Sulfenate Esters of Simple Phenols Exhibit Enhanced Activity against Biofilms was written by Walsh, Danica J.;Livinghouse, Tom;Durling, Greg M.;Chase-Bayless, Yenny;Arnold, Adrienne D.;Stewart, Philip S.. And the article was included in ACS Omega in 2020.Formula: C13H12O2 The following contents are mentioned in the article:

The recalcitrance exhibited by microbial biofilms to conventional disinfectants has motivated the development of new chem. strategies to control and eradicate biofilms. The activities of several small phenolic compounds and their trichloromethylsulfenyl ester derivatives were evaluated against planktonic cells and mature biofilms of Staphylococcus epidermidis and Pseudomonas aeruginosa. Some of the phenolic parent compounds are well-studied constituents of plant essential oils, for example, eugenol, menthol, carvacrol, and thymol. The potency of sulfenate ester derivatives was markedly and consistently increased toward both planktonic cells and biofilms. The mean fold difference between the parent and derivative min. inhibitory concentration against planktonic cells was 44 for S. epidermidis and 16 for P. aeruginosa. The mean fold difference between the parent and derivative biofilm eradication concentration for 22 tested compounds against both S. epidermidis and P. aeruginosa was 3. This work demonstrates the possibilities of a new class of biofilm-targeting disinfectants deploying a sulfenate ester functional group to increase the antimicrobial potency toward microorganisms in biofilms. This study involved multiple reactions and reactants, such as 4-Benzyloxyphenol (cas: 103-16-2Formula: C13H12O2).

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, including apples, durians, pears, bananas, pineapples, and strawberries. 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.Formula: C13H12O2

Geographical Discrimination of Curcuma longa L. in Vietnam Based on LC-HRMS Metabolomics was written by Nguyen Thi, Kieu-Oanh;Do, Hoang-Giang;Duong, Ngoc-Tu;Nguyen, Tien Dat;Nguyen, Quang-Trung. And the article was included in Natural Product Communications in 2021.Reference of 33171-05-0 The following contents are mentioned in the article:

Curcuma longa L. has been used as a food, cosmetic, traditional medicine, and natural dye for a long time in tropical and subtropical regions such as India, China, and Vietnam. Curcuminoids are considered the main bioactive compounds in this plant. This study focuses on metabolites profiling of the rhizome methanolic extract of C longa samples collected in 6 different provinces in Vietnam using liquid chromatog. coupled with high-resolution mass spectrometry. The partial least-squares discriminant anal. model was then established to discriminate its metabolomes and identify the chemomarkers that help to distinguish C longa from 6 geog. locations. Consequently, collected samples were segregated into 3 main groups: northern (Lang Son, with typical content of 2 terpenoids), center (Nghe An), and southern highland (Lam Dong, with distinctive profile of 3 curcuminoids). The absolute curcuminoids’ amount was also measured based on the calibration curve of reference standards The differential metabolites including curcumin, demethoxycurcumin, and bisdemethoxycurcumin were found with the highest range in samples from Lang Son, indicating the excellent quality of turmeric cultivated in this area. This study involved multiple reactions and reactants, such as Bisdemethoxycurcumin (cas: 33171-05-0Reference of 33171-05-0).

Annulation-Triggered Denitrogenative Transformations of 2-(5-Iodo-1,2,3-triazolyl)benzoic Acids was written by Voloshkin, Vladislav A.;Kotovshchikov, Yury N.;Latyshev, Gennadij V.;Lukashev, Nikolay V.;Beletskaya, Irina P.. And the article was included in Journal of Organic Chemistry in 2022.Application of 109-85-3 The following contents are mentioned in the article:

The ability of [1,2,3]triazolobenzoxazinones I (R¹ = H, 7-Br, 9-Me; R² = n-Bu, Ph, cyclohexylmethyl, 3-methylbutyl) to act as a source of “hidden” diazo group was discovered. These diazo precursors can be easily prepared by the intramol. cyclization of 2-(5-iodo-1,2,3-triazolyl)benzoic acids II (R³ = H, 5-Br, 3-Me, etc.). The Cu-catalyzed capture of the hidden diazo group allows for further functionalization through the denitrogenative pathway. The transformations proceed via the formation of either diazoimine or diazoamide intermediates. Novel routes to various anthranilamides R³NHC(O)CH(R²)R⁴ (R³ = 4,5-dimethoxy-2-[(pyrrolidin-1-yl)carbonyl]benzen-1-yl, 2-[(morpholin-4-yl)carbonyl]benzen-1-yl, 4-bromo-2-[(pyrrolidin-1-yl)carbonyl]benzen-1-yl, etc.; R⁴ = pyrrolidin-1-yl, (5-methyl-1,3,4-thiadiazol-2-yl)sulfanyl, morpholin-4-yl, etc.) as well as thiolated benzoxazinones III (R⁵ = 5-methyl-1,3,4-thiadiazol-2-yl, 1,3-benzoxazol-2-yl, 1-methyl-1H-1,2,3,4-tetrazol-5-yl, etc.) were developed using the one-pot cyclization/diazo capture procedure. This study involved multiple reactions and reactants, such as 2-Methoxyethylamine (cas: 109-85-3Application of 109-85-3).

