Comparative study of different extraction processes for hemp (Cannabis sativa) seed oil considering physical, chemical and industrial-scale economic aspects was written by Devi, Vibha;Khanam, Shabina. And the article was included in Journal of Cleaner Production in 2019.Recommanded Product: 2253-73-8 The following contents are mentioned in the article:

Hemp (Cannabis sativa) seed oil is a rare source of nourishment for vegetarian diets due to the unique ratio of ω-6/ω-3 fatty acid as 3:1. It is beneficial for cardiovascular health, skin, hormonal balance, diabetes, etc. These oil benefits encourage the chem. industries for its intensive extraction to accomplish the quantity and quality of the product. Despite being various processes i.e. supercritical fluid extraction, Soxhlet, percolation, ultrasonication, pyrolysis, pretreatment processes etc., none of above is the best in all aspects. Therefore, the present study investigates different extraction processes for hemp oil and compared its industrial-scale economic assessment, extraction yield, oil compositions and physico-chem. properties. Central composite design was employed to optimize the parameters of supercritical fluid extraction and ultrasonication processes. Quadratic models (P < 0.05) for both processes were developed with satisfactory R² (>0.93). The maximum yield of 37.30% was estimated through ultrasonication treated Soxhlet process. Gas chromatog.-mass spectrometry demonstrated Soxhlet as the best-suited process while offering the optimum ω-6/ω-3 ratio. Further, gas chromatog.-mass spectrometry of hemp bio-oil obtained through pyrolysis identified the volatile and flammable materials to assure its suitability as bio-fuel. Economic analyses for different processes revealed supercritical fluid extraction as the most beneficial followed by Soxhlet, ultrasonication, ultrasonication treated Soxhlet and Soxhlet treated ultrasonication. This study involved multiple reactions and reactants, such as Isopropylisothiocyanate (cas: 2253-73-8Recommanded Product: 2253-73-8).

Isopropylisothiocyanate (cas: 2253-73-8) belongs to esters. 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. 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.Recommanded Product: 2253-73-8

And the article was included in International Journal of Pharma and Bio Sciences in 2017.Synthetic Route of C20H40O2 The following contents are mentioned in the article:

Male infertility is a world-wide medical and social problem. In Ayurveda, single or multiple herbs (polyherbal) are used for the treatment. The concept of polyherbalism is to achieve greater therapeutic efficacy. The active phytochem. constituents of individual plants are insufficient to achieve the desirable therapeutic effects. When combining the multiple herbs in a particular ratio, it will give a better therapeutic effect and reduce the toxicity. N-Miracle, a polyherbal formulation, which was prepared by the combination of five medicinal plants and selenium having diversified pharmacol. effect, however, the anti-infertility effect of the combination of the above plants are not yet carried out. Hence, the present study has been designed with the purpose of identifying the active principles of methanolic extract of N-Miracle (Polyherbal formulation) by UV-Visible spectrophotometer, FTIR, TLC, HPLC, and GC-MS anal. UV-Visible spectrum revealed the presence of phenolic compounds and flavonoid compounds in the range of 220 nm to 1100 nm. FTIR spectrum unveiled the presence of phenol, alkane, carboxylic acid, aromatic compound, aliphatic amines and halogen compounds TLC of methanolic extract of N-Miracle (Polyherbal formulation) revealed the presence flavonoid compound namely isoquercetin. HPLC anal. of the methanolic extract of N-Miracle (Polyherbal formulation) showed the presence of polyphenols and flavonoid compound at RT 5.541, RT 13.060, and RT 32.028. GC-MS screening revealed the presence of alc., fatty alc., alkane, phytol, and fatty acid Me esters groups.

A coarse-grained model of dimethyl sulfoxide for molecular dynamics simulations with lipid membranes was written by Shobhna;Kumari, Monika;Kashyap, Hemant K.. And the article was included in Journal of Chemical Physics in 2020.Application In Synthesis of (2R,9Z)-1-(((2-Aminoethoxy)(hydroxy)phosphoryl)oxy)-3-(palmitoyloxy)propan-2-yl oleate The following contents are mentioned in the article:

