A Combined Experimental and Theoretical Study of ESR Hyperfine Coupling Constants for N,N,N',N'-Tetrasubstituted p-Phenylenediamine Radical Cations. Int J Mol Sci 2023; 24:ijms24043447. [PMID: 36834859 PMCID: PMC9967363 DOI: 10.3390/ijms24043447] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/04/2023] [Revised: 01/26/2023] [Accepted: 02/03/2023] [Indexed: 02/11/2023] Open
Abstract
A test set of N,N,N',N'-tetrasubstituted p-phenylenediamines are experimentally explored using ESR (electron spin resonance) spectroscopy and analysed from a computational standpoint thereafter. This computational study aims to further aid structural characterisation by comparing experimental ESR hyperfine coupling constants (hfccs) with computed values calculated using ESR-optimised "J-style" basis sets (6-31G(d,p)-J, 6-31G(d,p)-J, 6-311++G(d,p)-J, pcJ-1, pcJ-2 and cc-pVTZ-J) and hybrid-DFT functionals (B3LYP, PBE0, TPSSh, ωB97XD) as well as MP2. PBE0/6-31g(d,p)-J with a polarised continuum solvation model (PCM) correlated best with the experiment, giving an R2 value of 0.8926. A total of 98% of couplings were deemed satisfactory, with five couplings observed as outlier results, thus degrading correlation values significantly. A higher-level electronic structure method, namely MP2, was sought to improve outlier couplings, but only a minority of couples showed improvement, whilst the remaining majority of couplings were negatively degraded.

Abstract
The formal potentials for the reversible one-electron oxidation of N,N,N',N' tetrasubstituted p-phenylenediamines in acetonitrile have been applied as a test set for benchmarking computational methods for a series of compounds with only small structural differences. The aim of the study is to propose a simple method for calculating the standard oxidation potentials, and therefore, the protocol is progressively developed by adding more terms in the energy expression. In addition, the effect of including implicit solvation models (IEFPCM, CPCM, and SMD), larger basis sets, and correlation methods are investigated. The oxidation potentials calculated using the G3MP2B3 approach with IEFPCM resulted in the best fit (R2 = 0.9624), but the slope of the correlation line, 0.74, is far from the optimal value, 1.00. B3LYP/6-311++G(d,p) and TPSSh/6-311++G(2d,p) yielded only slightly less consistent data (R2 = 0.9388 and R2 = 0.9425), but with much better slopes, 1.00 and 0.94, respectively. We conclude that it is important to investigate the basis set size and treatment of electron correlation when calculating oxidation potentials for N,N,N',N' tetrasubstituted p-phenylenediamines.

Abstract
Electron and proton transfer reactions in enzymes are enigmatic and have attracted a great deal of theoretical, experimental, and practical attention. The oxidoreductases provide model systems for testing theoretical predictions, applying experimental techniques to gain insight into catalytic mechanisms, and creating industrially important bio(electro)conversion processes. Most previous and ongoing research on enzymatic electron transfer has exploited a theoretically and practically sound but limited approach that uses a series of structurally similar (“homologous”) substrates, measures reaction rate constants and Gibbs free energies of reactions, and analyses trends predicted by electron transfer theory. This approach, proposed half a century ago, is based on a hitherto unproved hypothesis that pre-exponential factors of rate constants are similar for homologous substrates. Here, we propose a novel approach to investigating electron and proton transfer catalysed by oxidoreductases. We demonstrate the validity of this new approach for elucidating the kinetics of oxidation of “non-homologous” substrates catalysed by compound II of Coprinopsis cinerea and Armoracia rusticana peroxidases. This study – using the Marcus theory – demonstrates that reactions are not only limited by electron transfer, but a proton is transferred after the electron transfer event and thus both events control the reaction rate of peroxidase-catalysed oxidation of substrates.

Abstract
Redox-active minerals are ubiquitous in the environment and are involved in numerous electron transfer reactions that significantly affect biogeochemical processes and cycles as well as pollutant dynamics. As a consequence, research in different scientific disciplines is devoted to elucidating the redox properties and reactivities of minerals. This review focuses on the characterization of mineral redox properties using electrochemical approaches from an applied (bio)geochemical and environmental analytical chemistry perspective. Establishing redox equilibria between the minerals and working electrodes is a major challenge in electrochemical measurements, which we discuss in an overview of traditional electrochemical techniques. These issues can be overcome with mediated electrochemical analyses in which dissolved redox mediators are used to increase the rate of electron transfer and to facilitate redox equilibration between working electrodes and minerals in both amperometric and potentiometric measurements. Using experimental data on an iron-bearing clay mineral, we illustrate how mediated electrochemical analyses can be employed to derive important thermodynamic and kinetic data on electron transfer to and from structural iron. We summarize anticipated methodological advancements that will further contribute to advance an improved understanding of electron transfer to and from minerals in environmentally relevant redox processes.

