This work aims to construct biocompatible, biodegradable core-cross-linked and insulin-loaded nanoparticles which are sensitive to glucose and release insulin via cleavage of the nanoparticles in a high-concentration blood glucose environment. First, a polyphosphoester-based diblock copolymer (PBYP-g-Gluc)-b-PEEP was prepared via ring-opening copolymerization (ROP) and the copper(I)-catalyzed azide-alkyne cycloaddition (CuAAC) in which PBYP and PEEP represent the polymer segments from 2-(but-3-yn-1-yloxy)-2-oxo-1,3,2-dioxaphospholane and 2-ethoxy-2-oxo-1,3,2-dioxaphospholane, resp., and Gluc comes from 2-azidoethyl-尾-D-glucopyranoside (Gluc-N3) that grafted with PBYP. The structure and mol. weight of the copolymer were characterized by ¹H NMR, ³¹P NMR, GPC, FT-IR, and UV-vis measurements. The amphiphilic copolymer could self-assemble into core-shell uncore-cross-linked nanoparticles (UCCL NPs) in aqueous solutions and form core-cross-linked nanoparticles (CCL NPs) after adding crosslinking agent adipoylamidophenylboronic acid (AAPBA). Dynamic light scattering (DLS) and transmission electron microscopy (TEM) were used to study the self-assembly behavior of the two kinds of NPs and the effect of different Gluc group contents on the size of NPs further to verify the stability and glucose sensitivity of CCL NPs. The ability of NPs to load fluorescein isothiocyanate-labeled insulin (FITC-insulin) and their glucose-triggered release behavior were detected by a fluorescence spectrophotometer. The results of Me thiazolyl tetrazolium (MTT) assay and hemolysis activity experiments showed that the CCL NPs had good biocompatibility. An in vivo hypoglycemic study has shown that FITC-insulin-loaded CCL NPs could reduce blood glucose and have a protective effect on hypoglycemia. This research provides a new method for constructing biodegradable and glucose-sensitive core-cross-linked nanomedicine carriers for controlled insulin release. This study involved multiple reactions and reactants, such as (2S,3R,4S,5R,6R)-6-(Acetoxymethyl)tetrahydro-2H-pyran-2,3,4,5-tetrayl tetraacetate (cas: 604-69-3SDS of cas: 604-69-3).

Metabolic changes through SARS-CoV-2 infection has been reported but not fully comprehended. This metabolic dysregulation affects multiple organs during COVID-19 and its early detection can be used as a prognosis marker of severity. Therefore, we aimed to characterize metabolic and cytokine profile at COVID-19 onset and its relationship with disease severity to identify metabolic profiles predicting disease progression. We performed a retrospective cross-sectional study in 123 COVID-19 patients which were stratified as asymptomatic/mild, moderate and severe according to the highest COVID-19 severity status, and a group of healthy controls. We performed an untargeted plasma metabolic profiling (gas chromatog. and capillary electrophoresis-mass spectrometry (GC and CE-MS)) and cytokine evaluation. After data filtering and identification we observed 105 metabolites dysregulated (66 GC-MS and 40 CE-MS) which shown different expression patterns for each COVID-19 severity status. These metabolites belonged to different metabolic pathways including amino acid, energy, and nitrogen metabolism among others. Severity-specific metabolic dysregulation was observed, as an increased transformation of L-tryptophan into L-kynurenine. Thus, metabolic profiling at hospital admission differentiate between severe and moderate patients in the later phase of worse evolution. Several plasma pro-inflammatory biomarkers showed significant correlation with deregulated metabolites, specially with L-kynurenine and L-tryptophan. Finally, we describe a strong sex-related dysregulation of metabolites, cytokines and chemokines between severe and moderate patients. In conclusion, metabolic profiling of COVID-19 patients at disease onset is a powerful tool to unravel the SARS-CoV-2 mol. pathogenesis. This technique makes it possible to identify metabolic phenoconversion that predicts disease progression and explains the pronounced pathogenesis differences between sexes.

