Influence of L. thermotolerans and S. cerevisiae commercial yeast sequential inoculation on aroma composition of red wines (Cv Trnjak, Babic, Blatina and Frankovka) was written by Korenika, Ana-Marija Jagatic;Tomaz, Ivana;Preiner, Darko;Lavric, Marina;Simic, Branimir;Jeromel, Ana. And the article was included in Fermentation in 2021.Reference of 2380-78-1 The following contents are mentioned in the article:

Even though Saccharomyces cerevisiae starter cultures are still largely used nowadays, the non-Saccharomyces contribution is re-evaluated, showing pos. enol. characteristics. Among them, Lachancea thermotolerans is one of the key yeast species that are desired for their contribution to wine sensory characteristics. The main goal of this work was to explore the impact of L. thermotolerans com. yeast strain used in sequential inoculation with S. cerevisiae com. yeast on the main enol. parameters and volatile aroma profile of Trnjak, BabiC, Blatina, and Frankovka red wines and compare it with wines produced by the use of S. cerevisiae com. yeast strain. In all sequential fermented wines, lactic acid concentrations were significantly higher, ranging from 0.20 mg/L in Trnjak up to 0.92 mg/L in Frankovka wines, while reducing alc. levels from 0.1% volume/volume in Trnjak up to 0.9% volume/volume in Frankovka wines. Among volatile compounds, a significant increase of Et lactate and iso-Bu acetate, geraniol, and geranyl acetate was detected in all wines made by use of L. thermotolerans. In BabiC wines, the strongest influence of sequential fermentation was connected with higher total terpenes and total ester concentrations, while Trnjak sequentially fermented wines stood up with higher total aldehyde, volatile phenol, and total lactone concentrations Control wines, regardless of variety, stood up with higher concentrations of total higher alcs., especially isoamyl alc. The present work contributed to a better understanding of the fermentation possibilities of selected non-Saccharomyces strains in the overall red wine quality modeling. This study involved multiple reactions and reactants, such as 4-Hydroxy-3-methoxyphenethanol (cas: 2380-78-1Reference of 2380-78-1).

The impact of olive oil compounds on the metabolic reprogramming of cutaneous melanoma cell models was written by Brito, Cheila;Tomas, Ana;Silva, Sandra;Bronze, Maria Rosario;Serra, Ana Teresa;Pojo, Marta. And the article was included in Molecules in 2021.Synthetic Route of C9H12O3 The following contents are mentioned in the article:

Cutaneous melanoma is the deadliest type of skin cancer, characterized by a high mol. and metabolic heterogeneity which contributes to therapy resistance. Despite advances in treatment, more efficient therapies are needed. Olive oil compounds have been described as having anti-cancer properties. Here, we clarified the cytotoxic potential of oleic acid, homovanillyl alc., and hydroxytyrosol on melanoma cells. Metabolic viability was determined 48 h post treatment of A375 and MNT1 cells. Metabolic gene expression was assessed by qRT-PCR and Mitogen-Activated Protein Kinase (MAPK) activation by Western blot. Hydroxytyrosol treatment (100 and 200μM) significantly reduced A375 cell viability (p = 0.0249; p < 0.0001) which, based on the expression anal. performed, is more compatible with a predominant glycolytic profile and c-Jun N-terminal kinase (JNK) activation. By contrast, hydroxytyrosol had no effect on MNT1 cell viability, which demonstrates an enhanced oxidative metabolism and extracellular signal-regulated kinase (ERK) activation. This compound triggered cell detoxification and the use of alternative energy sources in A375 cells, inhibiting JNK and ERK pathways. Despite oleic acid and homovanillyl alc. demonstrating no effect on melanoma cell viability, they influenced the MNT1 glycolytic rate and A375 detoxification mechanisms, resp. Both compounds suppressed ERK activation in MNT1 cells. The distinct cell responses to olive oil compounds depend on the metabolic and mol. mechanisms preferentially activated. Hydroxytyrosol may have a cytotoxic potential in melanoma cells with predominant glycolytic metabolism and JNK activation.

