The article was 《Tethering Carbohydrates to the Vinyliminium Ligand of Antiproliferative Organometallic Diiron Complexes》. The article mentions the following:

Four propargyl O-glycosides derivatized with mannose, glucose, and fructose moieties were synthesized and then incorporated within a diiron structure as part of a vinyliminium ligand. Hence, six glycoconjugated diiron complexes, [2-5]CF3SO3 (see Scheme 1) and the nonglycosylated analogs [6a-b]CF3SO3, were obtained in high yields and unambiguously characterized by elemental anal., mass spectrometry, and IR and multinuclear NMR spectroscopies. All compounds exhibited a significant stability in DMSO-d6/D2O solution, with 63-89% of the complexes unaltered after 72 h at 37° and also in the cell culture medium. The cytotoxicity of [2-6]CF3SO3, as well as that of previously reported 7 and 8, was assessed on CT26 (mouse colon carcinoma), U87 (human glioblastoma), MCF-7 (human breast adenocarcinoma), and RPE-1 (human normal retina pigmented epithelium) cell lines. In general, the IC50 values correlate with the hydrophobicity of the compounds (measured as octanol-H2O partition coefficients) and do not show an appreciable level of selectivity against cancer cells with respect to the nontumor ones.

Formula: C24H34O2On October 25, 2021 ,《Density Functional Theory-Inspired Design of Ir/P,S-Catalysts for Asymmetric Hydrogenation of Olefins》 was published in Organometallics. The article was written by Faiges, Jorge; Borras, Carlota; Pastor, Isidro M.; Pamies, Oscar; Besora, Maria; Dieguez, Montserrat. The article contains the following contents:

In silico-based optimization of Ir/P,S-catalysts for the asym. hydrogenation of unfunctionalized olefins using (E)-1-(but-2-en-2-yl)-4-methoxybenzene as a benchmark olefin has been carried out. DFT calculations revealed that the thioether group has a major role in directing the olefin coordination. This, together with the configuration of the biphenyl phosphite group, has an impact in maximizing the energy gap between the most stable transition states leading to opposite enantiomers. As a result, the optimized catalyst proved to be efficient in the hydrogenation of a range of alkenes with the same substitution pattern and olefin geometry as the benchmark olefin, regardless of the presence of functional groups with different coordination abilities (ee values up to 97%). Appealingly, further modifications at the thioether groups and at the biaryl phosphite moiety allowed the highly enantioselective hydrogenation of olefins with different substitution patterns (e.g., α,β-unsaturated lactones and lactams, 1,1′-disubstituted enol phosphinates, and cyclic β-enamides; ee values up to >99%).(R)-3,3′-Di-tert-butyl-5,5′,6,6′-tetramethylbiphenyl-2,2′-diol(cas: 329735-68-4Formula: C24H34O2) was used in this study.

(R)-3,3′-Di-tert-butyl-5,5′,6,6′-tetramethylbiphenyl-2,2′-diol(cas: 329735-68-4) belongs to phenols. Phenols are more acidic than typical alcohols. The acidity of the hydroxyl group in phenols is commonly intermediate between that of aliphatic alcohols and carboxylic acids (their pKa is usually between 10 and 12).Formula: C24H34O2

Room temperature Pd(0)/Ad3P-catalyzed cross-coupling reactions of aryl chlorides with bis(pinacolato)diboron are described. The Pd(0)/Ad3P catalyst, generated from Ad3P-coordinated acetanilide-based palladacycle complex, proved to be an efficient catalyst system for the Miyaura borylation reactions of a variety of aryl chlorides with bis(pinacolato)diboron.

Synthetic Route of C6H12O6On October 31, 2019 ,《Initial pyrolysis mechanism of cellulose revealed by in-situ DRIFT analysis and theoretical calculation》 appeared in Combustion and Flame. The author of the article were Dai, Gongxin; Wang, Kaige; Wang, Guanyu; Wang, Shurong. The article conveys some information:

Cellulose is one of the major components of biomass. The study on its pyrolysis process will be beneficial to the in-depth understanding of biomass pyrolysis mechanism. In this work, in-situ diffuse reflectance IR Fourier transform spectroscopy (in-situ DRIFT) combined with two-dimensional perturbation correlation IR spectroscopy (2D-PCIS) was first used to characterize the evolution process of the functional groups in cellulose during pyrolysis. The results showed that the degradation of carbon skeleton was prior to the dehydration of free hydroxyls after the destruction of hydrogen bond networks during pyrolysis.

