Salix variegata Franch. is a riparian shrub species that can tolerate long-term complete submergence; however, the mol. mechanisms underlying this trait remain to be elucidated. In this study, we subjected S. variegata plants to complete submergence for 60 d and collected stems to perform transcriptomic and metabolomic analyses, as well as quant. reverse transcription-polymerase chain reaction (qRT-PCR) assays. Results revealed that photosynthesis and the response to light stimulus were inhibited during submergence and recovered after desubmergence. Ethylene and abscisic acid (ABA) signaling could be important for the long-term submergence tolerance of S. variegata. Jasmonic acid (JA) signaling also participated in the response to submergence. Raffinose family oligosaccharides, highly unsaturated fatty acids, and specific stress-related amino acids accumulated in response to submergence, indicating that they may protect plants from submergence damage, as they do in response to other abiotic stressors. Several organic acids were produced in S. variegata plants after submergence, which may facilitate coping with the toxicity induced by submergence. After long-term submergence, cell wall reorganization and phenylpropanoid metabolic processes (the synthesis of specific phenolics and flavonoids) were activated, which may contribute to long-term S. variegata submergence tolerance; however, the detailed mechanisms require further investigation. Several transcription factors (TFs), such as MYB, continuously responded to submergence, indicating that they may play important roles in the responses and adaptation to submergence. Genes related to oxidative stress tolerance were specifically expressed after desubmergence, potentially contributing to recovery of S. variegata plants within a short period of time. This study involved multiple reactions and reactants, such as Bisdemethoxycurcumin (cas: 33171-05-0HPLC of Formula: 33171-05-0).

A number of new nido-carboranyl amidines 10-R(CH₂)_nNHC(Et):HN-7,8-C₂B₉H₁₁ (n = 2, R = OH, OMe, and NMe₂; n = 3, R = OH) were synthesized by the nucleophilic addition of amino alcs. and N,N-dimethylethylenediamine to the highly activated -CN⁺ – triple bond of the 10-propionitrilium derivative of nido-carborane. A similar reaction of 10-EtCN-7,8-C₂B₉H₁₁ with ethylenediamine unexpectedly resulted in the cleavage of the CN bond to form the ammonium derivative 10-H₃N-7,8-C₂B₉H₁₁. The complexation of the synthesized carboranyl amidines 10-MeO(CH₂)₂NHC(Et):HN-7,8-C₂B₉H₁₁ and 10-Me₂N(CH₂)₂NHC(Et):HN-7,8-C₂B₉H₁₁ with Ni and Pd phosphine complexes [(Ph₃P)₂MCl₂] (M = Ni, Pd) was studied. The reactions with 10-MeO(CH₂)₂NHC(Et)HN-7,8-C₂B₉H₁₁ result in half-sandwiched metallacarborane complexes with the retention of one PPh₃ ligand [3-Ph₃P-3-(8-MeOCH₂CH₂N:C(Et)NH)-3,1,2-MC₂B₉H₁₀], while the reactions with 10-Me₂N(CH₂)₂NHC(Et):HN-7,8-C₂B₉H₁₁ proceed with the complete loss of the phosphine ligands and give complexes with the η⁵:κ²(N,N’)-coordinated carboranyl amidine ligand [3,3-(8-Me₂NCH₂CH₂N:C(Et)NH)-3,1,2-MC₂B₉H₁₀].

Synthesis and property of alkyl dioxyethyl α-D-xyloside was written by Wu, Xiubing;Kuang, Na;Chen, Langqiu;Fan, Yulin;Fu, Fang;Li, Jiping;Zhang, Jing. And the article was included in Journal of Molecular Liquids in 2020.Synthetic Route of C10H22O3 The following contents are mentioned in the article:

