA) can be achieved using electrochemical reduction-oxidation technology. The removal efficiency was improved by optimizing the experimental conditions affecting electrode activity and contaminant degradation. The 2,4-DCBA removal efficiency reached 90.8% at a current density at 50 mA.cm(-2), initial pH of 5, and sodium sulfate concentration of 0.05 mol.L-1, with a 2,4-DCBA concentration of 20 mg.L-1. Furthermore, a good total organic carbon removal efficiency of 81.6% was achieved in the electrocatalytic reduction and oxidation process, with the present system retaining high stability after many experiment cycles. The reaction mechanism under different conditions is discussed, which provides new approaches to the degradation of chlorinated organic compounds.

In this study, the transformation characteristics of fluorescent dissolved organic matter (FDOM) were investigated to characterize the removal of dissolved organic matter (DOM) during biological treatment of commingled chemical industrial wastewater. The results of fluorescence excitation and emission spectroscopy and parallel factor analysis revealed three components (C1, C2, and C3) of FDOM, which were related not only to surface and sewage sources but also chemical industrial wastewater sources. Resin fractionation results showed that the removal of DOM was affected not only by substrate biodegradability but also by DOM generation, such as intermediates, end products, and soluble microbial products, during biological treatment. However, the same variation tendency between DOM and FDOM, based on molecular weight (MW) distribution, was observed during MW fractionation. The changes in DOM in MW>10 kDa fraction apparently corresponded with C2 variation; the tendency of DOM removal in MW of 0.5-10 kDa fraction was possibly related to the evolutions of all three components; and lastly, the removal of DOM in MW<0.5 kDa fraction was found in accordance with C1 and C3 transformations. The removal and transformation of DOM and FDOM were investigated using gas chromatography-mass spectrometer and Fourier transform infrared spectroscopy. COA of Formula: C7H4Cl2O2.

Chemoselective approaches were developed for derivatizing diastereoselective chromanone spiro-gamma-lactams through the Michael-type addition by using amide as a weak nucleophile to construct the spiro-carbon center under basic conditions. To expand the scope of this post-Ugi cascade reaction, a new series of oxidized chromone derivatives was synthesized by altering solvent from EtOH to DMF. Compounds 7 a and 7 b which could be synthesized in one day, demonstrated comparable anticancer activities with legendary anticancer drug paclitaxel in the PANC and U87 cell lines. This methodology offers a new approach to construct spiro-carbon centers with functionalized chromanones or chromones under mild reaction conditions.

In this paper, synthesized Fe3O4 nanoparticles applied as catalyst in photodegradation of Direct Red 23 (DR23) dye using photo-Fenton process in aqueous solution. The Fe3O4 nanoparticles were characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD) and Fourier transform infrared spectroscopy (FT-IR). Design of experiments (DOE) based on Taguchi approach was used. Analysis the response of each experiment was based Signal to Noise (S/N) ratio was calculated. The effective parameters for the degradation of dye were determined and optimized using Taguchi (L-9 (3(4))) orthogonal array experimental design method with four factors having three levels for each factor. The Taguchi approach showed that pH 3 (level 1), catalyst amount = 25 mg/L (level 2), H2O2 concentration = 15 ppm (level 3), and temperature = 35 degrees C (level 3) was optimum conditions for this process. The factor most influencing the process was determined using analysis of variance (ANOVA) method. The most significant factor in this process was pH. The interaction between pH x catalyst amount was the most influencing interaction. The percent (p (%)) of each factor on the degradation of dye was found to be in the following the order: pH (50.306%), catalyst amount (6.887%), H2O2 concentration (39.272%), and temperature (3.456%). The percentage contribution of factors in this process was found to be in the following the order: pH (0.332), catalyst amount (0.101), H2O2 concentration (0.291), and temperature (0.082). So first order reaction with k = 0.0472 min(-1) was observed for the photocatalytic degradation reaction.

