We report herein the synthesis of a polymeric photosensitizer and its application in aerobic photooxidative hydroxylation of boronic acids. The polymeric photosensitizer was synthesized by the condensation of anthraquinone-2-carbonyl chloride (AQ-2-COCl) with poly (2-hydroxyethyl methacrylate) (PHEMA). The photo-oxidative hydroxylation of boronic acids using anthraquinone-containing-poly (2-hydroxyethyl methacrylate) (AQ-PHEMA) was then explored and shown to exhibit high efficiency and broad scope. Moreover, AQ-PHEMA could be easily recovered and reused for more than 20 times without significant loss of the catalytic activity.

A three-descriptor quantitative structure-activity/toxicity relationship (QSAR/QSTR) model was developed for the skin permeability of a sufficiently large data set consisting of 274 compounds, by applying support vector machine (SVM) together with genetic algorithm. The optimal SVM model possesses the coefficient of determination R-2 of 0.946 and root mean square (rms) error of 0.253 for the training set of 139 compounds; and a R-2 of 0.872 and rms of 0.302 for the test set of 135 compounds. Compared with other models reported in the literature, our SVM model shows better statistical performance in a model that deals with more samples in the test set. Therefore, applying a SVM algorithm to develop a nonlinear QSAR model for skin permeability was achieved.

I found the field of Environmental Sciences & Ecology very interesting. Saw the article Identification of 3-(trifluoromethyl)phenol as the malodorous compound in a pollution incident in the water supply in Catalonia (NE Spain) published in 2019. Safety of 3-(Trifluoromethyl)phenol, Reprint Addresses Quintana, J (corresponding author), Aigues Barcelona, Empresa Metropolitana Gestio Cicle Integral Aigua, Gen Batet 1-7, Barcelona 08028, Spain.. The CAS is 98-17-9. Through research, I have a further understanding and discovery of 3-(Trifluoromethyl)phenol

A study of organic compounds that caused a serious taste and odor episode of water supply in two residential areas in Catalonia (N.E. Spain) was carried out. Sweet and paint/solvent odor were the main descriptors used by consumers. Some cases of sickness and nausea were also associated with drinking water consumption by the consumers. Closed-loop stripping analysis (CLSA) combined with sensory gas chromatography and gas chromatography mass spectrometry detection were used to study the problem. As a result, 3-(trifluoromethyl)phenol (CAS number 98-17-9) was for the first time identified as a responsible of an odor incident in drinking water. Concentration levels of this compound were up to 17,000ng/L in groundwater and up to 600ng/L in distributed water. Odor threshold in water for 3-(trifluoromethyl)phenol was determined as 13ng/L (45 degrees C).

The Fe3O4/ZnO/MWCNTs magnetic nanocomposites as a high-performance organomettalic catalyst were employed for the preparation of new chromeno pyrano [2,3-d]thiazins derivatives in high yields via the five component reactions of 2-hydroxyacetophenone or its derivatives, dimethyl carbonate, aldehydes, malononitrile or ethyl 2-cyanoacetate, and isothiocyanates in ionic liquid at room temperature. The Fe3O4/ZnO/MWCNTs MNCs were synthesized using ionic liquid [OMIM]Br as a stabilizer and soft template. As well Fe3O4/ZnO/MWCNTs MNCs show a good improvement in the yield of the product and showed significant reusable ability. Due to having NH group in synthesized compounds, we investigate antioxidant property of some synthesized compounds by diphenyl-picrylhydrazine (DPPH) radical trapping and power of ferric reduction experiment. Furthermore, the disk diffusion test on Gram-positive and Gram-negative bacteria is utilized for investigation of antimicrobial activity of some chromeno pyrano [2,3-d]thiazins. The achieved outcomes of this experiment demonstrate that these synthesized compounds could prevent from growth of bacteria. Short time of reaction, high yields of product, easy separation of catalyst, and products are some benefits of this process.

Two new series of diethyl 2-[2-(substituted-2-oxo-1,2-dihydroquinolin-4-yl)hydrazono]-succinates 6a-g and 1-(2-oxo-1,2-dihydroquinolin-4-yl)-1H-pyrazoles 7a-f have been designed and synthesized. The structures of the synthesized compounds were proved by IR, mass, NMR (2D) spectra and elemental analyses. The target compounds were evaluated for their in vitro cytotoxic activity against 60 cancer cell lines according to NCI protocol. Consequently, seven compounds were further examined against the most sensitive cell lines, leukemia CCRFCEM, and MOLT-4. 5-Amino-1-(6-bromo-2-oxo-1,2-dihydroquinolin-4-yl)-1H-pyrazole-3,4-dicarbonitrile (7f) was the most active product, with IC50= 1.35 uM and 2.42 uM against MOLT-4 and CCRF-CEM, respectively. Also, it showed a remarkable inhibitory activity compared to erlotinib on the EGFR TK with IC50 = 247.14 nM and 208.42 nM, respectively. Cell cycle analysis of MOLT-4 cells treated with 7f showed cell cycle arrest at G2/M phase (supported by Caspases, BAX and Bcl-2 studies) with a significant pro-apoptotic activity as indicated by annexin V-FITC staining. Moreover, the docking study indicated that both the pyrazole moiety and the quinolin-2-one ring showed good fitting into EGFR (PDB code: 1M17). In order to interpret SAR of the designed compounds, and provide a basis for further optimization, molecular docking of the synthesized compounds to known EGFR inhibitors was performed. The study illustrated the effect of several factors on the compounds’ activity.

