Agatonovic-Kustrin, S.; Kustrin, E.; Gegechkori, V.; Morton, D. W. published the artcile< Anxiolytic Terpenoids and Aromatherapy for Anxiety and Depression>, Synthetic Route of 78-70-6, the main research area is review anxiolytic terpenoid aromatherapy anxiety depression; Anxiety; Aromatherapy; Depression; Essential oil; Terpenoids.

A review. In our society, anxiety and depression are serious health issues that affect a large proportion of the population. Unfortunately, drug therapies are not always effective and can lead to drug abuse, delay of therapeutic effect, dependence, and tolerance. Traditionally, aromatherapy has also been used for anxiety relief and mood improvement. The use of essential oils, in relieving anxiety and depression, does not have the disadvantages associated with currently used drug therapies. In-vivo studies on animal models have verified the anxiolytic effects of these essential oils and the interactions of their major components with central nervous system receptors. Therefore, it seems reasonable to argue that the modulation of glutamate and GABA neurotransmitter systems are likely to be the critical mechanisms responsible for the sedative, anxiolytic, and anticonvulsant proprieties of linalool and essential oils containing linalool in significant proportions. Popular anxiolytic essential oils are generally rich in terpenoid alcs. like linalool, geraniol and citronellol, and the monoterpene limonene (or citral). Therefore, other essential oils or formulations that contain these terpenoids as major components may serve as important aromatherapeutics for relief of anxiety.

Zhang, Xinyu; Li, Linxuan; Zanoni, Giuseppe; Han, Xinyue; Bi, Xihe published the artcile< Direct gem-Difluoroalkenylation of X-H Bonds with Trifluoromethyl Ketone N-Triftosylhydrazones for Synthesis of Tetrasubstituted Heteroatomic gem-Difluoroalkenes>, Quality Control of 627-27-0, the main research area is heteroatomic gem difluoroalkene preparation DFT; trifluoromethyl ketone triftosylhydrazone amine difluoroalkenylation silver catalyst; alc trifluoromethyl ketone triftosylhydrazone difluoroalkenylation silver catalyst; carbene; difluoroalkene; difluoroalkenylation; rhodium catalysis; silver catalysis.

Here, the first direct X-H bond gem-difluoroalkenylation of amines, e.g., N-methylaniline and alcs., e.g., methanol with trifluoromethyl ketone N-triftosylhydrazones, e.g., benzenesulfonic acid, 2-(trifluoromethyl)-, 2-(2,2,2-trifluoro-1-phenylethylidene)hydrazide under silver (for (hetero)aryl hydrazones) or rhodium (for alkyl hydrazones) was reported, thereby providing a most powerful method for the synthesis of tetrasubstituted heteroat. gem-difluoroalkenes, e.g., (2,2-difluoro-1-phenyl-vinyl)-methyl-phenyl-amine/1,1-difluoro-2-methoxy-2-phenylethene. This method features a broad substrate scope, high product yield, excellent functional group tolerance, and operational simplicity (open air conditions). Moreover, the site-specific replacement of the carbonyl group with a gem-difluorovinyl ether bioisostere in drug Trimebutine and the post-modification of bioactive mols. demonstrates potential use in medicinal research. Finally, the reaction mechanism was investigated by combining experiments and DFT calculations, and disclosed that the key step of HF elimination occurred via five-membered ring transition state, and the difference in the electrophilicity of Ag- and Rh-carbenes as well as the multiple intermol. interactions rendered the effectiveness of Rh catalyst selectively for alkyl hydrazones.

Angulo, Beatriz; Fraile, Jose M.; Gil, Laura; Herrerias, Clara I. published the artcile< Comparison of Chemical and Enzymatic Methods for the Transesterification of Waste Fish Oil Fatty Ethyl Esters with Different Alcohols>, Category: alcohols-buliding-blocks, the main research area is enzyme transesterification waste fish oil fatty ethyl ester alc.

Fatty acid esters of 2-ethyl-1-hexanol (EH), 2-hexyl-1-decanol (HD), and isopropanol have been obtained from a mixture of Et esters obtained as a fish oil byproduct. Homogeneous base catalysis with alk. hydroxides and alkoxides has been compared with the use of two com. available immobilized lipases. The enzymic methodol. is more efficient in the case of the largest alc. (HD) mainly because of the high stability of the immobilized enzymes upon recovery and reuse. In contrast, the use of a base as a catalyst is highly favorable in the case of isopropanol because of the rather poor activity of the lipases and the low price of the bases. With EH, the activity of lipases is good but the recoverability is not as efficient; hence, basic catalysts are again the most attractive alternative. The mixtures of esters obtained may be useful as hydraulic liquids given their viscosity values.