N-benzhydrylpiperazine and 1,3,4-oxadiazoles are pharmacologically active scaffolds which exhibits significant inhibitory growth effects against various cancer cells, however, antiproliferation effects and the underlying mechanism for inducing apoptosis for aforementioned scaffolds addressing HeLa cancer cells remains uncertain. In this study, N-benzhydrylpiperazine clubbed with 1,3,4-oxadiazoles (4a-4h) were synthesized, subsequently characterized using high resolution spectroscopic techniques and eventually evaluated for their antiproliferation potential by inducing apoptosis in HeLa cancer cells. The MTT assay screening results revealed that among all, compound 4d (N-benzhydryl-4-((5-(4-aminophenyl)-1,3,4-oxadiazol-2-yl)methyl)piperazine) in particular, exhibited IC (50) value of 28.13 +/- 0.21g/mL and significantly inhibited the proliferation of HeLa cancer cells in concentration-dependent manner. The in vitro anticancer assays for treated HeLa cells resulted in alterations in the cell morphology, reduction in colony formation, and inhibition of cell migration in concentration-dependent treatment. Furthermore, G2/M phase arrest, variations in the nuclear morphology, degradation of chromosomal DNA confirmed the ongoing apoptosis in treated HeLa cells. Increase in the expression of cytochrome C and caspase-3 confirmed the involvement of intrinsic mitochondrial pathway regulating the cell death. Also, elevation in reactive oxygen species level and loss of mitochondrial membrane potential signified that compound 4d induced apoptosis in HeLa cells by generating the oxidative stress. Therefore, compound 4d may act as a potent chemotherapeutic agent against human cervical cancer.

Introduction Socioeconomic disparities have been established for conventional cigarette use, but not for electronic cigarettes. This study estimates socioeconomic gradients in exclusive use of conventional cigarettes, electronic cigarettes, and dual use (ie, use of both products) among adults in the United States. Methods Analyses consider nationally representative data on 25- to 54-year-old respondents to the 2014-2016 National Health Interview Surveys (N = 50306). Demographically adjusted seemingly unrelated regression models estimate how two socioeconomic status measures-respondent education and household income-relate to current exclusive use of conventional cigarettes, electronic cigarettes, and dual use. Results Conventional cigarette use exhibits negative education and income gradients, consistent with existing research: -12.9 percentage points (confidence interval [CI]: -14.0, -11.8) if college educated, and -9.5 percentage points (CI: -10.9, -8.1) if household income exceeds 400% of the federal poverty level. These gradients are flatter for dual use (-1.4 [CI: -1.8, -0.9] and -1.9 [CI: -2.5, -1.2]), and statistically insignificant for electronic cigarette use (-0.03 [CI: -0.5, 0.4] and -0.3 [CI: -0.8, -0.2]). Limiting the sample to ever-smokers, higher education is associated with a 0.9 percentage point increase in likelihood of exclusive electronic cigarette use at interview (CI: 0.0, 1.9). Conclusions Education and income gradients in exclusive electronic cigarette use are small and statistically insignificant, contrasting with strong negative gradients in exclusive conventional cigarette use. Furthermore, more educated smokers are more likely to switch to exclusive e-cigarette use than less educated smokers. Such differential switching may exacerbate socioeconomic disparities in smoking-related morbidity and mortality, but lower the burden of tobacco-related disease. Implications Research has not yet established whether socioeconomic disparities in electronic cigarette (e-cigarette) use resemble those observed for conventional cigarettes. This article uses nationally representative data on US adults aged 25-54 to estimate income and education gradients in exclusive use of conventional cigarettes, e-cigarettes, and dual use. Both gradients are steep and negative for conventional cigarette use, but flat and statistically insignificant for e-cigarette use. Repeating the analysis among ever-smokers indicates that more educated smokers are more likely to transition toward exclusive e-cigarette use than less educated smokers. Such differential substitution may exacerbate disparities in smoking-related morbidity and mortality.