Due to the inherent defects of the long alkyl chain in the related hydrophilicity and water solubility, alkyl α-D-xylosides (7) had hardly the practical application as sugar-based surfactants and should be reconstructed to obtain alkyl dioxyethyl α-D-xylosides (5) with dioxyethylene fragment (-(OCH₂CH₂)_2-) as the hydrophilic spacer to increase the related TPSA value. With D-xylose as the raw material, 1,2-cis alkyl dioxyethyl α-D-xylosides (5a-5f, n = 6-12) were stereoselectively synthesized. Their physicochem. properties including water solubility, surface tension, foamability, emulsification, thermotropic liquid crystal, and hygroscopicity had been investigated. Their water solubility was found to decrease gradually whereas their calculated HLB numbers were 14.72 → 11.67 (n = 6 → 12) with increasing alkyl chain length (n). Dodecyl dioxyethyl α-D-xyloside (5f) had not water solubility because the HLB number was low. Furthermore, their CMC values decreased with increasing the alkyl chain length, and the CMC value of decyl dioxyethyl α-D-xyloside (5e) was as low as 9.21 x 10^-5 mol·L^-1. Octyl dioxyethyl α-D-xyloside (5c) had the lowest surface tension (27.25 mN·m^-1) at the CMC. Both of nonyl and decyl dioxyethyl α-D-xylosides (5d & 5e) possessed good foaming power and foam stability. Decyl dioxyethyl α-D-xyloside (5e) had the strongest emulsifying property either in the toluene/water system or in the octane/water system. Nonyl dioxyethyl α-D-xylosides (5d) had the most stylish SA texture. Hexyl dioxyethyl α-D-xyloside (5a) possessed the strongest hygroscopicity. Therefore, the alkyl dioxyethyl α-D-xylosides as a class of novel sugar-based surfactants will be widely considered as promising candidates for various practical applications. This study involved multiple reactions and reactants, such as 2-(2-(Hexyloxy)ethoxy)ethanol (cas: 112-59-4Synthetic Route of C10H22O3).

2-(2-(Hexyloxy)ethoxy)ethanol (cas: 112-59-4) belongs to ethers. 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. 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.

Estrogenic activity of lignin-derivable alternatives to bisphenol A assessed via molecular docking simulations was written by Amitrano, Alice;Mahajan, Jignesh S.;Korley, LaShanda T. J.;Epps, Thomas H. III. And the article was included in RSC Advances in 2021.Category: ethers-buliding-blocks The following contents are mentioned in the article:

Lignin-derivable bisphenols are potential alternatives to bisphenol A (BPA), a suspected endocrine disruptor; however, a greater understanding of structure-activity relationships (SARs) associated with such lignin-derivable building blocks is necessary to move replacement efforts forward. This study focuses on the prediction of bisphenol estrogenic activity (EA) to inform the design of potentially safer BPA alternatives. To achieve this goal, the binding affinities to estrogen receptor alpha (ERα) of lignin-derivable bisphenols were calculated via mol. docking simulations and correlated to median effective concentration (EC50) values using an empirical correlation curve created from known EC50 values and binding affinities of com. (bis)phenols. Based on the correlation curve, lignin-derivable bisphenols with binding affinities weaker than ∼-6.0 kcal mol-1 were expected to exhibit no EA, and further anal. suggested that having two methoxy groups on an aromatic ring of the bio-derivable bisphenol was largely responsible for the reduction in binding to ERα. Such dimethoxy aromatics are readily sourced from the depolymerization of hardwood biomass. Addnl., bulkier substituents on the bridging carbon of lignin-bisphenols, like di-Et or dimethoxy, were shown to weaken binding to ERα. And, as the bio-derivable aromatics maintain major structural similarities to BPA, the resultant polymeric materials should possess comparable/equiv thermal (e.g., glass transition temperatures, thermal decomposition temperatures) and mech. (e.g., tensile strength, modulus) properties to those of polymers derived from BPA. Hence, the SARs established in this work can facilitate the development of sustainable polymers that maintain the performance of existing BPA-based materials while simultaneously reducing estrogenic potential. This study involved multiple reactions and reactants, such as 4-Benzyloxyphenol (cas: 103-16-2Category: ethers-buliding-blocks).

The electrical pulse application enhances intra-cellular localization and potentiates cytotoxicity of curcumin in breast cancer cells was written by Bazzolo, B.;Mittal, L.;Sieni, E.;Piovan, A.;Filippini, R.;Conconi, M. T.;Camarillo, I. G.;Sundararajan, R.. And the article was included in Bioelectrochemistry in 2021.COA of Formula: C19H16O4 The following contents are mentioned in the article:

