Water-dispersible triethylenetetramine-functionalized graphene: Preparation, characterization and application as an amperometric glucose sensor

The triethylenetetramine-functionalized graphene (TFGn) was prepared using graphene oxide (GO) and triethylenetetramine as raw materials through a one-step reaction under alkaline condition. The triethylenetetramine not only acted as cross-linker to combine GO, but also as reductant of GO. The TFGn was characterized by its ultraviolet spectrum (UV), Fourier transform infrared spectroscopy (FTIR), X-ray photoelectron spectroscopy (XPS), X-ray diffraction (XRD), Raman spectroscopy and Scanning electron microscopy (SEM). The results showed that triethylenetetramine was successfully grafted onto the surface of the GO through covalent bonding between amine and epoxy groups. The resultant TFGn was uniformly dispersed in water over several weeks, suggesting that the introduction of amino groups greatly increased the hydrophilicity of TFGn. The triethylenetetramine-functionalized graphene was then applied to fabricate glucose biosensors with IO4- oxidized glucose oxidase (GOx) through layer-by-layer (LBL) self-assembly by the covalent bonding between the aldehyde groups of GOx and amino groups of TFGn. The gold electrodes modified with the (GOx/TFGn)n multilayer films were studied by cyclic voltammetry (CV) and showed outstanding electrocatalytical response to the oxidation of glucose when ferrocenemethanol was used as an artificial redox mediator. The response increased with an increasing number of GOx/TFGn bilayers, indicating that the analytical performance, such as the sensitivity of the glucose biosensor, could be adjusted by tuning the number of deposited GOx/TFGn bilayers. The linear response range of the biosensor constructed with six bilayers of GOx/TFGn to the concentration of glucose can extend to at least 8 mM with a sensitivity of 19.9 muA mM- 1 cm- 2. In addition, the sensor exhibited good stability due to the covalent interactions between the GOx and TFGn.

Labile heme impairs hepatic microcirculation and promotes hepatic injury

Sepsis is a life-threatening clinical syndrome defined as a deregulated host response to infection associated with organ dysfunction. Mechanisms underlying the pathophysiology of septic liver dysfunction are incompletely understood. Among others, the iron containing tetrapyrrole heme inflicts hepatic damage when released into the circulation during systemic inflammation and sepsis. Accordingly, hemolysis and decreased concentrations of heme-scavenging proteins coincide with an unfavorable outcome of critically ill patients. As the liver is a key organ in heme metabolism and host response to infection, we investigated the impact of labile heme on sinusoidal microcirculation and hepatocellular integrity. We here provide experimental evidence that heme increases portal pressure via a mechanism that involves hepatic stellate cell-mediated sinusoidal constriction, a hallmark of microcirculatory failure under stress conditions. Moreover, heme exerts direct cytotoxicity in vitro and aggravates tissue damage in a model of polymicrobial sepsis. Heme binding by albumin, a low-affinity but high-capacity heme scavenger, attenuates heme-mediated vasoconstriction in vivo and prevents heme-mediated cytotoxicity in vitro. We demonstrate that fractions of serum albumin-bound labile heme are increased in septic patients. We propose that heme scavenging might be used therapeutically to maintain hepatic microcirculation and organ function in sepsis.

Ferrocene-appended iridium(III) Complexes: Configuration regulation, anticancer application, and mechanism research

A series of ferrocene-appended half-sandwiched iridium(III) phenylpyridine complexes have been designed and synthesized. These complexes show better anticancer activity than cisplatin widely used in clinic under the same conditions. Meanwhile, complexes could effectively inhibit cell migration and colony formation. Complexes could interact with protein and transport through serum protein, effectively catalyzing the oxidation of nicotinamide-adenine dinucleotid and inducing the accumulation of reactive oxygen species (ROS, 1O2), which confirmed the anticancer mechanism of oxidation. Furthermore, laser scanning confocal detection indicates that these complexes can enter cells followed by a non-energy-dependent cellular uptake mechanism, effectively accumulating in the lysosome (Pearson’s colocalization coefficient: ?0.90), leading to lysosome damage, and reducing the mitochondrial membrane potential (MMP). Taken together, ferrocene-appended iridium(III) complexes possess the prospect of becoming a new multifunctional therapeutic platform, including lysosome-targeted imaging and anticancer drugs.

