Descriptive analysis of dietary (poly)phenol intake in the subcohort MAX from DCH-NG: “Diet, Cancer and Health-Next Generations cohort” was written by Lanuza, Fabian;Zamora-Ros, Raul;Rostgaard-Hansen, Agnetha Linn;Tjoenneland, Anne;Landberg, Rikard;Halkjaer, Jytte;Andres-Lacueva, Cristina. And the article was included in European Journal of Nutrition.Electric Literature of C19H16O4 The following contents are mentioned in the article:

(Poly)phenols are bioactive compounds widely distributed in plant-based foods. Currently, limited data exist on the intake distribution of (poly)phenols across meals. This study aimed to estimate dietary intakes of all individual (poly)phenols and total intake per class and subclass by meal event, and to identify their main food sources in the subcohort MAX from the Diet, Cancer and Health-Next Generations cohort (DCH-NG). Dietary data were collected using three web-based 24-h dietary recalls over 1 yr. In total, 676 participants completed at least one recall. The dietary data were linked to Phenol-Explorer database using standardized procedures and an inhouse software. We categorized foods/drinks into five options of meal events selected by the participant: ′Breakfast′, Lunch, Evening, Snack, and Drink. Adjusted total (poly)phenols mean intake by meal was the highest in the drink event (563 mg/day in men and 423 mg/day in women) and the lowest in the evening event (146 mg/day in men and 137 mg/day in women). The main overall (poly)phenol class contributor was phenolic acids (55.7-79.0%), except for evening and snack events where it was flavonoids (45.5-60%). The most consumed (poly)phenol subclasses were hydroxycinnamic acids and proanthocyanidins. Nonalcoholic beverages (coffee accounted for 66.4%), cocoa products, and cereals were the main food sources of total (poly)phenols. Conclusion: This study provides data on the variability in the intake of classes and subclasses of (poly)phenols and their main food sources by meal event according to lifestyle data, age, and gender in a Danish population. This study involved multiple reactions and reactants, such as Bisdemethoxycurcumin (cas: 33171-05-0Electric Literature of C19H16O4).

Bisdemethoxycurcumin (cas: 33171-05-0) belongs to ethers. Carboxylic acid esters of low molecular weight are colourless, volatile liquids with pleasant odours, slightly soluble in water. 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.

Autologously transplanted dermis-derived cells alleviated monobenzone-induced vitiligo in mouse was written by Erdogan, Asli;Mutlu, Hasan Serdar;Solakoglu, Seyhun. And the article was included in Experimental Dermatology in 2022.Synthetic Route of C13H12O2 The following contents are mentioned in the article:

Vitiligo is a depigmentation disease which affects skin and hair follicles with a prevalence of 0.5%-1% worldwide. In this study, we aimed to investigate treatmental potential of dermis-derived cells in monobenzone (MBEH)-induced mouse vitiligo model with light and electron microscopy. MBEH (40%) cream was topically applied to C57BL/6 mice until depigmentation occurred in vitiligo and exptl. groups. In exptl. groups, dermis-derived cells obtained from back skin biopsy samples before induction of vitiligo, were injected intradermally to vitiligo mice. On Days 3 and 15 after cell transplantation to exptl. groups, skin biopsies were compared with biopsies of control and vitiligo groups. Dermis-derived cells obtained from back skin biopsy samples of exptl. groups showed nestin and versican immunoreactivity. Melanin in hair follicles of control group was detected by histochem. stainings (Haematoxylin and eosin and Fontana-Masson) whereas sparse melanin granules were observed in hair follicles of vitiligo group. In exptl. groups, there was an increase in the number of hair follicles with melanin compared with vitiligo group. We observed MART-1 immunoreactive cells mostly around the hair follicles in control group and within dermis in vitiligo group. Electron microscopic investigation showed presence of melanosomes in hair follicles of control group and lacking in vitiligo group. In exptl. groups, both type of hair follicles were observed with electron microscope. Our data suggest that autologously transplanted dermis-derived cells may be effective in vitiligo treatment by contrubuting to melanin production This study involved multiple reactions and reactants, such as 4-Benzyloxyphenol (cas: 103-16-2Synthetic Route of C13H12O2).

