Fabrication and characterization of metal organic frameworks/ polyvinyl alcohol cryogel and their application in extraction of non-steroidal anti-inflammatory drugs in water samples was written by Wang, Yudan;Zhang, Yang;Cui, Jianan;Li, Shuo;Yuan, Ming;Wang, Ting;Hu, Qi;Hou, Xiaohong. And the article was included in Analytica Chimica Acta in 2018.HPLC of Formula: 5003-48-5 The following contents are mentioned in the article:

A series of novel MOFs/PVA composite cryogel (MIL-101(Cr)/PVA, MIL-100(Fe)/PVA, ZIF-8(Zn)/PVA, MOF-199(Cu)/PVA and MIL-53(Al)/PVA) were fabricated by using a facile and green freeze-thaw approach for the first time. MIL-101(Cr)/PVA cryogel was selected as a VA-SPE sorbent for extraction of four NSAIDs in environmental water samples. The procedures of condition investigation (synthesis and extraction optimization) and characterization were also performed. And a satisfactory result of methodol. validation was obtained by making use of HPLC-MS/MS. Under the optimum conditions, good sensitivity levels were achieved with the limits of detection between 0.007 and 0.037 μg L^-1, a linearity of 0.10-10 μg L^-1 for phenylbutazone, indomethacin, nimesulide and 0.020-2.0 μg L^-1 for benorilate (r² ≥ 0.9934). The relative recoveries of the target analytes were in the range from 78.44% to 105.7% with relative standard deviation (RSD) from 1.33% to 9.85%. In the extraction process, MIL-101(Cr)/PVA cryogel as a whole sheet outperformed the pristine dispersive MIL-101(Cr) in separation from solvent, and the application of cryogel also simplified the operation procedure. Addnl., the combination of PVA with MOFs might strengthen the interaction ability between the sorbent and analytes. This novel pretreatment method had a variety of merits, such as easy operation, high enrichment efficiency and low matrix effect. It looks forward to further optimization or functionalization and application of these MOFs/PVA cryogel in various disciplines. This study involved multiple reactions and reactants, such as 4-Acetamidophenyl 2-acetoxybenzoate (cas: 5003-48-5HPLC of Formula: 5003-48-5).

4-Acetamidophenyl 2-acetoxybenzoate (cas: 5003-48-5) belongs to esters. Esters are widespread in nature and are widely used in industry. In nature, fats are in general triesters derived from glycerol and fatty acids. Esters are responsible for the aroma of many fruits. 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.HPLC of Formula: 5003-48-5

Hydrocarbon pollution from domestic oil recycling industries in peri-urban soils. Lipid molecular assemblages was written by Alvarez, Ana M.;Carral, Pilar;Hernandez, Zulimar;Almendros, Gonzalo. And the article was included in Journal of Environmental Chemical Engineering in 2016.Product Details of 1731-94-8 The following contents are mentioned in the article:

The impact of continuous inputs of hydrocarbons from domestic waste oil recycling industries and further remediation practices, like inertization (liming and addition of ashes), have been studied in peri-urban soils in Spain in order to monitor the fate and spatial distribution patterns of potentially hazardous organic compounds Phys. and chem. properties of undisturbed soils or contaminated with waste-oil were determined Lipid fractions were extracted using a dichloromethane:methanol mixture and analyzed by gas chromatog.-mass spectrometry (GC/MS) in search for environmental proxies. A pollution gradient (distance to the waste oil spill) was accompanied by the following chromatog. features: (i) the increasing extent of the unresolved ‘hump’ caused by branched/cyclic alkanes with non-biogenic signature, (ii) the depletion of fatty acids and alkanol series, and (iii) the accumulation of phenols and polycyclic hydrocarbons. An increase in the C-preference index (odd-C/even-C numbered homologues) of fatty acids was also detected with an opposed trend in alkane chains. Concerning alkanes and fatty acids chain length, there was a generalized decrease whereas a progressive increase of alien long-chain (>C₂₀) homologues was observed Signature compounds found in waste oil (mainly squalene, steroids and waxes) were almost absent from neighbor soils, either undisturbed or inertized, suggesting the occurrence of rapid biodegradation or condensation processes in the soil matrix probably aided by the remediation practices or by abiotic humification processes. This study involved multiple reactions and reactants, such as Methyl nonadecanoate (cas: 1731-94-8Product Details of 1731-94-8).

