Novel fluorinated 7-hydroxycoumarin derivatives containing an oxime ether moiety: design, synthesis, crystal structure and biological evaluation was written by Wang, Qing-Qing;Zhang, Shu-Guang;Jiao, Jian;Dai, Peng;Zhang, Wei-Hua. And the article was included in Molecules in 2021.Computed Properties of C6H5ClO2 The following contents are mentioned in the article:

A series of fluorinated 7-hydroxycoumarin derivatives containing an oxime ether moiety I [R¹ = H, F; R² = Me, CF₃; R³ = H, Cl; R⁴ = H, Me, Bn, etc.] was designed, synthesized and evaluated for their antifungal activity. All the target compounds were determined by ¹H-NMR, ¹³C-NMR, FTIR and HR-MS spectra. The single-crystal structures of compounds I [R¹ = H, F R² = Me, CF₃, R³ = H, R⁴ = Et, propargyl, butyl] were further confirmed using X-ray diffraction. The preliminary bioassays showed that some of the designed compounds I displayed the promising antifungal activities against Botrytis cinerea (B. cinerea), Alternariasolani (A. solani), Gibberella zeae (G. zeae), Rhizoctorzia solani (R. solani), Colletotrichum orbiculare (C. orbiculare) and Alternaria alternata (A. alternata) were evaluated in vitro. The target compounds I [R¹ = H, F; R² = Me, CF₃, R³ = H, R⁴ = allyl, butyl] exhibited outstanding antifungal activity against B. cinerea at 100μg/mL, with the corresponding inhibition rates reached 90.1 and 85.0%, which were better than the pos. control Osthole (83.6%) and Azoxystrobin (46.5%). The compound I [R¹ = H; R² = CF₃, R³ = Cl, R⁴ = allyl] was identified as the promising fungicide candidate against B. cinerea with the EC₅₀ values of 5.75μg/mL, which was obviously better than Osthole (33.20μg/mL) and Azoxystrobin (64.95μg/mL). The compound I [R¹ = H; R² = CF₃, R³ = Cl, R⁴ = allyl] showed remarkable antifungal activities against R. solani with the EC₅₀ values of 28.96μg/mL, which was better than Osthole (67.18μg/mL) and equivalent to Azoxystrobin (21.34μg/mL). The results provided a significant foundation for the search of novel fluorinated 7-hydroxycoumarin derivatives I with good antifungal activity. This study involved multiple reactions and reactants, such as 4-Chlororesorcinol (cas: 95-88-5Computed Properties of C6H5ClO2).

4-Chlororesorcinol (cas: 95-88-5) belongs to organic chlorides. Organic chlorides are compounds containing a carbon-chlorine bond, which are widely used in the oil field as a wax dissolver. Alkyl chlorides readily react with amines to give substituted amines. Alkyl chlorides are substituted by softer halides such as the iodide in the Finkelstein reaction.Computed Properties of C6H5ClO2

Effect of early-life stress or fluoxetine exposure on later-life conditioned taste aversion learning in Sprague-Dawley rats was written by Ascencio Gutierrez, Verenice;Carrillo, Audrey A.;Boersma, Gretha J.;Tamashiro, Kellie L. K.;Moran, Timothy H.;Iniguez, Sergio D.;Treesukosol, Yada. And the article was included in Neuroscience Letters in 2022.Electric Literature of ClLi The following contents are mentioned in the article:

In rodents, early-life exposure to environmental stress or antidepressant medication treatment has been shown to induce similar long-term consequences on memory- and depression-related behavior in adulthood. To expand on this line of work, we evaluated how juvenile exposure to chronic variable stress (CVS) or the selective serotonin reuptake inhibitor fluoxetine (FLX) influences conditioned taste aversion (CTA) learning in adulthood. To do this, in Experiment 1, we examined how adolescent CVS alone (postnatal day [PND] 35-48), or with prenatal stress (PNS) history (PNS + CVS), influenced the acquisition and extinction of CTA in adult male Sprague Dawley rats. Specifically, at PND70+ (adulthood), rats were presented with 0.15 % saccharin followed by an i.p. (i.p.) injection of lithium chloride (LiCl) to induce visceral malaise. A total of four saccharin (conditioned stimulus) and LiCl (unconditioned stimulus) pairings occurred across the CTA acquisition phase. Next, saccharin was presented without aversive consequences, and intake was measured across consecutive days of the extinction phase. No differences in body weight gain across the exptl. days, rate of CTA acquisition, or extinction of CTA, were observed among the exptl. groups (control, n = 7; CVS, n = 12; PNS + CVS, n = 9). In Experiment 2, we evaluated if early-life FLX exposure alters CTA learning in adulthood. Specifically, adolescent stress naive male and female rats received FLX (0 or 20 mg/kg/i.p) once daily for 15 consecutive days (PND35-49). During antidepressant exposure, FLX decreased body weight gain in both male (n = 7) and female rats (n = 7), when compared to resp. controls (male control, n = 8; female control, n = 8). However, juvenile FLX exposure decreased body weight-gain in adult male, but not female, rats. Lastly, adolescent FLX history had no effect on CTA acquisition or extinction in adulthood (PND70), in neither male nor female rats. Together, the data indicate that juvenile FLX exposure results in a long-term decrease of body weight-gain in a male-specific manner. Yet, independent of sex, neither early-life stress nor FLX exposure alters CTA learning in adulthood. This study involved multiple reactions and reactants, such as Lithium chloride (cas: 7447-41-8Electric Literature of ClLi).

