Active ingredients and mechanisms of Phellinus linteus (grown on Rosa multiflora) for alleviation of Type 2 diabetes mellitus through network pharmacology was written by Oh, Ki Kwang;Adnan, Md.;Cho, Dong Ha. And the article was included in Gene in 2021.Reference of 2253-73-8 The following contents are mentioned in the article:

Phellinus linteus (mushroom) grown on Rosa multiflora (PL@RM), exposed beneficial effect and safety on Type 2 diabetes mellitus (T2DM) from Korean folk remedies. However, its active chem. constituents and mechanism(s) against T2DM have not been confirmed. Hence, we deciphered the active compounds and mechanism(s) of PL@RM against T2DM through network pharmacol. GC-MS of PL@RM manifested 54 compounds and drug-likeness properties of these compounds were confirmed by Lipinski’s rule. The compound (40) related genes were composed of Similarity Ensemble Approach (SEA) and SwissTargetPrediction (STP). The overlapping genes (61) between the two databases were identified. Besides, the T2DM related genes (4,736) were extracted from DisGeNet and OMIM database. In parallel, a Venn diagram was constructed between the overlapping genes (61) and T2DM related genes (4,736), and finally, 48 genes were picked. The interactive networks between compounds and overlapping genes were plotted and visualized by RStudio. In addition, KEGG Pathway enrichment anal. was evaluated by String. String anal. showed that the mechanisms of PL@RM against T2DM were related to 16 pathways, where inhibition of gluconeogenesis by inactivating metabolic pathways was noted as the hub pathway of PL@RM against T2DM. Besides, bubble chart indicated that activation of the AMPK signaling pathway might enhance the insulin receptor (IR) phosphorylation, which is regarded the key signaling pathway of PL@RM against T2DM. Furthermore, the autodock vina revealed the promising binding affinity energy of the epicholesterol (the most drug-likeness compound) on HMGCR (hub gene). Overall, this work hints at the therapeutic evidence of PL@RM on T2DM, and this data expound the main chem. compounds and mechanisms of PL@RM against T2DM. This study involved multiple reactions and reactants, such as Isopropylisothiocyanate (cas: 2253-73-8Reference of 2253-73-8).

Isopropylisothiocyanate (cas: 2253-73-8) belongs to esters. Carboxylic acid esters of low molecular weight are colourless, volatile liquids with pleasant odours, slightly soluble in water. 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.Reference of 2253-73-8

A non-phosgene process for bioderived polycarbonate with high molecular weight and advanced property profile synthesized using amino acid ionic liquids as catalysts was written by Zhang, Zhencai;Xu, Fei;Zhang, Yaqin;Li, Chenhao;He, Hongyan;Yang, Zifeng;Li, Zengxi. And the article was included in Green Chemistry in 2020.Application In Synthesis of Diphenyl carbonate The following contents are mentioned in the article:

The conversion of biomass and carbon dioxide to plastics is one of the key solutions to reduce the greenhouse effect and alleviate the petroleum resource depletion. However, there is still a lack of bioderived polymers with high mol. weights and excellent performance and their corresponding green synthesis processes, which limits the potential of bioderived polymers to replace petroleum-based polymers. In this study, an eco-friendly synthetic process for bioderived polycarbonate, catalyzed by amino acid ionic liquids, was developed by utilizing isosorbide (ISO) and di-Ph carbonate (DPC) as reactants, derived from a renewable resource and carbon dioxide, resp. By using 1-ethyl-3-methylimidazole lysine ([Emim][Lys]) as a catalyst, poly(isosorbide carbonate) (PIC) with the weight average mol. weight of 150 000, the highest reported so far to the best of our knowledge, was synthesized, and the T_g of PIC was up to 174掳C. The reaction mechanism was investigated using NMR spectroscopy, matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-ToF MS), and d. functional theory (DFT) calculation The remarkable catalytic performance was attributed to the fact that [Emim][Lys] could effectively activate the hydroxyl group of ISO and carbonyl group of DPC, and inhibit the formation of cyclic intermediates. Moreover, to overcome the brittleness of PIC, 1,4-butanediol (BD) and 1,4-cyclohexanedimethanol (CHDM) were introduced into PIC, and the copolycarbonate showed excellent Young’s modulus, ultimate tensile strength, and elongation at break, which were 979 MPa, 57 MPa, and 145%, resp., and were comparable to the com. petroleum-based polycarbonates. Such a process provides further industrial prospects for the next generation of bioderived polycarbonate. This study involved multiple reactions and reactants, such as Diphenyl carbonate (cas: 102-09-0Application In Synthesis of Diphenyl carbonate).

