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.

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.

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.

Electrocatalytic oxidation and voltammetric determination of sulfamethazine using a modified carbon electrode with ionic liquid

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.

Stilbene analogues incorporating the Co(eta4-C 4Ph4)(eta5-C5H4-) end group

A number of organometallic stilbenes of the general type [Co(eta4-C4Ph4)(eta5-C 5H4CHCHR] are reported where R is C6H 4X-4 (X = H, OMe, Br, NO2), 1-naphthyl, 9-anthryl, 1-pyrenyl, (eta5-C5H4)Co(eta4- C4Ph4), and (eta5-C5H 4)Fe(eta5-C5H4Y) {Y = CHO, CHC(CN)2 and CHCHC5H4-eta5) Co(eta4-C4Ph4)}. They were prepared by Wittig or Horner-Wadsworth-Emmons reactions which yield both E and Z or only E products respectively. The isomers were separated and all compounds characterised by standard spectroscopic techniques as well as by X-ray diffraction methods in many cases. The electrochemistry of the stilbene analogues in dichloromethane solution is also reported. In most, the (eta5-C5H4)Co(eta4-C 4Ph4) functional group undergoes a reversible one-electron oxidation. For those molecules that also include (eta5-C 5H4)Fe(eta5-C5H4Y), this is preceded by the reversible oxidation of the ferrocenyl group. Spectroscopic and structural data suggests that for most compounds there is little electronic interaction between Co(eta4-C4Ph 4)(eta5-C5H4) and the R end groups which are effectively independent of one another. The only exceptions to this are Z and E-[Co(eta4-C4Ph4) (eta5-C5H4CHCHC6H 4NO2-4], and [Co(eta4-C4Ph 4)(eta5-C5H4CHCHC 5H4-eta5)Fe{eta5-C 5H4CHC(CN)2}] where the electronic spectra are respectively consistent with a significant Co(eta4-C 4Ph4)(eta5-C5H4)/ NO2 donor/acceptor interaction and a less significant Co(eta4-C4Ph4)(eta5-C 5H4)/C(CN)2 one. However, OTTLE studies show that in the electronic spectra of [Co(eta4-C4Ph 4)(eta5-C5H4CHCHR]+ there are low energy absorption bands (950-1800 nm) which are attributed to R ? Co(eta4-C4Ph4)(eta5- C5H4)+ or, when R is a ferrocenyl-base group, Co(eta4-C4Ph4)(eta5-C 5H4) ? (eta5-C5H 4)Fe(eta5-C5H4Y)+ charge transfer transitions. The ferrocenyl compounds undergo cis/trans isomerisation on the OTTLE experiment timescale.
