Alkyl di-/tri-/tetraoxyethyl β-D-xylopyranosides as derivatives of alkyl xylosides are a class of non-ionic sugar-based surfactants. They were stereoselectively synthesized by the Helferich method. Their properties including hydrophilic-lipophilic balance number, water solubility, surface property, foam property, emulsifying property, and thermotropic liquid crystal property were mainly investigated. The results showed that their water solubility decreased with increasing the alkyl chain length and increasing the number of the oligooxyethyl fragment. The critical micelle concentration had a monotonous decreasing trend with increasing the alkyl chain length. Nonyl di-/tri-/tetraoxyethyl β-D-xylopyranosides [-(OCH₂CH₂)_m-, where m = 2, 3, and 4] exhibited the most excellent foaming ability and foam stability. In the n-octane/water system, dodecyl tetraoxyethyl β-D-xylopyranosides and tetradecyl tetraoxyethyl β-D-xylopyranosides had the strongest emulsion ability. In addition, some alkyl di-/tri-/tetraoxyethyl β-D-xylopyranosides had thermotropic liquid crystal properties. Such sugar-based surfactants, alkyl di-/tri-/tetraoxyethyl β-D-xylopyranosides, will be expected to develop for a variety of practical application. This study involved multiple reactions and reactants, such as 2-(2-(Hexyloxy)ethoxy)ethanol (cas: 112-59-4Computed Properties of C10H22O3).

2-(2-(Hexyloxy)ethoxy)ethanol (cas: 112-59-4) belongs to ethers. 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. Esterification is the general name for a chemical reaction in which two reactants (typically an alcohol and an acid) form an ester as the reaction product. Esters are common in organic chemistry and biological materials.Computed Properties of C10H22O3

Cleaning properties of single-phase hydrocarbon-based microemulsion systems was written by Klier, J.;Suarez, R. S.;Green, D. P.;Kumar, A. M.;Hoffman, M.;Tucker, C. J.;Landes, B.;Redwine, D.. And the article was included in Journal of the American Oil Chemists’ Society in 1997.Computed Properties of C10H22O3 The following contents are mentioned in the article:

Single-phase hydrocarbon-based microemulsions with low volatile organic carbon levels were evaluated in terms of solvent-like cleaning properties, and can help meet regulatory requirements. The rheol. and petroleum jelly solubilization properties of model microemulsion systems that contained linear alkylbenzenesulfonate surfactant, diethylene glycol monohexyl ether co-surfactant, and equal volumes of hydrocarbon solvent and water were evaluated as a function of microemulsion structure and composition The hydrocarbons were linear alkanes C₅ to ₁₂. Single-phase microemulsions with low surfactant contents and broad formulation flexibility were obtained through the use of efficient anionic surfactants and low NaCl electrolyte levels. The microemulsion structure was advanced from solvent-continuous to water-continuous by varying the solvent alkane carbon number or the electrolyte content, whereas the liquid crystal content was controlled via cosurfactant concentration Both microemulsion structure and viscosity influenced solubilization rates. Low-viscosity, solvent-continuous microemulsions showed solubilization rates comparable to those found with solvent-based systems, while water-continuous microemulsions showed relatively poor solubilization rates. Microemulsions containing dispersed liquid crystals exhibited high viscosity and low solubilization rates. This study involved multiple reactions and reactants, such as 2-(2-(Hexyloxy)ethoxy)ethanol (cas: 112-59-4Computed Properties of C10H22O3).

2-(2-(Hexyloxy)ethoxy)ethanol (cas: 112-59-4) belongs to ethers. 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 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.Computed Properties of C10H22O3

Chagas disease (CD) is a neglected protozoan infection caused by Trypanosoma cruzi, which affects about 7 million people worldwide. There are two available drugs in therapeutics, however, they lack effectiveness for the chronic stage-characterized mainly by cardiac (i.e., cardiomyopathy) and digestive manifestations (i.e., megaesophagus, megacolon). Due to the involvement of the immuno-inflammatory pathways in the disease′s progress, compounds exhibiting antioxidant and anti-inflammatory activity seem to be effective for controlling some clin. manifestations, mainly in the chronic phase. Resveratrol (RVT) and curcumin (CUR) are natural compounds with potent antioxidant and anti-inflammatory properties and their cardioprotective effect have been proposed to have benefits to treat CD. Such effects could decrease or block the progression of the disease′s severity. The purpose of this systematic review is to analyze the effectiveness of RVT and CUR in animal and clin. research for the treatment of CD. The study was performed according to PRISMA guidelines and it was registered on PROSPERO (CDR42021293495). The results did not find any clin. study, and the animal research was analyzed according to the SYRCLES risk of bias tools and ARRIVE 2.0 guidelines. We found 9 eligible reports in this study. We also discuss the potential RVT and CUR derivatives for the treatment of CD as well. This study involved multiple reactions and reactants, such as Bisdemethoxycurcumin (cas: 33171-05-0Related Products of 33171-05-0).

