4-Hydroxy-3-methoxyphenethanol (cas: 2380-78-1) belongs to ethers. Esters are also usually derived from carboxylic acids. It may also be obtained by reaction of acid anhydride or acid halides with alcohols or by the reaction of salts of carboxylic acids with alkyl halides. 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.Product Details of 2380-78-1

Fractionation of Lignin with Decreased Heterogeneity: Based on a Detailed Characteristics Study of Sequentially Extracted Softwood Kraft Lignin was written by Liu, Rui;Smeds, Annika;Wang, Luyao;Pranovich, Andrey;Hemming, Jarl;Willfor, Stefan;Zhang, Hongbo;Xu, Chunlin.

Industrial lignin fractionation is attracting increasing interest due to its enormous potential in the development of high value-added materials. However, the widely reported fractionation approaches are primarily focused on the separation of fractions with a low polydispersity index (PDI). In this study, based on the detailed characteristic examination of carefully sequential-extracted softwood Kraft lignin fractions, a novel method to isolate lignin fraction with decreased heterogeneity (LGF-dh), was established in consideration of impurities, elemental composition, molar mass distribution, carbohydrate content, functional hydroxyl content, and the content of lignin-relevant aromatic units. To characterize the mentioned properties, an elemental analyzer, SEC-MALS, GC-MS, GC-FID, Py/GC-MS, 31P-NMR, and HSQC-NMR were used to compare the differences of the sequential lignin fractions that were obtained by Me tert-Bu ether (MTBE), Et acetate (EtOAc), ethanol (EtOH), methanol (MeOH), acetone, and dioxane. Moreover, a practical and feasible three-step extraction process was proposed to sep. the low heterogeneity lignin fraction from industrial lignin according to the different solubilities of each fraction in the green cosolvent system of EtOH/water, MeOH/water, and acetone/water. Overall, this work presented a comprehensive study on the properties of softwood lignin as well as proposed a feasible and convenient method to reduce the heterogeneity of lignin, which would promote its valorization.

4-Hydroxy-3-methoxyphenethanol (cas: 2380-78-1) 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, including apples, durians, pears, bananas, pineapples, and strawberries. 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.

Overweight and obesity are major risk factors for degenerative diseases, including cardiometabolic disorders and cancer. Research on fat and fatty acids′ type is attracting less attention than that on carbohydrates. High adherence to a Mediterranean diet is associated with a better prognosis. One characteristic of the Mediterranean diet is extra-virgin olive oil (EVOO) as the foremost source of dietary fat. EVOO is different than other vegetable oils because it contains peculiar “minor” components, mainly phenolic in nature. Even though olive oil is highly caloric, unrestricted use of olive oil in the PREDIMED trial did not result in weight gain. We sought to study the effects of EVOO in an appropriate mouse model of increased body weight Furthermore, we explored the biochem. and metabolomic responses to EVOO consumption. C57BL/6N male mice were weight-matched and fed ad libitum with the following diets, for 16 wk: 1) saturated fatty acid diet (SFA) or 2) extra-virgin olive oil diet (EVOO), a custom-prepared diet, isocaloric compared to SFA, in which 82% of fat was replaced by high (poly)phenol EVOO. We evaluated glucose homeostasis, serum biochem. and plasma metabolomics, in addition to cardiac and hepatic gene profile, and mitochondrial respiration rate. Replacing saturated fatty acids (e.g. lard) with EVOO translates into moderate yet beneficial cardiometabolic and hepatic effects. Future research will further clarify the mechanisms of action of EVOO (poly)phenols and their role in a balanced diet.

The beta-1 adrenergic receptor (ADRB1) is a promising therapeutic target intrinsically involved in the cognitive deficits and pathol. features associated with Alzheimer’s disease (AD). Evidence indicates that ADRB1 plays an important role in regulating neuroinflammatory processes, and activation of ADRB1 may produce neuroprotective effects in neuroinflammatory diseases. Novel small mol. modulators of ADRB1, engineered to be highly brain permeable and functionally selective for the G protein with partial agonistic activity, could have tremendous value both as pharmacol. tools and potential lead mols. for further preclin. development. The present study describes our ongoing efforts toward the discovery of functionally selective partial agonists of ADRB1 that have potential therapeutic value for AD and neuroinflammatory disorders, which has led to the identification of the mol. STD-101-D1. As a functionally selective agonist of ADRB1, STD-101-D1 produces partial agonistic activity on G protein signaling with an EC50 value in the low nanomolar range, but engages very little beta-arrestin recruitment compared to the unbiased agonist isoproterenol. STD-101-D1 also inhibits the tumor necrosis factor α (TNFα) response induced by lipopolysaccharide (LPS) both in vitro and in vivo, and shows high brain penetration. Other than the therapeutic role, this newly identified, functionally selective, partial agonist of ADRB1 is an invaluable research tool to study mechanisms of G protein-coupled receptor signal transduction.