4-Benzyloxyphenol (cas: 103-16-2) belongs to ethers. Esters typically have a pleasant smell; those of low molecular weight are commonly used as fragrances and are found in essential oils and pheromones. 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.Synthetic Route of C13H12O2

Imine based chiral liquid crystals: Effect of varying the terminal substituent and orientation of ester linking unit was written by Karanlik, Gurkan;Ocak, Hale;Bilgin Eran, Belkiz. And the article was included in Journal of Molecular Liquids in 2019.Related Products of 103-16-2 The following contents are mentioned in the article:

New liquid crystalline compounds composed of three-benzene-ring mol. core comprising both the imine and ester linkage units, (S)-3,7-dimethyloctyloxy chiral unit at one of terminals and n-dodecyl/dodecyloxy group as other side chain have been synthesized and characterized to study the effect of varying terminal chains, the orientation of polar ester linking group and the presence of mol. chirality on mesophase properties of imine based calamitic compounds The liquid crystalline properties of the compounds were investigated by differential scanning calorimetry, optical polarizing microscopy and electro-optic methods. As a result of the strong effect of chirality of (S)-3,7-dimethyloctyloxy chain, all Schiff bases (imines) exhibit enantiotropic chiral smectic C (SmC*), chiral nematic (N*) as well as SmX phase just below the SmC* phase and blue phase (BP) appearing monotropically. The SmC* phase shows ferroelec. switching behavior with P_S values in the range 70-130 nC cm^-2. The alteration of the n-alkyl tail with an alkoxy chain gives rise to a significant increase up to 30 °C in mesomorphic transitions. The change in the orientation of polar ester linking group has no effect on the type and sequence of observed LC phase. As compared with (S)-4-(3,7-dimethyloctyloxy)phenol based imine derivatives (7a, 7b), the chiral nematic (N*) mesophase temperature range of (S)-4-(3,7-dimethyloctyloxy)benzoate based compounds (8a, 8b) significantly broadened. Addnl., a decrease on the phase transition temperatures occurred with regardless of introducing n-dodecyl/dodecyloxy group as side chains.

4-Benzyloxyphenol (cas: 103-16-2) 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. 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.Related Products of 103-16-2

Co-pyrolytic performances, mechanisms, gases, oils, and chars of textile dyeing sludge and waste shared bike tires under varying conditions was written by Tang, Xiaojie;Chen, Xi;He, Yao;Evrendilek, Fatih;Chen, Zhiyun;Liu, Jingyong. And the article was included in Chemical Engineering Journal (Amsterdam, Netherlands) in 2022.Product Details of 112-59-4 The following contents are mentioned in the article:

The massive industrial wastes of textile dyeing sludge (TDS) and waste shared bike tires are becoming increasingly problematic environmentally and economically. Their co-pyrolysis maybe an affordable and eco-friendlier alternative so as to reduce their waste volumes and emissions, as well as recover value-added oils and chars. This study was the first to characterize the TDS co-pyrolysis with rubber (RT) vs. polyurethane (PUT) tires and their performances, mechanisms, emissions, oils, and chars as a function of temperature and blend type and ratio. The co-pyrolysis increased the total weight loss from 51.76% with TDS to 55.30% with 50% TDS and 50% RT (TR55) and to 68.92% with TP55. TR55 and TP55 yielded the best performances, with the stronger synergistic effect with the TP than TR co-pyrolysis. The optimal reaction models were second-order (F2) and five-dimension diffusion (D5) for the two devolatilization sub-stages for TDS, two thirds-order (F1.5) for the TR55 and the second and fourth sub-stages of the TP55, and F2 for the first and third sub-stages of the TP55. The co-pyrolysis reduced emissions of CO, SO₂, and nitrous compounds, did not change their temperature dependency, and produced more hydrocarbon products. The TR co-pyrolysis produced more D-limonene and isoprene and inhibited the isomerization of D-limonene. The TP co-pyrolysis further decomposed diaminodiphenylmethane into low-mol. weight benzene series such as toluene and styrene. The co-pyrolytic chars had higher branching degree of aliphatic side chain and bridge bond, with the TP ones having the enhanced char aromaticity. This study involved multiple reactions and reactants, such as 2-(2-(Hexyloxy)ethoxy)ethanol (cas: 112-59-4Product Details of 112-59-4).