The utilization of lignin to produce high value-added chems. is conducive to alleviating the fossil energy crisis. Herein, Ni nanoparticles supported on iron/nitrogen co-doped carbon was prepared by co-pyrolysis and solvothermal reduction method for catalytic hydrogenolysis (CH) of dealkaline lignin and its model compounds The catalysts were prepared under different calcination temperature, N/C ratio and Ni loading, and the optimal catalyst was Ni_10%@Fe/NC_0.33-800 (calcination temperature: 800°C, N/C ratio: 0.33, Ni loading: 10%) based the on the CH of benzyl Ph ether (BPE). Ni_10%@Fe/NC_0.33-800 showed good catalytic performance on the selective cleavage of C-O bond of lignin and its model compounds The BPE conversion reached up to 97.7% over Ni_10%@Fe/NC_0.33-800 under mild conditions (230°C, 1 MPa H₂, and 0.5 h) with toluene and cyclohexanol as major products.

A new synthetic biology approach for the production of curcumin and its glucoside in Atropa belladonna hairy roots was written by Singh, Sailendra;Pandey, Pallavi;Akhtar, Qussen Md.;Negi, Arvind Singh;Banerjee, Suchitra. And the article was included in Journal of Biotechnology in 2021.Application In Synthesis of Bisdemethoxycurcumin The following contents are mentioned in the article:

Curcumin has ignited global interest as an elite drugable mol., owing to its time-honoured pharmacol. activities against diverse human ailments. Limited natural accessibility and poor oral bioavailability caused major hurdles in the curcumin-based drug development process. We report the first successful testimony of curcumin and its glucoside synthesis in Atropa belladonna hairy roots (HR) through metabolic engineering. Re-routing the inherent biosynthetic precursors of the phenylpropanoid pathway of A. belladonna by heterologous expression of key curcumin biosynthetic pathway genes (i.e., Diketide-CoA synthase-DCS and Curcumin synthase-CURS3) and glucosyltransferase gene (CaUGT2) resulted in the production of curcumin and its glucoside in HR clones. Under shake-flask cultivation, the PGD2-HR1clone bearing DCS/ CURS3 genes showed the maximum curcumin yield (180.62 ± 4.7 μg/g DW), while the highest content of curcumin monoglucoside (32.63 ± 2.27 μg/g DW) along with curcumin (67.89 ± 2.56 μg/g DW) were noted in the PGD3-HR3 clone co-expressing DCS/CURS3 and CaUGT2 genes. Bioreactor up-scaling showed yield improvements in the PGD2-HR1 (2.3 fold curcumin) and the PGD3-HR3 clone (0.9 and 1.65 folds of curcumin-monoglucoside and curcumin resp.). These findings proved the advantageous use of HR cultures as the production source for curcumin and its glucoside, which remained unexplored so far.

Production and evaluation of novel functional extruded corn snacks fortified with ginger, bay leaves and turmeric powder was written by Amer, Sara Adel;Rizk, Ayat Ebrahim. And the article was included in Food Production, Processing and Nutrition in 2022.Product Details of 33171-05-0 The following contents are mentioned in the article:

Extruded corn snacks are accepted by all human ages especially children, but they have low functional value. Therefore, corn extruded snacks contain rich nutraceuticals dried herbs including Laurus nobilis (T1), Curcuma longa (T2), Zingiber officinale Roscoe (T3), and the mixture of these herbs (T4) were manufactured and analyzed. The results declared that all the herbal extruded corn snacks had significantly higher ash, fibers, minerals, and vitamins A and B6. For minerals, the highest percent of increase compared to control was achieved by Fe, K, Ca, Zn content in order, being the highest in T4. The contents of Vitamin A and B6 were ranged from 283 to 445 IU/100 g and from 0.01 to 0.08 mg/100 g for the herbal extrudates, resp. The increased percent in herbal corn snacks relative to control ranged from 743 to 452%, 188 to 17.6%, and from 313 to 99% for total phenolics, flavonoids, and antioxidant activity. Besides, the highest number of phenolic compounds was recorded in T4. Despite the fact that approx. all herbal extruded products had good texture and color characteristics, the best formulation was T2 and T4 corn snacks. Furthermore, the extruded products were microbiol. safe for up to 9 mo. The formulation of herbal-corn snacks could fulfill consumers′ requirement for ready-to-eat-healthy foods with acceptable sensory attributes and also economically suitable for the food industry.

