Synthesis, characterization, and binding assessment with human serum albumin of three bipyridine lanthanide(III) complexes

In this work, the terbium(III), dysprosium(III), and ytterbium(III) complexes containing 2, 2?-bipyridine (bpy) ligand have been synthesized and characterized using CHN elemental analysis, FT-IR, UV?Vis and 1H-NMR techniques and their binding behavior with human serum albumin (HSA) was studied by UV?Vis, fluorescence and molecular docking examinations. The experimental data indicated that all three lanthanide complexes have high binding affinity to HSA with effective quenching of HSA fluorescence via static mechanism. The binding parameters, the type of interaction, the value of resonance energy transfer, and the binding distance between complexes and HSA were estimated from the analysis of fluorescence measurements and Foerster theory. The thermodynamic parameters suggested that van der Waals interactions and hydrogen bonds play an important role in the binding mechanism. While, the energy transfer from HSA molecules to all these complexes occurs with high probability, the order of binding constants (BpyTb?>?BpyDy?>?BpyYb) represents the importance of radius of Ln3+ ion in the complex-HSA interaction. The results of molecular docking calculation and competitive experiments assessed site 3 of HSA, located in subdomain IB, as the most probable binding site for these ligands and also indicated the microenvironment residues around the bound mentioned complexes. The computational results kept in good agreement with experimental data.

Substituent effects of 1,2-dithiole groups on the electrochemical oxidation of some ferrocenyl-1,2-dithiole compounds

New ferrocenyl compounds substituted by sulfur containing groups were synthesized leading to ferrocenyl-3H-1,2-dithiole-3-thiones and related compounds. The substituent of the ferrocene was a [3-thioxo-3H-1,2-dithiol]-4 or 5-yl, a [3-oxo-3H-1,2-dithiol]-4 or 5- yl or a [3-methylsulfanyl-3H-1,2-dithiolium]-4 or 5-yl cation group. Their anodic behavior was studied by cyclic voltammetry at a Pt electrode in aprotic solvent. All synthesized ferrocenes exhibited a one-electron reversible oxidation leading to the corresponding ferricinium cation. At low potential scan, the irreversible oxidation of 5-ferrocenyl-3H-1,2-dithiole-3-thione was observed and attributed to a dimerization involving the dithiolethione group. Redox potential of the reversible oxidation allowed the determination of the electronic effect of the 1,2-dithiole groups. The Hammett sigmap constants of the dithiole substituents were obtained from linear correlation between oxidation potentials and electronic effects. The results showed that the [3-thioxo-3H-1,2-dithiol]-5-yl and the [3-methylsulfanyl-3H-1,2-dithiolium]-5-yl cation groups were strong inductive electron withdrawing substituents characterized by sigmap values of 0.55 and 0.97, respectively.

Synthesis of ferrocenyl-containing silicone rubbers via platinum-catalyzed Si?H self-cross-linking

Self-cross-linkable ferrocenyl-containing polymethylhydrosiloxanes were synthesized. Karstedt’s catalyst and cis-[PtCl2(BnCN)2] were examined as cross-linking catalysts at room temperature for the reaction between Si?H groups of the ferrocenyl-containing polymethylhydrosiloxanes. Cis-[PtCl2(BnCN)2] is an effective catalyst that allows cross-linked ferrocenyl-containing silicones (silicone rubbers) to be obtained with no visible mechanical defects (bubbles or cracks) compared with Karstedt’s catalyst. The ferrocene content of the ferrocenyl-containing silicone rubbers was found to be approximately 50?wt.% by energy-dispersive X-ray analysis. Compared with cross-linked non-modified polymethylhydrosiloxanes, the ferrocenyl-containing silicone rubbers exhibited improved tensile properties (the tensile strength increased from 0.47 to 0.75?MPa) and a 1.5?2.5 times lower cross-linking degree. The surface resistivity of the ferrocenyl-containing silicone rubbers (50?wt.% ferrocenyl units) was approximately 7 ¡Á 109?Omega/?, which was 10,000 times lower than that of pure polymethylhydrosiloxane. The obtained flexible electroactive ferrocenyl-containing silicone rubbers can potentially be applied as coatings for electronic and electrostatic-sensitive devices, interfaces, and sensors.