Lithium chloride (cas: 7447-41-8) belongs to organic chlorides. Chlorinated organic compounds are found in nearly every class of biomolecules and natural products including alkaloids, terpenes, amino acids, flavonoids, steroids, and fatty acids. Organochlorine compounds are lipophylic, meaning they are more soluble in fat than in water. This gives them a high tenancy to accumulate in the food chain (biomagnification).Electric Literature of ClLi

Experimental and DFT studies on structure, spectroscopic and thermal properties of N-Methyl-N,N,N-trioctylammonium chloride ionic liquid was written by Assenine, Mohammed Amin;Haddad, Boumediene;Paolone, Annalisa;Brandan, Silvia Antonia;Villemin, Didier;Boumediene, Mostefa;Rahmouni, Mustapha;Bresson, Serge. And the article was included in Journal of Molecular Structure in 2021.SDS of cas: 5137-55-3 The following contents are mentioned in the article:

The [Aliquat⁺][Cl^–] ionic liquid (IL) has been structural and vibrationally characterized combining exptl. FT-IR, FT-Raman and ¹H- and ¹³C-NMR spectroscopies with theor. studies based on the hybrid B3LYP/6-31G* method. The theor. determination of structure of IL in gas phase and aqueous solution by using that level of theory shows three ionic C-H···Cl bonds, as supported by at. Merz-Kollman (MK) charges, bond orders, natural bond orbital (NBO) and atoms in mols. (AIM) calculations Hence, a monodentate coordination between the [Aliquat⁺] cation and Cl anion has been proposed for IL because only one of three ionic C-H···Cl bonds presents higher energy and lower distance. The optimized structure confirmed by NMR measurements has allowed the assignments of 237 normal vibration modes to the bands observed in the IR and Raman spectra with the aid of scaled quantum mech. force field (SQMFF) methodol. and the normal internal coordinates. The effect of Cl in the IL is the shifting of vibration modes corresponding to the CH₂ and CH₃ groups, as compared with the cation. The mapped MEP surface evidence a strong concentration of charges around the chloride anion compatible with nucleophilic sites in these regions while the frontier orbital analyses suggest that IL is most reactive than the cation probably due to the low values of both global electrophilicity and nucleophilicity indexes. The thermal stability shows that [Aliquat+][Cl-] start to decompose just above 200°C. Comparisons between [Aliquat⁺][Cl^–] and [Aliquat⁺][NTf^-2] ILs show that the IL containing chloride is most reactive than the other one while [Aliquat⁺] [NTf^-2] is thermally more stable than [Aliquat⁺][Cl^–]. These results suggest that the properties of an IL containing the [Aliquat⁺] cation are strongly dependent of anion. In addition, the scaled force constants for the [Aliquat⁺][Cl^–] IL are also calculated and compared with the reported for the cation. The Cl anion modifies in notable form the properties of cation. This study involved multiple reactions and reactants, such as N-Methyl-N,N-dioctyloctan-1-aminium chloride (cas: 5137-55-3SDS of cas: 5137-55-3).