Bisdemethoxycurcumin (BDMC) has biol. activities, including anticancer effects in vitro; however, its anticancer effects in human glioblastoma (GBM) cells have not been examined yet. This study aimed to evaluate the tumor inhibitory effect and mol. mechanism of BDMC on human GBM 8401/luc2 cells in vitro and in vivo. In vitro studies have shown that BDMC significantly reduced cell viability and induced cell apoptosis in GBM 8401/luc2 cells. Furthermore, BDMC induced apoptosis via inhibited Bcl-2 (anti-apoptotic protein) and increased Bax (pro-apoptotic proteins) and cytochrome c release in GBM 8401/luc2 cells in vitro. Then, twelve BALB/c-nude mice were xenografted with human glioblastoma GBM 8401/luc2 cancer cells s.c., and the xenograft nude mice were treated without and with BDMC (30 and 60 mg/kg of BDMC treatment) every 3 days. GBM 8401/luc2 cell xenografts experiment showed that the growth of the tumors was significantly suppressed by BDMC administration at both doses based on the reduction of tumor size and weights BDMC did not change the body weight and the H&E histopathol. anal. of liver samples, indicating that BDMC did not induce systemic toxicity. Meanwhile, treatment with BDMC up-regulated the expressions of BAX and cleaved caspase-3, while it down-regulated the protein expressions of Bcl-2 and XIAP in the tumor tissues compared with the control group. This study has demonstrated that BDMC presents potent anticancer activity on the human glioblastoma GBM 8401/luc2 cell xenograft model by inducing apoptosis and inhibiting tumor cell proliferation and shows the potential for further development to the anti-GBM cancer drug.

Bisphosphonate inhibitors of squalene synthase protect cells against cholesterol-dependent cytolysins was written by Pospiech, Mateusz;Owens, Sian E.;Miller, David J.;Austin-Muttitt, Karl;Mullins, Jonathan G. L.;Cronin, James G.;Allemann, Rudolf K.;Sheldon, I. Martin. And the article was included in FASEB Journal in 2021.Formula: C3H9NO The following contents are mentioned in the article:

Certain species of pathogenic bacteria damage tissues by secreting cholesterol-dependent cytolysins, which form pores in the plasma membranes of animal cells. However, reducing cholesterol protects cells against these cytolysins. As the first committed step of cholesterol biosynthesis is catalyzed by squalene synthase, we explored whether inhibiting this enzyme protected cells against cholesterol-dependent cytolysins. We first synthesized 22 different nitrogen-containing bisphosphonate mols. that were designed to inhibit squalene synthase. Squalene synthase inhibition was quantified using a cell-free enzyme assay, and validated by computer modeling of bisphosphonate mols. binding to squalene synthase. The bisphosphonates were then screened for their ability to protect HeLa cells against the damage caused by the cholesterol-dependent cytolysin, pyolysin. The most effective bisphosphonate reduced pyolysin-induced leakage of lactate dehydrogenase into cell supernatants by >80%, and reduced pyolysin-induced cytolysis from >75% to <25%. In addition, this bisphosphonate reduced pyolysin-induced leakage of potassium from cells, limited changes in the cytoskeleton, prevented mitogen-activated protein kinases cell stress responses, and reduced cellular cholesterol. The bisphosphonate also protected cells against another cholesterol-dependent cytolysin, streptolysin O, and protected lung epithelial cells and primary dermal fibroblasts against cytolysis. Our findings imply that treatment with bisphosphonates that inhibit squalene synthase might help protect tissues against pathogenic bacteria that secrete cholesterol-dependent cytolysins.

Catalytic level identification of ZSM-5 on biomass pyrolysis and aromatic hydrocarbon formation was written by Chen, Wei-Hsin;Cheng, Ching-Lin;Lee, Kuan-Ting;Lam, Su Shiung;Ong, Hwai Chyuan;Ok, Yong Sik;Saeidi, Samrand;Sharma, Amit K.;Hsieh, Tzu-Hsien. And the article was included in Chemosphere in 2021.Synthetic Route of C9H12O3 The following contents are mentioned in the article:

Zeolite socony mobil-5 (ZSM-5) is a common catalyst used for biomass pyrolysis. Nevertheless, the quant. information on the catalytic behavior of ZSM-5 on biomass pyrolysis is absent so far. This study focuses on the catalytic pyrolysis phenomena and mechanisms of biomass wastes using ZSM-5 via thermogravimetric analyzer and pyrolysis-gas chromatog./mass spectrometry, with particular emphasis on catalytic level identification and aromatic hydrocarbons (AHs) formation. Two biomass wastes of sawdust and sorghum distillery residue (SDR) are investigated, while four biomass-to-catalyst ratios are considered. The anal. suggests that biomass waste pyrolysis processes can be divided into three zones, proceeding from a heat-transfer dominant zone (zone 1) to catalysis dominant zones (zones 2 and 3). The indicators of the intensity of difference (IOD), catalytic effective area, catalytic index (CI), and aromatic enhancement index are conducted to measure the catalytic effect of ZSM-5 on biomass waste pyrolysis and AHs formation. The maximum IOD occurs in zone 2, showing the highest intensity of the catalytic effect. The CI values of the two biomass wastes increase with increasing the biomass-to-catalyst ratio. However, there exists a threshold for sawdust pyrolysis, indicating a limit for the catalytic effect on sawdust. The higher the catalyst addition, the higher the AHs proportion in the vapor stream. When the biomass-to-catalyst ratio is 1/10, AHs formation is intensified significantly, especially for sawdust. Overall, the indexes conducted in the present study can provide useful measures to identify the catalytic pyrolysis dynamics and levels.