Diphenyl carbonate (cas: 102-09-0) belongs to esters.

Biodegradation of volatile organic compounds by five fungal species was written by Qi, B.;Moe, W. M.;Kinney, K. A.. And the article was included in Applied Microbiology and Biotechnology in 2002.SDS of cas: 763-69-9 The following contents are mentioned in the article:

Five fungal species, Cladosporium resinae (ATCC 34066), Cladosporium sphaerospermum (ATCC 200384), Exophiala lecanii-corni (CBS 102400), Mucor rouxii (ATCC 44260), and Phanerochaete chrysosporium (ATCC 24725), were tested for their ability to degrade nine compounds commonly found in industrial off-gas emissions. Fungal cultures inoculated on ceramic support media were provided with volatile organic compounds (VOCs) via the vapor phase as their sole carbon and energy sources. Compounds tested included aromatic hydrocarbons (benzene, ethylbenzene, toluene, and styrene), ketones (Me Et ketone, Me iso-Bu ketone, and Me Pr ketone), and organic acids (Bu acetate, Et 3-ethoxypropionate). Experiments were conducted using three pH values ranging from 3.5 to 6.5. Fungal ability to degrade each volatile organic compound (VOC) was determined by observing the presence or absence of visible growth on the ceramic support medium during a 30-day test period. The results indicate that E. lecanii-corni and C. sphaerospermum can readily utilize each of the nine VOCs as a sole carbon and energy source. P. chrysosporium was able to degrade all VOCs tested except for styrene under the conditions imposed. C. resinae was able to degrade both organic acids, all of the ketones, and some of the aromatic compounds (ethylbenzene and toluene); however, it was not able to grow utilizing benzene or styrene under the conditions tested. With the VOCs tested, M. rouxii produced visible growth only when supplied with Bu acetate or Et 3-ethoxypropionate. Maximum growth for most fungi was observed at a pH of approx. 5.0. The exptl. protocol utilized in these studies is a useful tool for assessing the ability of different fungal species to degrade gas-phase VOCs under conditions expected in a biofilter application. This study involved multiple reactions and reactants, such as Ethyl 3-ethoxypropanoate (cas: 763-69-9SDS of cas: 763-69-9).

Ethyl 3-ethoxypropanoate (cas: 763-69-9) 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, including apples, durians, pears, bananas, pineapples, and strawberries. 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.SDS of cas: 763-69-9

Ball-and-chain inactivation in a calcium-gated potassium channel was written by Fan, Chen;Sukomon, Nattakan;Flood, Emelie;Rheinberger, Jan;Allen, Toby W.;Nimigean, Crina M.. And the article was included in Nature (London, United Kingdom) in 2020.SDS of cas: 26662-94-2 The following contents are mentioned in the article:

Inactivation is the process by which ion channels terminate ion flux through their pores while the opening stimulus is still present. In neurons, inactivation of both sodium and potassium channels is crucial for the generation of action potentials and regulation of firing frequency. A cytoplasmic domain of either the channel or an accessory subunit is thought to plug the open pore to inactivate the channel via a ‘ball-and-chain’ mechanism. Here we use cryo-electron microscopy to identify the mol. gating mechanism in calcium-activated potassium channels by obtaining structures of the MthK channel from Methanobacterium thermoautotrophicum-a purely calcium-gated and inactivating channel-in a lipid environment. In the absence of Ca²⁺, we obtained a single structure in a closed state, which was shown by atomistic simulations to be highly flexible in lipid bilayers at ambient temperature, with large rocking motions of the gating ring and bending of pore-lining helixes. In Ca²⁺-bound conditions, we obtained several structures, including multiple open-inactivated conformations, further indication of a highly dynamic protein. These different channel conformations are distinguished by rocking of the gating rings with respect to the transmembrane region, indicating symmetry breakage across the channel. Furthermore, in all conformations displaying open channel pores, the N terminus of one subunit of the channel tetramer sticks into the pore and plugs it, with free energy simulations showing that this is a strong interaction. Deletion of this N terminus leads to functionally non-inactivating channels and structures of open states without a pore plug, indicating that this previously unresolved N-terminal peptide is responsible for a ball-and-chain inactivation mechanism. This study involved multiple reactions and reactants, such as (2R,9Z)-1-(((2-Aminoethoxy)(hydroxy)phosphoryl)oxy)-3-(palmitoyloxy)propan-2-yl oleate (cas: 26662-94-2SDS of cas: 26662-94-2).

Volatile organic compound emissions from surface coating facilities: characterization of facilities, estimation of emission rates, and dispersion modeling of off-site impacts was written by Athappan, Annabrabha;Sumitsawan, Sulak;Gangupomu, Roja Haritha;Kositkanawuth, Ketwalee;Parikh, Parthen;Afotey, Benjamin;Sule, Neelesh;Kalidindi, Sahithi Raj;Sattler, Melanie L.;Weatherton, Yvette Pearson. And the article was included in Journal of Environmental Protection in 2013.Computed Properties of C7H14O3 The following contents are mentioned in the article:

Surface coating facilities are major sources of volatile organic compounds (VOCs) in urban areas. These VOCs can contribute to ground-level ozone formation, and many are hazardous air pollutants (HAPs), including xylene, ethylbenzene, and toluene. This project was conducted in order to provide information for updating the Texas Commission on Environmental Quality TCEQ, USA, permit by rule for Surface Coating Facilities. Project objectives were: (1) to develop a database of information regarding surface coating facilities in Texas; (2) to estimate maximum emission rates for various VOC species from surface coating facilities in Texas; (3) to conduct dispersion modeling to estimate off-site impacts from surface coating facilities. The database was developed using 286 TCEQ permit files authorizing surface coating facilities in Texas during 2006 and 2007. The database was designed to include information important for estimating emission rates, and for using as inputs to the dispersion model. Hourly and annual emissions of volatile organic compounds VOCs, particulate matter PM, and exempt solvents ES were calculated for each permitted entity/ company in the database, according to equations given by TCEQ. Dispersion modeling was then conducted for 3 facility configurations worst-case stack height, good practice stack height, and fugitive emissions, for urban and rural dis- persion parameters, for 8-h and 24-h operating scenarios, and for 1-h, 24-h, and annual averaging times, for a total of 36 scenarios. The highest modeled concentrations were for the worst-case stack height, rural dispersion parameters, 24-h operation scenario, and 1-h averaging time. 108 specific chem. species, which are components of surface coatings, were identified as candidates for further health impacts review. This study involved multiple reactions and reactants, such as Ethyl 3-ethoxypropanoate (cas: 763-69-9Computed Properties of C7H14O3).

Ethyl 3-ethoxypropanoate (cas: 763-69-9) 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. 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.Computed Properties of C7H14O3

Phyto-emulsomes as a novel nano-carrier for morine hydrate to combat leukemia: In vitro and pharmacokinetic study was written by Kamel, Rabab;AbouSamra, Mona M.;Afifi, Sherif M.;Galal, Asmaa F.. And the article was included in Journal of Drug Delivery Science and Technology in 2022.Computed Properties of C21H44O5 The following contents are mentioned in the article:

This study tackles the development of morin hydrate-loaded Phyto-Emulsomes (MH-EMs) using 尾-sitosterol as a 鈥瞙eart-friendly 鈥?alternative to cholesterol for curing leukemia. 尾-sitosterol was isolated from the aerial parts of C. pallescens Delile (Compositae). Phyto-Emulsomes were prepared using different ratios of glyceryl monostearate (GMS), phospholipon 80H (P80H) and ss-sitosterol (SS), then, their size, entrapment efficiency, and drug release were evaluated. Among the prepared formulas, MH-EM5 composed of GMS: P80H: SS (2:0.5:0.5) had the highest drug release efficiency (RE = 82.28 卤 1.96%) and the smallest particle size (271.7 卤 4.86 nm) with a uniform distribution. MH-EM5 was subjected to characterization including the micro-morphol. examination using TEM, thermal anal., in addition to biol. evaluation. The biostability of MH-EM5 in serum and bile salts was proved. The potential cytotoxicity of the free drug, MH-EM5 and its corresponding unmedicated formulation against normal oral epithelial cell and acute monocytic leukemia was studied. The results showed a negligible cytotoxicity in normal cells for all tested samples, while, cancer cells had a significant decrease in the cell viability in case of the selected formula (MH-EM5) compared to the corresponding unmedicated one as well as the free drug, at different concentrations up to 300 渭g/mL. Also, the oral bioavailability study proved the significant increase of all measured pharmacokinetic parameters, after a single oral administration of MH-EM5 compared to the free drug suspension. Regarding these findings, phyto-emulsomes can be considered as a safe and promising nanometric delivery system for the oral administration of morin hydrate due to the enhancement of its solubility, oral bioavailability and antitumor efficacy. This study involved multiple reactions and reactants, such as Glyceryl monostearate (cas: 31566-31-1Computed Properties of C21H44O5).

Glyceryl monostearate (cas: 31566-31-1) belongs to esters. Esters typically have a pleasant smell; those of low molecular weight are commonly used as fragrances and are found in essential oils and pheromones. Cyclic esters are called lactones, regardless of whether they are derived from an organic or inorganic acid. One example of an organic lactone is 纬-valerolactone.Computed Properties of C21H44O5

Sustainability in Skin Care: Incorporation of Avocado Peel Extracts in Topical Formulations was written by Ferreira, Sara M.;Fale, Zizina;Santos, Lucia. And the article was included in Molecules in 2022.Safety of Glyceryl monostearate The following contents are mentioned in the article:

The avocado peel is an agro-industrial byproduct that has exhibited a massive increase in its production in the last few years. The reuse and valorisation of this byproduct are essential since its disposal raises environmental concerns. In the present study, ethanolic extracts of avocado peels of the Hass variety were obtained, for three extraction times (1.5 h, 3 h and 4 h) and analyzed for their antioxidant and antibacterial properties. Antioxidant evaluations of the extracts revealed that the extraction time of 1.5 h exhibited the best results amongst the three, with a DPPH inhibition percentage of 93.92 卤 1.29 and an IC₅₀ percentage, the necessary concentration of the extract to inhibit 50% of DPPH, of 37.30 卤 1.00. The antibacterial capacity of the extracts was evaluated and it was revealed that they were able to inhibit the growth and development of bacteria of the Staphylococcus family. The obtained extract was incorporated in two types of cosmetic formulations (oil-in-water and water-in-oil) and their stability was evaluated and compared with formulations containing synthetic preservatives (BHT and phenoxyethanol). The results of the stability evaluation suggest that the avocado peel extract has the potential to be incorporated in both types of emulsions, acting as an antioxidant and antibacterial agent, proving it to be a viable option to reduce/replace the use of synthetic preservatives. Furthermore, the avocado peel extract proved to be more effective and stable in oil-in-water emulsions. These results highlight the possibility of obtaining sustainable cosmetics, significantly reducing the neg. impacts on the environment by the incorporation of extracts sourced from the avocado peel, an interesting source of phenolic compounds, an abundant and low-cost byproduct. This study involved multiple reactions and reactants, such as Glyceryl monostearate (cas: 31566-31-1Safety of Glyceryl monostearate).