Alkali halide force fields: Search for versatility was written by Baranyai, Andras. And the article was included in Journal of Molecular Liquids in 2022.Category: chlorides-buliding-blocks The following contents are mentioned in the article:

In previous papers we were looking for a versatile still simple form of alkali halide force fields. Since the original polarizable version was devised mainly for aqueous solutions, properties of alkali halides as crystals and melts got less attention (P.T Kiss and A. Baranyai, J.Chem.Phys.,141,114501 (2014)). In that paper the non-electrostatic part of alkali halide force fields was formed as a combination of individual repulsion wings, exponentials with two parameters. To obtain correct melting temperature, we left out dipolar polarization as a negligible player in a sym. environment, and massaged the repulsive potentials without moving considerably away from the original form. However, the results were not satisfactory (A. Baranyai, J. Mol. Liquids, 297, 111,762 (2020)). Then we created a different set preserving only the original Gaussian charges with exponential repulsion. Since we wanted to be as accurate as possible, we could obtain potentials for pairs (A. Baranyai, J. Mol. Liquids, 343, 117,575 (2021)). In the present paper we try to re-establish the pairwise combination of repulsions fulfilling the requirement of accurate energy, d. and melting temperature We applied a simpler combination rule for an exponential function, square root both of the pre-exponentials and the arguments. The repulsion of cations was fixed for all combinations. The size difference of cations did not allow covering the entire set with identical anion parameter values. We could create two sep. groups were the anion repulsion was also constant The sodium-potassium and the rubidium-cesium pairs used the same anion parameters. Exceptions are fluorides, we had to use individual anion parameters for K⁺, Rb⁺, and Cs⁺. For lithium the fluoride used the same parameters as in the case of sodium. For other anions of Li⁺, however, they had to use different anion parameters from that of Na⁺. While fluoride deficiency can be attributed to the inadequacy of the form of functions applied, problems of the lithium halides, namely, the nonadditive character of their radii for large anions, is phys. We describe the fitting process and present the results. This study involved multiple reactions and reactants, such as Lithium chloride (cas: 7447-41-8Category: chlorides-buliding-blocks).

Lithium chloride (cas: 7447-41-8) belongs to organic chlorides. Chlorination modifies the physical properties of hydrocarbons in several ways. These compounds are typically denser than water due to the higher atomic weight of chlorine versus hydrogen. Alkanes and aryl alkanes may be chlorinated under free radical conditions, with UV light. However, the extent of chlorination is difficult to control.Category: chlorides-buliding-blocks

Controlled C-H bond activation leads to orthometalation and ring-hydroxylation in Ni(II) and Pd(II) complexes of a common tridentate azophenyl-salicylaldimine ligand was written by Ali, Akram;Bhowmik, Saumitra;Sengupta, Arunava;Mukhopadhyay, Narottam;Mukherjee, Rabindranath. And the article was included in Inorganica Chimica Acta in 2022.Application In Synthesis of Sodium tetrachloropalladate(II) The following contents are mentioned in the article:

Using a common tridentate azophenyl-appended salicylaldimine ligand in its deprotonated form (L⁴)^–, two classical coordination complexes [Ni(L⁴)₂] (1) (Ni^IIO₂N₂N’₂ coordination) and [Pd(L⁴)Cl]•CH₂Cl₂ (2) (Pd^IIONN’Cl coordination), two cyclometalated complexes [M(L^4*)] (M = Ni 3 and Pd 4; M^IIONN’C coordination), and two azophenyl ring-hydroxylated complexes [M(L⁴-O)] (M = Ni 5 and Pd 6; M^IIONN’O’ coordination), obtained due to selective oxidation of M^II-C bond, were synthesized. Complex 1 is paramagnetic (S = 1) but all other complexes are uniformly diamagnetic (S = 0). For 1–6, absorption spectral and redox properties were studied, along with single-crystal structural anal. The regiospecific aryl ring-hydroxylation of M-C bonds in 3 and 4 are achieved due to H₂O₂ and m-CPBA oxidation, resp., affording 5 and 6. Coulometically generated 1-electron oxidation and 1-electron reduction were done on 1–6, and the nature of the resulting species was probed by EPR and absorption spectral studies. While oxidation of 1 and 3 generate Ni(III) species, it is a resonance hybrid between Ni(III) and Ni(II)-O(phenoxyl radical) species for 5. However, 2, 4, and 6 generate ligand radical species. Reduction of 1–6 generates ligand radical species uniformly. D. functional theory (DFT) calculations at the B3LYP level of theory were done to extract information about the electronic structure of the complexes. Time-dependent (TD)-DFT calculations were done to shed light on the origin of observed absorption spectra. Plausible mechanisms are proposed for the observed orthometalation and ring-hydroxylation reactions. This study involved multiple reactions and reactants, such as Sodium tetrachloropalladate(II) (cas: 13820-53-6Application In Synthesis of Sodium tetrachloropalladate(II)).

Sodium tetrachloropalladate(II) (cas: 13820-53-6) belongs to organic chlorides.