Abstract
Carbon nanotubes (CNTs) have been used for various bioelectrochemical applications, presumably for substantial improvement in performance. However, often only moderate results observed, with many governing factors have been considered and suggested yet without much systematic evaluation and verification. In this study, CNT-supported glucose oxidase (CNT-GOx) was examined in the presence of 1,4-benzoquinone (BQ). The intrinsic Michaelis parameters of the reaction catalyzed by CNT-GOx were found very close to those of native GOx. However, the Nafion entrapment of CNT-GOx for an electrode resulted in a much lower activity due to the limited availability of the embedded enzyme. Interestingly, kinetic studies revealed that the biofuel cell employing such an enzyme electrode only generated a power density equivalent to <40% of the reaction capability of the enzyme on electrode. It appeared to us that factors such as electron and proton transfer resistances can be more overwhelming than the heterogeneous reaction kinetics in limiting the power generation of such biofuel cells.

Abstract
We are interested in investigating the applications of biocatalytic mediated reduction of oxygen by oxygenases in films on electrode surfaces, as such reactions can form the basis for biosensors or biocatalytic fuel cell development. Here we present approaches aimed at improving the stability and signal output of such films. These include selection of oxygen reducing biocatalysts which are active under physiological conditions and development of redox mediators which offer the opportunity to tailor the mediator to each enzyme. It was found that for each enzyme Melanocarpus albomyces laccase (MaL), Trametes hirsutus laccase (ThL) or bilirubin oxidase (MvBOD) it was the biocatalytic films mediated by Os(2,2'-bipyridine)(2)Cl.PVI that not only generated the highest current densities compared to Os(4,4'-dimethyl-2,2'-bipyridine)(2)Cl.PVI and Os(4,4'-dichloro-2,2'-bipyridine)(2)Cl.PVI, but also proved to be the most stable over 48 h. Under physiological conditions electrodes constructed from MvBOD generated the highest initial current densities for each of the osmium redox polymers, however these films proved to be the least stable over 48 h. Stability could be improved using surface pre-treatment.

Abstract
High sensitive biosensors for heterocyclic compounds determination were built using oxidases-catalyzed hexacyanoferrate(III) reduction in the presence of these compounds. As oxidases Aspergillus niger glucose oxidase and recombinant Microdochium nivale carbohydrate oxidase were used. The biosensors were build using graphite electrodes and entrapped solution of the oxidases. The sensitivity of the biosensors achieves 5.2-14.5 microA microM-1 cm-2. The detection limit of some heterocyclic compounds was 0.2 microM. The sensitivity of biosensors was 300-10,000 times larger in comparison to hexacyanoferrate(III). To background the scheme of biosensors action kinetics of synergistic substrates oxidation was investigated in homogenous solution. The measurements showed that the rate of the reduction of low reactive substrate (hexacyanoferrate(III)) increased due to synergistic action of high reactive substrates (oxidized heterocyclic compounds). The modeling revealed the limiting step of the process. The increase of hexacyanoferrate(III) reduction rate is determined by the rate of reduced enzymes interaction with oxidized heterocyclic compound. The oxidation of heterocyclic compounds (mediators) with hexacyanoferrate(III) does not limit the process. The analysis of macrokinetics of biosensors action showed that synergistic effect may be realized and high biosensors sensitivity may be achieved if diffusion module of the enzyme reaction with the oxidized mediator and of a cross reaction is larger than 0.5. The calculated relative sensitivity is about three times higher in comparison to experimentally determined that may be caused by the limited stability of oxidized heterocyclic compounds and/or some external diffusion limitation of substrates.

Abstract
New and known homo- and heterodinuclear Ru(II) and Os(II) complexes with 4,4'-bipyridine (4,4'-bpy), pyrazine, and 4-pyCH=CHpy-4' as bridging ligands (LL) of the type [Cl(bpy)(2)M(LL)MCl(bpy)(2)]X(2) (bpy=2,2'-bipyridine; X=PF(6) or BF(4)) have been studied in their capacity to exchange electrons with a reduced active site of glucose oxidase (GO) from Aspergillus niger. Cyclic voltammograms (CVs) of the dimers in the aqueous buffered solution, when compared with CVs of the parent monomeric species [MCl(LL)(bpy)(2)]BF(4) and [MCl(2)(bpy)(2)] which could be generated at pH approximately 7, if the dimers undergo monomerization, indicate that the dimers are the dominating species under such conditions. All electrochemically oxidized dinuclear complexes studied show high rates of oxidation of GO reduced by D-glucose and the corresponding observed second-order rate constants are in the range (5-64)x10(5) M(-1) s(-1) at 25 degrees C. However, these values are lower than that for the mononuclear complex [OsCl(4,4'-bpy)(bpy)(2)]BF(4) (1.1x10(7) M(-1) s(-1)), suggesting that potentially two-electron dimeric mediators have no advantage compared with corresponding monomeric complexes of Ru(II) and Os(II). The structure of [OsCl(4,4'-bpy)(bpy)(2)]BF(4) was confirmed by X-ray crystallography. The monodentate 4,4'-bpy ligand is coordinated cis to the chloride. Its higher reactivity toward reduced GO is accounted for in terms of the antenna effect of the monodentate 4,4'-bpy ligand. The antenna length equals 9.2 A and matches the depth of the enzyme active site pocket of ca. 10 A. The mechanism of the antenna effect is discussed.

