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.

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.

Electric Literature of 1271-48-3, The reactant in an enzyme-catalyzed reaction is called a substrate. Enzyme inhibitors cause a decrease in the reaction rate of an enzyme-catalyzed reaction. 1271-48-3, Name is 1,1′-Ferrocenedicarboxaldehyde, molecular weight is 242.0516. belongs to iron-catalyst compound, In an Article，once mentioned of 1271-48-3

Lithioferrocene, 1,1′-dilithioferrocene, lithioruthenocene and 1,1′-dilithioruthenocene all react with N,N-dimethylformamide in diethyl ether to produce the respective aldehydes.The lithiation of the two metallocenes can be steered to maximize the formation of only one of the two aldehydes by choosing either n-butyllithium in the presence of tetramethylethylenediamine (TMEDA) or t-butyllithium (tBuLi) as the metallating reagent: ferrocene mono-aldehydes or 1,1′-dialdehydes are formed with good yields (91percent and 85percent respectively, based on ferrocene), lower yields (50percent) of ruthenocene-1,1′-dialdehyde were obtained under the standard conditions, because the 1,3,1′-trialdehyde also formed in significant (19percent) amounts.Monolithiation by nBuLi and the formation of the ruthenocene monoaldehyde (yield, 66percent) are favoured when TMEDA is used in only catalytic amounts; lithiation of ruthenocene by tBuLi selectively leads to monolithioruthenocene and the mono-aldehyde (yield, 91percent).The products are easily purified by column chromatography.The simplicity and the high yield of these reactions make them much more desirable than the previously known multistep procedures.

Application of 1273-86-5, hemistry, like all the natural sciences, begins with the direct observation of nature— in this case, of matter. In a document type is Article, molecular formula is C11H3FeO, molecular weight is 206.99, and a compound is mentioned, 1273-86-5, Ferrocenemethanol, introducing its new discovery.

Novel conjugates of ferrocene with uracil, 5-fluorouracil, tegafur, or acyclovir are reported. Their synthesis involved (i) the azide-alkyne 1,3-dipolar cycloaddition or (ii) the formation of the ester linkage. For the first time, we present an in-depth insight into the supramolecular interactions between beta-cyclodextrin and ferrocene-nucleobase derivatives. Spectroscopic and voltammetric analyses performed within this work suggested that the ferrocene or adamantane unit of the conjugates interacted with the beta-cyclodextrin’s inner cavity. The methods applied for the supramolecular studies included 1H-1H ROESY NMR, 1H NMR titration, Fourier-transform infrared spectroscopy, cyclic voltammetry, fluorescence spectra titration, and 1H DOSY NMR. 1H DOSY NMR was also employed to evaluate the apparent binding constants for all the complexes. The ferrocene-acyclovir conjugate Fc-5 featured the highest apparent binding constant value among all the complexes tested.

Application of 1273-86-5, Enzymes are biological catalysts that produce large increases in reaction rates and tend to be specific for certain reactants and products. 1273-86-5, Name is Ferrocenemethanol, molecular weight is 206.99. In an Article，once mentioned of 1273-86-5

A new method for the hydrosilylation of alkynes controlled by a platinum catalyst with a monophosphine ligand (called TBSO-MOP) was explored. The platinum-catalyzed multicomponent and sequential silylation reaction involving alkynes, alcohols, and dihydrosilanes resulted in the highly stereoselective and high-yielding construction of functional (E)-vinylsilyl ethers. Moreover, the one-pot bis-hydrosilylation of terminal alkynes with dihydrosilanes was also achieved with the same platinum catalyst system.

Synthetic Route of 1273-86-5, 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. 1273-86-5, Name is Ferrocenemethanol, molecular weight is 206.99. molecular formula is C11H3FeO. In an Article，once mentioned of 1273-86-5

The diiron bridging vinyliminium complexes [Fe2{mu- eta1:eta3-C=N(Me)2C(R?)=C(R?)} (mu-CO)(CO)(Cp)2][SO3CF3] (R? = H, R? = SiMe3, 3a; R? = H, R? = Tol =4-MeC 6H4, 3b; R? = Me, R? = Me, 3c; R? = SPh, R? = Me, 3d; R? = H, R? = Fc = [Fe(C5H 4)(Cp)], 6e) react with propargyl alcohol (HC?CCH 2OH), in refluxing toluene, affording the polysubstituted ferrocenes as mixtures of two isomeric forms: [1-NMe2-2-R?-3-R?-5- CH2OCH2C?CH-Fc] (R? = H, R? = SiMe 3, 6a; R? = H, R? = Tol, 6b; R? = Me, R? = Me, 6c; R? = SPh, R? = Me, 6d, R? = H, R? = Fc, 6e) and [1-NMe2-2-R?-3-R?-4-CH2OCH2C? CH-Fc] (R? = H, R? = SiMe3, 7a; R? = H, R? = Tol, 7b; R? = Me, R? = Me, 7c; R? = SPh, R? = Me, 7d) in overall yields of about 55-65%. Formation of the functionalized cyclopentadienyl in the ferrocene products takes place through the assembly of two propargyl units with the bridging vinyliminium ligand: one alkynol is incorporated by a [3 + 2] cycloaddition with the bridging C3 ligand; a second alkynol unit gives rise to a pendant chain through -OH substitution. Investigations show that the substitution step is catalyzed by the parent diiron complex itself or by a mononuclear iron fragment (likely the Fp+ complex). The pendant propargyl chain has been exploited to connect the ferrocene to other molecular fragments: in particular, the reaction of 6a with 4-biphenyl azide, by copper-catalyzed azide-alkyne cycloaddition (CuAAC), leads to the formation of the triazole-functionalized ferrocene [1-NMe 2-2-CH2OCH2-N3(C6H 4Ph)C2H-4-SiMe3-Fc] (12). Moreover, 6a reacts with Co2(CO)8, affording the complex [Co 2{mu-eta2-HC?CR}(CO)6] (13), (HC?CR = 6a), where the alkyne adopts a eta2 coordination to a dicobalt hexacarbonyl fragment. The molecular structure of 7a has been determined by X-ray diffraction studies.