Enhanced permeability of biomembranes upon the application of small amphiphiles is of vital importance to biologists and pharmacists, as their physiochem. interactions open new pathways for transdermal drug transportation and administration. Amphiphilic DMSO is known to alter biomembrane permeability. Atomistic simulation-based studies to explore the impact of amphiphilic mols. on the model lipid membranes are of immense importance. These studies provide mol. details on how the membrane phys. properties, such as fluidity and thickness, are modulated by amphiphile-lipid interactions. However, such approaches are usually limited to short simulation time and length scales. To circumvent such limitations, the use of coarse-grained (CG) models is a current computational strategy. The authors have presented a new CG force-field for DMSO for mol. dynamics (MD) simulations. The model is designed to reproduce exptl. bulk properties of DMSO and its aqueous mixtures, mol.-level structure of liquid DMSO, and the phase transfer energy of a single DMSO mol. from the aqueous phase to the lipid bilayer hydrophobic interior. The current CG DMSO model successfully mimics the structural variation in phospholipid bilayer systems (1-palmitoyl-2-oleoyl-sn-glycero-3-phosphocholine and 1-palmitoyl-2-oleoyl-sn-glycero-3-phosphoethanolamine) including alteration in bilayer thickness, lipid tail ordering, lipid lateral packing, and electron d. profiles at various DMSO concentrations when compared to those obtained from parallel atomistic simulations.

Fucose-Galactose Polymers Inhibit Cholera Toxin Binding to Fucosylated Structures and Galactose-Dependent Intoxication of Human Enteroids was written by Cervin, Jakob;Boucher, Andrew;Youn, Gyusaang;Bjoerklund, Per;Wallenius, Ville;Mottram, Lynda;Sampson, Nicole S.;Yrlid, Ulf. And the article was included in ACS Infectious Diseases in 2020.Synthetic Route of C16H22O11 The following contents are mentioned in the article:

A promising strategy to limit cholera severity involves blockers mimicking the canonical cholera toxin ligand (CT) ganglioside GM1. However, to date the efficacies of most of these blockers have been evaluated in noncellular systems that lack ligands other than GM1. Importantly, the CT B subunit (CTB) has a noncanonical site that binds fucosylated structures, which in contrast to GM1 are highly expressed in the human intestine. Here we evaluate the capacity of norbornene polymers displaying galactose and/or fucose to block CTB binding to immobilized protein-linked glycan structures and also to primary human and murine small intestine epithelial cells (SI ECs). We show that the binding of CTB to human SI ECs is largely dependent on the noncanonical binding site, and interference with the canonical site has a limited effect while the opposite is observed with murine SI ECs. The galactose-fucose polymer blocks binding to fucosylated glycans but not to GM1. However, the preincubation of CT with the galactose-fucose polymer only partially blocks toxic effects on cultured human enteroid cells, while preincubation with GM1 completely blocks CT-mediated secretion. Our results support a model whereby the binding of fucose to the noncanonical site places CT in close proximity to scarcely expressed galactose receptors such as GM1 to enable binding via the canonical site leading to CT internalization and intoxication. Our finding also highlights the importance of complementing CTB binding studies with functional intoxication studies when assessing the efficacy inhibitors of CT. This study involved multiple reactions and reactants, such as (2S,3R,4S,5R,6R)-6-(Acetoxymethyl)tetrahydro-2H-pyran-2,3,4,5-tetrayl tetraacetate (cas: 604-69-3Synthetic Route of C16H22O11).

Direct Immersion-Solid-Phase Microextraction Coupled to Gas Chromatography-Mass Spectrometry and Response Surface Methodology for Nontarget Screening of (Semi-) Volatile Migrants from Food Contact Materials was written by Su, Qi-Zhi;Vera, Paula;Nerin, Cristina. And the article was included in Analytical Chemistry (Washington, DC, United States) in 2020.Category: esters-buliding-blocks The following contents are mentioned in the article:

Toward a more rigorous inspection of food contact materials, the importance of sample preparation for nontarget screening should be addressed. Direct immersion-solid-phase microextraction coupled to gas chromatog. mass spectrometry (DI-SPME-GC-MS) was optimized for nontarget screening of migrants in 3% acetic acid, 10% ethanol, and 95% ethanol food simulants by response surface methodol. (RSM) in the present study. Optimum conditions were DVB/CAR/PDMS fiber, no pH adjustment for 10% and 95% ethanol simulant but pH adjustment to 7 for 3% acetic acid simulant, no salt addition, 5 min preincubation, 55 min extraction at 70°C, and 8 min desorption at 250°C. In addition, 9.5 times dilution of 95% ethanol samples prior to extraction was required. pH modification of 3% acetic acid samples was found to be critical for the extraction of amines. The proposed methodol. was then evaluated by determining the limit of detection (LOD) as well as repeatability of 35 food contact materials-related substances. Except for those amines and diols which have a relatively high LOD, the LODs of the rest of the substances were 0.1-14.1μg/kg with a precision of 1.9-23.0% in 10% ethanol and were 0.1-20.2μg/kg with a precision of 2.5-19.6% in 3% acetic acid simulant. The LOD and precision in 95% ethanol simulant were 0.7-163.7μg/kg and 1.4-26.8%, resp. The proposed method can be applied for an overall screening of migrants from these three simulants at even trace levels, though attention should be paid to some specific analytes, e.g., diols and amines, which could have a high LOD and toxicity. This study involved multiple reactions and reactants, such as Diphenyl carbonate (cas: 102-09-0Category: esters-buliding-blocks).