Molecular Simulations of Surfactant Adsorption on Iron Oxide from Hydrocarbon Solvents was written by Acero, Pablo Navarro;Mohr, Stephan;Bernabei, Marco;Fernandez, Carlos;Dominguez, Beatriz;Ewen, James P.. And the article was included in Langmuir in 2021.Category: esters-buliding-blocks The following contents are mentioned in the article:

The performance of organic friction modifiers (OFMs) depends on their ability to adsorb onto surfaces and form protective monolayers. Understanding the relationship between OFM concentration in the base oil and the resulting surface coverage is important for improving lubricant formulations. Here, we use mol. dynamics (MD) simulations to study the adsorption of three OFMs: stearic acid (SA), glycerol monoostearate (GMS), and glycerol monooleate (GMO), onto a hematite surface from two hydrocarbon solvents: n-hexadecane and poly-伪-olefin (PAO). We calculate the potential of mean force of the adsorption process using the adaptive biasing force algorithm and the adsorption strength increases in the order: SA < GMS < GMO. We estimate the min. area occupied by OFM mols. on the surface using annealing MD simulations and obtained a similar hard-disk area for GMS and GMO, but a lower value for SA. Using the MD results, we determine the adsorption isotherms using the mol. thermodn. theory (MTT), which agree well with one previous exptl. data set for SA on hematite. For two other exptl. data sets for SA, lateral interactions between surfactant mols. need to be accounted for within the MTT framework. SA forms monolayers with lower surface coverage than GMO and GMS at low concentrations, but also has the highest plateau coverage. We validate the adsorption energies from the MD simulations using high frequency reciprocating rig friction experiments with different concentrations of the OFMs in PAO. For OFMs with saturated tailgroups (SA and GMS), we obtain good agreement between the simulations and the experiments The results deviate for OFMs containing Z-unsaturated tailgroups (GMO), due to the addnl. steric hindrance, which is not accounted for in the current simualtion framework. This study demonstrates that MD simulations, alongside MTT, are an accurate and efficient tool to predict adsorption isotherms at solid-liquid interfaces. This study involved multiple reactions and reactants, such as Glyceryl monostearate (cas: 31566-31-1Category: esters-buliding-blocks).

Glyceryl monostearate (cas: 31566-31-1) belongs to esters. Carboxylic acid esters of low molecular weight are colourless, volatile liquids with pleasant odours, slightly soluble in water. Many esters have the potential for conformational isomerism, but they tend to adopt an s-cis (or Z) conformation rather than the s-trans (or E) alternative, due to a combination of hyperconjugation and dipole minimization effects. The preference for the Z conformation is influenced by the nature of the substituents and solvent, if present. Lactones with small rings are restricted to the s-trans (i.e. E) conformation due to their cyclic structure.Category: esters-buliding-blocks

Preparation of deer oil powder and its effect on acute gastric mucosal injury in rats was written by Xia, Yun-Shi;Li, Zhi-Man;Liu, Chang;Mu, Rui;Bo, Pan-Pan;Wang, Zi;Sun, Yin-Shi. And the article was included in Journal of Food Biochemistry in 2022.Synthetic Route of C21H44O5 The following contents are mentioned in the article:

In this paper, deer oil was used as a raw material to prepare deer oil powder by microencapsulation technol. to study the potential protective activity of deer oil powder on ethanol-induced acute gastric mucosal injury in rats. The results show that the best process for preparing deer oil powder is: the solids account for 25% of the system content, the wall material Whey Milk Protein Isolate-Maltodextrin ratio is 1:5, the Sodium Stearyl Lactate-Glycerides of Monostearate and Distearate compound emulsifier content is 0.8%, the ratio is 1:1, and the deer oil accounts for 30% of the solid content, and the spray drying inlet temperature is 180掳C. Deer oil powder can reduce total stomach injury, gastric mucosal congestion area, and injury score index. Without affecting the blood lipid level, it can reduce the content of Myeloperoxidase, enhance the activity of Superoxide Dismutase and Glutathione Peroxidase, and has good antioxidant activity. Enhance the expression of defense factors Estradiol, Epidermal Growth Factor, and Somatostatin. At the same time, it reduces the levels of Interleukin-1尾 and Interleukin-6 pro-inflammatory cytokines in gastric tissue and enhances the expression of anti-inflammatory factors Interleukin-4 and Interleukin-10. These results indicate that the gastric protection mechanism of deer oil powder may be related to the enhancement of mucosal defense factors, inhibition of inflammation, and oxidative stress. Practical applications : This study screened the optimal formula for preparing microencapsulated deer oil powder and proved for the first time that deer oil powder has a strong gastroprotective effect on ethanol-induced acute gastric injury in rats. The gastric protective mechanism of deer oil powder is mainly to reduce oxidative stress, inflammatory cytokine accumulation and to increase the content of defense factors. Therefore, deer oil powder can be used as a new source of gastric treatment drugs. This study involved multiple reactions and reactants, such as Glyceryl monostearate (cas: 31566-31-1Synthetic Route of C21H44O5).

