This paper describes an electrochemically mediated enzyme reaction of polyethyleneglycol (PEG)-modified galactose oxidase (GAO) in organic solvents as well as in an aqueous solution. Catalytic currents were investigated in the presence of ferrocene derivatives as mediators and PEG-modified GAO in several organic solvents. The catalytic current due to the mediated enzyme reaction was obtained in acetonitrile, N,N-dimethylformamide, N,N-dimethylacetamide and dimethylsulfoxide (DMSO). Stability tests of PEG-modified GAO in organic solvents demonstrated that the initial Ik/Id value was highest in acetonitrile; however, it gradually decreased. The PEG-modified GAO was more stable in DMSO. Reactivities of several mediators were investigated. Although a positively charged mediator indicated high reactivity in the aqueous solution, non-charged mediators such as ferrocene dimethanol and n-butyl ferrocene showed the highest activity in organic solvents. Substrate specificity demonstrated that the catalytic activity for benzyl alcohol in acetonitrile was greater than in aqueous solution. The effect of water content in acetonitrile was investigated. The catalytic activity decreased with the increase in water content.

In the present manuscript, the electrochemical behavior of cytochrome c (cyt-c) immobilized onto a phenolic terminated self assembled monolayer (SAM) on a gold electrode is investigated using cyclic voltammetry (CV) and scanning electrochemical microscopy (SECM). The tunneling electron transfer (ET) rate constant between the immobilized protein and the underlying electrode surface, and also the bimolecular ET rate constant between the immobilized protein and a probe has been obtained using approach curves that were obtained by SECM. The approach curves were recorded at different substrate overpotentials in the presence of various concentrations of ferrocyanide as a probe and various surface concentrations of cyt-c; then the standard tunneling ET and bimolecular rate constants are obtained as 3.4 ± 0.3 s-1 and (2.0 ± 0.5) × 107 cm3 mol-1 s-1, respectively.

Reference of 16009-13-5, In heterogeneous catalysis, catalysts provide a surface to which reactants bind in a process of adsorption. In homogeneous catalysis, catalysts are in the same phase as the reactants. In a document type is Article, and a compound is mentioned, 16009-13-5, name is Hemin, introducing its new discovery.

In this article, a new electrochemiluminescent (ECL) biosensor based on a g-C3N4-hemin nanocomposite and hollow gold nanoparticles (HGNPs) was constructed to detect lactate. Firstly, the g-C3N4 nanosheets were prepared through ultrasonication-assisted liquid exfoliation of bulk g-C3N4, which was obtained through polymerizing melamine under 600C. Then, the nanocomposites of g-C3N4 nanosheets and hemin were prepared to modify a glassy carbon electrode. Subsequently, HGNPs were self-assembled onto the electrode for adsorbing lactate oxidase to achieve a lactate biosensor. Due to the excellent catalytic effect of g-C3N4-hemin and HGNPs on the luminol/H2O2 ECL system, the as-prepared biosensor exhibited a good response performance to lactate with a linear range of 1.7 × 10-8 to 5.0 × 10-4 M and a detection limit of 5.5 × 10-9 M. In addition, the prepared ECL biosensor exhibited satisfying reproducibility and stability. The g-C3N4-hemin nanocomposite might have great potential application in a luminol/H2O2 ECL system.

We have synthesized a series of novel SERMs bearing a ferrocenyl unit based on a three-dimensional oxabicyclo[2.2.1]heptene core scaffold. These compounds displayed high receptor binding affinities as well as ERalpha or ERbeta selectivity. In cell proliferation assays, we found that these ligands were cytotoxic at micromolar concentrations in both ER-positive and ER-negative breast cancer cells. On further examination, we found that the antiproliferative effects of compounds 9b, 10h and 11b on MCF-7 cells line does not arise from antiestrogenicity, but rather proceeds through a cytotoxic pathway. Possible mechanisms for the unique activities of these ligands were also investigated by molecular modeling. These new ligands could act as scaffolds for the development of novel anti-breast cancer agents. The Royal Society of Chemistry 2012.

Synthesis of environmentally-sensitive, and therefore smart hydrogels of micro- and nanosize allowed substantial shortening of time of response of these gels to a change in environmental conditions. This made the hydrogels much more attractive and opened new possibilities of their applications. In this paper we present recent developments in ways of construction of micro- and nanogels, their adaptation to particular needs and possibilities of use. The focus was given to individual, spherical particles and very thin layers of gels on solid supports, including electrodes.

Irreversible inhibitors are therefore the equivalent of poisons in heterogeneous catalysis. Product Details of 1271-48-3, Enzyme inhibitors cause a decrease in the reaction rate of an enzyme-catalyzed reaction by binding to a specific portion of an enzyme and thus slowing or preventing a reaction from occurring. In a patent，Which mentioned a new discovery about 1271-48-3

Barbier-type gamma-regiospecific allylation of formylferrocene (1) with allyl bromides in the presence of stannous chloride dihydrate and catalytic cupric chloride in dichloromethane-water (1:1) afforded corresponding ferrocenyl dienes FcCHC(R1)C(R2)CH2 (3-6). On the other hand, similar reactions of 1,1?-bis-formylferrocene (2) yielded oxa-bridged [3]-ferrocenophanes having allyl pendants Fc[CH2C(R2)CH(R1)CH-mu(O)-CHCH (R1)C(R2)CH2] (8-11). The latter appear to result from the dehydration of intermediate homoallylic alcohols. Dehydration could be arrested in case of reaction of 1 and 2 with 1-bromo-3-methyl-but-2-ene, which results in the formation of homoallylic alcohols FcCH(OH)C(Me2)CHCH2 (7) and Fc[CH(OH)C(Me2)CHCH2]2 (12), respectively. All the reactions completely fail in absence of water.
