Stankovic, Ivana M.; Blagojevic Filipovic, Jelena P.; Zaric, Snezana D. published the artcile< Carbohydrate - Protein aromatic ring interactions beyond CH/π interactions: A Protein Data Bank survey and quantum chemical calculations>, Name: (2S,3R,4S,5S,6R)-6-(Hydroxymethyl)tetrahydro-2H-pyran-2,3,4,5-tetraol, the main research area is glucose carbohydrate protein aromatic ring interaction quantum chem method; Aromatic amino acids; CH/π interactions; Carbohydrates; Stacking interactions.

The geometries of the contacts between monosaccharides and aromatic rings of amino acids found in X-ray crystallog. structures, in the Protein Data Bank (PDB), were analyzed, while the energies of the interactions were calculated using quantum chem. method. We found 1913 sugar/aromatic ring contacts, 1054 of them (55%) with CH/π interactions and 859 of them (45%) without CH/π interactions. We showed that only the carbohydrate/aromatic contacts with CH/π interactions are preferentially parallel and enable sliding in the plane parallel to aromatic ring. The calculated interaction energies in systems with CH/π interactions are in the range from -1.7 kcal/mol to -6.8 kcal/mol, while in the systems without CH/π interactions are in the range -0.2 to -3.2 kcal/mol. Hence, the binding that does not include CH/π interactions, can also be important for aromatic amino acid and carbohydrate binding processes, since some of these interactions can be as strong as the CH/π interactions. At the same time, these interactions can be weak enough to enable releasing of small carbohydrate fragments after the enzymic reaction. The anal. of the protein-substrate patterns showed that every second or third carbohydrate unit in long substrates stacks with protein aromatic amino acids.

Hewitt, Kirsten A.; Xie, Pei-Pei; Thane, Taylor A.; Hirbawi, Nadia; Zhang, Shuo-Qing; Matus, Alissa C.; Lucas, Erika L.; Hong, Xin; Jarvo, Elizabeth R. published the artcile< Nickel-Catalyzed Domino Cross-Electrophile Coupling Dicarbofunctionalization Reaction To Afford Vinylcyclopropanes>, SDS of cas: 627-27-0, the main research area is vinylcyclopropane enantioselective diastereoselective preparation DFT; alkynyl tosylpiperidine domino cross electrophile coupling dicarbofunctionalization nickel catalyst.

A nickel-catalyzed domino reaction was established that harnesses sulfonamide, alkyl chloride, and alkyne functionalities in a multistep sequence to afford vinylcyclopropanes I [R = Me, n-hexyl, Ph, etc.] bearing tetrasubstituted olefins. The starting materials were prepared by iron-promoted aza-Prins reactions of ynals. This method provided rapid synthetic access to valuable building blocks with applications in medicinal chem. Exptl. and computational results supported the initiation of the catalytic cycle by the oxidative addition of propargylic sulfonamide, and a key ambiphilic allenylnickel intermediate leads to a bifurcated reaction pathway that generates olefin isomers.

Gu, Jinyan; Zhang, Haihui; Wen, Chaoting; Zhang, Jixian; He, Yuanqing; Ma, Haile; Duan, Yuqing published the artcile< Purification, characterization, antioxidant and immunological activity of polysaccharide from Sagittaria sagittifolia L.>, Related Products of 3458-28-4, the main research area is Sagittaria polysaccharide purification antioxidant immunol; Antioxidant; Immunomodulatory; Sagittaria sagittifolia L. polysaccharide.

As a healthy food and traditional Chinese medicine, sagittaria sagittifolia L. has been used for a long history. Nevertheless, reports on the bioactivity and chem. characterization of S. sagittifolia L. polysaccharides are still very rare. In this paper, ultrasound-assisted method (UAE) was used to extract S. sagittifolia L. polysaccharides, after alc. precipitation and column chromatog. isolation, the structural characteristics, antioxidant and immunol. activities of the purified polysaccharide (SPU60-W) were preliminarily investigated. The results indicated SPU60-W (16.62 kDa) was a pyranoid polysaccharide containing α-glycosidic bond composed of mannose, xylose, and glucose with a molar ratio of 2.69:2.04:95.27. It consisted of slender wormlike strands, which may involve some degree of aggregation of helixes, as well as a small proportion of irregular spherical structures. Furthermore, antioxidant activity anal. showed that SPU60-W possess excellent hydroxyl and ABTS radical scavenging activity comparable to vitamin C (Vc), and moderate DPPH radical scavenging activity. Immunity tests suggested that SPU60-W significantly promoted the proliferation, phagocytosis and NO production of mouse macrophage RAW264.7. According to this study, SPU60-W might be utilized as a potent antioxidant and immunomodulator in food and medicinal industry.