Carbohydrazones are compounds that are increasingly studied due to their wide potential biological activity. Monocarbohydrazones (mCHs), as one of the carbohydrazone derivatives, so far have been poorly investigated. For a more detailed study, in this paper, eighteen compounds of monocarbohydrazones (eight known and ten newly synthesized derivatives) were synthesized and characterized using NMR and IR spectroscopy. As carbohydrazones show E/Z isomerization caused by the presence of the imino group, some of the synthesized mCHs are in the form of a mixture of these two isomers. The effects of specific and nonspecific solvent-solute interactions on the UV absorption maxima shifts were evaluated using linear free energy relationships principles, i.e., using Kamlet-Taft’s and Catalan’s models. For more information about interactions between dissolved substance and the surrounding medium, correlations have been made with Hansen’s solubility parameters. The influence of the structure on the spectral behavior of the compounds tested was interpreted using Hammett’s equation. Experimentally obtained physicochemical properties of mCHs were compared to and confirmed with computational methods that included TD-DFT calculations and MP2 geometry optimizations.

Quality Control of Benzyl Alcohol. Cho, CW; Zhao, Y; Yun, YS in [Cho, Chul-Woong; Zhao, Yufeng; Yun, Yeoung-Sang] Chonbuk Natl Univ, Sch Chem Engn, 567 Baekje Dearo, Jeonju 561756, Chonbuk, South Korea published QSAR modelling for predicting adsorption of neutral, cationic, and anionic pharmaceuticals and other neutral compounds to microalgae Chlorella vulgaris in aquatic environment in 2019, Cited 43.

Environmental fate or transport of pharmaceutical waste depends on the adsorptive interactions of pharmaceuticals with various environmental phases e.g. soil, sediment, microalgae, and bacteria etc. Therefore, it is important to understand these adsorptive interactions. As part of the study, we studied the adsorptive interaction of 30 chemicals with microalgae, i.e. Chlorella vulgaris, because it is ubiquitous and its surface area occupies a high proportion in aquatic environments. For this study, isotherms between C vulgaris and 30 micropollutants in neutral and ionic forms (i.e. 15 cations, 5 anions, and 10 neutrals) were experimentally measured, and their adsorptive affinities were then theoretically predicted based on the concept of the linear free energy relationship. For modeling, the dataset was divided into a training set and a test set, where the training set was used for model development and the test set was performed for model validation. This process was repeated ten times. Finally, we suggested one model which has high predictability in R-2 of 0.96 and standard error (SE) of 0.17 log unit for the training set, R-2 of 0.818 and SE = 0.217 log unit for the test set, and R-2 of 0.926 and SE of 0.169 log unit for the total dataset. Moreover, it was found that dispersive force, H-bond basicity, molecular volume, and electrostatic interaction of anion significantly contribute to the model developed based on the entire dataset. Here, dispersive and hydrophobic interactions (proportional to the magnitude of molecular size) are main attractive forces, while the rest cases are repulsive. In addition, it was found that the adsorption property of the surface of C. vulgaris differs from those of Gram negative bacteria Escherichia coli and dissolved organic matters in an aquatic environment.

The Name is Benzyl Alcohol. Through research, I have a further understanding and discovery of 100-51-6.

ZnWO4 catalysts are brilliant in the field of photocatalysis due to their excellent chemical stability and optical properties. In this work, we prepared pure ZnWO4 by a hydrothermal method, evaluated its ability to degrade toluene and elucidated the photocatalytic reaction mechanism. The results showed that ZnWO4 had excellent catalytic activity and stability. Combining the ESR spectroscopy spectra and DFT calculation results, ZnWO4 was found to adsorb a large amount of O-2 and H2O, and activate them to produce active radicals participating in the oxidation reaction of toluene. The reactions to form benzyl alcohol and benzoic acid could be carried out spontaneously based on the Gibbs free energy calculation results and in situ DRIFTS spectra, which indicated that benzaldehyde can be easily converted to benzoic acid. The ring opening reaction is more likely to be carried out on benzoic acid. The findings of this work can extend the application of ZnWO4 materials and the understanding of the mechanism of photocatalytic degradation of toluene.

The dimeric lindenane sesquiterpenoids are mainly isolated from the plants of Chloranthaceae family. Structurally, they have a crowded molecular scaffold decorated with more than 11 stereogenic centers. Here we report divergent syntheses of eight dimeric lindenane sesquiterpenoids, shizukaols A, C, D, I, chlorajaponilide C, multistalide B, sarcandrolide J and sarglabolide I. In particular, we present a unified dimerization strategy utilizing a basemediated thermal [4 + 2] cycloaddition between a common furyl diene, generated in situ, and various types of dienophiles. Accordingly, all the three types of lindenane [4 + 2] dimers with versatile biological activities are accessible, which would stimulate future probing of their pharmaceutical potential.