Breast cancer is the most common cancer of women, and fifth leading cause of mortality worldwide. Existing breast cancer regimens are costly and produce severe side effects. This highlights a need for the development of efficient novel therapies, which are cost effective and limit side effects. An elec. pulse (EP)-based chemo therapy, known as electrochemotherapy (ECT) using the natural compound curcumin could be an effective alternative. ECT is a non-surgical modality, which produces excellent anti-tumor efficacy at small drug concentrations due to increased uptake of drugs. In clinics, ECT is shown to be effective in treating advanced, recurrent, and metastatic breast cancers, which are refractory to multiple modalities. ECT with curcumin triggers apoptotic cell death in breast cancer cells and could be an effective alternative, due to curcumin’s low cost and reduced side-effects. However, there is a lack of studies quantifying the uptake of curcumin in response to EP application. Towards this, we determined the uptake of different curcuminoids (curcumin, desmethoxycurcumin, and bisdemethoxycurcumin) upon EP application and their impact on cell cytotoxicity. Addnl., we studied the combined effect of calcium chloride (CaCl₂) and a curcuminoids (Cur) mixture, based on initial studies suggesting calcium electroporation as a potential inexpensive anti-cancer treatment. Our results indicate EP with Cur increases cellular uptake, cell shrinkage, and cytotoxicity. The EP + Cur resulted in the highest uptake of the bisdemethoxycurcumin. Further, EP also potentiated the cytotoxicity of CaCl₂ and of the Cur and CaCl₂ combination against breast cancer cells and caused apoptosis. Our preliminary data pave the way to further studies on Cur and CaCl₂ combination treating breast cancer.

Response to isopropanol or ionic/non-ionic surfactant in the competitive imbibition of water and alkane into calcium carbonate coating structures was written by Ridgway, Cathy J.;Schoelkopf, Joachim;Gane, Patrick A. C.. And the article was included in Nordic Pulp & Paper Research Journal in 2011.Name: 2-(2-(Hexyloxy)ethoxy)ethanol The following contents are mentioned in the article:

This work explores the relationship between polar and non-polar liquids and their interaction with typical porous coating structures, consisting of 100% dispersed calcium carbonate. The effects of addnl. agents, i.e. isopropanol and ionic/non-ionic surfactant are investigated. These agents are currently being employed and developed for the printing industry. Absorption rates into compressed tablets of ground calcium carbonate, with and without the presence of latex, are observed Polyacrylate dispersant, used in manufacture, renders the pigment surface both hydrophilic and hygroscopic, and therefore controls the differential dynamic wetting characteristics of the porous structure for either polar or non-polar liquids In competition with non-polar hexadecane saturating the pore structure of a latex-free sample, polar water displaces the non-polar liquid instantaneously, causing disintegration of the packed porous structure. In the presence of latex binder, however, the structurally destructive pressure is contained, and the uptake of polar water is retarded. The required pre-wetting action of water vapor diffusion on the carbonate polyacrylate dispersant pigment surface is considered to be an integral part of the successful competition between oil and water in the offset printing process, as non-polar oil absorbs steadily into a water pre-saturated structure. Addnl., isopropanol likely promotes miscibility and emulsification more so than ionic/non-ionic surfactant. This behavior possibly relates to the comparative mol. weights of the agents which differentiate their surface energy modifying mechanism from those of the ionic pigment dispersant and binder stabilizers/carboxylation. The use of addnl. agents enables potentially a more homogeneous response to the competitive imbibition environment within the coating structure. This study involved multiple reactions and reactants, such as 2-(2-(Hexyloxy)ethoxy)ethanol (cas: 112-59-4Name: 2-(2-(Hexyloxy)ethoxy)ethanol).

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. 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.Name: 2-(2-(Hexyloxy)ethoxy)ethanol

Estimating Preferred Alkane Carbon Numbers of Nonionic Surfactants in Normalized Hydrophilic-Lipophilic Deviation Theory from Dissipative Particle Dynamics Modeling was written by Ren, Hua;Zhang, Qiuyu;Zhang, Baoliang;Song, Qingfei. And the article was included in Journal of Physical Chemistry B in 2022.Safety of 2-(2-(Hexyloxy)ethoxy)ethanol The following contents are mentioned in the article:

The preferred alkane carbon number (PACN) in the normalized hydrophilic-lipophilic deviation (HLD_N) theory is a numerical parameter and a transferable scale to characterize the amphiphilicity of surfactants, which is usually measured exptl. using the fish diagram or phase inversion temperature (PIT) methods, and the exptl. measurement can only be applied to existing surfactants. Here, for the first time, we propose a procedure to estimate the PACN of C_iE_j nonionic surfactants directly from dissipative particle dynamics (DPD) simulation. The procedure leverages the method of moment concept to quant. evaluate the bending tendency of nonionic surfactant monolayers by calculating the torque d. Seven nonionic surfactants, C_iE_j (C₆E₂, C₆E₃, C₈E₃, C₈E₄, C₁₀E₄, C₁₂E₄, and C₁₂E₅), with known PACNs are modeled. Two surfactants, C₁₀E₄ and C₆E₂, were first selected to train and test the interaction parameters, and the relationship between interaction parameters and torque d. was mapped for the C₁₀E₄-octane-water system using the artificial neural network (ANN) fitting approach to derive the interaction parameters giving zero torque d., then the interaction parameters were tested in the C₆E₂-dodecane-water system to get the final tuned interaction parameters for PACN estimation With this procedure, we reproduce the PACN values and their trend of seven nonionic surfactants with reasonable accuracy, which opens the door for quant. comparison of surfactant amphiphilicity and surfactant classification in silico using the PACN as a transferable scale.

