Synthesis, spectroscopy, X-ray analysis and in vitro antiproliferative effect of ferrocenylmethylene-hydrazinylpyridazin-3(2H)-ones and related ferroceno[d]pyridazin-1(2H)-ones

Synthesis, structure determination and in vitro antiproliferative assay of a series of novel ferrocenenyl hydrazones containing 4-halopyridazin-3(2H)-one fragment(s) and three representative N-arylsubstituted (Sp)-ferroceno[d] pyridazinones are presented. The model compounds can be considered as different assemblies of the potential binding sites capable of establishing interactions including hydrogen bonds and pi-pi interactions with the relevant residues of biomolecules. Their in vitro antiproliferative effect was investigated against four tumorous cell lines by the 3-(4,5-dimethylthiazol-2-yl)-2,5- diphenyltetrazolium bromide (MTT)-assay. Our data indicate that bis-hydrazone of 1,1?-diformylferrocene carrying N-benzyl substituents and a chloropyridazinyl-substituted ferroceno[d]pyridazinone display significant activity on each cell lines investigated. The efficiency of the latter drug candidate and one N-benzyl mono-hydrazone on A2870 cell line is comparable to that of cisplatin. The constitution and relative configuration of the model compounds were established by 1H, 13C and 15N NMR methods. The structures of a mono- and bis-ferrocenylhydrazone containing 4-bromopyridazinone unit(s) were confirmed by single crystal X-ray diffraction.

Hydrogen bond donation to the heme distal ligand of Staphylococcus aureus IsdG tunes the electronic structure

Abstract Staphylococcus aureus IsdG catalyzes the final step of staphylococcal iron acquisition from host hemoglobin, whereby host-derived heme is converted to iron and organic products. The Asn7 distal pocket residue is known to be critical for enzyme activity, but the influence of this residue on the substrate electronic structure was unknown prior to this work. Here, an optical spectroscopic and density functional theory characterization of azide- and cyanide-inhibited wild type and N7A IsdG is presented. Magnetic circular dichroism data demonstrate that Asn7 perturbs the electronic structure of azide-inhibited, but not cyanide-inhibited, IsdG. As the iron-ligating alpha-atom of azide, but not cyanide, can act as a hydrogen bond acceptor, these data indicate that the terminal amide of Asn7 is a hydrogen bond donor to the alpha-atom of a distal ligand to heme in IsdG. Circular dichroism characterization of azide- and cyanide-inhibited forms of WT and N7A IsdG strongly suggests that the Asn7¡¤¡¤¡¤N3 hydrogen bond influences the orientation of a distal azide ligand with respect to the heme substrate. Specifically, density functional theory calculations suggest that Asn7¡¤¡¤¡¤N3 hydrogen bond donation causes the azide ligand to rotate about an axis perpendicular to the porphyrin plane and weakens the pi-donor strength of the azide ligand. This lowers the energies of the Fe 3d xz and 3d yz orbitals, mixes Fe 3d xy and porphyrin a 2u character into the singly-occupied molecular orbital, and results in spin delocalization onto the heme meso carbons. These discoveries have important implications for the mechanism of heme oxygenation catalyzed by IsdG.

First synthesis of 1,1?-ferrocene bis-aminophosphonic esters

The series of aminophosphonates bearing the 1,1? -bis-substituted ferrocenyl moiety was obtained by the addition of dialkyl phosphites to an azomethine bond of Schiff bases derived from 1,1?-ferrocene-bis-carboxaldehyde. This addition led to both diastereoisomeric forms demonstrating its behaviour to be contrary to the addition to terephthalic Schiff bases, which led exclusively to a meso -form.

Homotrimetallic oxazolo-ferrocene complexes displaying tunable cooperative interactions between metal centers and redox-switchable character

A synthetic procedure based on the aza-Wittig reaction of alpha-azidoacetyl ferrocene or 1,1?-bis(alpha-azidoacetyl)ferrocene with mono-, di-, and triacyl chlorides and triphenylphosphine has been developed to prepare the new homotrimetallic ferrocene complexes 6, 9, and 10 containing at least two oxazole rings in the conjugation chain. Complexes 9 and 10 exhibited three and two reversible redox processes, respectively, indicating significant electrostatic interaction between the iron centers in these complexes. Protonation properties of complexes 9-13 have been assessed by use of 1H NMR and cyclic voltammetry measurements.

Ferrocenyl aryl ethers can be synthesized in good yields by Cu(I)/phosphine-catalyzed coupling reactions from iodoferrocene or 1,1?-dibromoferrocene and various phenols in toluene, using Cs2CO3 or K3PO4 as a base. For the first time a solid-state structure of a ferrocenyl-1,1?-diaryl ether [1,1?-di(4-tert-butylphenoxy)ferrocene] has been determined from single-crystal X-ray data. The mixed ferrocenyl aryl ether 1-(4-tert-butylphenoxy)-1?-(2,4-dimethylphenoxy)ferrocene was prepared in a two-step synthetic protocol.

Emerging pnictogen-based 2D semiconductors: Sensing and electronic devices

Pnictogens are an intensively studied group of monoelemental two-dimensional materials. This group of elements consists of phosphorus, arsenic, antimony, and bismuth. In this group, the elements adopt two different layered structural allotropes, orthorhombic structure with true van der Waals layered interactions and rhombohedral structure, where covalent interactions between layers are also present. The orthorhombic structure is well known for phosphorus and arsenic, and the rhombohedral structure is the most thermodynamically stable allotropic modification of arsenic, antimony, and bismuth. Due to the electronic structure of pnictogen layers and their semiconducting character, these materials have huge application potential for electronic devices such as transistors and sensors including photosensitive devices as well as gas and electrochemical sensors. While photodetection and gas sensing applications are often related to lithography processed materials, chemical sensing proceeds in a liquid environment (either aqueous or non-aqueous) and can be influenced by surface oxidation of these materials. In this review, we explore the current state of pnictogen applications in sensing and electronic devices including transistors, photodetectors, gas sensors, and chemical/electrochemical sensors.

Electrically transmissive alkyne-anchored monolayers on gold

Well-ordered, tightly-packed (surface coverage 0.97 ¡Á 10-9 mol cm-2) monolayer films of 1,4-bis((4-ethynylphenyl)ethynyl)benzene (1) on gold are prepared via a simple self-assembly process, taking advantage of the ready formation of alkynyl C-Au sigma-bonds. Electrochemical measurements using [Ru(NH3)6]3+, [Fe(CN)6]3-, and ferrocenylmethanol [Fe(eta5-C5H4CH2OH)(eta5-C5H5)] redox probes indicate that the alkynyl C-Au contacted monolayer of 1 presents a relatively low barrier for electron transfer. This contrasts with monolayer films on gold of other oligo(phenylene ethynylene) derivatives of comparable length and surface coverage, but with different contacting groups. Additionally, a low voltage transition (Vtrans = 0.51 V) from direct tunneling (rectangular barrier) to field emission (triangular barrier) is observed. This low transition voltage points to a low tunneling barrier, which is consistent with the facile electron transport observed through the C-Au contacted self-assembled monolayer of 1.
