Exploring the conformational variability in the heme b propionic acid side chains through the effect of a biological probe: A study of the isolated ions

The iron(III) protoporphyrin IX complex with imidazole, a biologically relevant ligand, occupying an axial position, has been studied by infrared multiple photon dissociation (IRMPD) spectroscopy. The complex has been delivered in gas-phase by electrospray ionization (ESI), mass selected in an ion trap, and assayed by IRMPD spectroscopy in two complementary frequency regions. The fingerprint range (900-1900 cm-1) has been scanned using the Orsay free-electron laser beamline (CLIO), while the X-H (X = C,N,O) stretching region (3000-3600 cm-1) has been inspected using a tabletop IR optical parametric oscillator/amplifier (OPO/OPA) laser source. DFT calculations have been performed to obtain a comprehensive pattern of the various potential conformers yielding optimized geometries, relative thermodynamic parameters, and respective IR spectra. The comparison between the IR spectra for representative conformers and the experimental IRMPD features suggests the coexistence of two families of conformers involving different degrees of folding and hydrogen bonding between the two propionic acid functionalities on the periphery of the protoporphyrin IX macrocycle in a ratio depending on environmental conditions such as ESI solvent and temperature. The observed conformational variability of the porphyrin substituents in the naked heme-imidazole complex is consistent with the fine-tuning of the reactivity properties of this important prosthetic group by the specific surroundings in the protein core.

Use of a Cyclometalated Iridium(III) Complex Containing a N?C?N-Coordinating Terdentate Ligand as a Catalyst for the alpha-Alkylation of Ketones and N-Alkylation of Amines with Alcohols

A cyclometalated iridium(III) complex containing a N?C?N-coordinating terdentate ligand [Ir(dpyx-N,C,N)Cl(mu-Cl)]2 was found to be a general and highly effective catalyst for the alpha-alkylation of ketones and N-alkylation of amines with alcohols. In the presence of catalyst (1 mol % Ir) and base (0.2-0.5 equiv), a variety of desirable products were obtained in good yields under an air atmosphere. Notably, this research exhibited the new potential of Ir(III) complexes bearing non-Cp? ligand and will facilitate the progress of the hydrogen autotransfer process.

Nylon nanofibrous membrane for mediated glucose biosensing

This work illustrates how polyamide nanofibrous membranes, prepared by the electrospinning process, can act as a new type of biosensor element. The sensing unit is based on a glassy carbon electrode coated with polyamide nanofibrous membranes, in which glucose oxidase is covalently tethered. The work is carried out by means of transient electrochemical techniques, such as cyclic voltammetry and amperometry, in which ferrocene methanol was employed as mediator. The results show that nanofibrous membranes are an excellent support for the development of biosensors thanks to their high-surface to volume ratio, high porosity and permeability of the cosubstrate and minimal effect on both the biocatalytic kinetics and the selectivity of the biorecognition event. The optimization, characterization, and attractive performance of the nanofibrous biosensor are reported in connection with the detection of glucose in a variety of food beverages.

Application of 1271-51-8, Chemistry is the science of change. But why do chemical reactions take place? Why do chemicals react with each other?

Thermodynamics and kinetics of redox switching of polyvinylferrocene films in perchlorate solutions

Cyclic voltammetry was used to create nonequilibrium populations of different solvation and configurational states of partially oxidized polyvinylferrocene (PVF). Oxidation levels were established by scanning either from a fully reduced state to the desired oxidation level or from a fully oxidized state to the desired level. Coulostatic conditions were then established by opening the external circuit, and subsequent mass and potential changes were followed. The film’s approach to equilibrium involves configurational changes within the polymer and simultaneous and subsequent solvent transfer. At very short times (t a?? 0.2 s) the approach to equilibrium is limited by both solvation and reconfiguration processes. For a short time afterward (0.2 < t/s < 1.0) reconfiguration alone is rate limiting. At intermediate times (1 < t/s < 5) both processes play comparable roles. At long times (r > 5 s) solvation is the controlling step. The electroactive polymer film does not completely reach equilibrium even after 1 h at open circuit as evidenced by continuous small mass changes. These mass changes are the result of water transfer between the polymer film and the bathing electrolyte. A scheme of cubes model rationalizes mechanistic pathways leading to equilibrium. In particular, the observed extrema in mass (solvent population) are predicted. The electrode potential, after 1 h at open circuit, shows nearly Nernstian dependence on the redox composition for film states produced by either anodic or cathodic cyclic voltammetric scans. These Nernst plots are displaced by only a few millivolts because only a weak Nernstian dependence on film water content exists. Films that are 50% oxidized exhibit a sub-Nernstian response with respect to the perchlorate concentration in the bathing solution under permselective conditions.

Aminomethyl-substituted ferrocenes and derivatives: Straightforward synthetic routes, structural characterization, and electrochemical analysis

A variety of aminomethyl-substituted ferrocenes and the parent compounds (iminomethyl)ferrocenes, azaferrocenophanes, and diferrocenylamines can be selectively synthesized from reductive amination of 1,1?-diformylferrocene or formylferrocene. The optimized one- or two-step reactions have delivered 13 new compounds, isolated in 65-97% yields, which include tertiary (ferrocenylmethyl)amines and azaferrocenophanes by using NaBH(OAc)3 as a mild reducing agent and (iminomethyl)ferrocenes and secondary (ferrocenylmethyl)amines by using LiAlH4. X-ray structures of representative members of these ferrocene derivative families have evidenced the preferred conformation adopted by ferrocene backbones, in which surprisingly the steric hindrance is apparently not systematically minimized. 15N NMR measurements on aminomethyl-substituted ferrocenes and derivatives are provided for the first time, establishing benchmark values ranging from -330 to -305 ppm (nitromethane delta 0 ppm). The cyclic voltammetry of these species evidences two clearly distinct oxidation potentials related to the iron(II) center and the amino function. These aminomethyl-substituted ferrocenes are potentially valuable for further ortho-directed functionalization of ferrocene.

Novel dendrimers containing redox mediator: Enzyme immobilization and applications

In this study, new dendrimers with a ferrocene core were produced by means of a divergent method for the immobilization of the glucose oxidase enzyme (GOx). Pt(II)and Pt(IV)ions were attached to the terminal groups of dendrimers. Metal-containing dendrimers, [Fc(MGlu)2-Aph-Pt(II)]and [Fc(MGlu)2-Aph-Pt(IV)], were obtained using the ?template method? with aminophenol and Pt(II)/Pt(IV)cations. These compounds have been characterized by molar conductivity, magnetic susceptibility, FTIR, UV?Vis, 1H NMR and LC-MS methods. The GOx enzyme was immobilized on the Fc(MGlu)2, [Fc(MGlu)2-Aph-Pt(II)]and [Fc(MGlu)2-Aph-Pt(IV)]dendrimers, and the immobilized enzyme optimization parameters (substrate concentration, temperature, pH, reusability and storage capacity)were determined. Their Km (mM)and Vmax (mM.min?1)values were calculated from the Michaelis?Menten equation. The reusability of the immobilized glucose oxidase enzyme was investigated in an artificial urine medium. The research showed that [Fc(MGlu)2-Aph-Pt(II)]retains more than 61.23% of its initial activity after 10 successive cycles, which is a remarkable result.