Lactobacillus cell envelope-coated nanoparticles for antibiotic delivery against cariogenic biofilm and dental caries was written by Weng, Luting;Wu, Lang;Guo, Rongjuan;Ye, Jiajia;Liang, Wen;Wu, Wei;Chen, Liang;Yang, Deqin. And the article was included in Journal of Nanobiotechnology in 2022.Application of 7447-41-8 The following contents are mentioned in the article:

Due to their prevalence, dental caries ranks first among all diseases endangering human health. Therefore, the prevention of caries is of great significance, as caries have become a serious public health problem worldwide. Currently, using nanoscale drug delivery systems to prevent caries has received increased attention. However, the preventive efficacy of these systems is substantially limited due to the unique physiol. structure of cariogenic biofilms. Thus, novel strategies aimed at combating cariogenic biofilms to improve preventive efficiency against caries are meaningful and very necessary. Herein, inspired by cell membrane coating technol. and Lactobacillus strains, we coated triclosan (TCS)-loaded poly(lactic-co-glycolic acid) (PLGA) nanoparticles (TCS@PLGA-NPs) with an envelope of Lactobacillus (LA/TCS@PLGA-NPs) and investigated their potential as a nanoparticle delivery system against cariogenic biofilms and dental caries. LA/TCS@PLGA-NPs were successfully prepared with favorable properties, including a coated envelope, controllable size, neg. charge, sustained drug-release kinetics and so on. The LA/TCS@PLGA-NPs inherited native properties from the source cell surface, thus the LA/TCS@PLGA-NPs adhered to S. mutans, integrated into the S. mutans biofilm, and interfered with the biofilm formation of S. mutans. The nanoparticles significantly inhibited the activity, biomass and virulence gene expression of S. mutans biofilms in vitro. Addnl., LA/TCS@PLGA-NPs exhibited a long-lasting inhibitory effect on the progression of caries in vivo. The safety performance of the nanoparticles is also favorable. Conclusions: Our findings reveal that the antibiofilm effect of LA/TCS@PLGA-NPs relies not only on the inheritance of native properties from the Lactobacillus cell surface but also on the inhibitory effect on the activity, biomass and virulence of S. mutans biofilms. Thus, these nanoparticles could be considered feasible candidates for a new class of effective drug delivery systems for the prevention of caries. Furthermore, this work provides new insights into cell membrane coating technol. and presents a novel strategy to combat bacterial biofilms and associated infections. This study involved multiple reactions and reactants, such as Lithium chloride (cas: 7447-41-8Application of 7447-41-8).

Lithium chloride (cas: 7447-41-8) belongs to organic chlorides. Organochlorines stimulate the central nervous system and cause convulsions, tremor, nausea, and mental confusion.

Thermal management performance improvement of phase change material for autonomous underwater vehicles’ battery module by optimizing fin design based on quantitative evaluation method was written by Li, Bo;Mao, Zhaoyong;Song, Baowei;Tian, Wenlong;Wang, Yan-Feng;Sunden, Bengt;Lu, Chengyi. And the article was included in International Journal of Energy Research in 2022.COA of Formula: ClLi The following contents are mentioned in the article:

Efficient thermal management of lithium battery modules has become a thorny problem in the development of autonomous underwater vehicles (AUVs), especially under high current discharge. In this article, the fin/phase change material (PCM) composite structure was proposed for AUV’s battery thermal management with consideration of natural convection. The temperature behavior of the battery and the melting behavior of PCM were investigated under different key parameters. In addition, the heat transfer mechanism of the melting process of the PCM was revealed. More importantly, the dimensionless temperature control performance (TCP) factor and the dimensionless heat storage performance (HSP) factor were introduced as new criteria to quant. evaluate the impact of different design parameters on the battery thermal management performance. The results showed that utilizing fins can significantly accelerate the melting of the PCM. Increasing the number of fins can reduce the temperature of the battery and improve the uniformity of the battery temperature distribution. Compared with the pure PCM, the total time required for PCM melting in the fin/PCM battery thermal management unit with different numbers of fins is reduced by at least 11.5%. The decrease of the time of complete PCM melting is not linearly correlated with the length ratio of fins. The fin number of N = 6, length ratio of R = 0.8, and angle between fins of φ = 36° were identified as the optimal parameters of fin/PCM composite structures. The TCP and HSP were enhanced by 38.1% and 4.54%, resp. The conclusions of this work can provide reference for the accurate design of fin/PCM composite structures for the thermal management of AUV batteries. Highlights : The fin/phase change material composite structure was introduced for autonomous underwater vehicles’ battery thermal management. The temperature and melting behavior were investigated with natural convection. The temperature control performance factor and heat storage performance factor were proposed as new evaluation criteria. Temperature deviation index was used to measure the battery temperature uniformity. The performance was enhanced by optimizing the design parameters of fin.