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

Development of trimethyl chitosan coated nanostructure lipid carriers to enhance the brain targeting capacity of ceftriaxone was written by Padhi, Swarupanjali;Mazumder, Rupa;Bisth, Shradha. And the article was included in Journal of Dispersion Science and Technology.Reference of 31566-31-1 The following contents are mentioned in the article:

Cationic nanostructured lipid carriers were devised to improve the biodistribution of the drug in the CNS. Especially, the delivery of antibiotics via uninflamed meninges at various stages of infection is the most challenging part of the treatment regimen. The ceftriaxone loaded nanostructured lipid carriers (NLC-CEFs) were formulated using glyceryl monostearate and capryol90 and the resulting NLC-CEFs were coated with tri-Me chitosan (NLC-CEFs-TMC) to increase the cellular uptake of the drug. The TMC was synthesized from chitosan and its formation was confirmed by XRD, FTIR, DSC, and H1 NMR analyses. The freeze-dried NLC-CEFs and the NLC-CEFs-TMC formed, were evaluated by FTIR, DSC, XRD, SEM, and zeta potential analyses. The rat model was used to study the biodistribution of the drug in brain and confirm the potential delivery of drug in NLC-CEFs-TMC carriers through blood brain barrier. It was found to increase by 10.51 times compared to the drug solution when administered through IV and collected after 8 h. The brain enhancement factor was found to be, 5.86 and 7.95 resp. for NLC-CEFs and NLC-CEFs-TMC collected after 8 h. The brain targeting index was found to be 0.29 ± 0.02, 0.50 ± 0.04 and 0.029 ± 0.007 for NLC-CEFs, NLC-CEFs-TMC, and CEF solution The highest brain targeting index and brain enhancement ratio was achieved by NLC-CEFs-TMC. Success of these lipid dosage forms may be attributed to the lipophilic nature of the NLCs, which is similar to that of meninges and another cause may be the increase in the uptake of cationic NLCs by neg. charged CNS membrane. This study involved multiple reactions and reactants, such as Glyceryl monostearate (cas: 31566-31-1Reference of 31566-31-1).

Glyceryl monostearate (cas: 31566-31-1) belongs to esters. Esters are also usually derived from carboxylic acids.

And the article was included in Journal of Pharmaceutical and Biomedical Analysis in 2017.Application In Synthesis of Ethyl 3-ethoxypropanoate The following contents are mentioned in the article:

The determination of extractable profiles for single-use technologies represents an important aspect of pharmaceutical production to minimize any possible compromise in drug product quality or potential risk to patients by identifying substances that may potentially leach from such devices. An approach for the extractable assessment of prefilled syringes, a promising alternative for parenteral administration of pharmaceutical products, is described herein. Four extraction solvents were selected: a mixture 2-propanol:water (1:1), was intended to represent aggressive conditions to extract a broad spectrum of extractables, including organic additives and substances which are poorly water-soluble Extractions with buffers at three different working pH values spanning a range standardly used in pharmaceutical formulations were also evaluated to identify substances that require specific conditions for their extraction due to their individual chem. properties. Syringes from two different brands were analyzed along with their corresponding plunger stoppers. Syringes were extracted at 40 °C for 4 days, the plunger stoppers were extracted with 2-propanol at 70 °C for 24 h according to ISO 10993-12:2012. Extractables were identified by UHPLC-MS on a quadrupole time of flight instrument using a non-targeted discovery strategy. A total of 25 compounds were identified, mostly polymer additives and their degradation products. The presented methodol. represents a reference point for further studies focused on the characterization of extractables and leachables from prefilled syringes. This study involved multiple reactions and reactants, such as Ethyl 3-ethoxypropanoate (cas: 763-69-9Application In Synthesis of Ethyl 3-ethoxypropanoate).

