Acascade synthesis protocol for glycosides of 1,4-butanediol monomesylate, as anticancer drug candidates, is proposed. All obtained compounds are characterized by FT-IR, 1H and 13C NMR spectroscopy technique after separation by column chromatog. Cytotoxicity of the obtained glucosides and galactosides of 1,4-butanediol monomesylate on K562 human erythroleukemia cell line and normal peripheral blood mononuclear cells (PBMCs) is also investigated. Compared to the commerical anticancer drugs such as busulfan and doxorubicin, these compounds indicate promising results against the test cells. It is suggested that these new anticancer agents can be a potential replacement for the current drugs since they have relatively convenient synthetic procedure and higher effectiveness.

Santiago, Marina; Sachdev, Shivani; Arnold, Jonathon C.; McGregor, Iain S.; Connor, Mark published the artcile< Absence of entourage: terpenoids commonly found in Cannabis sativa do not modulate the functional activity of Δ9-THC at human CB1 and CB2 receptors>, SDS of cas: 78-70-6, the main research area is Cannabis terpenoids tetrahydrocannabinol CB1 CB2 receptor; THC; cannabinoid receptor; entourage effect; phytocannabinoid; signaling; terpenoid.

We examined six common terpenoids alone, and in combination with cannabinoid receptor agonists, on CB1 and CB2 signaling in vitro. Potassium channel activity in AtT20 FlpIn cells transfected with human CB1 or CB2 receptors was measured in real time using FLIPR membrane potential dye in a FlexStation 3 plate reader. Terpenoids were tested individually and in combination for periods up to 30 min. Endogenous somatostatin receptors served as a control for direct effects of drugs on potassium channels. Alpha-Pinene, β-pinene, β-caryophyllene, linalool, limonene and β-myrcene did not change membrane potential in AtT20 cells expressing CB1 or CB2, or affect the response to a maximally effective concentration of the synthetic cannabinoid CP55,940. The presence of individual or combination of terpenoids did not affect the hyperpolarization produced by Δ9-THC. To investigate possible effect on desensitization of CB1 responses, all six terpenoids were added together with Δ9-THC and signaling measured continuously over 30 min. Terpenoids did not affect desensitization, after 30 min control hyperpolarization recovered by 63% -6% in the presence of terpenoids recovery was 61% -5%. None of the six of the most common terpenoids in Cannabis directly activated CB1 or CB2, or modulated the signaling of phytocannabinoid agonist Δ9-THC.

Wang, Wenliang; Jiang, Sangni; Li, Shengran; Yan, XinXin; Liu, Sanrong; Mao, Xiaobo; Yu, Xifei published the artcile< Functional Choline Phosphate Lipids for Enhanced Drug Delivery in Cancer Therapy>, SDS of cas: 627-27-0, the main research area is choline phosphate lipid drug delivery anticancer agent biocompatibility.

Liposome formulations by zwitterionic lipids (e.g., phosphatidyl choline (PC)) have been widely applied in the clin. translation of nanomedicines. However, poor bioorthogonality in the PC lipid backbone and limited cellular uptake potency significantly impede the development of a therapeutic strategy. Herein, we synthesized a novel bioorthogonal zwitterionic lipid named choline phosphate (CP), with reversed PC charge orientation via a phospholane derivative ring-opening reaction. CP lipids can assemble into liposomes with excellent biocompatibility and stable phys. and chem. properties similar to PC liposomes. Due to supramol. ionic pair interactions with the cell membrane, doxorubicin (Dox)-loaded CP liposomes (CP-Dox) were preferentially taken up and accumulated in cells compared to PC-Dox, which significantly enhanced the cytotoxicity in cancer cells and inhibited tumor growth. Furthermore, we determined the bioorthogonality of the CP lipids by conjugating folate in situ using a “”click”” reaction, which showed specificity in targeting treatment for breast cancer. Our studies provide a new proof of concept that functional liposomes can be designed at the mol. level. We also expect that CP lipids may have potential in other applications, including biosensors, antifouling coatings, cell membrane mimetic engineering, and artificial cells.

Bioelectronic devices that convert biochem. signals to electronic readout enable biosensing with high spatiotemporal resolution These technologies have been primarily applied in biomedicine while in plants sensing is mainly based on invasive methods that require tissue sampling, hindering in-vivo detection and having poor spatiotemporal resolution Here, we developed enzymic biosensors based on organic electrochem. transistors (OECTs) for in-vivo and real-time monitoring of sugar fluctuations in the vascular tissue of trees. The glucose and sucrose OECT-biosensors were implanted into the vascular tissue of trees and were operated through a low-cost portable unit for 48h. Our work consists a proof-of-concept study where implantable OECT-biosensors not only allow real-time monitoring of metabolites in plants but also reveal new insights into diurnal sugar homeostasis. We anticipate that this work will contribute to establishing bioelectronic technologies as powerful minimally invasive tools in plant science, agriculture and forestry.

