In the present work, we report the antibacterial activity of silver nanoparticles (AgNP) coated with the surfactants para-amino-N-((1-decylpyridin-1-ium bromide)-4-yl) benzamide and para-amino-N-((1-dodecylpyridin-1-ium bromide)-4-yl) benzamide (P10 and P12, resp.). P10 and P12-coated AgNP were stable, as confirmed by UV-visible spectrophotometry, transmission electron microscopy, and other surface activity parameters. Both P10 and P12 and the coated AgNP formulations were investigated for their activity against sulfate reducing bacteria (SRB). Overall, our results showed the importance of coating AgNP with surfactants (P10 and P12) in the design and development of new biocides against SRB.

Lexa, Doris’s team published research in Journal of the American Chemical Society in 112 | CAS: 594-81-0

Journal of the American Chemical Society published new progress about 594-81-0. 594-81-0 belongs to bromides-buliding-blocks, auxiliary class Bromide,Aliphatic hydrocarbon chain, name is 2,3-Dibromo-2,3-dimethylbutane, and the molecular formula is C6H12Br2, Application of 2,3-Dibromo-2,3-dimethylbutane.

Lexa, Doris published the artcileOuter-sphere and inner-sphere processes in reductive elimination. Direct and indirect electrochemical reduction of vicinal dibromoalkanes, Application of 2,3-Dibromo-2,3-dimethylbutane, the publication is Journal of the American Chemical Society (1990), 112(17), 6162-77, database is CAplus.

The reduction of vicinal dibromo alkanes (OlX2) is investigated as an example of the dichotomy between outer-sphere and inner-sphere processes in reductive elimination. As a result from the anal. of the kinetic data, outer-sphere reagents such as carbon electrodes and aromatic anion radicals react with vicinal dibromo alkanes according to an electron-transfer mechanism in which the rate-determining step is a concerted electron-transfer bond-breaking reaction leading to the β-bromoalkyl radical. The latter is then reduced very rapidly, in a second step, most probably along another concerted electron-transfer bond-breaking pathway leading directly to the olefin in the heterogeneous case and through halogen atom expulsion in the homogeneous case. In the absence of steric constraints, the reduction goes entirely through the antiperiplanar conformer because the resulting β-bromoalkyl radical is then stabilized by delocalization of the unpaired electron over the C-C-X framework due to a favorable interaction between the pz orbital of the radical carbon and the σ* orbital of the C-Br bond. This interaction is enhanced by alkyl substitution at the reacting carbons, resulting in an approx. linear correlation between the reduction potential and the C-X bond energy of OlX2 on one hand and the vertical ionization potential of the olefin on the other. The stabilization energy is of the order of 0.2-0.3 eV for the anti conformers. It can also be taken as a measure of the rotation barrier around the C-C bond responsible for the loss of stereospecificity in the reduction This competes with the reduction of the two stable conformers of the OlX radicals and for the expulsion of the halogen atom. There is a remarkably good agreement between the ensuing prediction of the E:Z olefin ratio that should be found upon reduction of threo and erythro OlX2 isomers by outer-sphere reagents such as aromatic anion radicals and the exptl. data. Although members of perfectly reversible redox couples, iron(I), iron(0), and cobalt(I) porphyrins offer typical examples of inner-sphere reagents in their reaction with vicinal dibromo alkanes. They indeed react much more rapidly than outer-sphere electron donors (aromatic anion radicals) of the same standard potential. On the basis of steric hindrance experiments, it was shown that they do not react according to an SN2 rate-determining step involving the transient formation of an organometallic species. Complete stereospecificity is obtained, showing that they react along a halonium transfer E2 elimination mechanism rather than by an E1 elimination or a halogen atom transfer mechanism. As shown on a quant. basis, this is related to the large driving force offered to halonium abstraction by the strong affinity of the iron(III) and cobalt(III) complexes toward halide ions. In regard to catalysis, the investigated systems provide typical examples showing the superiority of inner-sphere (chem.) catalysis over outer-sphere (redox) catalysis of electrochem. reactions. Not only is the catalytic efficiency much better since the rate constants of the key steps are larger, given the standard potential of the catalyst, but also selectivity is dramatically improved.

