Zn-polyphenol chelation: Complexes with quercetin, (+)-catechin, and derivatives: II Electrochemical and EPR studies

In this work, we have studied the formation of complexes between flavonols, (quercetin, rutin, quercitrin, kaempferol, luteolin, tamarixetin) and flavanols ((+)-catechin, (-)-epicatechin), flavanonol, (+)-taxifolin, and Zn acetate in two hydro-organic media at neutral pH in the absence of oxygen. The complexation was first studied by cyclic voltammetry. Then preparative electrolysis have been attempted followed by coulometry, UV-Vis optical absorption and circular dicroism spectroscopies for characterizing the oxidized compounds. Spectroelectrochemistries monitored either in the UV-Vis or in the EPR spectrometers at room temperature have been also used and we have identified o-semi-quinone intermediates in some cases. Different behaviour vis-a-vis the complexation by Zn2+ according to the molecular structures of these different families of polyphenols have been found. Some of them are more easily oxidizible.

The study of regioselectivity of ferrocenylalkylation of N, S-heterocycles in aqueous-organic media

Regioselectivity of ferrocenylalkylation reaction of mercaptoheterocycles with ferrocenylcarbinoles in biphasic aqueous-organic media was studied. The structures of compounds were assigned on the basis of NMR spectra and 1H/13C heteronuclear correlations. X-ray determination of molecular structures of 1-(ferrocenyl(phenyl)methyl)pyrrolidine-2-thione 5f, 4, 5-dihydro-1-(1-ferrocenylmethyl)-1H-imidazole-2-thiol 7a and 4, 5-dihydro-1-(1-ferrocenyl-2methylpropyl)-1H-imidazole-2-thiol 7e were carried out.

Antimicrobial activity of organometallic isonicotinyl and pyrazinyl ferrocenyl-derived complexes

Isonicotinyl and pyrazinyl ferrocenyl-derived complexes were prepared using various hydrazides and ferrocenyl aldehydes. Three heterobimetallic complexes were also synthesized from the Schiff base-derived isonicotinyl ferrocene complex using various platinum group metal dimers based on ruthenium, rhodium and iridium. All complexes were evaluated in vitro for antimycobacterial and antiparasitic activity. Against Mycobacterium tuberculosis H37Rv, the platinum group metal complexes showed glycerol-dependent antimycobacterial activity. The antiplasmodial activities against the NF54 chloroquine-sensitive strain of Plasmodium falciparum of some compounds were moderate, while some complexes also showed promising activity against Trichomonas vaginalis. Incorporation of the ferrocenyl-salicylaldimine moiety resulted in enhanced antimicrobial activity compared to the non-ferrocenyl compound in some cases. The bimetallic iridium-ferrocene isonicotinyl complex exhibited superior antitrichomonal activity relative to its organic counterpart, isoniazid. Furthermore, all these compounds, when screened on several normal flora bacteria of humans, showed no effect on the microbiome, emphasizing the selection of these compounds for these pathogens. The promising antimicrobial activities of the complexes thus supports incorporation of ferrocene as part of existing antimicrobial therapies in order to alter their biological activities favorably.

Synthesis of ferrocene tethered open and macrocyclic bis-beta-lactams and bis-beta-amino acid derivatives

New bioorganometallic ferrocene derivatives are synthesized through a Diversity Oriented Synthesis strategy. Easily available ferrocene bisimines have been transformed into open ferrocenyl bis-beta-lactams. These compounds have demonstrated to be versatile synthons used in further transformations into new ferrocene bis-beta-amino acids. Carefully selected substituents submitted to ring closing metathesis (RCM) and Cu-catalyzed oxidative alkyne coupling conditions have also allowed the conversion of open substrates into ferrocenic macrocyclic bis-beta-lactams.

The stability of nonporous and macroporous titania thin films in aqueous electrolyte solutions

A simple electrochemical approach was used to evaluate the stability and porosity of titania and silica thin films spin coated on electrode surfaces. This approach involved monitoring the magnitude of the Faradaic current of diffusing redox probes at the modified electrode surfaces over the course of a week to 4.5 months. Relatively nonporous films were examined as well as films templated with polystyrene latex spheres. The results show that templated titania films were significantly more porous compared to non-templated films. After the defect sites in the templated films were blocked, their long-term stability in aqueous electrolyte was evaluated. For titania, blocking was done by spin coating a dilute titania sol on the top of the film whereas for silica, the film was soaked in octyltrimethoxysilane. Both types of titania films (templated and non-templated) were found to be significantly more stable than the corresponding silica films, showing no signs of deterioration in simple electrolyte solutions during the entire evaluation period. In contrast, silica films showed significant deterioration in as little as 3 days. The enhanced stability of the titania films relative to silica films in near neutral electrolyte solutions was attributed to the differences in the point of zero charge of the oxide films.

Synthesis of mono and doubly alkynyl substituted ferrocene and its crystal engineering using -C-H¡¤¡¤¡¤O supramolecular synthon

Mono and doubly alkynyl substituted ferrocene complexes, [Fc(CH2OCH2C{triple bond, long}CH)n], 2-3 (2: n = 1; 3: n = 2; Fc = ferrocene) have been synthesized from the room temperature reaction of mono and 1,1?-dihydroxymethyl ferrocene, Fc(CH2OH)n, 1a-b (1a: n = 1; 1b: n = 2) and propargyl bromide, in modest to good yields. These new ferrocene derivatives have been characterized by mass, IR, 1H, 13C NMR spectroscopy, and molecular structures of compound 2 and 3 were unequivocally established by single crystal X-ray diffraction study. The crystal structure analysis revealed that 2 and 3 consist of infinite 1D zig-zag hydrogen bonded chains and 2D microporous hydrogen bonded network of molecules, linked by intermolecular C-H¡¤¡¤¡¤O hydrogen bonding. The molecular structures of both 2 and 3 are further stabilized by C-H¡¤¡¤¡¤pi interactions.