Bisdemethoxycurcumin sensitizes the response of cisplatin resistant non-small cell lung carcinoma cell lines by activating apoptosis and autophagy was written by Klingseisen, Verena;Slanovc, Julia;Regouc, Manuel;Hrzenjak, Andelko.

Lung cancer belongs to the most frequent and deadliest cancer types worldwide, non-small cell lung carcinoma (NSCLC) being the most frequent type. Development of chemoresistance in NSCLC patients is common and responsible for bad outcome. Curcuminoids are naturally occurring substances with prominent cytotoxic effects in different cancer cells. Here we analyzed influence of bisdemethoxycurcumin (BDMC) on phenotype and mol. mechanisms in cisplatin-sensitive NSCLC cell lines (A549 and H460) and their cisplatin-resistant counterparts. NSCLC cell lines were exposed to BDMC and analyzed by cell viability, proliferation, and motility assays, as well as fluorescence-activated cell sorting. Immunoblotting was assessed to detect apoptosis and autophagy. Colony-formation assay and multicellular tumor spheroid model were used to investigate the effects of BDMC. Expression levels of different Hedgehog-pathway genes were determined by RT-qPCR anal. We identified substantial cytotoxic effects of BDMC on NSCLC cells in general and on cisplatin-resistant NSCLC cells in special. BDMC markedly decreased the cell viability by inducing apoptosis and autophagy in a cell-type specific manner. BDMC emphasized cisplatin-induced cell death and inhibited cell cycle progression of cisplatin-resistant NSCLC cells. Scratch-closure, colony formation, and multicellular spheroid growth in cisplatin-resistant NSCLC cell lines were inhibited by BDMC. Expression profile analyses of different Hedgehog-pathway regulatory genes showed that Gli1, the mean transcriptional regulator of this pathway, was markedly decreased upon the BDMC treatment, this decrement being most prominent in cisplatin-resistant cells. Our data identified BDMC as a potent substance that may be suitable for combined cisplatin-based therapy in cisplatin-resistant subpopulation of NSCLC patients.

Lignin is an abundant source of aromatics, and the depolymerization of lignin provides significant potential for producing high-value chems. Selective hydrogenolysis of the C-O ether bond in lignin is an important strategy for the production of fuels and chem. feedstocks. In our study, catalytic hydrogenolysis of lignin model compounds (β-O-4, α-O-4 and 4-O-5 model compounds) over Ni₃S₂-CS catalysts was investigated. Hence, an array of 2D carbon nanostructure Ni₃S₂-CSs-X-Y derived catalysts were produced using different compositions at different temperatures (X = 0 mg, 0.2 mg, 0.4 mg, 0.6 mg, and 0.8 mg; Y = 600°C, 700°C, 800°C, and 900°C) were prepared and applied for hydrogenolysis of lignin model compounds and depolymerization of alk. lignin. The highest conversion of lignin model compounds (β-O-4 model compound) was up to 100% and the yield of the obtained corresponding ethylbenzene and phenol could achieve 92% and 86%, resp., over the optimal Ni₃S₂-CSs-0.4-700 catalyst in iPrOH at 260°C without external H₂. The 2D carbon nanostructure catalysts performed a good dispersion on the surface of the carbon nanosheets, which facilitated the cleavage of the lignin ether bonds. The physicochem. characterization studies were carried out by means of XRD, SEM, TEM, H₂-TPR, NH₃-TPD, Raman and XPS analyses. Based on the optimal reaction conditions (260°C, 4 h, 2.0 MPa N₂), various model compounds (β-O-4, α-O-4 and 4-O-5 model compounds) could also be effectively hydrotreated to produce the corresponding aromatic products. Furthermore, the optimal Ni₃S₂-CSs-0.4-700 catalyst could be carried out in the next five consecutive cycle experiments with a slight decrease in the transformation of lignin model compounds This study involved multiple reactions and reactants, such as 4-Benzyloxyphenol (cas: 103-16-2SDS of cas: 103-16-2).