Glyceryl monostearate (cas: 31566-31-1) belongs to esters. Esters perform as high-grade solvents for a broad array of plastics, plasticizers, resins, and lacquers, and are one of the largest classes of synthetic lubricants on the commercial market. Polyesters are important plastics, with monomers linked by ester moieties. Because of their lack of hydrogen-bond-donating ability, esters do not self-associate. Consequently, esters are more volatile than carboxylic acids of similar molecular weight.Synthetic Route of C21H44O5

Evaluation of the anticoccidial effect of traditional medicinal plants, Cinnamomum verum bark and Rumex nervosus leaves in experimentally infected broiler chickens with Eimeria tenella was written by Qaid, Mohammed M.;Mansour, Lamjed;Al-Garadi, Maged A.;Alqhtani, Abdulmohsen H.;Al-abdullatif, Abdulaziz A.;Qasem, Mahmood A.;Murshed, Mutee A.. And the article was included in Italian Journal of Animal Science in 2022.Application In Synthesis of Methyl nonadecanoate The following contents are mentioned in the article:

Rumex nervosus leaves (RNL) and Cinnamomum verum bark (CNB), phytogenic herbs, have received much attention in recent years for their antimicrobial properties; however, there is limited knowledge about their potential anticoccidial functions. The prophylactic effects of RNL and CNB were compared with salinomycin, a standard synthetic anticoccidial agent, in broilers exptl. infected with Eimeria tenella (E. tenella). One-day-old broiler chicks (n = 225) were randomly divided into nine groups. Birds were either fed a basal diet containing 1, 3, or 5 g RNL or 2, 4, or 6 g CNB/kg feed, or treated with salinomycin within the basal diet, or the infected (IUT) or non-infected (UUT) groups were fed a basal diet only. Birds infected (n = 25 bird/group) with 40,000 sporulated E. tenella oocysts/bird at d 21 except UUT. Bodweight gain (BWG) and feed conversion ratio (FCR) were significantly (p < .05) lower in IUT compared to UUT. On day 7 post-infection (DPI), birds treated with RNL, CNB, or salinomycin had fewer lesions in the caeca and a lower oocyst value, and a higher oocyst reduction rate in the faeces than birds in the IUT. Although RNL was not able to reduce weight loss caused by coccidiosis, CNB at 6 g improved FCR and production efficiency index (PEI) at 7 DPI compared to the infected groups. In conclusion, RNL at 5 g and CNB at 6 g have moderate anti-coccidial activity and could be used to treat poultry coccidiosis in the field. However, more research is needed to identify active ingredients that make it effective compared to com. available drugs. HIGHLIGHTSPhytogenic feed additives prevented weight loss and caecum pathol. in broiler chickens at risk of coccidiosis. Rumex nervosus leaves and Cinnamomum verum bark had similar effects to the coccidiostat salinomycin at high doses. Traditional medicinal plants are potential alternatives to pharmaceutical coccidiostats to promote the health and growth of broiler chickens.

Jr. And the article was included in Journal of Chemical Thermodynamics in 2021.Safety of 4-Acetamidophenyl 2-acetoxybenzoate The following contents are mentioned in the article:

This contribution was devoted to the equilibrium solubility profile, solute-solvent and solvent-solvent interactions and solvation behavior of benorilate in aqueous binary mixtures of the cosolvent (i.e. ethanol, N-methyl-2-pyrrolidinone (NMP), isopropanol and N,N-dimethylformamide (DMF)) together with several math. associations All experiments were conducted by a shake-flask method under ambient pressure of 101.2 kPa from 278.15 to 318.15 K. The maximum scale of equilibrium benorilate solubility in neat cosolvent at T = 318.15 K; while the min. one was observed in pure water at 278.15 K. The equilibrium benorilate solubility was analyzed by using the Hildebrand and Hansen solubility parameters. Various solubility models including Jouyban-Acree-van’t Hoff, modified Wilson, Jouyban-Acree and mixture response surface (MRS) were employed to fit the mole fraction solubility data, attaining the average relative deviations (RAD) of no more than 9.62%. The relative significance of mol. interactions of solvent-solvent and solute-solvent species upon the equilibrium solubility of benorilate at 298.15 K analyzed through the linear solvation energy relationships specified that the dominant contributions to solubility variation were observed as solubility parameter and dipolarity-polarizability of systems. The solubility data was investigated by means of the extended Hildebrand solubility approach gaining relative average deviation values of no higher than 3.71%. In terms of solution properties, a quant. anal. on preferential solvation of benorilate was conducted by inverse Kirkwood-Buff integrals method. The preferential solvation parameters for neat cosolvent were recorded as pos. in cosolvent-rich and intermediate regions in solutions, suggesting that benorilate was preferentially solvated by the cosolvents. In the above composition regions, it is conjectured that benorilate is performing as a Lewis acid with the cosolvent mols.