In this work, the synthesis of a new polysiloxane, poly {dimethylsiloxane-co-[4-(2,3-difluoro-4-hydroxyphenoxy) butyl] methylsiloxane} (dubbed PMFOS), is presented. This polymer exhibits high hydrogen bond acidity and was designed to be used as a sensor layer in gas sensors. The description of the synthetic route of the PMFOS has been divided into two main stages: the synthesis of the functional substituent 4-(but-3-en-1-yloxy)-2,3-difluorophenol, and the post-polymerization functionalization of the polysiloxane chain (methylhydrosiloxane-dimethylsiloxane copolymer) via hydrosilylation. The synthesized material was subjected to instrumental anal., which confirmed its structure. The performed thermal anal. made it possible to determine some properties important for the sensor application, such as glass transition temperature and decomposition temperature The results showed that PMFOS meets the requirements for materials intended for use in gas sensors based on acoustoelec. transducers.

Schaarschmidt, Stephanie; Glaubitz, Ulrike; Erban, Alexander; Kopka, Joachim; Zuther, Ellen published the artcile< Differentiation of the High Night Temperature Response in Leaf Segments of Rice Cultivars with Contrasting Tolerance>, SDS of cas: 87-73-0, the main research area is Oryza cultivar leaf segment high night temperature; RNA-Seq; high night temperature; leaf segments; metabolomics; rice cultivars; sheath.

High night temperatures (HNT) affect rice yield in the field and induce chlorosis symptoms in leaves in controlled chamber experiments However, little is known about mol. changes in leaf segments under these conditions. Transcript and metabolite profiling were performed for leaf segments of six rice cultivars with different HNT sensitivity. The metabolite profile of the sheath revealed a lower metabolite abundance compared to segments of the leaf blade. Furthermore, pre-adaptation to stress under control conditions was detected in the sheath, whereas this segment was only slightly affected by HNT. No unique significant transcriptomic changes were observed in the leaf base, including the basal growth zone at HNT conditions. Instead, selected metabolites showed correlations with HNT sensitivity in the base. The middle part and the tip were most highly affected by HNT in sensitive cultivars on the transcriptomic level with higher expression of jasmonic acid signaling related genes, genes encoding enzymes involved in flavonoid metabolism and a gene encoding galactinol synthase. In addition, gene expression of expansins known to improve stress tolerance increased in tolerant and sensitive cultivars. The investigation of the different leaf segments indicated highly segment specific responses to HNT. Mol. key players for HNT sensitivity were identified.

Rana, Rohit; Shreya; Upadhyay, Rahul; Maurya, Sushil K. published the artcile< Synthesis of Macrocyclic Lactones and Dilactones Using Olive Oil>, Recommanded Product: But-3-en-1-ol, the main research area is ester olive oil Grubbs second generation macrocyclization catalyst; lactone preparation; dilactone preparation.

Macrocyclic lactones have redolent characteristics of muscones that originate from the rectal musk organs of the musk deer. These lactones are the primary raw material in the flavor and fragrance industry and are also found within the cyclic frameworks of various bioactive mols. Due to great demand, many efforts have been made for their synthesis; however, strategies generating a large number of macrocyclic analogs from renewable resources have not been fully realized and are urgently required. Here, we outline a sustainable, straightforward, and eco-friendly approach to synthesize high-valued macrocyclic lactones utilizing olive oil under greener reaction conditions. The outlined method allows us to turn biomass into valuable 12- to 29-membered lactones and dilactones.

Alonso-Gil, Santiago published the artcile< MonteCarbo : A software to generate and dock multifunctionalized ring molecules>, SDS of cas: 492-62-6, the main research area is software multifunctionalized ring active site glycosidase; Monte Carlo; carbohydrates; conformations; docking; drug design.

MonteCarbo is an open-source software to construct simple 5-, 6-, and 7-membered ring multifunctionalized monosaccharides and nucleobases and dock them into the active site of carbohydrate-active enzymes. The core bash script executes simple orders to generate the Z-matrix of the neutral mol. of interest. After that, a Fortran90 code based on a pseudo-random number generator (Monte Carlo method) is executed to assign dihedral angles to the different rotamers present in the structure (ring and rotating functional groups). The program also has a generalized internal coordinates (GIC) implementation of the Cremer and Pople puckering coordinates ring. Once the structures are generated and optimized, a second code is ready to execute in serial the docking of multiple conformers in the active site of a wide family of enzymes.