Metallodrugs form a large family of therapeutic agents against cancer, among which is cisplatin, a paradigmatic member. Therapeutic resistance and undesired side effects to Pt(II) related drugs, prompts research on different metal-ligand combinations with potentially enhanced biol. activity. We present the synthesis and biol. tests of novel palladium(II) complexes containing bisdemethoxycurcumin (BDMC) 1 and 2. Complexes were fully characterized and their structures were determined by X-ray diffraction. Their biol. activity was assessed for several selected human tumor cell lines: Jurkat (human leukemic T-cell lymphoma), HCT-116 (human colorectal carcinoma), HeLa (human cervix epitheloid carcinoma), MCF-7 (human breast adenocarcinoma), MDA-MB-231 (human mammary gland adenocarcinoma), A549 (human alveolar adenocarcinoma), Caco-2 (human colorectal carcinoma), and for non-cancerous 3T3 cells (murine fibroblasts). The cytotoxicity of 1 is comparable to that of cisplatin, and superior to that of 2 in all cell lines. It is a correlation between IC₅₀ values of 1 and 2 in the eight studied cell types, promising a potential use as anti-proliferative drugs. Moreover, for Jurkat cell line, complexes 1 and 2, show an enhanced activity. DFT and docking calculations on the NF-κB protein, Human Serum Albumin (HSA), and DNA were performed for 1 and 2 to correlate with their biol. activities.

The aim of this work is to determine the fish-shaped diagram of liquid-liquid equilibrium (LLE) of ternary mixtures of water + n-alkane + n-alkyl polyglycol ether (C_iE_j) using a cloud point method with laser scattering technique. n-Octane and n-dodecane were selected as the n-alkanes, and 2-butoxyethanol (C₄E₁) and 2-(2-hexyloxyethoxy)ethanol (C₆E₂) were selected as the n-alkyl polyglycol ethers. In the measurements of the ternary mixtures, the C_iE_j free basis mass fraction “α” of n-alkane was changed from 0.1 to 0.9. The exptl. fish-shaped diagrams were evaluated by comparing the exptl. cloud point data with the fish-shaped diagrams as well as the phase boundaries of tie-line and tie-triangle data in the mixtures of water + n-octane + C₄E₁ and water + n-dodecane + C₆E₂ reported in the literature. X-points where the fish body and fish tail intersect were determined from the exptl. cloud points, as well as the upper and lower critical point temperature of the fish-body. Changes in the phase diagram and X-points with different n-alkanes, C_iE_j, and the value of α were analyzed using the exptl. data. The LLE data of the mixture of water + C₆E₂, as one of the binary components of the ternary mixture, was also measured.

Particulate and gaseous emissions from charcoal combustion in barbecue grills was written by Vicente, E. D.;Vicente, A.;Evtyugina, M.;Carvalho, R.;Tarelho, L. A. C.;Oduber, F. I.;Alves, C.. And the article was included in Fuel Processing Technology in 2018.Product Details of 2380-78-1 The following contents are mentioned in the article:

The use of charcoal for cooking and heating can be a major source of air pollution and lead to a wide range of health outcomes. The aim of this study was to exptl. quantify and characterize the gaseous and particulate matter (PM_2.5) emissions from charcoal combustion in a typical brick barbecue grill. The gaseous emission factors were 219±44.8gkg^-1 for carbon monoxide (CO), 3.01±0.698gkg^-1 for nitrogen oxides (NO_x expressed as NO₂), and 4.33±1.53gCkg^-1 for total organic carbon (TOC). Particle emissions (7.38±0.353gkg^-1 of dry charcoal burned) were of the same order of magnitude as those from traditional residential wood burning appliances. About 50% of the PM_2.5 emitted had a carbonaceous nature while water soluble ions accounted, on average, for 17% of the particulate mass. Alkanes (C₁₁-C₁₆ and C₂₃), hopanes, steranes and alkyl-PAHs accounted for small mass fractions of PM_2.5. Phenolic compounds and saccharides represented the major particle-bond organic constituents. The high proportion of either resin acids or syringyl and vanillyl compounds is consistent with emissions from charred coniferous wood. The ratios between anhydrosugars for charcoal are much lower than the values reported for lignite combustion, but overlap those from other biomass burning sources.