Qu, Lisha; Xiu, Xiang; Sun, Guoyun; Zhang, Chenyang; Yang, Haiquan; Liu, Yanfeng; Li, Jianghua; Du, Guocheng; Lv, Xueqin; Liu, Long published the artcile< Engineered yeast for efficient de novo synthesis of 7-dehydrocholesterol>, Quality Control of 434-16-2, the main research area is 7-dehydrocholesterol; CRISPRi system; TY1 transposon; metabolic engineering; metabolic network model.

The synthesis of vitamin D3 precursor 7-dehydrocholesterol (7-DHC) by microbial fermentation has much attracted attention owing to its advantages of environmental protection. In this study, Saccharomyces cerevisiae was engineered for a de novo biosynthesis of 7-DHC. First, seven essential genes (six endogenous genes and one heterologous gene) were overexpressed, and the ROX1 gene (heme-dependent repressor of hypoxic genes) was knocked out. The resulting strain produced 82.6 mg/L 7-DHC from glucose. Then, we predicted five gene knockout targets for 7-DHC overproduction by the reconstruction of genome-scale metabolic model. GDH1 gene knockout increased the 7-DHC titer from 82.6 to 101.5 mg/L, and the specific growth rate of the ΔGDH1 mutant was also increased by 28%. Next, Ty1 transposon in S. cerevisiae was applied to increase the copies of the ERG1 gene and DHCR24 gene, resulting in a 120% increase in 7-DHC titer to 223.3 mg/L. Besides, to optimize the metabolic flux distribution, Clustered Regularly Interspaced Short Palindromic Repeats interference (CRISPRi) system was used to dynamically inhibit the competitive pathway, and the best binding site of ERG6 (delta (24)-sterol C-methyltransferase) promoter was screened out. The OD600 value of ERG6 regulated cells increased by 43% than knocking out ERG6 directly, and 7-DHC titer increased to 365.5 mg/L in a shake flask. Finally, the 7-DHC titer reached 1328 mg/L in 3-L bioreactor and the specific titer of 7-DHC reached up to 114.7 mg/g dry cell weight). Overall, this study constructed a yeast chassis for the highly efficient production of 7-DHC by systems metabolic engineering.

Bladder cancer is one of the most malignant tumors closely associated with macrophage immune dysfunction. The Chinese medicine polyporus has shown excellent efficacy in treating bladder cancer, with minimal side effects. However, its material basis and mechanism of action remain unclear. A new water-soluble polysaccharide (HPP) with strong immunomodulatory activity was isolated from the fungus Polyporus umbellatus (Pers.) Fries. HPP had an average mol. weight of 6.88 kDa and was composed mainly of an <-(1→ 4)-linked D-galactan backbone. The immunomodulatory activity of HPP was determined in vitro, and the results revealed that it could obviously increase the secretion of immune factors by IFN-γ-stimulated macrophages, including nitric oxide (NO), interleukin-6 (IL-6), interleukin-1β (IL-1β), RANTES and interleukin-23 (IL-23), and the expression of the cell membrane mol. CD80. In addition, HPP was recognized by Toll-like receptor 2 (TLR2) and activated the signaling pathways of NF-κB and NLRP3 in a bladder cancer microenvironment model, indicating that HPP could enhance host immune system function. These findings demonstrated that HPP may be a potential immune modulator in the treatment of immunol. diseases or bladder cancer therapy.

Kajiki, Takahito; Komba, Shiro; Iwaura, Rika published the artcile< Supramolecular Organogelation Directed by Weak Noncovalent Interactions in Palmitoylated 1,5-Anhydro-D-Glucitol Derivatives>, COA of Formula: C6H12O6, the main research area is palmitoylated anhydro glucitol supramol organogelation noncovalent interaction; carbohydrates; gelators; hydrogen bonding; nanofibers; self-assembly.

We synthesized a series of novel alicyclic compounds by modifying 1,5-anhydro-D-glucitol with two to four palmitoyl chains, and we explored their self-assembly and gelation behaviors in paraffin. The obtained organogels were studied by field emission SEM, at. force microscopy, variable-temperature Fourier transform IR spectroscopy, X-ray diffraction anal., polarized optical microscopy, and transmission spectroscopy. While all the palmitoylated derivatives spontaneously formed fibrous networks and gelated the paraffin, an acetylated derivative of 1,5-anhydro-D-glucitol did not gelatinize the solvent, thus indicating the importance of aliphatic chains for gelation. Interestingly, α- and β- D-glucopyranose with five palmitoyl chains neither gelatinized the solvent nor formed fibrous networks, thus suggesting that the absence of C-1 substitution in 1,5-anhydro-D-glucitol is important for gelation. Fourier transform IR spectroscopy suggested that the formation of weak hydrogen bonds between the carbonyl groups and the C-H groups was the driving force for formation of the supramol. fibers and for gelation of the solvent.