Li, Xingru; Guo, Rui; Zhao, Yaxuan; Liu, Danping; Chen, Jing; Miao, Ningning; Gao, Shujuan; Guo, Jixun; Zhang, Tao; Shi, Lianxuan published the artcile< Wild soybean resists the stress of low phosphorus by increasing nutrient reuse between the young and old leaves>, Product Details of C6H10O8, the main research area is Glycine leaf age nutrient phosphorus deficiency metabolomics.

Screening and identification of plant resources with high quality and multi resistance is important for crop breeding. In this study, ion content was determined by ion chromatog. and at. absorption spectrophotometer, and gas chromatog.-mass spectrometry (GC-MS)-based metabolomic anal. was carried out. Then metabolic pathways were constructed using the Kyoto Encyclopedia of Genes and Genomes and the MetaboAnalyst website to compare the changes and differences of young and old leaves of two wild soybean lines with different stress tolerance under low-phosphorus (LP) stress. The aim was to reveal the mechanism of wild soybean resistance to LP stress from insights concerning nutrient accumulation and mobilization. The results showed that in LP-tolerant wild soybean, Ca2+ accumulated and TCA, amino acid and organic acid metabolisms were enhanced in young and old leaves; disaccharide and trisaccharide metabolism was enhanced and phosphohexose metabolism was inhibited in old leaves; Mg2+, disaccharide and trisaccharide contents increased in young leaves, while inorganic P was relatively stable. Our experiment highlighted that LP-tolerant wild soybean adapted to LP stress by enhancing energy and material metabolisms and maintaining the growth and development of young leaves at the expense of old leaves, which is of great significance for the development and utilization of germplasm resources and the breeding of LP-tolerant soybean.

Arora, Vinay; Narjinari, Himani; Kumar, Akshai published the artcile< Pincer-Nickel Catalyzed Selective Guerbet-Type Reactions>, Application of C8H9FO, the main research area is pincer nickel bis imino pyridine preparation crystal mol structure; Guerbet type reaction pincer iminopyridine nickel catalyzed; alkylation phenyl ethanol benzyl alc nickel iminopyridine catalyzed.

Authors report here the synthesis and characterization of a series of NNN pincer-nickel complexes of the type (R2NNN)NiCl2(CH3CN) (R = iPr, tBu, Cy, Ph, and p-F-C6H4) based on bis(imino)pyridine ligands. In solution, these complexes are equilibrium mixtures containing one and two pincer ligands, resp. While the crystal structure of the former was reported by us recently for R = iPr, they report the crystal structure of the latter in this study for R = p-F-C6H4. The considered NNN pincer-Ni complexes have been successfully employed to accomplish the catalytic β-alkylation of several secondary alcs. with a variety of benzyl alcs. at 140° with high yields and unprecedented turnovers. A maximum of 92% yield of the β-alkylated product at 18 400 TON was obtained in the reaction of benzyl alc. with 1-(4-(trifluoromethyl)phenyl)ethane-1-ol in the presence of 0.005 mol % of (Ph2NNN)NiCl2(CH3CN) and 5 mol % of NaOtBu at 140° after 24 h. The reaction exhibits zero-order dependence of rate on catalyst concentration and first-order dependence on the concentration of base, benzyl alc., and 1-Ph ethanol which points to the base-mediated aldol condensation as the rate-determining step. Most of the intermediates involved in catalysis have been identified by HRMS. To the best of their knowledge, this is the first report on a pincer-Ni catalyzed β-alkylation of alcs. and, hitherto, such unprecedented turnovers have not been reported with a homogeneous mol. nickel-based catalyst.

Denavit, Vincent; Laine, Danny; Bouzriba, Chahrazed; Shanina, Elena; Gillon, Emilie; Fortin, Sebastien; Rademacher, Christoph; Imberty, Anne; Giguere, Denis published the artcile< Stereoselective Synthesis of Fluorinated Galactopyranosides as Potential Molecular Probes for Galactophilic Proteins: Assessment of Monofluorogalactoside-LecA Interactions>, Electric Literature of 4064-06-6, the main research area is stereoselective galactopyranoside galactophilic protein monofluorogalactoside LecA interaction; crystal structure; LecA; NMR spectroscopy; TROSY NMR; carbohydrates; fluorinated glycoside.