Characterization of the composition of plant protection products in different formulation types employing suspect screening and unknown approaches was written by Hergueta-Castillo, Maria Elena;Lopez-Ruiz, Rosalia;Garrido Frenich, Antonia;Romero-Gonzalez, Roberto. And the article was included in Journal of the Science of Food and Agriculture in 2022.Safety of Glyceryl monostearate The following contents are mentioned in the article:

Plant protection products (PPPs) are used extensively in agriculture to control crops. These PPPs, which may be found in different types of formulations, are composed of a designated pesticide (active principle) and other inactive ingredients as co-formulants. They perform specific functions in the formulation, as solvents, preservatives or antifreeze agents, among others. A research technique based on ultra-high-performance liquid chromatog. (UHPLC) coupled to a Quadrupole-Orbitrap mass analyzer was successfully applied to characterize the composition of six different PPPs in terms of the presence of co-formulants and types of formulations: emulsifiable concentrate (EC), emulsion in water (EW), suspension concentrate and water-dispersible granule. These PPPs (FLINT MAX, MASSOCUR 12.5 EC, IMPACT EVO, TOPAS, LATINO and IMPALA STAR) had antifungal activity, containing one triazole compound as active principle (tebuconazole, penconazole, myclobutanil, flutriafol or fenbuconazole, resp.). Non-targeted approaches, applying suspect and unknown anal., were carried out and ten compounds were identified as potential co-formulants. Six (glyceryl monostearate, 1-monopalmitin, DMSO, N,N-dimethyldecanamide, hexaethylene glycol and 1,2-benzisothiazol-3(2H)-one) were confirmed by injecting anal. standards Finally, these compounds were quantified in the PPPs. The current study allowed for detecting co-formulants in a wide range of concentrations, between 0.04 (DMSO) and 19.00 g L-1 (glyceryl monostearate), highlighting the feasibility of the proposed anal. methodol. Moreover, notable differences among the types of formulations of PPPs were achieved, revealing that EC and EW were the formulations that contained the largest number of co-formulants (four out of six detected compounds). 2022 The Authors.

Process dynamic investigations and emission analyses of biodiesel produced using Sr-Ce mixed metal oxide heterogeneous catalyst was written by Banerjee, Sushmita;Sahani, Shalini;Chandra Sharma, Yogesh. And the article was included in Journal of Environmental Management in 2019.Electric Literature of C20H40O2 The following contents are mentioned in the article:

The present study explores the feasibility of Sr-Ce based mixed metal oxides for its performance in transesterification reaction of waste cooking oil. The catalyst synthesis was carried out through gel combustion route and was characterized through several techniques including thermal anal. (TGA-DTA), X-ray diffraction (XRD), attenuated total reflectance based Fourier transform IR spectroscopy (ATR-FTIR), high resolution SEM (HR-SEM) assisted with EDX, BET sp. surface area and Hammett indicator basicity. The enhanced activity of the catalyst was investigated at pH 7.0 with Sr-Ce at. ratio of 3:1 at 900掳C of calcination temperature Influences of various process parameters on transesterification efficiency were carefully investigated. The exptl. results demonstrated that maximum transesterification efficacy of 99.5% was achieved under optimized reaction conditions with catalyst dose of 2.0 wt%, oil-to-methanol ratio 1:14, reaction time 120 min, reaction temperature 65掳C and stirring speed of 700 rpm. For better interpretation of the process, the reaction rate was computed by employing pseudo-first and pseudo-second order kinetics model at varying reaction temperature (50掳C-75掳C). The transesterification data agreed well with pseudo-first order model with highest rate constant value of 2.5 脳 10^-3 min^-1 was evaluated at 65掳C. Activation energy and frequency of the reaction was quantified from the Arrhenius expression as 17.04 kJ/mol and 9.92 min^-1, resp. Thermodn. anal. of the reaction system suggests that the transesterification of the waste cooking oil followed endergonic reaction pathway. Synthesis of biodiesel was ascertained from the H¹ -NMR and FTIR anal. of the transesterified product, further, the physicochem. properties of the biodiesel were also compared with that of diesel fuel and the resultant values were found to be within ASTM limits. Reusability study was also conducted and it indicated that the catalyst can be easily regenerated and could be effectively reused up to four runs.