Ferrocenylalkylation processes under electrospray ionization conditions

The electrospray ionization behavior of some ferrocenylalkylazoles CpFeC5H4CH(R)Az (AzH are derivatives of imidazole, pyrazole, triazole and their benzo analogs; R = H, Me, Et, Ph), ferrocenylalkanols CpFeC5H4CH(R)OH (R = H, Me), and mixtures of the latter with azoles was studied. The electrospray ionization mass spectra of these compounds, in addition to the molecular ion [M] +¡¤, the protonated molecule [M + H]+, and ferrocenylalkyl cation [FcCHR]+ peaks, exhibit also intensive peaks for the binuclear ions [(FcCHR)2X]+ (X = Az or O), resulting from ferrocenylalkylation of the initial compounds with the ferrocenylalkyl cations. Electrospray ionization of an equimolar mixture of ferrocenylmethanol FcCH2OH and imidazole gives the protonated ferrocenylmethylimidazole molecule [FcCH2Im + H]+ and the [FcCH2(Im)2 + H]+ dimer, apart from the ions typical of each component, i.e., ferrocenylalkylation of azoles with the ferrocenylalkylcarbinols, known in the chemistry of solutions, takes place under electrospray conditions.

A Feedback Control Approach to Organic Drug Infusions Using Electrochemical Measurement

Goal: Target-controlled infusion of anesthesia is a closed-loop automated drug delivery method with a computer-aided control. Our goal is to design and test an automated drug infusion platform for propofol delivery in total intravenous anesthesia (TIVA) administration. Methods: In the proposed method, a dilution chamber with first-order exponential decay characteristics was used to model the pharmacodynamics decay of a drug. The dilution chamber was connected to a flow system through an electrochemical cell containing an organic film-coated glassy carbon electrode as working electrode. To set up the feedback-controlled delivery platform and optimize its parameters, ferrocene methanol was used as a proxy of the propofol. The output signal of the sensor was connected to a PI controller, which prompted a syringe pump for feedback-controlled drug infusion. Results: The result is a bench-top drug infusion platform to automate the delivery of a propofol based on the measurement of concentration with an organic film-coated voltammetric sensor. Conclusion: To evaluate the performance characteristics of the infusion platform, the propofol concentration in the dilution chamber was monitored with the organic film-coated glassy carbon electrode and the difference between the set and measured concentrations was assessed. The feasibility of measurement-based feedback-controlled propofol delivery is demonstrated and confirmed. Significance: This platform will contribute to high-performance TIVA application of intravenous propofol anesthesia.

Substituent effects on ferrocenes in aluminum chloride-butylpyridinium chloride molten-salt mixtures

The visible absorption spectra and reduction potentials of 11 ferrocenes containing electron-withdrawing substituents were determined in an N-n-butylpyridinium chloride-aluminum chloride molten salt. When the substituent(s) on the cyclopentadienyl ring(s) of ferrocene were varied, the reduction potential was caused to range over 1.25 V, and the wavelength for maximum absorption of visible light was varied by nearly 200 nm. These changes are greater than have been observed for similar ferrocenes in other nonaqueous solvents. Evidence is presented for specific interactions of particular ferrocenes with the molten salt.

Synthetic Route of 1271-48-3, Chemistry is the experimental science by definition. We want to make observations to prove hypothesis. For this purpose, we perform experiments in the lab. 1271-48-3, Name is 1,1′-Ferrocenedicarboxaldehyde,introducing its new discovery.

