Shiels, Oisin J.;Kelly, P. D.;Bright, Cameron C.;Poad, Berwyck L. J.;Blanksby, Stephen J.;da Silva, Gabriel;Trevitt, Adam J. research published 《 Reactivity Trends in the Gas-Phase Addition of Acetylene to the N-Protonated Aryl Radical Cations of Pyridine, Aniline, and Benzonitrile》, the research content is summarized as follows. A key step in gas-phase polycyclic aromatic hydrocarbon (PAH) formation involves the addition of acetylene (or other alkyne) to σ-type aromatic radicals, with successive additions yielding more complex PAHs. A similar process can happen for N-containing aromatics In cold diffuse environments, such as the interstellar medium, rates of radical addition may be enhanced when the σ-type radical is charged. This paper investigates the gas-phase ion-mol. reactions of acetylene with nine aromatic distonic σ-type radical cations derived from pyridinium (Pyr), anilinium (Anl), and benzonitrilium (Bzn) ions. Three isomers are studied in each case (radical sites at the ortho, meta, and para positions). Using a room temperature ion trap, second-order rate coefficients, product branching ratios, and reaction efficiencies are measured. The rate coefficients increase from para to ortho positions. The second-order rate coefficients can be sorted into three groups: low, between 1 and 3 x 10-12 cm3 mol.-1 s-1 (3Anl and 4Anl); intermediate, between 5 and 15 x 10-12 cm3 mol.-1 s-1 (2Bzn, 3Bzn, and 4Bzn); and high, between 8 and 31 x 10-11 cm3 mol.-1 s-1 (2Anl, 2Pyr, 3Pyr, and 4Pyr); and 2Anl is the only radical cation with a rate coefficient distinctly different from its isomers. Quantum chem. calculations, using M06-2X-D3(0)/6-31++G(2df,p) geometries and DSD-PBEP86-NL/aug-cc-pVQZ energies, are deployed to rationalize reactivity trends based on the stability of prereactive complexes. The G3X-K method guides the assignment of product ions following adduct formation. The rate coefficient trend can be rationalized by a simple model based on the prereactive complex forward barrier height.

Silica supported N-doped carbon layers encapsulating Co-Cu nanoparticles (Co1Cux@CN/SiO2) were prepared by a one-step impregnation of Co(NO3)2·6H2O, Cu(NO3)2·3H2O, urea and glucose, following in situ carbothermal reduction Effects of Cu contents on the catalytic performance of the Co1Cux@CN/SiO2 catalysts were investigated for selective hydrogenation of p-chloronitrobenzene to p-chloroaniline. The Co1Cu0.30@CN/SiO2 with Cu/Co molar ratio of 0.30:1 presented much higher activity and stability than the monometallic Co@CN/SiO2 catalyst. The addition of Cu into Co1Cux@CN/SiO2 catalysts had favorable effects on the formation of highly active Co-N sites and N-doped carbon layer. The role of the N-doped carbon layer was to protect the Co from oxidation by air, and the Co1Cu0.30@CN/SiO2 could be reused for at least 12 cycles without decrease in catalytic efficiency. Mechanistic and in situ IR studies revealed that the interaction effect between the Co and Cu atoms made the surface of Co highly electron rich, which decreased adsorption of halogen groups and resulting in the enhanced selectivity during chemoselective hydrogenation of halogenated nitroarenes for a wide scope of substrates.