Design and Comparative Evaluation of Vancomycin HCl-Loaded Rosin-Based In Situ Forming Gel and Microparticles was written by Chuenbarn, Tiraniti;Sirirak, Jitnapa;Tuntarawongsa, Sarun;Okonogi, Siriporn;Phaechamud, Thawatchai. And the article was included in Gels in 2022.Name: Glyceryl monostearate The following contents are mentioned in the article:

Vancomycin hydrochloride (HCl) is a glycopeptide antibiotic used to treat serious or life-threatening infections, and it reduces plaque scores and gingivitis in periodontal patients. In this study, vancomycin HCl was incorporated into rosin in situ forming gel (ISG) and rosin in situ forming microparticles (ISM) to generate a local drug delivery system to treat periodontal disease. The phys. properties of the ISG and ISM were measured, including pH, viscosity, injectability, adhesion properties, in-vitro transformation, and drug release. Moreover, the effectiveness of antimicrobial activity was tested using the agar-cup diffusion method against Staphylococcus aureus, Streptococcus mutans, Porphyromonas gingivalis, and Escherichia coli. Vancomycin HCl-loaded rosin-based ISG and ISM had a pH value in the range of 5.02-6.48 and exhibited the ease of injection with an injection force of less than 20 N. Addnl., the lubricity effect of the external oil phase of ISM promoted less work of injection than ISG and 40-60% rosin-based ISM showed good emulsion stability. The droplet size of emulsions containing 40%, 50%, and 60% rosin was 98.48 卤 16.11, 125.55 卤 4.75, and 137.80 卤 16.8渭m, resp. Their obtained microparticles were significantly smaller in diameter, 78.63 卤 12.97, 93.81 卤 10.53, and 118.32 卤 15.61渭m, resp., because the particles shrank due to the solvent loss from solvent exchange. Moreover, increasing the concentration of rosin increased the size of microparticles. After phase transformation, all formulations had better plasticity properties than elasticity; therefore, they could easily adapt to the specific shape of a patient’s gum cavity. Both developed ISG and ISM presented inhibition zones against S. mutans and P. gingivalis, with ISG presenting significantly more effectively against these two microbes (p < 0.05). The vancomycin HCl-loaded rosin ISG and ISM delayed drug release for 7 days with efficient antimicrobial activities; thus, they exhibit potential as the drug delivery systems for periodontitis treatment.

Search for Novel Lead Inhibitors of Yeast Cytochrome bc1, from Drugbank and COCONUT was written by Jovic, Ozren;Smuc, Tomislav. And the article was included in Molecules in 2021.HPLC of Formula: 5003-48-5 The following contents are mentioned in the article:

In this work we introduce a novel filtering and mol. modeling pipeline based on a fingerprint and descriptor similarity procedure, coupled with mol. docking and mol. dynamics (MD), to select potential novel quoinone outside inhibitors (QoI) of cytochrome bc1 with the aim of determining the same or different chromophores to usual. The study was carried out using the yeast cytochrome bc1 complex with its docked ligand (stigmatellin), using all the fungicides from FRAC code C3 mode of action, 8617 Drugbank compounds and 401,624 COCONUT compounds The introduced drug repurposing pipeline consists of compound similarity with C3 fungicides and mol. docking (MD) simulations with final QM/MM binding energy determination, while aiming for potential novel chromophores and perserving at least an amide (R1HN(C=O)R2) or ester functional group of almost all up to date C3 fungicides. 3D descriptors used for a similarity test were based on the 280 most stable Padel descriptors. Hit compounds that passed fingerprint and 3D descriptor similarity condition and had either an amide or an ester group were submitted to docking where they further had to satisfy both Chemscore fitness and specific conformation constraints. This rigorous selection resulted in a very limited number of candidates that were forwarded to MD simulations and QM/MM binding affinity estimations by the ORCA DFT program. In this final step, stringent criteria based on (a) sufficiently high frequency of H-bonds; (b) high interaction energy between protein and ligand through the whole MD trajectory; and (c) high enough QM/MM binding energy scores were applied to further filter candidate inhibitors. This elaborate search pipeline led finaly to four Drugbank synthetic lead compounds (DrugBank) and seven natural (COCONUT database) lead compounds-tentative new inhibitors of cytochrome bc1. These eleven lead compounds were addnl. validated through a comparison of MM/PBSA free binding energy for new leads against those obtatined for 19 QoIs.