Extraction of curcumin from Curcuma longa using meglumine and pyroglutamic acid, respectively, as solubilizer and hydrotrope was written by Degot, Pierre;Funkner, Diana;Huber, Verena;Koeglmaier, Moritz;Touraud, Didier;Kunz, Werner. And the article was included in Journal of Molecular Liquids in 2021.Application of 33171-05-0 The following contents are mentioned in the article:

In preceding papers, it could be shown that mixtures of water, ethanol, and triacetin can significantly boost the extraction of curcuminoids out of Curcuma longa, compared to the usually applied water-ethanol mixtures To further improve it, additives can be beneficial. We show that meglumine and pyroglutamic acid are among the most promising of these additives. First, the influence of meglumine and pyroglutamic acid on the phase diagram of ternary mixtures consisting of water, ethanol and triacetin has been investigated: the addition of meglumine to the water phase only slightly increases the miscibility gap, whereas pyroglutamic acid increases it significantly in the oil-rich region. The solubility of curcumin could be significantly enhanced through the addition of meglumine. Extractions were successfully conducted extracting ∼18 mg of curcuminoids per g Curcuma longa by adding 15 wt% of meglumine to the amount of water in the extraction mixtures consisting of water, ethanol and triacetin, which is an increase of ∼ 20% compared to the best extraction mixture water/ethanol/triacetin from the previous study. A simple water/meglumine extraction was also investigated. Around 13 mg curcuminoids per g Curcuma longa could be extracted Bisdemethoxycurcumin contributes 3.46 mg to the total amount, which is a very good extraction yield (increase of 19% compared to the best extraction mixture from the previous study). The purity of the extract reached 87% just by extracting with water and meglumine. For comparison, the same purity was achieved using the ternary water/ethanol/triacetin system, but only after freeze drying of the rhizomes before extraction This study involved multiple reactions and reactants, such as Bisdemethoxycurcumin (cas: 33171-05-0Application of 33171-05-0).

Fluorescence Sensing of Formaldehyde and Acetaldehyde Based on Responsive Inverse Opal Photonic Crystals: A Multiple-Application Detection Platform was written by Lu, Xiaokang;Li, Ran;Han, Bo;Ma, Haojie;Hou, Xueyan;Kang, Yulong;Zhang, Yuqi;Wang, Ji-Jiang. And the article was included in ACS Applied Materials & Interfaces in 2021.Synthetic Route of C3H9NO The following contents are mentioned in the article:

Formaldehyde (FA) and acetaldehyde (AcH) used as common chems. in many fields are carcinogenic. The presently reported detection methods usually need expensive instruments, professional technicians, and time-consuming processes, and the detection sensitivity still needs further improvement. Herein, we report a highly effective fluorescence (FL) sensing film for FA and AcH based on naphthalimide derivative-infiltrated responsive SiO₂ inverse opal photonic crystals (PCs), establishing a practically multiple-application detection platform for FA and AcH in air, aquatic products, and living cells. Nucleophilic addition products between the amine group of the naphthalimide derivative and aldehydes emit strong FL at ~550 nm, realizing selective FL detection for FA and AcH. The emitted FL can be enhanced remarkably because of the slow photon effect of PCs, in which the FL wavelength is located at the stopband edge of PCs. A highly sensitive detection for FA and AcH with limits of detection of 10.6 and 7.3 nM, resp., is achieved, increasing 3 orders of magnitude compared with that in the solution system. Addnl., the interconnected three-dimensional microporous inverse opal structure endows the sensor with a rapid response within 1 min. Furthermore, the as-prepared PC sensor can be reused by simple washing in an acidic aqueous solution The sensing system can be used as a FL multi-detection platform for FA and AcH in air, aqueous solution, and living cells. This FL sensing approach based on small organic mol.-functionalized PCs is universally available to develop various sensors for target analytes by designing new functional organic compounds This study involved multiple reactions and reactants, such as 2-Methoxyethylamine (cas: 109-85-3Synthetic Route of C3H9NO).

