Saffron is an edible spice with highly appreciated sensory and antioxidant properties. One of the most representative redox species found in saffron extracts is crocin, whose content is used to evaluate the quality and value of the resulting spice. In this study, a voltammetry method based on the direct detection of crocin at a bare glassy carbon electrode is presented. The principle of the method is based on the monitoring of the anodic wave exhibited by crocin (0.1?1.0 mM) after its mixing with the azo radical initiator AAPH (20 mM) in ethanol:acetonitrile (1 : 1) solution. The decay rate of the anodic peak (E=+434 mV vs. Ag/Ag+), as a result of the consumption of crocin by AAPH, was used as index of the hydrogen transfer capacity and, thus, of its antioxidant activity. With a decay rate of k=0.02 h?1, crocin exhibits only a weak antioxidant activity in comparison with tocopherols (k=0.13 h?1), but still sufficient to protect against the oxidation of safranal, a further redox species found in saffron extracts and mainly responsible for its flavor. The proposed approach was finally applied to discriminate saffron extract samples from different geographical origins. The proposed approach is suitable to characterize the quality of saffron extracts and estimate its antioxidant properties.

A carbon paste electrode was modified with the ionic liquid 1-methyl-3-octyl imidazolium hexafluorophosphate and it was applied for study the electrocatalytic oxidation and voltammetric determination of the drug sulfamethazine. The developed modified electrode was characterized using cyclic voltammetry and scanning electron microscopy. The oxidation of sulfamethazine at the surface of modified electrode occurs at lower potentials than that of an unmodified carbon paste electrode, and both an enhancement of the anodic peak current and a signal narrower and better defined with the modified electrode were observed. Accordingly, a method for the determination of sulfamethazine was developed using differential pulse voltammetry, at pH 11 and with an accumulation time of 3 min. The oxidation of sulfamethazine exhibited a dynamic range between 30 and 300 mug/mL and detection and quantitation limits of 54 and 61 mug/mL, respectively. The method was applied to the determination of sulfamethazine in a veterinary commercial solution.

Interaction of the antimalarial chloroquine (CQ) with ferriprotoporphyrin IX, Fe(III)PPIX, was investigated in aqueous solution (pH 7.4) and as a precipitate from aqueous medium at pH 5.0. In solution, spectrophotometric titrations indicated strong association (logKobs 13.3 ± 0.2) and a Job plot gave a stoichiometry of 1:2 CQ:Fe(III)PPIX. UV-visible absorbance and magnetic circular dichroism spectra of the complex were compared to various Fe(III)PPIX species. Close similarity to the spectra of the mu-oxo dimer, mu-[Fe(III)PPIX]2O, was revealed. The induction of this species by CQ was confirmed by magnetic susceptibility measurements using the Evans NMR method. The observed low-magnetic moment (2.25 ± 0.02 muB) could only be attributed to antiferromagnetically coupled Fe(III) centers. The value was comparable to that of mu-[Fe(III)PPIX]2O (2.0 ± 0.1 muB). In the solid-state, mass spectrometry confirmed the presence of CQ in the complex. Dissolution of this solid in aqueous solution (pH 7.4) resulted in a solution with a UV-visible spectrum consistent with the same 1:2 stoichiometry observed in the Job plot. Magnetic susceptibility measurements made on the solid using an Evans balance produced a magnetic moment (2.3 ± 0.1 muB) consistent with that in solution. Diffusion coefficients of CQ and its complex with Fe(III)PPIX were measured in aqueous solution (3.3 ± 0.3 and 0.6 ± 0.2 × 10- 10 m 2·s- 1, respectively). The latter was used in conjunction with an empirical relationship between diffusion coefficient and molar volume to estimate the degree of aggregation. The findings suggest the formation of a 2:4 CQ:Fe(III)PPIX complex in aqueous solution at pH 7.4.

In the field of manufacturing technology an exciting revolution is in progress today. The different methods of the so called additive manufacturing (AM) technologies are under fast developments. Several versions of them are called 3D printing. Less interest has been given to study the corrosion resistance character of the differently made 3D printed metal alloy items. In this work corrosion behaviour of 3D printed AlMg4.5Mn0.7 alloy samples were investigated. Conventional methods like open circuit potential measurements, Tafel plots taking and scanning electrochemical microscopy (SECM) ? with pH measuring tungsten micro-tip and micro-disc type Pt electrode were used. The metal samples were embedded in epoxy resin. 2D SECM images and line scans were made to see the local changes of oxygen concentration. Flame atomic absorption spectroscopy was used for measuring the metal composition of manufacturing wire and printed sample. The local activity of the surface spots were measured using approach curves recorded in case of ferrocene methanol mediator.