Decarboxylative amination of benzoic acids bearing electron-donating substituents and nonactivated amines was written by Wang, Feilong;Han, Ying;Yu, Le;Zhu, Dianhu. And the article was included in Organic Chemistry Frontiers in 2022.Electric Literature of C12H12N2O The following contents are mentioned in the article:

A highly desirable and straightforward decarboxylative amination of readily available benzoic acids, with the long-inaccessible extension of decarboxylative amination to normally poorly reactive electron-rich benzoic acids and non-activated amines for synthesis of anilines RNR¹R² [R = 2-MeOC₆H₄, 2,6-di-MeC₆H₃, 2-methoxy-3-pyridyl, etc.; R¹ = H, Me; R² = Ph, Bn, 2-naphthyl, etc.; R¹R² = CH₂CH₂OCH₂CH₂] in moderate to high yields with excellent functional-group tolerance was reported. This aniline synthesis was applicable to a wide range of aryl/alkyl/heterocyclic amines under oxidant-free conditions, preventing adverse reactions compared to traditional methods. It also provided decarboxylative C-N modifications of complex bioactive nitrogen-bearing mols. to highlight the synthetic utility of this protocol. The theor. calculation had supported that this decarboxylative amination might proceeded via a concerted decarboxylation-iodination-type process to afford aryl iodine intermediates, which promoted a palladium-catalyzed C-N cross-coupling pathway under mild conditions. Notably, this efficient reaction featured a fine choice of the same base/solvent system to successfully achieve two independent reactions in a one-pot continuous operation process. This strategy provided a method for previously inaccessible decarboxylative amination of benzoic acids bearing electron-donating substituents, as a new alternative to the existing decarboxylative oxidative couplings. This study involved multiple reactions and reactants, such as N-(4-Methoxyphenyl)pyridin-3-amine (cas: 562085-85-2Electric Literature of C12H12N2O).

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.Electric Literature of C12H12N2O

Bisdemethoxycurcumin attenuates OVA-induced food allergy by inhibiting the MAPK and NF-κB signaling pathways was written by Wang, Yanjie;Zhang, Ping;Zhang, Jingyu;Hong, Tie. And the article was included in Experimental and Therapeutic Medicine in 2022.Synthetic Route of C19H16O4 The following contents are mentioned in the article:

Bisdemethoxycurcumin (BDMC) is an important ingredient derived from turmeric in addition to curcumin. It has been reported that BDMC can be used to treat mast cell-mediated allergic diseases. In the present study, a food allergy (FA) murine model sensitized by i.p. injection followed by oral challenge with ovalbumin (OVA) was established. BDMC was orally administered at 100 and 200 mg/kg for 11 days in the challenge phase to treat OVA-induced FA mice. FA symptoms such as diarrhea score, anaphylactic symptom score and rectal temperature were recorded. Intestinal tissue was also observed by hematoxylin and eosin staining. In addition, other allergic indicators were also analyzed by ELISA and western blot anal. The present study demonstrated that BDMC could suppress the decreases in rectal temperature, diarrhea and anaphylactic symptoms in FA mice. BDMC could also ameliorate the inflammation of intestinal tissues in FA mice. BDMC not only decreased the production of OVA-specific Ig (OVA-sIg)E, IgG1, histamine, mouse mast cell protease-1, diamine oxidase, cytokines (IL-4, IL-5 and IL-13) but increased cytokines interferon-γ production The protein expression results showed that the levels of Gata-3 were decreased but T-bet levels were increased. Furthermore, compared with the OVA group, phosphorylated (p)-p38, p-JNK, p-ERK and p-NF-κBp65 levels were decreased and p-IκBα level was increased. In conclusion, the results showed that BDMC possessed a protective effect on FA. Furthermore, BDMC was able to regulate the T-helper cells (Th)1/Th2 immune balance and inhibit the activation of MAPK and NF-κB pathways in FA mice.