Formula: C6H12O6On September 15, 2021 ,《Chemical structure and anti-inflammatory activity of a branched polysaccharide isolated from Phellinus baumii》 was published in Carbohydrate Polymers. The article was written by Sun, Yuqing; Huo, Jinxi; Zhong, Shi; Zhu, Jianxun; Li, Yougui; Li, Xiaojun. The article contains the following contents:

Phellinus baumii is used to treat inflammatory bowel disease (IBD) and gastroenteritis. In this study, a 46 kDa heteropolysaccharide SHPS-1 was isolated from fruiting bodies of P. baumii. SHPS-1 consisted of arabinose, mannose, glucose, and galactose at a molar ratio of 2.2:15.7:49.3:32.8. SHPS-1 had a backbone containing 1,3-linked β-D-Glcp and 1,6-linked α-D-Galp residues, and Araf, Manp and Galp units were attached as oligosaccharidic side chains to the backbone at C-6 of some glucopyranoses. SHPS-1 decreased phosphorylation level of STAT-1 and expression levels of STAT-1 targeted genes such as iNOS and TNF-α in lipopolysaccharide-stimulated macrophage RAW 264.7 cells. Furthermore, SHPS-1 promoted the expression of IL-10 and macrophage mannose receptor CD 206, markers of tissue repairing macrophages. SHPS-1 alleviated ulcerative colitis in mice by decreasing pro-inflammatory genes and increasing anti-inflammatory and tissue repairing genes. Collectively, SHPS-1 polysaccharide from P. baumii had anti-inflammatory activity and can potentially treat IBD. In the experiment, the researchers used rel-(3R,4S,5S,6R)-6-(Hydroxymethyl)tetrahydro-2H-pyran-2,3,4,5-tetraol(cas: 54-17-1Formula: C6H12O6)

In 2016,Muench, Falk; Felix, Eva-Maria; Rauber, Markus; Schaefer, Sandra; Antoni, Markus; Kunz, Ulrike; Kleebe, Hans-Joachim; Trautmann, Christina; Ensinger, Wolfgang published 《Electrodeposition and electroless plating of hierarchical metal superstructures composed of 1D nano- and microscale building blocks》.Electrochimica Acta published the findings.Computed Properties of C4H12KNaO10 The information in the text is summarized as follows:

The fabrication of ordered superstructures composed of nano- and microscale building blocks is of tremendous interest. The authors present a versatile approach for the synthesis of hierarchical and free-standing metal architectures of high structural complexity. Using the ion-track etching technique, hierarchically porous polycarbonate membranes were obtained, which are employed as nanocasting templates. Pore filling is accomplished by the two complementary wet-chem. techniques electrodeposition and electroless plating. Depending on the pore filling mechanism and the template structure, a wide range of novel metal nano-/micro-architectures can be realized. The products can be characterized as hierarchical assemblies of 1-dimensional structures (nanotubes, nanowires, microwires, nanorods). With electrodeposition, complete pore filling is achieved, which gave wire-based morphologies. Special attention is dedicated to the controlled partial filling of the pores with electroless plating, which allows the simultaneous deposition of tubes and – depending on the conformity of the plating reaction and the deposition time – narrower arrays of tubes, wires or rods. To demonstrate the favorable functional properties of the obtainable products, a Ag-based wire-tube assembly is employed in the enzyme-free and selective electrochem. detection of H2O2. An excellent sensitivity of 1340 μA mM-1 cm-2 and a fast response time of <2 s is achieved, which is explained by the absence of binders, the well-accessible, open-pored structure, the presence of continuous conduction pathways and the high surface area of the material.