An alternative route to cyclic terpenes by reductive cyclization in iridoid biosynthesis was written by Geu-Flores, Fernando;Sherden, Nathaniel H.;Courdavault, Vincent;Burlat, Vincent;Glenn, Weslee S.;Wu, Cen;Nims, Ezekiel;Cui, Yuehua;O’Connor, Sarah E.. And the article was included in Nature (London, United Kingdom) in 2012.Reference of 37905-02-5 The following contents are mentioned in the article:

The iridoids comprise a large family of distinctive bicyclic monoterpenes that possess a wide range of pharmacol. activities, including anticancer, anti-inflammatory, antifungal and antibacterial activities. Addnl., certain iridoids are used as sex pheromones in agriculturally important species of aphids, a fact that has underpinned innovative and integrated pest management strategies. To harness the biotechnol. potential of this natural product class, the enzymes involved in the biosynthetic pathway must be elucidated. Here we report the discovery of iridoid synthase, a plant-derived enzyme that generates the iridoid ring scaffold, as evidenced by biochem. assays, gene silencing, coexpression anal. and localization studies. In contrast to all known monoterpene cyclases, which use geranyl diphosphate as substrate and invoke a cationic intermediate, iridoid synthase uses the linear monoterpene 10-oxogeranial as substrate and probably couples an initial NAD(P)H-dependent reduction step with a subsequent cyclization step via a Diels-Alder cycloaddition or a Michael addition Our results illustrate how a short-chain reductase was recruited as cyclase for the production of iridoids in medicinal plants. Furthermore, we highlight the prospects of using unrelated reductases to generate artificial cyclic scaffolds. Beyond the recognition of an alternative biochem. mechanism for the biosynthesis of cyclic terpenes, we anticipate that our work will enable the large-scale heterologous production of iridoids in plants and microorganisms for agricultural and pharmaceutical applications. This study involved multiple reactions and reactants, such as (2E,6E)-3,7-Dimethyl-8-oxoocta-2,6-dien-1-yl acetate (cas: 37905-02-5Reference of 37905-02-5).

Organic chem. pollutants in atm. particulate matter (PM) have a potential toxicity hazard resulting in human responses that vary from no discernible effect to premature death. The formation and sources of PM also affect air quality of metropolitan areas as well as climate change. The new developments and industrial activities in the Middle East, especially Saudi Arabia, are expected to contribute to the natural, regional, and anthropogenic input sources of organic matter (OM). Here we report the occurrence, concentrations and sources of organic tracers, including n-alkanes, polycyclic aromatic hydrocarbons (PAHs), plasticizers, and petroleum biomarkers, in ambient atm. PM from the city of Dhahran, Saudi Arabia. The major compounds were unresolved complex mixtures (UCM) of branched and cyclic hydrocarbons (489 ± 296 ng m^-3), plasticizers (131 ± 119 ng m^-3 for Ph phosphates, 87 ± 42 ng m^-3 for phthalates), n-alkanes (73 ± 53 ng m^-3), hopane biomarkers (11 ± 8 ng m^-3), n-alkanones (6.7 ± 6.3 ng m^-3), PAHs (2.0 ± 2.1 ng m^-3), n-alkanols (1.2 ± 1.2 ng m^-3), sterane biomarkers (0.4 ± 0.3 ng m^-3), and sterols (0.5 ± 0.4 ng m^-3). Obviously, UCM and plasticizers were the major components (56 ± 9% and 26 ± 10% of the total extracts, resp.) in the PM of Dhahran, which might have adverse public health effects. The major sources of this OM are emissions from industrial factories north of the city, plastics and biomass burning, and petroleum product combustion (traffic/refining).

Optimization of fermentation conditions of green tea wine and changes in its main components during fermentation was written by Zhao, Xiao-yue;Xu, Huai-de;Yang, Rong-xiang. And the article was included in Shipin Kexue (Beijing, China) in 2014.Category: esters-buliding-blocks The following contents are mentioned in the article:

The fermentation process of green tea wine was optimized, and the changes in polyphenols, catechins and aroma components during fermentation were investiated. Orthogonal array experiments were used to optimize the fermentation process. The changes in catechins and aroma components were determined by high performance liquid chromatog. (HPLC) and gas chromatog.-mass spectrometry (GC-MS). The optimal fermentation parameters were determined as follows: 4 g/L green tea infusion with 20% glucose and 50 g/L honey added, 5 g/L wine yeast inoculum size, and fermentation at 28°C for 10 days. The contents of six catechins were increased during fermentation Specifically, the contents of (-)-epigallocatechin (EGC), (-)-gallocatechin gallate (GCG), epicatechin gallate (ECG), and epicatechin (EC) were slightly increased; however, the contents of catechin (C) and epigallocatechin-3-gallate catechin (EGCGC) were increased by 10.88 and 17.33-folds, resp. These results indicate that the increase of catechins plays an important role in the health-promoting function of green tea wine. There were 87, 88 and 94 aroma components in the wine at the initial and the last stages of fermentation and the aged wine, which accounted for 92.93%, 98.26% and 91.87% of the total volatile components, resp. The significant differences in the types and amounts of aroma components indicate the transition from the tea flavor to the wine aroma components. Green tea can be fermented into wine; the health-promoting components (catechins) of green tea are increased to different extents and the green tea wine is mellow.