Quaternary ammonium compounds (QACs) are both cationic surfactants and biocidal substances widely used as disinfectants in the food industry. A sensitive and reliable method for the anal. of benzalkonium chlorides (BACs) and dialkyldimethylammonium chlorides (DDACs) has been developed that enables the simultaneous quant. determination of ten quaternary ammonium residues in dairy products below the provisional maximum residue level (MRL), set at 0.1 mg kg^-1. To the best of our knowledge, this method could be the one applicable to milk and to three major processed milk products selected, namely processed or hard pressed cheeses, and whole milk powder. The method comprises solvent extraction using a mixture of acetonitrile and Et acetate, without any further clean-up. Analyses were performed by liquid chromatog. coupled with electrospray tandem mass spectrometry detection (LC-ESI-MS/MS) operating in pos. mode. A C18 anal. column was used for chromatog. separation, with a mobile phase composed of acetonitrile and water both containing 0.3% formic acid; and methanol in the gradient mode. Five deuterated internal standards were added to obtain the most accurate quantification. Extraction recoveries were satisfactory and no matrix effects were observed The method was validated using the total error approach in accordance with the NF V03-110 standard in order to characterize the trueness, repeatability, intermediate precision and anal. limits within the range of 5-150 μg kg^-1 for all matrixes. These performance criteria, calculated by e.noval 3.0 software, were satisfactory and in full accordance with the proposed provisional MRL and with the recommendations in the European Union SANTE/11945/2015 regulatory guidelines. The limit of detection (LOD) was low (<1.9 μg kg^-1) and the limit of quantification (LOQ) ranged from 5 μg kg^-1 to 35 μg kg^-1 for all matrixes depending on the analytes. The validation results proved that the method is suitable for quantifying quaternary ammoniums in foodstuffs from dairy industries at residue levels, and could be used for biocide residues monitoring plans and to measure the exposition consumer to biocides products.

Modeling the solubility of light hydrocarbon gases and their mixture in brine with machine learning and equations of state was written by Mohammadi, Mohammad-Reza;Hadavimoghaddam, Fahimeh;Atashrouz, Saeid;Abedi, Ali;Hemmati-Sarapardeh, Abdolhossein;Mohaddespour, Ahmad.

Knowledge of the solubilities of hydrocarbon components of natural gas in pure water and aqueous electrolyte solutions is important in terms of engineering designs and environmental aspects. In the current work, six machine-learning algorithms, namely Random Forest, Extra Tree, adaptive boosting support vector regression (AdaBoost-SVR), Decision Tree, group method of data handling (GMDH), and genetic programming (GP) were proposed for estimating the solubility of pure and mixture of methane, ethane, propane, and n-butane gases in pure water and aqueous electrolyte systems. To this end, a huge database of hydrocarbon gases solubility (1836 exptl. data points) was prepared over extensive ranges of operating temperature (273-637 K) and pressure (0.051-113.27 MPa). Two different approaches including eight and five inputs were adopted for modeling. Moreover, three famous equations of state (EOSs), namely Peng-Robinson (PR), Valderrama modification of the Patel-Teja (VPT), and Soave-Redlich-Kwong (SRK) were used in comparison with machine-learning models. The AdaBoost-SVR models developed with eight and five inputs outperform the other models proposed in this study, EOSs, and available intelligence models in predicting the solubility of mixtures or/and pure hydrocarbon gases in pure water and aqueous electrolyte systems up to high-pressure and high-temperature conditions having average absolute relative error values of 10.65% and 12.02%, resp., along with determination coefficient of 0.9999. Among the EOSs, VPT, SRK, and PR were ranked in terms of good predictions, resp. Also, the two math. correlations developed with GP and GMDH had satisfactory results and can provide accurate and quick estimates According to sensitivity anal., the temperature and pressure had the greatest effect on hydrocarbon gases’ solubility Addnl., increasing the ionic strength of the solution and the pseudo-critical temperature of the gas mixture decreases the solubilities of hydrocarbon gases in aqueous electrolyte systems. Eventually, the Leverage approach has revealed the validity of the hydrocarbon solubility databank and the high credit of the AdaBoost-SVR models in estimating the solubilities of hydrocarbon gases in aqueous solutions This study involved multiple reactions and reactants, such as Lithium chloride (cas: 7447-41-8Product Details of 7447-41-8).