One of the major reasons for studying chemical kinetics is to use measurements of the macroscopic properties of a system, name: Ferrocenemethanol, In homogeneous catalysis, catalysts are in the same phase as the reactants. In a article, mentioned the application of 1273-86-5, Name is Ferrocenemethanol, molecular formula is C11H3FeO

A dual-stream flow injection method has been developed for electrochemical detection of ferrocene derivatives in flow streams. The method is based on a previously described electrochemical amplification method in which currents for analyte oxidation are enhanced by rapid analyte regeneration via a solution-phase electron exchange reaction with a sacrificial reagent. The use of two independent flow channels in the present method, one to carry the analyte and another to supply the sacrificial reagent, eliminates the necessity of spiking samples and calibration standards with sacrificial reagent to avoid injection transients. Hydrodynamic voltammograms were recorded for a series of injections of hydroxymethylferrocene (HMFc, a model ferrocene analyte) into the carrier stream in the presence and absence of ferrocyanide (which serves as sacrificial reagent) in the reagent stream. From these voltammograms an optimum detection potential for HMFc of +0.8 V versus Ag|AgCl|KClsat was selected. Two different concentrations of sacrificial reagent were tested for a range of HMFc concentrations between 1 × 10-3 and 1 × 10-8 M for which both unamplified and amplified peaks could be detected. An amplification factor of approximately 300 was obtained for a 1 × 10-8 M HMFc injection with 2 × 10-4 M ferrocyanide present in the reagent stream.

Recommanded Product: 1271-51-8. Catalysts allow a reaction to proceed via a pathway that has a lower activation energy than the uncatalyzed reaction. Introducing a new discovery about 1271-51-8, Name is Vinylferrocene

X-ray absorption spectroscopy (XAS) was used to study the electrochemical incorporation of perrhenate anion, from a 0.1 M NH4ReO4 solution, into poly(vinylferrocene) (PVFc) and a modified PVFc (a copolymer of 30% t-butyl acetylferrocene and 70% t-butyl divinyl ferrocene). The polymers were deposited on a carbon cloth current collector from a solution of the polymers in CH2Cl2. In situ XAS measurements were done at the Fe K edge on the reduced polymers and at 0.9 V vs. Ag/AgCl. Ex situ XAS was done at the Re L3 edge after oxidation of the polymers at 0.9 V. The oxidized electrodes were washed in water to remove dissolved NH4ReO4 in the electrode pores. XAS was done both on wet-washed electrodes and on electrodes that were dried. XAS showed that at 0.9 V the Fe was oxidized from a ferrocene to a ferrocenium moiety and the Fe-C bond distance increased from 2.05 to 2.08 A. Both the X-ray absorption near-edge spectroscopy and extended X-ray absorption fine structure (EXAFS) results are consistent with having >75% of the ferrocene moieties in the polymer oxidized at 0.9 V. The Fe K-edge EXAFS showed no direct indication of interaction of Fe with ReO4-. At the Re L3 edge the only indication of interaction of ReO4- with the polymers was a slight change in the XANES features.

Chemistry is a science major with cience and engineering. The main research directions are preparation and modification of special coatings, and research on the structure and performance of functional materials. In a patent, 1271-48-3, name is 1,1′-Ferrocenedicarboxaldehyde, introducing its new discovery. Application In Synthesis of 1,1′-Ferrocenedicarboxaldehyde

The bitopic ligand 1,1?-bis(dipyrazol-1-ylmethyl)ferrocene, Fe[C 5H4CH(pz)2]2 (1; pz = pyrazolyl ring), has been prepared by the reaction of 1,1?-ferrocenedicarbaldehyde and 1,1?-carbonyldipyrazole. In the solid state, the bis(pyrazolyl) methane moieties are in an antiperiplanar eclipsed orientation. The molecules are organized into a three-dimensional array by pi…pi, weak C-H-…N hydrogen bonding, and C-H…pi interactions. The reactions between 1 and AgBF4, AgPF6, AgSO3CF 3, or AgSbF6 yield {Fe[C5H 4CH(pz)2]2AgBF4}n (2), {Fe[C5H4CH(pz)2]2AgPF 6}n (3), {Fe[C5H4CH(Pz) 2]2AgSO3CF3}n (4), and {Fe[C5H4CH(pz2]2AgSbF 6}n (5), respectively. The solid-state structures consist of coordination polymers with compounds 2 and 3 arranged in helical chains, while the chains in 3·1/2Et2O, 4·1.5C6H 6,5·1/2Et2Et2O, and 5·1/2C 6H6 are nonhelical. In these structures, the ferrocenyl groups adopt a similar orientation, where the angle between CH(pz)2 groups is confined to the range of 85-99 and the silver pyrazolyl coordination spheres are also in very similar distorted-tetrahedral arrangements. Both structural types form three-dimensional supramolecular structures organized by weak hydrogen bonds, pi…pi stacking, and CH…pi interactions. In the helical form, the anions reside in the pockets formed by the close-packed chains, whereas in the nonhelical form, sizable channels, which contain the solvent molecules and the anions, are located between the chains.