Aims: Heme oxygenase-1 (HO-1), an endogenous cytoprotective enzyme, is reported that can be localized in mitochondria under stress, contributing to preserve mitochondrial function. Mitochondrial quality control (QC) is essential to cellular health and recovery linked with redox homeostasis. Recent studies reported that phosphoglycerate mutase family member (PGAM) 5, a mitochondria-resident phosphatase, plays critical role in mitochondrial homeostasis. Therefore, we aim to investigate cytoprotective mechanisms of HO-1 in I/R-induced hepatic injury focusing on mitochondrial QC associated with PGAM5 signaling. Main methods: Mice were subjected to 60 min of hepatic ischemia followed by 6 h reperfusion and were pretreated twice with hemin (HO-1 inducer, 30 mg/kg) or zinc protoporphyrin (ZnPP; HO-1 inhibitor, 10 mg/kg) 16 and 3 h before ischemia. Key findings: I/R increased hepatic and mitochondrial HO activity, which was augmented by hemin. I/R-induced hepatocellular and mitochondrial damages were attenuated by hemin and augmented by ZnPP. Meanwhile, I/R increased mitochondrial biogenesis, as evidenced by increased mitochondrial DNA contents and mitochondrial transcription factor A protein expression. Hemin augmented these results. I/R impaired mitophagy, as indicated by decreases in Parkin protein expression and the number of mitophagic vacuoles. These changes were attenuated by hemin. Hemin attenuated the I/R-induced increase in mitochondrial fission-related protein, dynamin-related protein 1, and the decrease in PGAM5 protein expression. Furthermore, PGAM5 siRNA abolished the effect of HO-1 on mitochondrial QC in HepG2 cells subjected to hypoxia/reoxygenation. Significance: Our findings suggest that HO-1 protects against I/R-induced hepatic injury via regulation of mitochondrial QC by PGAM5 signaling.

The development of a practical synthesis of 1?-(diphenylphosphino)-1-aminoferrocene (2) and its P-borane adduct (2B) allowed the facile preparation of 1?-(diphenylphosphino)-1-isocyanoferrocene (1). This compound combining two specific soft-donor moieties was studied as a ligand for univalent Group 11 metal ions. The reactions of 1 with AgCl at 1:1 and 2:1 molar ratios only led to the coordination polymer [Ag2(mu-Cl)2(mu(P,C)-1)]n (6), while those with Ag[SbF6] provided the dimer [Ag2(Me2CO-kappaO)2(mu(P,C)-1)2][SbF6]2 and the quadruply-bridged disilver complex [Ag2(mu(P,C)-1)4][SbF6]2 (8), respectively. Addition of 1 to [AuCl(tht)] (tht = tetrahydrothiophene) afforded the mono- and the digold complex, [AuCl(1-kappaP)] (9) and [(mu(P,C)-1)(AuCl)2] (10), depending on the reaction stoichiometry. Finally, the reaction of 1 with [Au(tht)2][SbF6] or halogenide removal from 9 with AgNTf2 led to cationic dimers [Au2(mu(P,C)-1)2]X2 (11, X = SbF6 (a) or NTf2 (b)). Catalytic tests in the Au-mediated isomerization of (Z)-3-methylpent-2-en-4-yn-1-ol to 2,3-dimethylfuran revealed that 11a and 11b are substantially less catalytically active than their analogues containing 1?-(diphenylphosphino)-1-cyanoferrocene as the ligand, most likely due to a stronger coordination of the isonitrile moiety, which prevents dissociation of the dimeric complexes into catalytically active monomeric species.

The result showed that such a combination of chemo- and biocatalysis improved the catalytic yield more than two times compared with that of sole metal catalysis. We will look forword to the important role of 1293-65-8, and how the biochemistry of the body works.HPLC of Formula: C10Br2Fe

SDS of cas: 1293-65-8. Catalysts allow a reaction to proceed via a pathway that has a lower activation energy than the uncatalyzed reaction. Introducing a new discovery about 1293-65-8, Name is 1,1′-Dibromoferrocene

A novel, unsymmetrical 1,1?-disubstituted ferrocenediyl ligand, 1-(diphenylphosphino)-1?-(methoxy)ferrocene (3), featuring phosphine and ether substituents has been synthesized via two different routes and structurally characterized. Its coordination chemistry was investigated by reaction with Rh(I), Cu(I), and group 10 metal precursors. With Ni(II) precursors, chelating complexes are formed in high yield, whereas with Pd(II) and Pt(II) precursors, either chelating complexes or monodentate bis ligand complexes with trans phosphorus ligation may be formed depending on the reaction conditions and metal precursor employed. A similar monodentate trans phosphorus-ligated complex is observed with Rh(I), whereas with Cu(I) precursors, a phosphorus-ligated monodentate bis ligand complex with a coordinated acetonitrile was obtained. Preliminary studies show that 3, in combination with either Pd(II) or Pd(0) precursors, can act as a catalyst for the Suzuki coupling reaction.