Abstract
Biosensors containing recombinant carbohydrate oxidase from Microdochium nivale (rMnO) were developed by means of either chemically modified carbon paste or graphite electrode. 1-(N,N-dimethylamine)-4-(4-morpholine)benzene (AMB) and 1,1'-dimethylferrocene (DMFc) have been used as mediators. The biosensors showed a linear calibration graph up to 18 mM of glucose when operated at 0.04-0.36 V versus a saturated calomel electrode. Almost no change was detected in the sensitivity of the biosensors at pH 7.2-8.1. The biosensors responded to other aldoses in the D-configuration, however, maximal sensitivity of the biosensor was towards D-glucose. The biosensor did not response to polyhydroxylic compounds such as D-mannitol, D-sorbitol and inositol. The advantages of the biosensors based on rMnO in comparison to Aspergillus niger glucose oxidase is a wider linear range, low sensitivity to oxygen and (in some cases) broad specificity.

Abstract
The behavior of resazurin (1) as an electron acceptor in glucose oxidase (GOD)-catalyzed oxidation of glucose under anaerobic conditions is described. When a mixture of 1, glucose, and GOD in phosphate buffer (pH 7.4, 0.1 M) was incubated at 25 degrees C, the resulting solution turned purple to fluorescent pink due to the deoxygenated product, resorufin (2). On incubation of 1 with GOD alone or with H2O2 under essentially the same conditions, no color change was seen, indicating that generation of 2 in the enzymatic reaction is brought about through reduction of 1 by the reduced form (GODred) of GOD, which was also supported by the voltammetric behavior of 1. However, it was found that the enzymatic transformation of 1 to 2 is of no practical use as an indicator reaction for glucose determination using only GOD due to a slow reaction of 1 with GODred. Based on a ping-pong type mechanism with a steady-state approximation, KM and kcat for 1 as an electron acceptor from GODred were estimated to be 15+/-1.3 microM and (5.0+/-0.5) x 10(-2) s(-1), respectively.

Abstract
Steady-state and single-turnover kinetics for the oxidation of the N-substituted phenothiazines (PTs) and phenoxazines (POs) catalyzed by fungal Coprinus cinereus peroxidase and Polyporus pinsitus laccase were investigated at pH 4-10. In the case of peroxidase, an apparent bimolecular rate constant (expressed as k(cat)/K(m)) varied from 1 x10(7)M(-1)s(-1) to 2.6 x 108 M(-1)s(-1) at pH 7.0. The constants for PO oxidation were higher in comparison to PT. pH dependence revealed two or three ionizable groups with pKa values of 4.9-5.7 and 7.7-9.7 that significantly affected the activity of peroxidase. Single-turnover experiments showed that the limiting step of PT oxidation was reduction of compound II and second-order rate constants were obtained which were consistent with the constants at steady-state conditions. Laccase-catalyzed PT and PO oxidation rates were lower; apparent bimolecular rate constants varied from 1.8x 10(5) M(-1) s(-1) to 2.0 x 10(7) M(-1) s(-1) at pH 5.3. PO constants were higher in comparison to PT, as was the case with peroxidase. The dependence of the apparent bimolecular constants of compound II or copper type 1 reduction, in the case of peroxidase or laccase, respectively, was analyzed in the framework of the Marcus outer-sphere electron-transfer theory. Peroxidase-catalyzed reactions with PT, as well as PO, fitted the same hyperbolic dependence with a maximal oxidation rate of 1.6 x 10(8)M(-1)s(-1) and a reorganization energy of 0.30 eV. The respective parameters for laccase were 5.0 x 10(7) M(-1) s(-1) and 0.29 eV.

Abstract
Kinetic determination of protein redox potentials with a mediated continuous-flow column electrolytic spectroelectrochemical technique (CFCESET) is described. In this method, the redox state of the mediator is completely regulated by the continuous-flow column electrolysis, and the homogeneous redox reaction between the mediator and a protein sample in the column is monitored spectroscopically at the downstream of the column. The protein/mediator reaction is in the pseudo-first-order kinetics, and then the rate equation is analytically solved. The kinetic analysis provides the protein redox potential as well as the homogeneous rate constant. In the kinetic measurements, equilibration of the system within the column is not required, which allows the use of increased kinds of mediators. This method was successfully applied to quinoprotein methylamine dehydrogenase containing tryptophan tryptophylquinone (TTQ) as a prosthetic group. The kinetic aspect is also valuable for the thermodynamic analysis with the mediated CFCESET. The half-life time of the kinetics can be utilized to optimize the system for the attainment of the equilibrated state within the column and can provide the assurance that the system is in equilibrium.

Abstract
Quantum size effect was strongly supported by the experiment on correlation between size of gold nanoparticles (below 10 nm) and activity of glucose oxidase attached to them. The attractive enhancement effect of gold nanoparticles on the activity of glucose oxidase was then satisfactorily explained. In this experiment, 2 nm and 6 nm (average diameter) particles were obtained on monolayer matrix. The 2 nm particles proved to be much more able to increase the activity of glucose oxidase.