Effect of electromagnetic cylinder variable temperature coupling to hot air drying technology on formation of chestnut-like aroma green tea was written by Chen, Jia-yu;Zhang, Ming-ming;Jiang, Yong-wen;Yang, Yan-qin;Yuan, Hai-bo;Liu, Zheng-quan. And the article was included in Xiandai Shipin Keji in 2021.COA of Formula: C15H22O2 The following contents are mentioned in the article:

In order to investigate the effect of electromagnetic cylinder variable temperature coupling hot air drying technol. on the formation of chestnut-like aroma in green tea, the effects of different combinations of drum variable temperature, drying time, and coupling to hot air were investigated. The qual. and quant. analyses of aroma components were implemented by using IR-assisted extraction coupled to headspace solid-phase microextraction (IRAE-HS-SPME) combined with gas chromatog.-mass spectrometry (GC-MS), and the key compounds for chestnut-like fragrance were further screened by multivariate statistical anal. The results showed that the best quality of chestnut-like aroma was obtained when the drying temperature of the electromagnetic drum was 180 掳C/170 掳C/160 掳C, coupling to hot air at 110 掳C maintaining for 6 min. In addition, an effective discriminant model of green tea with chestnut-like aroma was established by partial least squares-discriminant anal. (PLS-DA) (R²Y = 0.997, Q² = 0.774). Based on VIP > 1 and p 鈮?0.05, 27 key differential compounds were screened out. Their distribution was further determined using hierarchical cluster anal. (HCA), and it was found that the contents of 27 volatiles were generally higher in chestnut-like aroma green teas than non-chestnut-like aroma green teas. In addition, the quality of chestnut-like aroma in green teas was influenced by the tenderness of the raw materials, too. Better quality of chestnut-like fragrance was obtained using green tea with a single bud than that with a bud and one leave. In general, as a promising processing technol., the electromagnetic cylinder variable temperature coupling to hot air drying technol. provides theor. reference and tech. support for the processing of chestnut-like green tea.

Iron Catalyzed Hydroformylation of Alkenes under Mild Conditions: Evidence of an Fe(II) Catalyzed Process was written by Pandey, Swechchha;Raj, K. Vipin;Shinde, Dinesh R.;Vanka, Kumar;Kashyap, Varchaswal;Kurungot, Sreekumar;Vinod, C. P.;Chikkali, Samir H.. And the article was included in Journal of the American Chemical Society in 2018.Name: Methyl heptanoate The following contents are mentioned in the article:

Earth abundant, first row transition metals offer a cheap and sustainable alternative to the rare and precious metals. However, utilization of first row metals in catalysis requires harsh reaction conditions, suffers from limited activity, and fails to tolerate functional groups. Reported here is a highly efficient iron catalyzed hydroformylation of alkenes under mild conditions. This protocol operates at 10-30 bar syngas pressure below 100 掳C, utilizes readily available ligands, and applies to an array of olefins. Thus, the iron precursor [HFe(CO)₄]^–[Ph₃PNPPh₃]⁺ in the presence of tri-Ph phosphine catalyzes the hydroformylation of 1-hexene, 1-octene, 1-decene, 1-dodecene, 1-octadecene, trimethoxy(vinyl)silane, trimethyl(vinyl)silane, cardanol, 2,3-dihydrofuran, allyl malonic acid, styrene, 4-methylstyrene, 4-iBu-styrene, 4-tBu-styrene, 4-methoxy styrene, 4-acetoxy styrene, 4-bromo styrene, 4-chloro styrene, 4-vinylbenzonitrile, 4-vinylbenzoic acid, and allyl benzene to corresponding aldehydes in good to excellent yields. Both electron donating and electron withdrawing substituents could be tolerated and excellent conversions. Remarkably, the addition of 1 mol % acetic acid promotes the reaction to completion within 16-24 h. Detailed mechanistic investigations revealed in situ formation of an iron-dihydride complex [H₂Fe(CO)₂(PPh₃)₂] (A) as an active catalytic species. This finding was further supported by cyclic voltammetry investigations and intermediacy of an Fe(0)-Fe(II) species was established. Combined exptl. and computational investigations support the existence of an iron-dihydride as the catalyst resting state, which then follows a Fe(II) based catalytic cycle to produce aldehyde. This study involved multiple reactions and reactants, such as Methyl heptanoate (cas: 106-73-0Name: Methyl heptanoate).

Methyl heptanoate (cas: 106-73-0) 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.