Ratiometric electrochemical detection of Pd???pi interactions: application towards electrochemical molecular logic gates

The widespread and large scale use of platinum group metals, especially palladium, in a wide variety of industrial applications has seen their levels in wastewater streams, roadside dust and even pharmaceuticals significantly rise over recent years. Due to the possible environmental damage and potential health risk this may cause, there is now substantial demand for inexpensive, efficient and robust methods for the detection of palladium. Based upon self-immolative linker technologies, we have designed and synthesised a number of allyl ether-functionalised electrochemical probes to determine the optimum probe structure required to deliver a ratiometric electrochemical detection method capable of achieving a limit of detection of?<1?mg/mL within 20?min through the use of disposable screen-printed carbon electrodes. Combined with an enzymatic assay, this method was then used to achieve a proof-of-principle ratiometric electrochemical molecular logic gate.

Synthesis, characterisation and properties of ferrocenylalkylimidazolium salts

New ferrocenylalkylimidazolium salts [Fc(CH2)n(C3H3N2)R]X- were synthesised through the incorporation of green chemistry principles of atom economy and when feasible under solvent-free conditions. The products comprise a series of salts all characterised by the ferrocenyl moiety with variations in the length of the linker alkyl chain (n), the size of the imidazolium alkyl substituent (R) or the electronic nature of the counter-ion (X-). The dependence of the physical and electronic properties of the salts on the three main structural variants was studied. It was found that variation in the steric size of the R group has the most profound influence on the melting points of the ionic liquids. The compounds were fully characterised by IR, 1H and 13C NMR, MS and melting point determinations.

Iron-catalyzed reductive coupling of nitroarenes with olefins: Intermediate of iron-nitroso complex

Using a single half-sandwich iron(II) compound, CpFe(1,2-Ph2PC6H4S)(NCMe) (Cp- = C5Me5-, 1) as a catalyst, reductive coupling of nitroarenes with olefins has been achieved by a well-defined iron(II)/(EtO)3SiH system. Through either inter- or intramolecular reductive coupling, various branched amines and indole derivatives have been directly synthesized in one-pot. Mechanistic studies showed that the catalysis is initiated by activation of nitroarenes by the iron(II) catalyst with silane, generating iron-nitrosoarene intermediate for the C-N bond coupling.

Stochastic Collision Nanoelectrochemistry: A Review of Recent Developments

Single-entity electrochemistry mainly focuses on the properties of single nanoscale systems, which provides a new avenue of studying electrochemical processes at the nanoscale rather than in complex ensemble systems. Stochastic collision nanoelectrochemistry (SCNEC), which has emerged as a convenient and fast single-entity electrochemical analysis method, has gone through significant improvements over the past few years. As a powerful tool for the establishment of multiple analytical strategies, SCNEC has broad applications in electrochemical analysis, catalysis, biosensing, and so forth. This technique is especially promising for the rapid analysis of a single entity with respect to size, concentration, aggregation, and kinetic studies. In this Minireview, we summarize the basic principles and experimental techniques of SCNEC and give a brief overview of the cutting-edge developments in SCNEC over the past 3 years.

A New Multicomponent Multicatalyst Reaction (MC)2R: Chemoselective Cycloaddition and Latent Catalyst Activation for the Synthesis of Fully Substituted 1,2,3-Triazoles

A multicomponent multicatalyst reaction (MC)2R for constructing fully substituted 1,2,3-triazoles is reported. An application of chemoselectivity and latent catalysis in a sequence of multicatalytic reactions confers control over a number of undesired processes, where all of the reagents coexist in the same reaction vessel. The sequence of a chemoselective copper-catalyzed azide alkyne cycloaddition followed by a palladium/copper-catalyzed Sonogashira cross-coupling afforded 1,2,3-triazoles regioselectively with good to high yields and a broad scope.