The recyclable nanomagnetic Pd-complex PAMAM G0-Pd@γ-Fe2O3 is reported for catalytic C-C cross-coupling reactions of challenging substrates. Mainly, a great variety of aryl chlorides could be used as substrates for Suzuki-Miyaura and Mizoroki-Heck reactions under mild reaction conditions (60-90°C) and low catalyst loading (<1 mol% Pd) in aqueous media. A series of biaryls I [R = H, 4-MeO, 4-Me, 4-NO2, 3-NO2, 4-cyano, R1 = 4-MeO, 4-Me, H, 4-CHO, 4-COMe, 4-NO2, 4-cyano, 3-NH2, 3-CF3, 3-NO2, 2-Me, 2-CO2H, 2-NO2, 2-Me-4-NO2] was obtained via Pd-complex catalyzed Suzuki-Miyaura cross-coupling reaction of phenylboronic acids with aryl halides. Also, styrenes and trans-Bu cinnamates II [R3 = 4-Me, 4-MeO, H, 4-cyano, 4-NO2, 4-Br, 4-CO2Et, 4-COMe, 2-Me, R4 = Ph; R3 = H, 4-HO, 4-NH2, 4-MeO, 4-Me, 4-Cl, 3-Me, 3-NO2, R4 = CO2Bu] were obtained via Pd-complex catalyzed Mizoroki-Heck cross-coupling reaction of alkenes and aryl halides. The presence of numerous polar groups in the polymer matrix increased the solubility of the catalyst in water, thus facilitating its operation in aqueous environments. The immobilization of the catalyst on the surface of a magnetic platform allows its effective recovery and reuse without significant loss of catalytic activity for at least six cycles with total leaching of <1% palladium metal, meeting the requirements for acceptable metal residues in the pharmaceutical industry.

COA of Formula: C2H4INO, 2-Iodoacetamide is a synthetic retinoid that binds to the DNA of cells, altering transcription. It also has been found to be effective in treating bowel disease and has been shown to have dna binding activity. The compound was synthesized by attaching iodine molecules to acetamide. 2-Iodoacetamide targets the protein thiols on the surface of cells, which are responsible for oxidation and damage due to reactive oxygen species (ROS). This compound is metabolized by alcohol dehydrogenase and can be used as a biological sample or natural compound is a compound used as an electrophile for covalent modification of nucleophilic residues on proteins (cysteine, methionine, histidine). When modifying the active-site residues of cysteine proteases, α-Iodoacetamide acts as an irreversible inhibitor of these enzymes.

2-Iodoacetamide used in peptide mapping because it covalently binds with thiols in cysteine residues, thereby preventing disulfide bond formation. By virtue of reaction with cysteine, it is an irreversible inhibitor of enzymes with cysteine at the active site. Also reacts with histidine residues though much more slowly, and this activity is responsible for inhibition of ribonuclease.

V.;Hansson, Gunnar C.;Recktenwald, Christian V. research published 《 Transglutaminase 3 crosslinks the secreted gel-forming mucus component Mucin-2 and stabilizes the colonic mucus layer》, the research content is summarized as follows. The colonic mucus layer is organized as a two-layered system providing a phys. barrier against pathogens and simultaneously harboring the commensal flora. The factors contributing to the organization of this gel network are not well understood. In this study, the impact of transglutaminase activity on this architecture was analyzed. Here, we show that transglutaminase TGM3 is the major transglutaminase-isoform expressed and synthesized in the colon. Furthermore, intrinsic extracellular transglutaminase activity in the secreted mucus was demonstrated in vitro and ex vivo. Absence of this acyl-transferase activity resulted in faster degradation of the major mucus component the MUC2 mucin and changed the biochem. properties of mucus. Finally, TGM3-deficient mice showed an early increased susceptibility to Dextran Sodium Sulfate-induced colitis. Here, we report that natural isopeptide crosslinking by TGM3 is important for mucus homeostasis and protection of the colon from inflammation, reducing the risk of colitis.