Structural optimization using plant secondary metabolites as templates is one of the important approach to discover pesticide mols. with novel skeletons. Xanthatin, a natural sesquiterpene lactone isolated from the Xanthium plants (Family: Compositae), exhibits important biol. properties. In this work, a series of Michael-type amino derivatives were prepared from xanthatin and their structures were characterized by ¹H NMR, ¹³C NMR and HR-MS, and their antifungal activities against several phytopathogenic fungi were evaluated according to the spore germination method and mycelium growth rate method in vitro. The results illustrated that compounds I (IC₅₀ = 78.91μg/mL) and II (IC₅₀ = 64.51μg/mL) exhibited more promising inhibition activity against spores of F. solani than precursor xanthatin, three compounds exhibited remarkable antifungal effect on C. mandshurica with the average inhibition rates (AIRs) >90%, whereas the AIR of xanthatin was only 59.34%. Meanwhile, the preliminary structure-activity relationships suggested that the amino containing 2-methoxyethyl or 4-chlorophenylmethyl group appended in the C-13 position of xanthatin could yield potential compounds against fungal spores, and the exocyclic double bond of xanthatin is essential to maintain its mycelial growth inhibitory activity. Therefore, the aforementioned findings indicate that partial xanthatin amino-derivatives could be considered for further exploration as the potential lead structures toward development of the new environmentally friendly fungicidal candidates for sustainable crop protection.

Water Transport Polymers: Structure/Property Relationships of a Series of Phosphazene Polymers was written by Stone, Mark L.;Orme, Christopher J.;Peterson, Eric S.;Bauer, William F.;Stewart, Frederick F.;Harrup, Mason K.;Luther, Thomas A.;Klaehn, John R.;Wey, John E..

A study was undertaken to explore the water passing properties of a series of phosphazene polymers vs. the attached pendant group structure. Pendant groups containing different numbers of ethyleneoxy groups were synthetically attached to the backbone of phosphazene polymers. Phosphazene polymers facilitate these types of studies because, during their synthesis, the polymer backbone is formed first and then the desired pendant groups are attached through nucleophilic substitution. For these studies, four polymer series were synthesized and tested for their water passing properties. The polymers contained different amounts of ethyleneoxy units. Two different polymer families were synthesized and compared in this work. The critical difference in the two polymer series is that one contained pendant groups with aromatic rings, in addition to the oligioethyleneoxy moieties, while the other has no aromatic rings in its structure. Polymers with Ph group-containing pendant groups exhibited poor water permeability if they possessed fewer than six ethyleneoxy units. Polymers with more than six ethyleneoxy units inserted between the Ph ring (tail) and the polymeric backbone exhibited reasonable water permeability. Two addnl. series of polymers with mixed pendant groups were synthesized and the water passing properties of the phosphazenes varied in proportion to the hydrophilic to hydrophobic balance induced by each individual pendant group. A final study of polymers with shorter pendant groups demonstrated the effect of pendant group on water permeability. These studies suggest that the polyphosphazenes may be tailored for specific water passing applications. This study involved multiple reactions and reactants, such as 2-(2-(Hexyloxy)ethoxy)ethanol (cas: 112-59-4COA of Formula: C10H22O3).

Sequence-function relationship within water-soluble Peptoid Chelators for Cu²⁺ was written by Ghosh, Pritam;Rozenberg, Ido;Maayan, Galia. And the article was included in Journal of Inorganic Biochemistry in 2021.COA of Formula: C3H9NO The following contents are mentioned in the article:

Chelation of Cu2+ by synthetic mols. is an emerging therapeutic approach for treating several illnesses in human body such as Wilson disease, cancer and more. Among synthetic metal chelators, those based on peptoids – N-substituted glycine oligomers – are advantageous due to their structural similarity to peptides, ease of synthesis on solid support and versatile controlled sequences. Tuning peptoid sequences, via systematically changing at least one side chain, can facilitate and control their function. Along these lines, this work aims to explore the role of the non-coordinating side chain within peptoid chelators in order to understand the factors that control the selectivity of these chelators to Cu2+ in water medium. To this aim, a set of peptoid trimers having a pyridine group at the acetylated N-terminal, a 2,2-bipyridine group at the second position and a non-coordinating group at the C-terminus, where the latter is systematically varied between aromatic, aliphatic, chiral or non-chiral, were investigated as selective chelators for Cu2+. The effect of the position of the non-coordinating group on the selectivity of the peptoid to Cu2+ was also tested. Based on extensive spectroscopic data, we found that the choice of the non-coordinating group along with its position dramatically influences the selectivity of the peptoids to Cu2+. We showed that peptoids having bulky chiral groups at the C-terminus enable high selectivity to Cu2+. We further demonstrated the ability of one of the selective chelators to remove Cu2+ from the natural copper binding protein metallothionein in HEPES (4-(2-hydroxyethyl)-1-piperazineethanesulfonic acid) buffer medium.