24- and 26-membered macrocyclic diorganotin(IV) bis-dithiocarbamate complexes with N,N?-disubstituted 1,3- and 1,4-bis(aminomethyl)benzene and 1,1?-bis(aminomethyl)ferrocene as spacer groups

The potassium bis-dithiocarbamate (bis-dtc) salts of 1,3- bis(benzylaminomethyl)benzene (1,3-Bn-ambdtc), 1,3-bis(iso-butylaminomethyl) benzene (1,3-iBu-ambdtc), 1,4-bis(benzylaminomethyl)benzene (1,4-Bn-ambdtc), and 1,4-bis(iso-butylaminomethyl)benzene (1,4- iBu-ambdtc) were reacted with three different diorganotin dichlorides (R2SnCl2 with R = Me, nBu, and Ph) in 1:1 stoichiometric ratios to give the corresponding diorganotin bis- dithiocarbamates. Additionally, the dimethyltin bis-dithiocarbamate of 1,1?-bis(benzylaminomethyl)ferrocene (1,1?-Bn-amfdtc) was prepared. The resulting complexes have been characterized as far as possible by elemental analysis, FAB+ mass spectrometry, IR and NMR (1H, 13C, and 119Sn) spectroscopy, and single-crystal X-ray diffraction, showing that the tin complexes are dinuclear 24- and 26-membered macrocyclic species of composition [{R2Sn(bis-dtc)}2]. As shown by 119Sn NMR spectroscopy, the tin centers are hexa-coordinated in all cases; however, two different coordination environments are possible, as detected by single-crystal X-ray diffraction. In the dimethyltin derivatives of 1,3-Bn-ambdtc, 1,3-iBu-ambdtc, 1,4-Bn-ambdtc, and 1,1?-Bn-amfdtc and the di-n-butyltin derivative of 1,3- iBu-ambdtc, the metal atoms are embedded in skewed-trapezoidal- bipyramidal coordination polyhedra with asymmetrically coordinating trans-oriented dtc groups. In contrast, in the diphenyltin derivative 1,3- iBu-ambdtc, the metal centers have distorted octahedral coordination with symmetrically coordinating cis-oriented dtc functions. Thus, for the complexes derived from 1,3-Bn/iBu-ambdtc, two different macrocyclic structures were observed. In the dimethyl- and di-n-butyltin derivatives, the bridging bis-dtc ligands adopt U-shaped conformations, while in the case of the diphenyltin derivative, the conformation is L-shaped. Furthermore, two different macrocyclic ring conformations can occurr, which differ in the spatial orientation of the substituents attached to the nitrogen atoms (Bn or iBu). The dimethyltin derivatives of 1,4-Bn-ambdtc and 1,1?-Bn-amfdtc have cavities, in which aromatic rings are accomodated in the solid state.

IR spectral and X-ray single crystal study of hydrogen bonds and structure of nonamethylferrocenyl- and ferrocenylcarbinols in the solid state

The influence of different substituents in the Cp-ring and at the carbinol C atm on the character and stability of H bonds in crystals of FcCHROH and 9FcCHROH, Fc = C5H5FeC5H4; 9Fc = C5Me5FeC5Me4, (R = H, CH3, C6H5, C6F5) was studied by IR spectroscopy specifically in the nu(OH) region.In the crystals, molecules associate predominantly via intermolecular OH…O bonds.However, in some of the 9FcCHROH complexes, the intermolecular O-H…?(Cp) H bonds are also formed.The major type of self-association in compounds with R = Mes is OH…?(Mes) H-bonding.It was found from the X-ray structural data for the 9FcCHMesOH that the Mes plane is almost perpendicular to each Cp ring plane.No intermolecular OH…O bonds are formed because of intramolecular shielding of the OH group.The stability of the intermolecular hydrogen bonds is determined by steric rather than electronic factors, the most stable intermolecular hydrogen bonds being formed in the case of primary carbinols.