Pterocarpus is one of the most widely used timber resources on the market. But the utilization rate has been low. In order to improve the utilization of Pterocarpus processing residue, as well as explore the reason of its good decay-resistance. In this study, the antifungal mechanism of Peterocarpes spp., aqueous extracts and ethanol extracts of three Pterocarpus species were studied. The antimicrobial active factors were analyzed by gas chromatog.-mass spectrometry. Italian poplar (Populus euramevicana cv. I-214) wood was immersed in the extracts and then inoculated with both Coriolus versicolor and Gloeophyllum trabeum. The antimicrobial properties of the extracts were studied, and the mechanism underlying these properties were analyzed using gas chromatog.-mass spectrometry. The results showed that the yield of ethanol extracts from the three Pterocarpus species was significantly higher than that of aqueous extracts Pterocarpus soyauxii and Pterocarpus macarocarpus produced the highest yield of ethanol extracts (28.59%) and aqueous extracts (14.31%), resp. With increasing concentrations, the antimicrobial activities of aqueous extracts of Pterocarpus angolensis and Pterocarpus macarocarpus gradually increased, while the antimicrobial activity of other extracts remained constant Gas chromatog.-mass spectrometry anal. identified a considerable number of phenols, ketones, amines, and aromatic compounds in all extracts, which is consistent with their antimicrobial activity and suggests synergism among the chems.

Nishamalaki is an Ayurvedic herbal formulation used to treat type 2 diabetes mellitus (T2DM), comprises Emblica officinalis and Curcuma longa. One of the main cause of T2DM is Insulin Resistance (IR) hence, this study was planned to evaluate IR lowering effect of a standardized Nishamalaki extract “EmbliQur” in high-fat diet (HFD) and streptozotocin (STZ) induced T2DM rats. Curcuminoids (23.89% weight/weight), gallic acid (5.27% weight/weight) and tannins (25.44% weight/weight) were quantified from EmbliQur. Rats were fed HFD throughout the study of 45 days and received STZ (40 mg/kg, i.p) on the 15th day of the study. Rats with more than 250 mg/dL of fasting blood glucose level (FBGL) were considered diabetic and selected for administration of EmbliQur (500 mg and 1000 mg/kg) or the standard drug metformin (120 mg/kg, p.o) from the 18th day of the study for the next 27 days. FBGL and insulin levels of all rats were measured weekly and an oral glucose tolerance test (OGTT) was done at the end of the study. The values of FBGL and insulin were used to calculate IR by the HOMA-IR, QUICKI and Matsuda methods. Rats treated with STZ/HFD had significantly higher than normal FBGL and insulin levels throughout the study and exhibited skewed IR indexes in the above three methods of IR assessment. EmbliQur treatment successfully lowered the HFD/STZ-elevated BGL and insulin levels, and ameliorated IR in all models of IR evaluation. EmbliQur 1000 mg/kg was noted to be more effective than EmbliQur 500 mg/kg in alleviating IR.

Acacia mearnsii De Wild. has been cultivated in Brazil mainly for the extraction of tannins from bark, but its wood has been used to complement the demand for hardwood in the pulp and paper industries. However, few studies have been carried out aiming to characterize the chem. composition of the wood lipophilic extracts from this species. Some compounds of these extract may generate sticky deposits in machinery in the paper and pulp mills, known as pitch. In general, woods with a higher content of lipophilic extracts generate more problems and damage caused by pitch deposits. So, this paper details the chem. composition of the lipophilic extracts of A. mearnsii woods of four ages (4, 7, 10 and 13-yr-old) cultivated in Brazil. The wood from 7, 10 and 13-years-old trees showed similar amounts of lipophilic extracts ranging from 0.23 to 0.28%. However, the 4-yr-old wood presented more than twice that value i.e. 0.60%. These lipophilic extracts were analyzed by GC-MS before and after alk. hydrolysis, followed by derivatization. The main chem. classes found were fatty acids (27.1-95.0 mg kg-1), sterols (20.5-55.7 mg kg-1) and aromatic compounds (0.750-13.2 mg kg-1), followed by smaller amounts of long chain aliphatic alc. (0.00-3.46 mg kg-1) and hydrocarbons (0.00-2.62 mg kg-1), before and after hydrolysis. The results showed that the wood extracts from 7, 10 and 13-yr-old trees were similar from the quant. and qual. points of view, indicating that harvests over 7 years of age offer less propensity for pitch problems.

Essential oils (EOs) and their chem. components are often proposed as an alternative to synthetic pesticides for pest control of foodstuff insect pests. However, their low persistence and strong, spicy odor, make them poorly suitable for use to protect food. Modification of the EOs components mols. increases their mol. weight and reduce their volatility. However, the effectiveness of such modified mols. has, so far, not been tested against stored food insect pests. In this study, the intensity and the duration of the repellence against the insect pest Sitophilus oryzae of a recently synthesized quasi-dimeric eugenol derivative (ED) (C18H20O4) were compared to those of eugenol and three eugenol related compounds The hypothesis tested was that by its higher mol. weight and two functional groups the ED would overcome the low persistence and strong and spicy odor drawback of eugenol without compromising the repellence against insects. The insect behavioral tests showed a greater repellence and persistence of ED than eugenol and the three eugenol related compounds against S. oryzae. The sensory anal. of ED by panel test indicated that ED is significantly less odorous than eugenol without any spicy nor balsamic nuances in its smell profile. Because of its high repellence against insects and its low smell intensity for humans, ED could represent a valid repellent for the control of foodstuffs insect pests. 2022 The Authors.