Methyl nonadecanoate (cas: 1731-94-8) 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. 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.Product Details of 1731-94-8

Cornstalk liquefaction in methanol/water mixed solvents was written by Zhu, Wei-Wei;Zong, Zhi-Min;Yan, Hong-Lei;Zhao, Yun-Peng;Lu, Yao;Wei, Xian-Yong;Zhang, Dongke. And the article was included in Fuel Processing Technology in 2014.Name: Methyl nonadecanoate The following contents are mentioned in the article:

Cornstalk liquefaction (CSL) in methanol, water or methanol/water mixed solvents was studied at 250-320 °C. Each reaction mixture was separated into extract 1 (E₁, including the solute in filtrate and methanol-extractable portion), extract 2 (E₂, methanol-inextractable but isometric carbon disulfide/acetone-extractable portion) and residue (isometric carbon disulfide/acetone-inextractable portion) by filtration and sequential extraction with methanol and isometric carbon disulfide/acetone mixed solvent. The cornstalk, E₁, E₂ and the residues were analyzed using a Fourier transformation IR spectrometer and each E₁ was analyzed using a gas chromatog./mass spectrometer. The microstructures of the cornstalk and its derived residues were observed with a scanning electron microscope. The results show that methanol and water exhibited a synergic effect on the CSL. The isometric methanol and water mixed solvent was found to be most effective for CSL at 300 °C for 30 min. Under such conditions, the total yield of gases, E₁ and E₂ and the yield of E₁ reached 88.1% and 52.4%, resp. The yields decreased as the temperature or time was further increased, suggesting that some of the extractable species were repolymd. at higher temperatures or for prolonged time. E₁ consisted of hydrocarbons, alkanols, tetrahydrofuranylmethanols, arenols, methoxyalkanes, methoxyarenes, ketones, carboxylic acids, esters, chloromethylbenzenes, nitrogen-containing species and several other species. This study involved multiple reactions and reactants, such as Methyl nonadecanoate (cas: 1731-94-8Name: Methyl nonadecanoate).

Methyl nonadecanoate (cas: 1731-94-8) belongs to esters. Volatile esters with characteristic odours are used in synthetic flavours, perfumes, and cosmetics. Certain volatile esters are used as solvents for lacquers, paints, and varnishes. Because of their lack of hydrogen-bond-donating ability, esters do not self-associate.

Nitrogen starvation induced lipid accumulation by Chlorococcum infusionum (EAU-10) as potential renewable source of lipid for biodiesel production was written by Arguelles, Eldrin DLR.. And the article was included in Journal of Microbiology, Biotechnology and Food Sciences in 2022.Category: esters-buliding-blocks The following contents are mentioned in the article:

Microalgae are organisms effective of accumulating high quantity of industrially important lipids with promising characteristics as an excellent feedstock for biodiesel production This study assess the possibility of using a green microalga, Chlorococcum infusionum (EAU-10) for biodiesel production by evaluating the growth characteristic, lipid yield and fatty acid profile of the microalga cultivated at varying concentrations of nitrogen source (0.375 – 1.50 g L^-1 NaNO₃). High lipid accumulation was observed in nitrogen-starved cultivation condition (0.375 g L^-1 NaNO₃) after 23 days of growth. Maximum biomass concentration of Chlorococcum infusionum (EAU-10) under nitrogen starved condition is 0.577 ± 0.003 g L^-1 with 21.26% oil content per dry weight of algal biomass and lipid productivity of 22.08 mg L^-1 day^-1. Nitrogen starvation caused an increase in the total oil content and a decrease in biomass production of the microalga. Profiling of fatty acids of the obtained algal biodiesel shows Me palmitate (C16:0) and Me nonadecanoate (C19:0) contribute to almost 70% of Chlorococcum infusionum (EAU-10) fatty acid Me esters (FAME) profile. Overall, a total of 74.58% of saturated fatty acid (SAFA) Me ester content is present in the algal lipid, which is exceedingly high in contrast to other similar studies. Anal. of C. infusionum FAME profile in relation to some important fuel properties showed that the algal oil has the potential to produce biodiesel with excellent fuel qualities. This study involved multiple reactions and reactants, such as Methyl nonadecanoate (cas: 1731-94-8Category: esters-buliding-blocks).

Methyl nonadecanoate (cas: 1731-94-8) 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. Esters are more polar than ethers but less polar than alcohols. They participate in hydrogen bonds as hydrogen-bond acceptors, but cannot act as hydrogen-bond donors, unlike their parent alcohols. This ability to participate in hydrogen bonding confers some water-solubility.Category: esters-buliding-blocks

And the article was included in Inorganic and Nano-Metal Chemistry.COA of Formula: C21H44O5 The following contents are mentioned in the article:

The aim of current study was to prepare and optimize the nanostructured lipid carrier (NLC) for transdermal gliclazide (GCZ) delivery. The melt emulsification followed by ultrasonication technique was utilized to prepare GCZ-loaded-NLC. The optimization of NLC was achieved by Box-Behnken design. The surfactant (Tween 20) % (X1), total lipid (glyceryl monostearate + Lauroglycol 90) % (X2), and sonication time (min) (X3) were chosen as independent variables, while particles size (Y1), polydispersity index (Y2), and entrapment efficiency (Y3) were selected as response. Further, the prepared NLC was estimated for in vitro drug release study, ex vivo skin permeation and confocal laser scanning microscopy (CLSM) studies. Results of present study demonstrated that the optimized GCZ loaded NLC formulation presented the particles size, polydispersity index, zeta potential, and entrapment efficiency of 120.4 nm, 0.316, -5.58 mV, and 87.32% resp. The in vitro drug release study indicated drug release of 68.27 ± 2.98% and 45.87 ± 2.85% for GCZ-NLC and conventional GCZ dispersion resp. The GCZ-NLC-Gel formulation exhibited transdermal drug permeation of 76.89 ± 2.52% as compared to conventional gel (45.65 ± 2.79%). The CLSM of rat skin treated with NLC gel exhibited a deeper permeation (35 μm) in comparison to the conventional gel (15 μm). In conclusion, GCZ loaded NLC was successfully optimized using Box-Behnken design that contributed many advantages over conventional formulation and thus demonstrating NLC as propitious carriers for the transdermal GCZ delivery. This study involved multiple reactions and reactants, such as Glyceryl monostearate (cas: 31566-31-1COA of Formula: C21H44O5).

Glyceryl monostearate (cas: 31566-31-1) belongs to esters. Esters are widespread in nature and are widely used in industry. In nature, fats are in general triesters derived from glycerol and fatty acids. Esters are responsible for the aroma of many fruits. Esters contain a carbonyl center, which gives rise to 120° C–C–O and O–C–O angles. Unlike amides, esters are structurally flexible functional groups because rotation about the C–O–C bonds has a low barrier. Their flexibility and low polarity is manifested in their physical properties; they tend to be less rigid (lower melting point) and more volatile (lower boiling point) than the corresponding amides.

High humidity aggravates the severity of arthritis in collagen-induced arthritis mice by upregulating xylitol and L-pyroglutamic acid was written by Wang, Mingzhu;Chen, Jiao;Lin, Xiaoying;Huang, Lin;Li, Haichang;Wen, Chengping;He, Zhixing. And the article was included in Arthritis Research & Therapy in 2021.Category: esters-buliding-blocks The following contents are mentioned in the article:

Humidity was an unfavorable factor for patients with rheumatoid arthritis (RA). RA disease activity was severe in high humidity conditions. However, there is no evidence to demonstrate the effects of humidity on arthritis in the animal experiments and explore its relevant mechanism. Using the DBA/1 mice, this study addressed the effects of a high humidity (80 ± 5%) on arthritis in collagen-induced arthritis (CIA) mice. Then, this study used the gas chromatog.-mass spectrometer (GC-MS) to explore alterations in serum metabolome caused by the high humidity. Furthermore, xylitol and L-pyroglutamic acid, which were both significantly upregulated by the high humidity, were selected to further study their effects on arthritis in the CIA mice. The high humidity (80 ± 5%) could aggravate arthritis variables including increasing arthritis score and swelling, serum autoantibodies (anti-COII and anti-CCP), and proinflammatory cytokines (IL-6, IL-17A, and G-CSF). In addition, the high humidity could cause significant alterations in serum metabolome in the CIA mice. Xylitol and L-pyroglutamic acid were the representative serum metabolites that were significantly upregulated by the high humidity. Further experiments demonstrated that the supplementation of 0.4 mg/mL xylitol in drinking water after inducing the CIA model and 2.0 mg/mL in drinking water before inducing the CIA model could both aggravate arthritis in the CIA mice. These data demonstrated that high humidity was not beneficial for arthritis development and its mechanism might be associated with xylitol and L-pyroglutamic acid. 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. 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. Cyclic esters are called lactones, regardless of whether they are derived from an organic or inorganic acid. One example of an organic lactone is γ-valerolactone.Category: esters-buliding-blocks

Organic chem. pollutants in atm. particulate matter (PM) have a potential toxicity hazard resulting in human responses that vary from no discernible effect to premature death. The formation and sources of PM also affect air quality of metropolitan areas as well as climate change. The new developments and industrial activities in the Middle East, especially Saudi Arabia, are expected to contribute to the natural, regional, and anthropogenic input sources of organic matter (OM). Here we report the occurrence, concentrations and sources of organic tracers, including n-alkanes, polycyclic aromatic hydrocarbons (PAHs), plasticizers, and petroleum biomarkers, in ambient atm. PM from the city of Dhahran, Saudi Arabia. The major compounds were unresolved complex mixtures (UCM) of branched and cyclic hydrocarbons (489 ± 296 ng m^-3), plasticizers (131 ± 119 ng m^-3 for Ph phosphates, 87 ± 42 ng m^-3 for phthalates), n-alkanes (73 ± 53 ng m^-3), hopane biomarkers (11 ± 8 ng m^-3), n-alkanones (6.7 ± 6.3 ng m^-3), PAHs (2.0 ± 2.1 ng m^-3), n-alkanols (1.2 ± 1.2 ng m^-3), sterane biomarkers (0.4 ± 0.3 ng m^-3), and sterols (0.5 ± 0.4 ng m^-3). Obviously, UCM and plasticizers were the major components (56 ± 9% and 26 ± 10% of the total extracts, resp.) in the PM of Dhahran, which might have adverse public health effects. The major sources of this OM are emissions from industrial factories north of the city, plastics and biomass burning, and petroleum product combustion (traffic/refining). This study involved multiple reactions and reactants, such as Methyl nonadecanoate (cas: 1731-94-8Computed Properties of C20H40O2).