Antioxidant Additives Produced from Argan Shell Lignin Depolymerization was written by Afailal, Zainab;Gil-Lalaguna, Noemi;Torrijos, Maria Teresa;Gonzalo, Alberto;Arauzo, Jesus;Sanchez, Jose Luis. And the article was included in Energy & Fuels in 2021.Formula: C9H12O3 The following contents are mentioned in the article:

The present work summarizes the results of an exptl. study focused on producing antioxidant additives for biofuels from argan shell lignin. The generation of this waste has noticeably increased in specific regions of Morocco as a result of the upward trend in the production of argan oil. Lignin extracted from argan shells via a semi-chem. pulping process was depolymerized under hydrothermal conditions in a stirred autoclave reactor at a temperature range of 250-350°C. Lignin conversion to phenolic compounds was conducted in subcritical water together with different reaction medium (H₂, CO₂, and HCOOH). The organic fraction in the aqueous liquid product was extracted and blended with biodiesel at a dosage of 1 wt % to evaluate its antioxidant potential. According to the obtained results, the biodiesel oxidation stability time was drastically improved up to 400%. The depolymerization temperature was observed as a critical factor in the antioxidant potential of the additives, showing a maximum value at 300°C, regardless of the reaction medium. An extensive characterization of the produced additives was performed. The phenolic monomers present in the produced additives were identified using gas chromatog.-mass spectrometry, finding a notable presence of catechol, especially in the additives obtained at 300°C, which led to the best results of biodiesel oxidation stability. Gel permeation chromatog. analyses of the additives also showed a well dissolution of relatively big mols. (up to 7000 Da) in biodiesel. More efforts are required to verify the actual antioxidant potential of these types of mols. This study involved multiple reactions and reactants, such as 4-Hydroxy-3-methoxyphenethanol (cas: 2380-78-1Formula: C9H12O3).

4-Hydroxy-3-methoxyphenethanol (cas: 2380-78-1) belongs to ethers. 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. 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.Formula: C9H12O3

Curcumae Radix with four botanical origins (Wenyujin, Huangyujin, Guiyujin, Lvyujin) has a long medical history in China. The four species have not been differentiated well in clin. application, though there were differences in pharmacol. effects among them. For the aim of fast discrimination and quant. anal. of Yujin, HPLC (high performance liquid chromatog.) fingerprint and UV-Vis (UV-visible) spectroscopy technologies coupled with chemometrics were employed. The HPLC fingerprints of 26 Guiyujin, 11 Huangyujin, 11 Lvyujin, 29 Wenyujin and full 77 samples were sep. established, with good similarities among same species except Wenyujin and poor consistence in full samples. UV-Vis spectra showed obvious three absorption peaks in the spectra of Huangyujin samples and only one in that of the rest samples. LDA (linear discriminant anal.) and Bagged Trees models established based on HPLC fingerprint data attained higher than 90% discrimination accuracy. Based on the spectral data, complete separation for the four species of Yujin was failed to achieve by PCA (principal component anal.), and the KNN (k-nearest neighbors) and SVM (support vector machine) models achieved no<90% discrimination accuracies. Furthermore, the SVMR (support vector machine regression) and Bagged Trees Regression models used to quickly predict the contents of germacrone, curcumenol and curdione performed well, with relatively lower RMSE (root mean square error) and higher R² (coefficient of determination) values. The present study proposed relatively rapid methods for the determination of bioactive compounds and discrimination of Yujin.

Solid-inclusion compounds of ethylene glycol Bu ether (C₄E₁), di(ethylene glycol) Bu ether (C₄E₂) and di(ethylene glycol) hexyl ether (C₆E₂) in β-cyclodextrin (βCD), with general formula represented by the notation {βCD·C_nE_m}, were prepared from aqueous solution and characterized by powder X-ray diffraction (PXRD), thermogravimetric anal. (TGA), FT-Raman and ¹³C CP MAS NMR spectroscopies, at ambient humidity, as true hydrated microcrystalline inclusion compounds, pointing to a cage structure for {βCD·C₄E₁} and a channel structure for both {βCD·C₄E₂} and {βCD·C₆E₂}. In addition, the inclusion compounds were investigated at several defined relative humidities (RHs). Several relative intensities of βCD Raman bands generally ascribed to C-O stretching and CH₂ bending vibrations are found to be influenced by the presence of guests in the βCD cavity or the increase of ambient humidity, or by both of these factors. PXRD patterns show that crystalline structures are preserved for RHs equal or above 20%. Interestingly, important changes on the multiplicity of resonances and in the dispersions of ¹³C CP MAS NMR chem. shifts values for all the carbon atoms of the βCD macrocycle are observed in passing from RH 15% to 20%, suggesting amorphous structures below RH 20%. Overall, the above findings converge to stress the structural relevance of hydration water in the βCD inclusion compounds, either with a cage packing arrangement or with a channel structure.