2-Methoxyethylamine (cas: 109-85-3) 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. 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.Application of 109-85-3

Ascorbic acid prevents yellowing of fresh-cut yam by regulating pigment biosynthesis and energy metabolism was written by Zhao, Xiaoyan;Guo, Shuang;Ma, Yue;Zhao, Wenting;Wang, Pan;Zhao, Shuang;Wang, Dan. And the article was included in Food Research International in 2022.Category: ethers-buliding-blocks The following contents are mentioned in the article:

The fresh-cut yam would turn yellow under 25°C for 36 h, which could reduce consumer’s acceptance. This study aimed to investigate the mechanism by which 2% ascorbic acid inhibits yellowing of fresh-cut yam by detecting enzyme activities, gene expressions and metabolites. Ascorbic acid treatment was found to decrease ATPase activities, ATP content, and energy charge. The transcriptional expression levels of citrate synthase, acetyl-CoA carboxylase, and acetyl-CoA synthetase, which are involved in the tricarboxylic acid cycle, were also decreased by ascorbic acid treatment, thus blocking the supply of precursors and energy for pigment biosynthesis. In addition, ascorbic acid effectively inhibited the formation of carotenoids, flavonoids, and bisdemethoxycurcumin, as indicated by lower metabolic levels, decreased enzyme activities, and downregulated transcriptional expressions. Thus, ascorbic acid prevents yellowing in fresh-cut yam by reducing the energy metabolism level as well as inhibiting pigment (carotenoids, flavonoids, bisdemethoxycurcumin) biosynthesis pathways. Accordingly, ascorbic acid treatment is a safe, effective, and cheap method for inhibiting fresh-cut yam yellowing. This study involved multiple reactions and reactants, such as Bisdemethoxycurcumin (cas: 33171-05-0Category: ethers-buliding-blocks).

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.

Effect of Reaction Conditions on Catalytic and Noncatalytic Lignin Solvolysis in Water Media Investigated for a 5 L Reactor was written by Ghoreishi, Solmaz;Barth, Tanja;Hermundsgaard, Dag H.. And the article was included in ACS Omega in 2019.Formula: C9H12O3 The following contents are mentioned in the article:

The high content of oxygen in the lignin polymer and the prevalence of phenolic functional groups make the conversion of lignin to fuels and value-added products with well-defined chem. properties challenging. The lignin-to-liquid process using a water/formic acid reaction medium has been shown to convert the lignin polymer to monomers with a mol. weight range of 300-600 Da. The bio-oil comprises a complex mixture of monomeric phenols, aromatics, and aliphatic hydrocarbons with a high H/C and low O/C ratio. This study investigates the effect of the stirring rate, level of loading, and catalyst at 305 and 350 °C in a 5 L pilot scale reactor. The oil yields are found to be highest for experiments conducted using the maximum stirring rate, maximum level of loading, and Ru/Al₂O₃ catalyst with yields of more than 69 weight % on lignin intake. Goethite as a catalyst does not show good conversion efficiency at either reaction temperatures The carbon recovery is highest for products produced at 305 °C. Furthermore, results from solid phase extraction on a DSC-CN solid phase show that 65-92 weight % the bio-oils can be recovered as fractions separated based on polarity. 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.

Germination and drying induced changes in the composition and content of phenolic compounds in naked barley was written by Ge, Xiangzhen;Saleh, Ahmed S. M.;Jing, Luzhen;Zhao, Kun;Su, Chunyan;Zhang, Bo;Zhang, Qian;Li, Wenhao. And the article was included in Journal of Food Composition and Analysis in 2021.Reference of 33171-05-0 The following contents are mentioned in the article:

Naked barley grains were germinated at 25°C for 12, 24, and 36 h, followed by IR or hot air drying. Effects of germination and drying treatments on the composition and content of phenolic compounds in naked barley were investigated using matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS). The results revealed that germination of naked barley induced significant changes in the profile of phenolic compounds depending on germination period. Also, the content of phenolic compounds significantly increased (P < 0.05) as the germination prolonged to up to 36 h. Furthermore, significantly greater retention of phenolic compounds was found after the IR drying of germinated naked barley than that found after hot air drying. Phenolic compounds of the raw and germinated/dried naked barley samples could be differentiated independently by partial least squares discrimination anal. (PLS-DA). The obtained results suggest that germination and IR drying are promising processing methods for producing germinated naked barley rich in flavonoids with potential health benefits.