In this study, we have developed and validated a liquid chromatog.-tandem mass spectrometry (LC-MS/MS) method using a tandem sector quadrupole mass spectrometer to simultaneously detect and quantify three curcuminoids (curcumin, demethoxycurcumin, and bisdemethoxycurcumin) and three of the most common food adulterants, particularly in turmeric, namely, metanil yellow, Sudan I, and Sudan red G using a single 11 min method. The method was validated for linearity, precision, and accuracy. The limit of quantification (LOQ) and the limit of detection (LOD) were determined as 1-2 and 0.1-0.2 ng/mL, resp., for all six analytes. The method is accurate and precise, with intraday and interday accuracies ranging from 86.4 to 108.1 and from 86.0 to 107.7%, resp., and intraday and interday coefficients of variation (CVs) ranging from 0.9 to 5.2 and 1.6 to 5.6%, resp. A simple extraction procedure, easy sample preparation, high sensitivity, and rapid anal. make this method suitable for routine analyses. The validated method was applied to quantify curcuminoids in six com. turmeric supplements. The amounts of curcuminoids varied significantly (~30-fold) among the six supplements investigated in the present study. To demonstrate the practical applicability of the validated method, a com. dietary turmeric supplement was spiked with 0.002-1% of adulterants, and their concentrations were accurately quantified.

Biomass pyrolysis oil is a potentially essential renewable energy source that can serve as an alternative to petroleum-based fuels and chems. In this study, biomass pyrolysis oil was converted into petroleum-like deoxygenated hydrocarbons via catalytic hydrodeoxygenation using a titania-supported nickel phosphide catalyst. The phosphor precursor was added to several transition metals, including nickel, cobalt, copper, and iron, supported on titania. The formation of isolated nickel phosphide particles, which were active for complete hydrodeoxygenation, was confirmed by the characterization of prepared catalysts. As a model reactant of biomass pyrolysis oil, a mixture of alkyl-methoxyphenol compounds was hydrodeoxygenated to produce completely deoxygenated compounds, generating an 87% yield of cycloalkanes at 300 °C and 4 MPa H2 for a reaction time of 2 h. The hydrodeoxygenation of biomass pyrolysis oil also generated a 37.4% yield of hydrocarbon fuels. The high hydrodeoxygenation activity can be attributed to the synergy between the hydrogenating metals and the acid sites, which can be improved by electron transfer from a slightly cationic nickel to a slightly anionic phosphor. Furthermore, the addition of phosphor improved the formation of highly dispersed nickel particles, increasing the quantity of hydrogen-adsorbing surface metals. The observations in this study indicate that the efficient conversion of lignocellulose-derivatives into chems. and fuels can be achieved using modified non-precious transition metal catalysts.

Infinite-dilution relative volatility (αi.water) was measured at 50° and 80° using a Rayleigh distillation apparatus for dilute solutions of propylene glycol Bu ether (PnB), propylene glycol Pr ether (PnP), and dipropylene glycol Bu ether (DPnB) dissolved in water and brine (3% NaCl). The data were analyzed to determine infinite-dilution activity coefficient (γi,aqueous), Henry’s Law constant, partial molar enthalpy of mixing, and Setschenow constant Partition ratio (K) for extraction of PnP was also measured using 14 hydrophobic organic extraction solvents, including alcs., ketones, ethers, chlorinated hydrocarbons, aromatics, and aliphatics. An interpretation of mol. interactions in solution is given based on the anal. of activity coefficients, as a function of temperature and salt concentration General rules are proposed for the class of hydrogen-bonding organic compounds characterized by the presence of a lower critical solution temperature (LCST) in the organic + water phase diagram. The αi,water is likely to increase as the temperature increases for stripping volatile LCST-type hydrogen-bonding organics from dilute aqueous solution, provided the pure-component vapor pressure relative to water (pSATi/pSATwater) also increases or stays approx. the same. For extraction of LCST-type compounds from aqueous solution, K is likely to increase as the temperature increases, provided that the mutual solubility between phases is low. This study involved multiple reactions and reactants, such as 2-(2-(Hexyloxy)ethoxy)ethanol (cas: 112-59-4Product Details of 112-59-4).

2-(2-(Hexyloxy)ethoxy)ethanol (cas: 112-59-4) belongs to ethers. Carboxylic acid esters of low molecular weight are colourless, volatile liquids with pleasant odours, slightly soluble in water. 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.Product Details of 112-59-4