Dendrimers are interesting candidates for various applications because of the high level of control over their architecture, the presence of internal cavities, and the possibility for multivalent interactions. More specifically, zwitterionic dendrimers modified with an equal number of oppositely charged groups have found use in in vivo biomedical applications. However, the design and control over the synthesis of these dendrimers remains challenging, in particular with respect to achieving full modification of the dendrimer. In this work, we show the design and subsequent synthesis of dendrimers that are highly charged while having zero net charge, that is zwitterionic dendrimers that are potential candidates for biomedical applications. First, we designed and fully optimized the synthesis of charge-neutral carboxybetaine and sulfobetaine zwitterionic dendrimers. Following their synthesis, the various zwitterionic dendrimers were extensively characterized. In this study, we also report for the first time the use of XPS as an easy-to-use and quant. tool for the compositional anal. of this type of macromols. that can complement techniques such as NMR and gel permeation chromatog. Finally, we designed and synthesized zwitterionic dendrimers that contain a variable number of alkyne and azide groups that allow straightforward (bio)functionalization via click chem.

Purity, activity and novel inhibitors, Category: bromides-buliding-blocks, the publication is European Journal of Biochemistry (1989), 184(1), 63-8, database is CAplus and MEDLINE.

Methyl-coenzyme-M reductase from M. thermoautotrophicum (strain Marburg) was purified to a stage where, besides the α, β and γ subunits, no addnl. polypeptides were detectable in the preparation Under appropriate conditions the enzyme was found to catalyze the reduction of methyl-CoM with 7-mercaptoheptanoylthreonine phosphate (H-S-HTP) to CH4 at a specific rate of 2.5 μmol min-1 mg protein-1. This finding contradicts a recent report that methyl-CoM reductase is only active when some contaminating proteins are present. The 2 polypeptides encoded by the open reading frames ORF1 and ORF2 of the methyl-CoM reductase transcription unit did not copurify with the α, β and γ subunits. They were neither required nor did they stimulate the activity under the assay conditions. 3-Bromopropanesulfonate (apparent Ki = 0.05 μM) and 2-azidoethanesulfonate (apparent Ki = 1 μM) were found to be 2 new competitive inhibitors of methyl-CoM reductase. Both inhibitors were considerably more effective than the classical 2-bromoethanesulfonate (apparent Ki = 4 μM).

A wide variety of diynols containing tertiary, secondary, and primary propargylic alcs. undergo a cycloisomerization reaction to form dienones and dienals in the presence of a catalytic amount of [CpRu(CH3CN)3]PF6. The formation of five- and six-membered rings is possible using this methodol. E.g., [CpRu(CH3CN)3]PF6 catalyzed the cycloisomerization of diynol I to give 45% dienal II. Secondary diynols react to form single geometrical isomeric dienones and dienals. Primary diynols undergo a cycloisomerization as well as a hydrative cyclization process. The utility of primary diynol cycloisomerization is demonstrated in a synthesis of (+)-α-kainic acid.

Novel phosphine-alkanesulfonate P-O-chelate ligands and their palladium complexes were prepared; the complexes exhibit excellent catalytic activity in Suzuki-Miyaura coupling of aryl bromides and moderate activity in coupling of aryl chlorides with arylboronic acids. Reaction of (2-MeOC6H4)2PLi with Br(CH2)nSO3Na gave bidentate phosphinosulfonates (2-MeOC6H4)2P(CH2)nSO3H (1, 2; n = 2, 3). Complexation of 1 with [Pd2(μ-Cl)212-C8H13OMe)2] gave the palladium(II) complex, [Pd(η12-C8H13OMe)[(2-MeOC6H4)2P(CH2)nSO3OP]] (1a, C8H13OMe = 6-methoxy-1-cycloocten-5-yl), which structure was confirmed by x-ray diffraction anal. Suzuki-Miyaura coupling of R1Br with R2B(OH)2 catalyzed by Pd(OAc)2/L (L = 1, 2) gave the corresponding biaryls R1R2 (R1 = 4MeCOC6H4, Ph, 4-MeOC6H4; R2 = Ph, 1-naphthyl, 4-FC6H4, 4-MeOC6H4) with >99% yields. The ligands 1 and 2 are air-stable as well as water soluble; the coupling reactions were run in neat water and under microwave heating as well.