Development of trimethyl chitosan coated nanostructure lipid carriers to enhance the brain targeting capacity of ceftriaxone was written by Padhi, Swarupanjali;Mazumder, Rupa;Bisth, Shradha. And the article was included in Journal of Dispersion Science and Technology.Reference of 31566-31-1 The following contents are mentioned in the article:

Cationic nanostructured lipid carriers were devised to improve the biodistribution of the drug in the CNS. Especially, the delivery of antibiotics via uninflamed meninges at various stages of infection is the most challenging part of the treatment regimen. The ceftriaxone loaded nanostructured lipid carriers (NLC-CEFs) were formulated using glyceryl monostearate and capryol90 and the resulting NLC-CEFs were coated with tri-Me chitosan (NLC-CEFs-TMC) to increase the cellular uptake of the drug. The TMC was synthesized from chitosan and its formation was confirmed by XRD, FTIR, DSC, and H1 NMR analyses. The freeze-dried NLC-CEFs and the NLC-CEFs-TMC formed, were evaluated by FTIR, DSC, XRD, SEM, and zeta potential analyses. The rat model was used to study the biodistribution of the drug in brain and confirm the potential delivery of drug in NLC-CEFs-TMC carriers through blood brain barrier. It was found to increase by 10.51 times compared to the drug solution when administered through IV and collected after 8 h. The brain enhancement factor was found to be, 5.86 and 7.95 resp. for NLC-CEFs and NLC-CEFs-TMC collected after 8 h. The brain targeting index was found to be 0.29 ± 0.02, 0.50 ± 0.04 and 0.029 ± 0.007 for NLC-CEFs, NLC-CEFs-TMC, and CEF solution The highest brain targeting index and brain enhancement ratio was achieved by NLC-CEFs-TMC. Success of these lipid dosage forms may be attributed to the lipophilic nature of the NLCs, which is similar to that of meninges and another cause may be the increase in the uptake of cationic NLCs by neg. charged CNS membrane. This study involved multiple reactions and reactants, such as Glyceryl monostearate (cas: 31566-31-1Reference of 31566-31-1).

Glyceryl monostearate (cas: 31566-31-1) belongs to esters. Esters are also usually derived from carboxylic acids.

Fucose-Galactose Polymers Inhibit Cholera Toxin Binding to Fucosylated Structures and Galactose-Dependent Intoxication of Human Enteroids was written by Cervin, Jakob;Boucher, Andrew;Youn, Gyusaang;Bjoerklund, Per;Wallenius, Ville;Mottram, Lynda;Sampson, Nicole S.;Yrlid, Ulf. And the article was included in ACS Infectious Diseases in 2020.Synthetic Route of C16H22O11 The following contents are mentioned in the article:

A promising strategy to limit cholera severity involves blockers mimicking the canonical cholera toxin ligand (CT) ganglioside GM1. However, to date the efficacies of most of these blockers have been evaluated in noncellular systems that lack ligands other than GM1. Importantly, the CT B subunit (CTB) has a noncanonical site that binds fucosylated structures, which in contrast to GM1 are highly expressed in the human intestine. Here we evaluate the capacity of norbornene polymers displaying galactose and/or fucose to block CTB binding to immobilized protein-linked glycan structures and also to primary human and murine small intestine epithelial cells (SI ECs). We show that the binding of CTB to human SI ECs is largely dependent on the noncanonical binding site, and interference with the canonical site has a limited effect while the opposite is observed with murine SI ECs. The galactose-fucose polymer blocks binding to fucosylated glycans but not to GM1. However, the preincubation of CT with the galactose-fucose polymer only partially blocks toxic effects on cultured human enteroid cells, while preincubation with GM1 completely blocks CT-mediated secretion. Our results support a model whereby the binding of fucose to the noncanonical site places CT in close proximity to scarcely expressed galactose receptors such as GM1 to enable binding via the canonical site leading to CT internalization and intoxication. Our finding also highlights the importance of complementing CTB binding studies with functional intoxication studies when assessing the efficacy inhibitors of CT. 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: 604-69-3Synthetic Route of C16H22O11).