Toward an Increased Functionality in Oyster (Pleurotus) Mushrooms Produced on Grape Marc or Olive Mill Wastes Serving as Sources of Bioactive Compounds was written by Koutrotsios, Georgios;Kalogeropoulos, Nick;Kaliora, Andriana C.;Zervakis, Georgios I.. And the article was included in Journal of Agricultural and Food Chemistry in 2018.COA of Formula: C9H12O3 The following contents are mentioned in the article:

Pleurotus ostreatus, P. eryngii, and P. nebrodensis were cultivated on nonconventional substrates containing grape marc (GMC) or olive mill byproducts (OMB); wheat straw (WHS) served as control. GMC-based media demonstrated equal/better mushroom productivity than WHS for P. eryngii and P. nebrodensis, while the cultivation performance of P. eryngii was improved in OMB-based media. Both GMC and OMB substrates led to large increase of fruit-bodies content in phenolic acids, resveratrol, triterpenic compounds, and ergosterol; in particular, P. eryngii mushrooms presented significantly more total phenolics and exhibited much higher antioxidant activity (2- to 8-fold increase). Furthermore, substrates containing GMC or OMB presented up to 27% increase in mushroom β-glucans. Overall, Pleurotus species responded in a different and mostly substrate-specific manner by selectively absorbing organic compounds Phenolics and squalene content of substrates correlated very well with mushrooms antioxidant activity and ergosterol, resp.; the same was observed for triterpenics’ content of substrates and mushrooms.

Gentamicin has been widely prescribed since the last two decades despite its ototoxicity and nephrotoxicity. Bisdemethoxycurcumin (BDMC) is an affordable and safe curcuminoid with medicinal properties. We aimed to understand the effects of BDMC on the gentamicin-induced hair cell damage in mouse cochlear UB/OC-2 cells, in order to elucidate the therapeutic potential of BDMC against gentamicin-induced ototoxicity. We quantified the cell membrane potential and examined the regulators and cascade proteins in the intrinsic pathway of hair cell apoptosis. Mouse cochlear UB/OC-2 cells were treated with BDMC before exposure to gentamicin. The effects of BDMC on hair cell viability, mitochondrial function, and apoptosis-related proteins were examined by flow cytometry, western blot, and fluorescent staining. Our results revealed that BDMC reversed gentamicin-mediated cycle arrest at the G2/M phase, stabilizing the mitochondrial membrane potential, decreasing cleaved caspase proteins, and successfully reversing hair cell apoptosis. BDMC is a potential agent for reducing gentamicin-induced ototoxicity.

Study of the neurochemical alterations produced by acute and subchronic Pb-exposure in Meriones shawi: Immunohistochemical study of Reissners fiber secretion by the subcommissural organ after curcumin-III treatment was written by Tamegart, Lahcen;Abbaoui, Abdellatif;Laabbar, Wafaa;Oukhrib, Mjid;Bouyatas, My Mustapha;Gamrani, Halima. And the article was included in Journal of Trace Elements in Medicine and Biology in 2022.Recommanded Product: Bisdemethoxycurcumin The following contents are mentioned in the article:

Lead neurotoxicity is associated with numerous alterations including behavioral and neurochem. disruptions. This study evaluates the possible neurochem. disruption in the subcommissural organ (SCO) after acute (three days) and subchronic (six weeks) Pb-exposure inMeriones shawi, and the possible effect of the third active compound, curcumin-III, in mitigating the neurol. alterations caused by lead exposure. Using immunohistochem. stainings, we evaluated the Reissners fiber (RF) secretion utilizing RF-antibody in the SCO. We compared both acute (25 mg/kg bw of Pb i.p. for 3 days) and subchronic (3 g/l of Pb in drinking water for six weeks) Pb-treatedMeriones shawi. The two models of lead exposure showed a significant increase in RF level in the SCO. Conversely, co-treatment with Curcumin-III at a dose of 30 mg/kg bw significantly ameliorate SCO secretory activity, as revealed by decreased RF-immunoreactivity. Together, our findings suggest the protective effects of Curcumin-III in regulating the secretory activity of the SCO after Pb-induced neuroanatomical disruptions of the SCO in Meriones.