Sen, Abhijit;Dhital, Raghu N.;Sato, Takuma;Ohno, Aya;Yamada, Yoichi M. A. research published 《 Switching from Biaryl Formation to Amidation with Convoluted Polymeric Nickel Catalysis》, the research content is summarized as follows. A stable, reusable, and insoluble poly(4-vinylpyridine) nickel catalyst (P4VP-NiCl2) was prepared through the mol. convolution of poly(4-vinylpyridine) (P4VP) and nickel chloride. The authors proposed a coordination structure of the Ni center in the precatalyst based on elemental anal. and Ni K-edge XANES, and they confirmed that it is consistent with Ni K-edge EXAFS. The Suzuki-Miyaura-type coupling of aryl halides and arylboronic esters proceeded using P4VP-NiCl2 (0.1 mol % Ni) to give the corresponding biaryl compounds in up to 94% yield. Surprisingly, when the same reaction of aryl halides and arylboronic acid/ester was carried out in the presence of amides, the amidation proceeded predominantly to give the corresponding arylamides in up to 99% yield. In contrast, the reaction of aryl halides and amides in the absence of arylboronic acid/ester did not proceed. P4VP-NiCl2 successfully catalyzed the lactamization for preparing phenanthridinone. P4VP-NiCl2 was reused five times without significant loss of catalytic activity. Pharmaceuticals, natural products, and biol. active compounds were synthesized efficiently using P4VP-NiCl2 catalysis. Nickel contamination in the prepared pharmaceutical compounds was not detected by ICP-MS anal. The reaction was scaled to multigrams without any loss of chem. yield. Mechanistic studies for both the Suzuki-Miyaura and amidation reactions were performed.

144-48-9, 2-Iodoacetamide is a synthetic retinoid that binds to the DNA of cells, altering transcription. It also has been found to be effective in treating bowel disease and has been shown to have dna binding activity. The compound was synthesized by attaching iodine molecules to acetamide. 2-Iodoacetamide targets the protein thiols on the surface of cells, which are responsible for oxidation and damage due to reactive oxygen species (ROS). This compound is metabolized by alcohol dehydrogenase and can be used as a biological sample or natural compound is a compound used as an electrophile for covalent modification of nucleophilic residues on proteins (cysteine, methionine, histidine). When modifying the active-site residues of cysteine proteases, α-Iodoacetamide acts as an irreversible inhibitor of these enzymes.

2-Iodoacetamide used in peptide mapping because it covalently binds with thiols in cysteine residues, thereby preventing disulfide bond formation. By virtue of reaction with cysteine, it is an irreversible inhibitor of enzymes with cysteine at the active site. Also reacts with histidine residues though much more slowly, and this activity is responsible for inhibition of ribonuclease.

Schumacher, Christian Eric;Rausch, Marvin;Greven, Tobias;Neudorfl, Jorg-Martin;Schneider, Tanja;Schmalz, Hans-Guenther research published 《 Total Synthesis and Antibiotic Properties of Amino-Functionalized Aromatic Terpenoids Related to Erogorgiaene and the Pseudopterosins》, the research content is summarized as follows. Following a concept recently introduced by Hergenrother, the present study addresses the question of whether certain antimicrobially active aromatic (marine) natural products can be converted into more potent broad-spectrum antibiotics by introducing an aminoalkyl side chain. To this end, phenolic mono- and sesquiterpenoids (including carvacrol, xanthorrhizol, and 7-hydroxycalamene) as well as the diterpenes 7-hydroxyerogorgiaene and 9-deoxypseudopterosin A were converted into amino-functionalized analogs that display either an amino-Me or a 2-amino-ethoxy substituent in place of (or next to) the OH group. This was achieved either by Pd-catalyzed nitromethylation/reduction of the aryltriflates, by O-alkylation of the phenols with bromoacetonitrile and subsequent reduction, or by ortho-hydroxymethylation/amination. During the study, an efficient enantioselective total synthesis of 7-hydroxyerogorgiaene (I, 8 steps, 29% overall yield) and 9-deoxypseudopterosin aglycon (II, 9 steps, 30% overall yield) was elaborated using an asym. cobalt-catalyzed hydrovinylation (91% ee) of 3-methoxy-4-methylstyrene as the chirogenic step. Other important C-C bond forming steps include a Pd-catalyzed Suzuki cross-coupling and diastereoselective Lewis acid-mediated cyclization reactions. A total of 16 amino derivatives of natural products were prepared and subsequently tested for their antibacterial properties. Some of the diterpene-derived amines showed high efficacy, not only against Gram-pos. (S. aureus SG511, S. aureus HG003, B. subtilis 168; MIC=0.5 to 2μg/mL), but also against Gram-neg. bacterial strains (E. coli K12; E. coli I-11276b; MIC=8 to 32μg/mL). This clearly supported the underlying working hypothesis.