The replacement of hydroxyl groups by fluorine atoms on hexopyranoside scaffolds may allow access to invaluable tools for studying various biochem. processes. As part of ongoing activities toward the preparation of fluorinated carbohydrates, a systematic investigation involving the synthesis and biol. evaluation of a series of mono- and polyfluorinated galactopyranosides is described. Various monofluorogalactopyranosides, a trifluorinated, and a tetrafluorinated galactopyranoside have been prepared using a Chiron approach. Given the scarcity of these compounds in the literature, in addition to their synthesis, their biol. profiles were evaluated. Firstly, the fluorinated compounds were investigated as antiproliferative agents using normal human and mouse cells in comparison with cancerous cells. Most of the fluorinated compounds showed no antiproliferative activity. Secondly, these carbohydrate probes were used as potential inhibitors of galactophilic lectins. The first transverse relaxation-optimized spectroscopy (TROSY) NMR experiments were performed on these interactions, examining chem. shift perturbations of the backbone resonances of LecA, a virulence factor from Pseudomonas aeruginosa. Moreover, taking advantage of the fluorine atom, the 19F NMR resonances of the monofluorogalactopyranosides were directly monitored in the presence and absence of LecA to assess ligand binding. Lastly, these results were corroborated with the binding potencies of the monofluorinated galactopyranoside derivatives by isothermal titration calorimetry experiments Analogs with fluorine atoms at C-3 and C-4 showed weaker affinities with LecA as compared to those with the fluorine atom at C-2 or C-6. This research has focused on the chem. synthesis of “”drug-like”” low-mol.-weight inhibitors that circumvent drawbacks typically associated with natural oligosaccharides.

A new radical-mediated alkoxypolyhaloalkylation of styrenes RCH=C(R1)R2 (R = H, Me; R1 = 4-methoxyphenyl, 3-methylthiophen-2-yl, 6-bromo-2H-1,3-benzodioxol-5-yl, etc.; R2 = H, Me, Ph) with polychloroalkanes HCR3R4R5 (R3 = H, Cl, Br; R4 = H, Cl, Br; R5 = Cl, Br, bromomethyl, chloromethyl, dichloromethyl) and alcs. R6OH (R6 = Me, 2,2-dimethylpropyl, 4-phenylbutyl, adamantan-2-yl, etc.) and aniline is provided for the facile synthesis of complex polyhaloalkanes R1R2C(OR6)C(R)CR3R4R5 and N-(3,3,3-trichloro-1-(4-methoxyphenyl)propyl)aniline. The 4-methoxybenzenediazonium tetrafluoroborate is a good radical initiator for this transformation. This protocol is well applied to the late-stage functionalization of complex mols., including vitamin E, estrone and cholesterol derivs e.g., I.

Froiio, Francesca; Ginot, Lorianne; Paolino, Donatella; Lebaz, Noureddine; Bentaher, Abderrazzak; Fessi, Hatem; Elaissari, Abdelhamid published the artcile< Essential oils-loaded polymer particles: preparation, characterization and antimicrobial property>, Application In Synthesis of 78-70-6, the main research area is essential oil polymer particle antimicrobial; Escherichia coli; Eudragit RS100; antimicrobials; bergamot essential oil; nanoparticles; nanoprecipitation; sweet orange essential oil.

In the last few years, essential oils (EOs) derived from plants have aroused great interest due to their well-known antimicrobial activity. Unfortunately, they present several limitations in their use, such as photosensitivity, temperature sensitivity, high volatility, and poor water solubility The encapsulation technique represents a good solution to these problems and ensures protection of the functional properties of essential oils. In this work, bergamot essential oil (BEO) and sweet orange essential oil (OEO) loaded-Eudragit RS 100 (EuRS100) nanoparticles (NPs) were prepared by using the nanopptn. technique. We obtained nanoparticles characterized by a mean diameter of 57 to 208 nm and a pos. surface charge (39 to 74 mV). The antibacterial activity of the obtained systems against Escherichia coli was in vitro investigated. We demonstrated that both orange and bergamot essential oils were successfully encapsulated and our nanoparticles have good antibacterial activity. Finally, in order to evaluate the potential applicability of OEONps to prolong fresh orange juice shelf-life, survival of E. coli during a storage period of one week at 25°C was investigated: Orange essential oil-loaded nanoparticles (OEONPs) have been able to prolong the orange juice shelf life.

Heng, Ya Gao; Wen, Li Peng; Pan, Pan Meng; Xue, Feng Feng; Jian, Qiang Li; Hui, Qiong Wu; Chang, Sheng Yan; Yang, Yang Xiong; Luo, Feng published the artcile< Lanthanide separation using size-selective crystallization of Ln-MOFs>, Formula: C14H8N2Na2O6, the main research area is size selective crystallization separation lanthanide olsalazine MOF; crystal structure lanthanide olsalazine MOF preparation.

Herein, the authors report an elaborate method, size-selective crystallization of Ln-MOFs, to isolate lanthanide (Ln) ions. Herein, 13 lanthanide ions, except for the radioactive Pm(III) ion and ytterbium, were separated by four types of Ln-MOFs: type I [La-Pr, Ln2(OLZ)(H2OLZ)(DMF)(H2O)2·2H2O], type II [Nd-Eu, Ln(OLZ)0.5(H2OLZ)0.5(DMF)(μ2-DMF)0.5], type III [Gd-Ho, Ln(OLZ)0.5(H2OLZ)0.5(DMF)(H2O)·H2O], and type IV [Er-Lu, Ln2(OLZ)(H2OLZ)(H2O)4 where OLZ = olsalazine]. Further systemic investigation also suggested the highly selective separation of lanthanide ions by this method.
